Browser / Version: Firefox 141.0
Operating System: Mac OS X 10.15
Tested Another Browser: Yes Other

Problem type: Site is not usable
Description: Page not loading correctly
Steps to Reproduce:
This morning I'm seeing a "Something Went Wrong" message on x.com along with a red banner that tells me that Firefox's Enhanced Tracking Protection (Strict Mode) is known to cause problems on Firefox). I actually use custom mode, but tried switching it off for the site on the shield icon, and it still comes up with same alert screen.
It loads OK on phone app, and on Brave browser (which has quite a lot of protections set), so def an incompatibility with a current setting on Firefox, and just for first time this morning.
