Hi.

Just a quick note to mention that the problems earlier today with viewing X/Twitter in Firefox do now appear to be resolved.

If you turned it off or down earlier, feel free to turn Enhance Tracking Protection back up to Strict if you prefer the web that way.

thank you for your fast reply despite my being so cranky. unfortunately, i'm still blocked even with protection disabled for x.com. i've restarted the browser as well as the laptop, but still blocked.

You can try these steps in case of issues with webpages:

You can reload webpage(s) and bypass the cache to refresh possibly outdated or corrupted files.

• hold down the Shift key and left-click the Reload button
• press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
• press "Command + Shift + R" (Mac)

Clear the Cache and remove the Cookies for websites that cause problems via the "3-bar" Firefox menu button (Settings), click the padlock icon (Clear cookies and site data) for the domain in the selected tab.

"Remove the Cookies" for websites that cause problems:

• Settings -> Privacy & Security
  Cookies and Site Data: "Manage Data"

"Clear the Cache":

• Settings -> Privacy & Security
  Cookies and Site Data -> Clear Data -> [X] Cached Web Content -> Clear

• https://support.mozilla.org/en-US/kb/how-clear-firefox-cache

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.

• switch to the Default System theme: "3-bar" menu button or Tools -> Add-ons -> Themes
• do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window

You can check for issues with Enhanced Tracking Protection. Firefox shows a purple shield instead of a gray shield at the left end of the location/address bar in case Enhanced Tracking Protection is blocking content.

• click the shield icon for more detail and possibly disable the protection

You can check the Web Console for relevant-looking messages like blocked content.

i had to go to open in troubleshoot mode to get it to work, however, that completely wrecked how i had firefox set up for myself. wiped out all extensions. lost the tabs i have open each time i open firefox. lost the sessions i had on those tabs. thanks for making this problem take hours to resolve and get back to my normal browsing.

this rollout of your tracking feature is a sad sad sad reflection on mozilla. it shouldn't have come to this.

Same issue. Its awful.

If I reboot, then I have to go back into trouble shoot mode. For someone dedicated to this browser over a decade, this sucks

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock Plus, NoScript, DuckDuckGo PE, Disconnect, Ghostery, Privacy Badger, uBlock Origin), always make sure such extensions do not block content.

• make sure your extensions and filters are updated to the latest version

I cannot access Twitter/X at all now using Firefox 126.0.1 (64-bit). I have tried all privacy settings (Standard, Strict, Custom), used Custom with everything disabled, added twitter.com and x.com to the exceptions, clear cookies and cached data, closed the browser, disabled ad blocker, etc.

This is ridiculous!

Can you access a direct link to a user page such as

https://x.com/mozilla

(That loads for me with full tracking protection applied, signed out. Have not tested signed in recently.)

If you don't get to the page, what leads does Firefox give you? For example, does the site display an error message, or does Firefox display an error message, or does it time out, etc.

Note: Older links to Twitter URLs get redirected to X URLs, so you might need to update your bookmarks if that redirect is failing.
