Firefox’s Enhanced Tracking Protection (Strict Mode) is known to cause issues on x.com
There were no “issues”; everything was working completely fine. This is a deliberate decision to force people to turn off tracking protection.
I saw a recommendation to use Firefox’s container extension https://support.mozilla.org/en-US/kb/containers, but it’s disabled in private browsing windows, and I always use private browsing windows.
The only reason I was on Twitter was because I follow some famous people, politicians that I like and some interesting people. I have no following (except for those onlyfans bots) so maybe if the people we follow gets rid of Twitter then we have nothing to go there for.
I left Twitter just after musk bought it.
