How to Use Firefox Hello Video Chat

How to start chatting with webRTC, the no-hassle, in-browser voice and video tech



There's a relatively new technology built in to most browsers that could revolutionize the way you talk with your friends and family. Called webRTC, the HTML 5-based tech could one day replace the need for third-party plugins from services like Google Hangouts or Skype, offering voice and video chat capabilities natively in your browser.
Even better, most implementations of the technology don't require an account of any kind. Chats take place on a web page that you set up on a site that supports webRTC. To get chatting all you have to do is share a link to the web page and you'll be up and running in no time. Talk about hassle free!
If you'd like to give webRTC a try, here's how to get started.

Your browser

Many current browsers for the PC support webRTC, including Chrome, Firefox, and Opera. Apple's Safari doesn't and neither does Microsoft's Internet Explorer; however, Microsoft-owned Skype plans on supporting webRTC in the future with its newly announced Skype for Web project.
If you want to go mobile Chrome, Firefox, and Opera support webRTC on Android. On iOS you can try Bowser.

Get chatting

Once you've got your browser picked out it's time to start using webRTC. Sites that support webRTC include appear.in, talky.io, and apprtc from webRTC.org.
Most of the sites that support webRTC are incredibly easy to use and don't require a lot of technical prowess. For our purposes I'll just show you one example and leave it to you to apply that knowledge to another service.
talky
Talky.io is one of several web sites that support webRTC chats.
Let's use Talky as an example. On the Talky landing page, you have to enter a name for your conversation. It can be pretty much anything you want so let's call it "no hassle example." Next, you press the pink Let's go! button and you'll be taken to a conversation web page. A settings warning should appear on your browser asking for permission to access your webcam and microphone. 
Now all you have to do is share the link to the web page you're on, wait for others to join, and you're ready to go.
firefoxbetawebrtc
Mozilla is testing a built-in webRTC chat button for Firefox.
If you're running the test version of Firefox there's a slightly easier method to get chatting. The latest beta versions of Firefox come with a new chat button with webRTC, supported by Telefonica--one of Mozilla's partners for Firefox OS.
In the case of Firefox, after you click the chat button, click the Start a conversation link. A pop-up window will appear in the bottom of Firefox asking you to name the conversation and then giving you the opportunity to email or copy the link to the chat's web page.
Just to be clear, it doesn't matter if you use Firefox and your chat buddies use Chrome or Opera. As long as everyone is using a browser that supports webRTC there shouldn't be any compatibility problems.
That's about all there is to webRTC. In my experience, the call quality isn't quite as good as you'll experience on Hangouts or Skype, but it'll get there eventually. In the meantime, happy chatting.

Are you using the most secure and private web browser?

WhiteHat Aviator
Credit: WhiteHat Security

Aviator web browser, created by a WhiteHat Security, is setup to maximize privacy and security safeguards by default. Simply download OS X or Windows versions and then start surfing in private, protected mode without being tracked. You are not a product being sold in exchange for this free software.

It’s up to each of us to be proactive about security and privacy; it’s risky to trust a company to manage your privacy in a manner that benefits you the most and not them. If you could have a browser that offered security, privacy and speed for free, then why not try it?
WhiteHat Security originally developed Aviator as the company’s in-house browser, but eventually released Aviator web browser in two flavors, OS X and Windows. It is billed as “the web’s most secure and private browser.” Users simply install the browser and it’s setup to maximize privacy and security safeguards by default. Unlike Chrome or Firefox, you don’t need to get add-ons or extensions to configure privacy and security. Those protections are built into Aviator, but since the browser uses open-source Chromium code, it does support “tens of thousands of extensions.”
Aviator with Disconnect WhiteHat Security
Unlike Google with Chrome, Microsoft with Internet Explorer and even Mozilla with Firefox, which profit from online advertising, WhiteHat has no advertising partners and does not sell your data. You are not a product being sold in exchange for free software.
Aviator comes configured with the Disconnect extension, meaning bye-bye “privacy-destroying tracking.” Aviator’s search engine choices also come with Disconnect, meaning you are using a “privacy-enhanced default search engine.” It also comes with the User-Agent Switcher extension; websites identify browsers by user agents, but this extension allows you to appear as if you are browsing via Chrome, IE, iOS, Android, Windows Phone, Firefox, Opera or Safari.
Aviator extensions WhiteHat Security
When you surf to a page that contains cookies, you will see cookies with a red X on it, which indicates “This page was prevented from setting cookies.” Plugin has a similar red X, blocked on the page by default, but you have options to always allow the plug-in, run plug-in this time, and manage plug-ins.
Aviator blocks cookies and plugins WhiteHat Security
Aviator cookies
The security and privacy benefits are why I like Aviator. The browser launches in “protected” (private) mode, protecting your privacy by default by not logging your history, cookies, or browser cache. Ads and other hidden online trackers are blocked; this also protects you from malvertising (malicious advertising). Third-party cookies are also not allowed and Aviator automatically cleans locally stored data when you exit the browser. In WhiteHat’s words, “There is no need to constantly make it your mission to keep from being invisibly tracked and spied on.”
Aviator options
Aviator advanced settings for privacy and passwords
Why are Ghostery, Adblock Plus or Privacy Badger not also default extensions? Robert Hansen, aka @RSnake, Vice President of WhiteHat Security’s WhiteHat Labs was kind enough to answer my questions.
Robert Hansen: Ghostery and Privacy Badger are mostly redundant, and Adblock Plus allows ads from companies like Google, which totally defeats the purpose of the software. But if you want a feature from one of those plugins or feel that Disconnect is missing something, yes, of course you can install any plugin you like.
Are there any plans for Aviator to be offered as a mobile browser for iOS or Android?
Robert Hansen: It's unlikely in the near term. Though, that is always an option. The major hurdle is actually the manufacturers who don't like mobile browsers.
Might you offer a security/privacy-minded suggestion for a mobile browser?
Robert Hansen: Disconnect offers similar functionality to their browser extension on mobile - that is probably the best option available, though not as feature rich from a privacy/security standpoint as Aviator is which combines their technology with a number of our own techniques.
You can find more about Disconnect here; the free mobile app for iOS can be downloaded from iTunes and from Google Play for Android where it is lovely to see “Disconnect Search does not require any special permissions.” (There is also a Disconnect Secure Wireless app.)
If you are curious how Aviator stacks up against other browsers in a simple HTML5 test, then Aviator scored 492 out of 555 points, compared to 475 using Firefox 34, 512 using Chrome 39, 376 using IE 11 and 429 using Safari 8.
HTML5 test Aviator vs others HTML5
Do something good for yourself security-and-privacy-wise. If you haven’t tried Aviator yet, then I encourage you to “take flight” and start 2015 right.

Microsoft Making Lightweight 'Spartan' Browser for Windows 10



A new report sheds some light on Microsoft's plans for a new browser in Windows 10.
The Redmond giant will reportedly include the new browser, said to be an overhauled version of the Internet Explorer (IE), in its latest build of Windows and might even show it at the scheduled 'The Next Chapter' event for Microsoft Windows 10 on January 21.
ZDNet in a report citing sources claims that Microsoft has codenamed the new browser as "Spartan", and suggests it is not an upgrade of the IE11. It adds that the IE "Spartan" will pack several new features and will look more like Chrome and Firefox, apart from also supporting extensions. It also notes that the new browser will be a "lightweight browser."
The report cites Thomas Nigro, a Microsoft Student Partner lead and developer of VLC, earlier this month to have heard of a new Microsoft browser in development in an episode of the LiveTile podcast.

"Spartan is still going to use Microsoft's Chakra JavaScript engine and Microsoft's Trident rendering engine (not WebKit)", sources noted to ZDNet.
The Windows 10 (desktop version) is said to ship with both IE "Spartan" and IE11. Sources suggest that IE "Spartan" will be available to download for both desktop and mobile/ tablet versions of Windows 10. The report adds that Microsoft is yet to finalise the name of IE "Spartan".

It also speculates that the IE "Spartan" might not be functional for inclusion in the 'Windows 10 January Technical Preview' and even in mobile preview build that is likely to be available to testers early next year. "It may not show up in the test builds until some point later," it adds.

Earlier this month, an early build of the Windows 10 was leaked showing numerous changes.
In the leaked build, Microsoft was seen to have made some visible changes such as new wallpaper showing upfront alongside Cortana integration. The video showed Cortana would be present on the task bar with search option. Interestingly, the voice-based virtual assistant app was seen to also support voice-commands; though the leaked 9901 build showed that the feature still required some updates to work.
The Redmond giant first announced Windows 10 in late-September.

Top 10 Best Firefox Security Add-ons

By Jay Garmon, by

The main reason most people switch from Internet Explorer to Firefox is to improve their browser security, but that doesn’t mean Firefox is bullet-proof. We offer up the 10 best add-ons to make everyone’s favorite opensource web browser even more secure.
Those of you who’ve read our Internet Safety Guide or our list of the 10 best general Firefox add-ons may find a few of these add-ons familiar, but you can never address security or privacy too often. Some of these add-ons have overlapping functionality — particularly as applies to cookie and password management — but redundant functionality in this area is a feature, not a bug.

1. Web of Trust (WOT) – You pretty much can’t read a Firefox security article without learning about the Web of Trust (WOT) add-on — and there’s good reason. WOT rates every site on the Internet for its security risk: green equals safe, amber equals worrisome and red means avoid like the plague. Simple, easy, and a must-have security measure. If you prefer a brand name, McAfee’s SiteAdvisor Firefox add-on offers similar functionality.

2. AdBlock Plus – The AdBlock Plus Firefox add-on says what it does, does what. AdBlock prevents most advertisements from loading — especially Flash ads and those layered takeover ads that slow your page loads down — including all the tracking cookies most ads slip into your system. Even if you aren’t paranoid about data-snooping, AdBlock will noticeably speed up your surfing.

3. LastPass – The LastPass Firefox add-on is the granddaddy of password managers. Create one master logon for LastPass itself and it will log you in to every other online service you’ve got an account with. Moreover, LastPass stops storing your passwords locally in the browser — where they can be hacked — and encrypts them into an online account you (and you alone) can access from anywhere. It also has some nice password generation and form auto-completion features, which makes account signups even safer and simpler.

4. BetterPrivacy – The BetterPrivacy Firefox add-on is designed to scrape away the most persistent tracking cookies that websites (and, especially, advertisers) use to profile your online activity. In particular, BetterPrivacy blows away Local Shared Objects (LSOs), the pernicious cookies left behind by Flash applications, videos and websites that most other extensions simply can’t erase.

5. NoScript – JavaScript makes a lot of interesting functionality possible on the Web — including nefarious clickjacking attacks. The NoScript Firefox add-on permits only JavaScript from trusted domains to run in your browser, preventing any unsavory functions from occurring behind the scenes.

6. BugMeNot – It seems every site on Earth wants you to create an account to view their content these days — mostly so they can track your surfing (even offsite) and sell your data to advertisers (as in spammers). The easiest way to avoid this constraint is the BugMeNot add-on, which provides anonymous credentials for most major sites, allowing you to login without creating or using a “real” account.

7. SpamAvert.com – Where BugMeNot stops, the SpamAvert Firefox add-on picks up. SpamAvert creates quick, disposable e-mail addresses you can use to enroll at sites you don’t intend to visit again. The fake e-mail accounts allow you to complete registration, but they also take the hit for follow-up spam, keeping your real accounts clear of the clutter.

8. Beef TACO – The Beef Targeted Advertising Cookie Opt-out (TACO) blocks almost every type of tracking object from settling into your browser. If it’s designed to report your web activity to dataminers or advertisers — including the big dogs like Google, Facebook and Yahoo — the Beef TACO swats it away. Combine this with BetterPrivacy and you’ll be an ad-free phantom in no time.

9. Torbutton – For those that don’t know, Tor is a proxy surfing service that prevents even your ISP (or employer) from knowing exactly what web sites you’re visiting. The Torbutton Firefox add-on makes using the Tor service dead simple, which is a good thing given how easy it is to turn proxy-configuration a tangle of confusing options. If you want absolutely nobody to know where you’ve been online, the Torbutton is the place to start.

10. hideBad – Sometimes the biggest security or privacy threat is the one that’s right over your shoulder — literally. The hideBad Firefox add-on offers a browsing panic button that instantly closes every open tab in your browser (while saving the data so you can restore the session later) and replaces them with your homepage. It stops snooping eavesdroppers (and dangerously curious bosses) from knowing which web pages you were just surfing, which may be the most important security measure of them all.

If one of these add-ons doesn’t meet a specific security or privacy need, there are literally hundreds more Firefox security add-ons. If you’ve got a favorite, plug it in the comments section. With enough eyes, all bugs — and browser security holes — are shallow.
