This start about a week ago (?) when there was a large update. Browser tabs keep flashing between dark and light. The only Theme that I have enabled in Firefox is the System theme - auto (it can’t be removed or disabled). It’s maddening. Please help. Thanks. Example 1 Example 2 Example 3 Fire…

So, I decided to start Firefox in safemode. It then gave me the option to Refresh Firefox, which I did. That seems to have done the trick, no more flashing. I’ll update this thread if the issue returns. Thanks all!

Firefox keep flashing (browser tabs and Firefox menus as well)
