How to change web browser default zoom settings

I recently upgraded one of my monitors to a big screen. I needed to change the default zoom level in my web browser from 100% to 90%. Below are how to do it in Firefox and Chrome (Chromium).





In Firefox, download the add-on called: Zoom Page WE.  Then Firefox will open every time at the desired page zoom level. See the below options dialog box.

In Chrome, it is built in. Got to Settings, Appearance, and select the default zoom level.

How to Stop Videos From Autoplaying

Most browsers don't make it easy, but you can block the interruptions
By Nicholas Deleon, January 22, 2018

You don’t have to let autoplaying videos get in the way when you go to such sites as ESPN and Bloomberg on your computer.
With a few tweaks of your browser settings or the installation of a small piece of software known as a browser extension, you’ll be able to browse the web on a laptop without having to worry about these videos, which begin playing automatically when you land on a site. (You can also turn off autoplay just in Facebook.)

The videos can be particularly annoying when you have several tabs open and can’t tell where the sound is coming from.
Blocking these videos not only cuts down on the distraction but can also keep you from needlessly burning through cellular data. That's handy if you’ve tethered your laptop to a smartphone at a café or have an internet service provider (ISP) with a monthly data cap.

And using a browser extension to block annoying autoplay videos has the added benefit of enhancing your overall online privacy. Those videos often come packaged with technology that can track your activity across the web for the benefit of advertisers.

“Searches about your health condition, your political engagement—you probably want to keep those secret,” and blocking autoplay videos can help, says Günes Acar, a research associate at Princeton University’s Center for Information Technology Policy. 

Browser Settings

Chrome: Google recently released Chrome 66, a new version of the popular desktop web browser, which blocks by default autoplay video that contains sound. To stop video that does not contain sound, you can use a third-party extension. (See the Extensions section below.)

As a developer, you may want to change Chrome autoplay policy behavior locally to test your website depending on user engagement. You can decide to disable entirely the autoplay policy by setting the Chrome flag "Autoplay Policy" to "No user gesture is required" at chrome://flags/#autoplay-policy .



Firefox: Mozilla’s recently revamped Firefox web browser offers a straightforward way to prevent unwanted videos from playing automatically as you hop from site to site. It's straightforward, but not something you'd stumble across by searching through pull-down menus.

First, you’ll need to access the browser’s advanced options by typing “about:config” (without the quotation marks) in the address bar and hitting Return. Next, search in the window for the “media.autoplay.enabled” setting and double-click it. This will disable most HTML5-based videos from playing on their own when you load a page.

This method won’t typically block videos in the older Adobe Flash format, but we’ll explain how to do so below.

To always allow or disallow autoplay for all media with sound, follow these steps:

1. Click the menu button and choose Preferences.
2. Select the Privacy & Security panel.
3. Scroll down to the Permissions section.
4. Next to For websites that autoplay sound, click the drop-down menu to choose Allow Autoplay or Don't Autoplay.

Safari: If you use Apple’s Safari browser as your daily driver, you may be wondering to yourself, “What’s autoplay video?” That’s because in the newest versions of Safari (starting with version 11, released in 2017), most autoplaying videos are blocked. Score one for Apple.

If you don’t have the latest version of Safari—say, if you’re using a work-provided laptop that has an older version of macOS—it’s a bit trickier to pull off.
You’ll need to open the application called Terminal (which is found in your Utilities folder), then paste in the following text (without the quotation marks): “defaults write com.apple.Safari IncludeInternalDebugMenu 1”.

This scary-looking string merely allows you to access an additional settings menu inside Safari called Debug. The next time you go to a website that has autoplaying video, you have to select the new Debug menu option at the top of the screen and then scroll down to Media Flags and Disable Inline Video. Goodbye, autoplaying video!

Extensions

As mentioned above, there's no built-in setting for Chrome that lets you turn off autoplay for videos, but you can do it by using a browser extension.
Regardless of which browser you use, extensions (also known as add-ons) are small pieces of software that add useful features. Some extensions, such as LastPass, help manage your passwords, while others, including the Evernote Web Clipper and OneNote Web Clipper, make it easier to archive snapshots of websites for later retrieval.

Some of the most popular extensions block ads from appearing on websites, with two, Adblock Plus and uBlock Origin, generally earning high reviews from users.

It just so happens that both Adblock Plus and uBlock Origin will block most autoplaying videos, including those based on the older Adobe Flash, right after you install them. No further configuration is needed.
Another extension, called NoScript, goes even further, and is able to scrub out entire sections of websites, including ads, videos, or blocks of text. The flip side of NoScript is that it’s generally more difficult to configure than either Adblock Plus or uBlock Origin, and can easily keep many websites from working for you if you accidentally configure it to block a vital script.

Facebook

With more than 2 billion active users, there’s a good chance that Facebook has an account for everyone reading this sentence. And while the company has recently announced changes to the News Feed that should limit the amount of video you see from brands and businesses, it still does allow autoplay videos. But Facebook also provides a setting that disables videos from playing automatically in your feed.
To use this setting, click the arrow icon on the top right-hand corner of your Facebook page and then click Settings. From here, select Videos on the left side of the window and change the Auto-Play Videos option from Default to Off.

Editor's Note: This story has been updated to include information about a new version of Chrome that blocks autoplay video that contains sound.
