When I'm on the web, sometimes the screen will glitch and boxes and black lines appear. Why is that happening and how can I stop it?

This is only in Firefox. It does not occur in Internet Explorer or Google Chrome. Here is a screenshot.

Hello

Some Firefox problems can be solved by performing a clean reinstall. This means that you remove Firefox program files, and then reinstall Firefox. Please follow these steps:

Note: You can print these steps or consult them in another browser.

  1. Download the latest version of Firefox from http://www.mozilla.org office and save the installer to your computer.
  2. Once the download is complete, close all Firefox Windows (click on quit in the file menu or Firefox).
  3. Remove the Firefox installation folder, which is located in one of these locations, by default:
    • Windows:

      • C:\Program Files\Mozilla Firefox
      • C:\Program Files (x 86) \Mozilla Firefox
    • Mac: Delete Firefox in the Applications folder.
    • Linux: If you have installed Firefox with the distribution-based package manager, you must use the same way to uninstall: see Install Firefox on Linux. If you have downloaded and installed the binary package from the Firefox download page, simply remove the folder firefox in your home directory.
  4. Now, go ahead and reinstall Firefox:
    1. Double-click on the downloaded Setup file and go through the steps in the installation wizard.
    2. Once the wizard is completed, click to open Firefox directly after clicking the Finish button.

More information on the resettlement of Firefox can be found here.

WARNING: Uninstaller or the use of Firefox and not run a third remover as part of this process, because who could permanently delete your Firefox data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and passwords saved. These can be recovered, unless they have been backed up on an external device!

Please report back to see if this helped you!

Thank you.
