Some websites won't show properly on firefox but work normally on other browsers.

Hello, When I try and go to some websites like https://source.android.com/ or https://developer.android.com/ the text on that webpage breaks. This seems to only happen on firefox and not other browsers such as brave or chrome. I have tried giving firefox a "tune up" and turning off my extensions with no luck. I have found a solution that works temporarily which is pressing ctrl + f5 to refresh the page but that stops working after I close the tab. Another problem is that on some websites such as https://www.metrobyt-mobile.com/ the navbar at the top wont load on firefox but would on other browsers. Any help with this would be greatly appreciated.

Diagnose Firefox issues using Troubleshoot(Safe) Mode {web link}

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


Many site issues can be caused by corrupt cookies or cache.

Make sure you allow pages to choose their own fonts.

  • Settings -> General: Fonts & Colors -> Advanced
    [X] "Allow pages to choose their own fonts, instead of your selections above"

If you use uBlock Origin make sure not to "block remote fonts".

I tried those steps with no luck. Clearing site and cookie data solves the problem temporarily but it comes back after I reopen the tab.

Allowing pages to choose their own fonts was already selected and uBlock Origin was not configured to block remote fonts so no success with that.

Just did a full reinstall and the problem still seems to persist.
