Colors on dark theme sites are inverting/innacurate

Websites like Jira, GitHub, and Outlook that have dark themes are no longer usable for some reason. They worked fine yesterday, then today when I logged in they become unusable due to their colors being completely off. Lots of white text on white backgrounds where there used to not be white backgrounds, dark text on dark backgrounds where the text used to be white, buttons having inverted colors for some reason. If I switch them from dark theme to light theme, they work fine and the colors are correct. Very weird behavior, and makes Firefox unusable for me.

I am on Ubuntu for what its worth, and I made sure that my color settings are not set to "Never" override website colors. I tried all the different "Firefox Themes" and those had no impact on the issue. I have attached an image of what I am seeing when I visit GitHub.com.

Tip from a user in another thread:

There is a bug in version 2.3.3 of the Facebook Container extension that causes font color problems. An update (version 2.3.4) was released a few hours ago which should fix it. Firefox should find it on a routine check at some point, but to speed that up:

Open the Add-ons page. Either:

  • Ctrl+Shift+a (Mac: Command+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 right side, below the search box, there is a gear/wheel icon. Click that icon to drop the menu and then click "Check for Updates" to trigger an update.

Alternately, click Facebook Container to show its Details panel, scroll down below the description, and click "Check for Updates".
