Description of problem: Fully reproducible for me: upgrading to firefox-82.0.2-1.fc33.x86_64 breaks LastPass - I end up with a blank, white dropdown when I click on the toolbar. Downgrading to firefox-81.0.1-1.fc33.x86_64 fixes it. Some other web sites like FastMail never load, either. All returns to normal after downgrading. I see some reports on Twitter of similar behavior with gmail - https://twitter.com/jeffreytharris/status/1322611677599334400 Version-Release number of selected component (if applicable): firefox-82.0.2-1.fc33.x86_64 How reproducible: Always? Steps to Reproduce: At least for me this works: 1. Install Firefox 81, and LastPass extension. Login to lastpass 2. Upgrade to 82 Actual results: LastPass no longer works Expected results: LastPass works Additional info:
