Flickering drop downs

已張貼

I have this problem: https://support.mozilla.org/en-US/questions/820877

Except that all dropdowns are affected, including the ones that would let me open the settings menu and try the suggestions that worked for other people. These are pull down menus, address bar, settings menu, spellcheck, and any other pop-up/pull-down menus, including the right-click mouse menu.

I have tries F10 and alt, and minimizing and maximizing the window; these do not help.

Have you tried; Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Hi DuncanCV,

I understand you're having issues with flickering(disappearing?) with your screen views. By chance did you already try to uncheck Use hardware acceleration when available?

If you are unable to use the drop down menus, you could try opening Firefox in Safe Mode on your desktop.

To do this :

  1. Hold SHIFT
  2. Double click the Firefox Icon on your desktop
  3. You should see another icon pop down below on your toolbar
  4. Click on the icon and choose either Refresh Firefox to restart Firefox to your default settings or Start in Safe Mode with no extensions enabled.

Let me know if this helps you to try the suggested solutions.

Starting in safe mode from the terminal worked; I was unable to access safe mode by any other method.

It could be the work of one of your add-ons, or it could be Hardware Acceleration. How to disable Hardware Acceleration {web link}

Type about:addons<enter> in the address bar to open your Add-ons Manager. Hot key; <Control> (Mac=<Command>) <Shift> A)

In the Add-ons Manager, on the left, select Extensions. Disable a few add-ons, then Restart Firefox.

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All Of them.

If the problem continues, disable some more (restarting FF). Continue until the problem is gone. After, you know what group is causing the issue. Re-enable the last group ONE AT A TIME (restarting FF) until the problem returns.

Once you think you found the problem, disable that and re-enable all the others, then restart again. Let us know who the suspect is, detective.
