Firefox v91.0 regressed rendering when compared to v90.0.2

When used FF v91.0 on managed (non-admin) mac user account, it is not rendering even Firefox Addons setting page properly (about:addons), does not render text for "Extensions", "Themes", and "Plugins" on the left side navigation.

I tried resetting firefox, disabling addons, etc none worked. Finally I ended up reverting back to prior version v90.0.2 and it worked.

Hi Thiru, many MacOS users are reporting display issues in Firefox 91.

As mentioned in the release notes, "Firefox [91] now automatically enables High Contrast Mode when "Increase Contrast" is checked on MacOS."

Is it possible you have that setting?

If so, please try one or both of these two options:

(1) Turn off the system-level setting. This appears to be the most effective workaround.

(2) Disable High Contrast mode in Firefox. See: Disable high contrast mode in Firefox.

For both changes, you might need to Quit Firefox and start it up again to see the normal display.

Any difference?
