The bar in which the Black apple is located along with File Edit View History Bookmarks is blue. Then Tools Window Help up to the battery charge is brown/beige. Then the rest returns to blue. I have a photo which displays this problem very clearly.

The other problem I have is that I teach college courses online using a platform called Blackboard. While Firefox is the recommended web browser I cannot use it. When I scroll down a page in blackboard the text in the various documents disappears from the screen. It does not delete it, it just cannot be seen. All that remains is a white page.

Thanks so much!!!

Hi,

I suspect your theme is causing this behaviour. Can you switch to the Default theme to see if it goes away?

Changed theme to default, restarted firefox, and problem still there.

Also, I can't work with blackboard using firefox. I realize we have 2 problems here and we need to solve one first.

Hello,

Certain Firefox problems can be solved by performing a Clean reinstall. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:

Note: You might want to print these steps or view them in another browser.

  1. Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
  2. After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
  3. Delete the Firefox installation folder, which is located in one of these locations, by default:
    • Windows:
      • C:\Program Files\Mozilla Firefox
      • C:\Program Files (x86)\Mozilla Firefox
    • Mac: Delete Firefox from the Applications folder.
    • Linux: If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see Install Firefox on Linux. If you 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 the downloaded installation file and go through the steps of the installation wizard.
    2. Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.

Please report back again soon!

Hope this helps!
