⚠️❗~ Multiple Versions of Firefox Affected By Same Bug (Standard/Developer/ESR) (UPDATED: 11/26/24) (133.0 WORKS; OTHER VERSIONS STILL BUGGED)

This has been posted a few times, but I thought I would condense the information. After installation and upon visiting any x.com URL, the addon prompts you with a popup (the only option is "OK"):

There was an error in initializing security header generator: Error: Failed to fetch homepage: TypeError: Window.fetch: https:/// is not a valid URL. User Agent: Mozilla/5.0 (Windows NT 6.3 to 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/115.0 OldTwitter doesn't allow unsigned requests anymore for your account security. Currently the main reason for this happening is social network tracker protection blocking the script. Try disabling such settings in your browser and extensions that do that and refresh the page. This can also happen if you're not logged in.

Myself and others have noted that disabling addons & relogging has no effect. This bug essentially renders the website inoperable. Seems pretty urgent to me.

Works fine with Firefox 133.0

Okay, I edited title so not misleading. Any information regarding other versions' bugs? Is it something they (X) changed? Was working fine up until very recently.

Opera GX is getting this error, and IDK how to fix it. Am I unable to use Twitter on Opera GX now?

I also have the same problem too! I don't know how to fix though.
