As of 7/10/2025, Xfinity Streaming does not open through Firefox. I much prefer Firefox to any other browser so I am a little mystified as to why all of a sudden Xfinity Streaming does not open. I receive my Comcast email through FireFox but when it comes to streaming content, the Xfinity logo just sits there and does not open.

Since updating to version 135 all the tabs crash. I've uninstalled\reinstalled, deleted app data, disabled AV and created a new profile. The only time it works is in troubleshooting mode. I've looked at extensions and plugins and I'm only seeing OpenH264 video codec and Widevine content decryption. I've disabled those but still get the crashed tabs.

I'm also not generating any crash logs.

Dear Firefox Support Team,

I recently encountered a problem while using the ChatGPT platform (https://chat.openai.com) in Firefox. The issue was that I was unable to type anything into the input box ("Ask anything" field). The box would not respond to clicks or keystrokes, effectively preventing any interaction.

After switching to a different browser (e.g., Chrome), the problem disappeared, so it appears to be specific to Firefox.

Kindly look into this compatibility issue. I’m using the latest version of Firefox on [insert your operating system, e.g., Windows 10].

Thank you.

Best regards, James Tang

The new native tab group feature has an option to "Save and close group", implying that you can restore the group. But doing this, you will find that the group disappears.

Is this a known bug? Has anyone figured out how to restore a saved tab group?

It's not possible to switch Google accounts for Gemini in the AI Chatbot toolbar. When I select another Google account in the chatbox, the browser redirects to https://gemini.google.com, but the AI chatbot continues to use my default Gemini account, see the attached screenshot.

There was an update today on my PC laptop, I think from FireFox. After the restart, my bookmarks have all disappeared. The instructions to restore them are useless. I go through Menu/Bookmarks/Manage Bookmarks/Import and Backup/Restore/Choose File. THERE ARE NO FILES TO CHOOSE FROM. According to the instructions, there should be some dated entries. Nada.

I tried the Troubleshooting blahblah and that was equally useless.

I'm panicking that I've lost years of carefully organized bookmarks.

When i mouse wheel click the bookmark folder, it always switches to the first tab when doing so. This notably doesn't happen when i click the non-folder bookmark. Is there a way not to have this behavior ?

All my other browsers work fine but since April 4, 2025 Firefox won’t work at all. Websites won’t load. I have tried to clear my cache & cookies, I have checked my connection settings, I have checked for malware, I have turned off all my extensions and I have completely restarted my computer several times now, nothing has worked. I also did trouble shoot mode & reinstalled Firefox (though I will admit I maybe didn’t do this step properly). I refreshed Firefox. Why is it not working? What happened? I don’t know what to do as I don’t want to lose all my bookmarks and passwords that I have yet to move over to my password manager. Please help.
