Why aren't pull-down menus, behaving consistently, on Firefox on a Late-2021 M1-Max Sequoia v15.2 laptop Mac ? [2]

They work, properly, in Troubleshooting Mode -- is it the fault of my browser-extensions ?

I see you've been reporting this problem for a while:

Browser extensions are a logical thing to investigate, especially if you have any less commonly used ones. You can view, disable, and often remove unwanted or unknown extensions on the Add-ons page. Either:

  • Command+Shift+a (Windows: Ctrl+Shift+a)
  • "3-bar" menu button (or Tools menu) > Add-ons
  • type or paste about:addons in the address bar and press Enter/Return

In the left column of the Add-ons page, click Extensions. On the right side, find the "Manage Your Extensions" heading.

If there is at least one extension before the next heading -- "Recommended Extensions" -- please continue:

Then cast a critical eye over the list below that heading. Any extensions Firefox installs for built-in features are hidden from this page, so everything listed here is your choice (and your responsibility) to manage. Anything you don't mind turning off for 8 hours? Give it a try with those extensions disabled.

Any improvement?


Troubleshooting Mode also disables hardware acceleration of graphics. If you want to give that a test in regular mode -- it still requires a restart -- see: Firefox's performance settings.
