Dear all,

Just updated to Firefox 147.0 (64 bit) today and the ChatGPT website is not working anymore. Dead buttons, cannot login, cannot even send prompts anymore. UI loads but JS does not initialize. Buttons inactive, input disabled. Help!

Hello

Is it this subject https://support.mozilla.org/en-US/forums/contributors/717521#post-89944

You can try
1 - Go to configuration editor https://support.mozilla.org/en-US/kb/about-config-editor-firefox
2 - Enter a search term network.http.dictionaries.enable
You can double-click on the preference to set the value to false

I had the same issue on Version 147.0 (64-bit) for Ubuntu.
I've changed network.http.dictionaries.enable in config editor to 'false' and it worked.
Thank you!

I have Windows 11 with Firefox 147.0: Same issue as above. Set network.http.dictionaries.enable to "false" and it works again.
I'm also using Linux Lite (ubuntu based) on a VM on the same machine on same network with Firefox 147.0 no issue at all.
