Firefox Community Forum

I recently upgraded to Mac OS Tahoe 26.0.1 and opened Firefox as usual. None of my accounts are visible and when I try to follow instructions to go to settings and find my profile I cannot do that either. I cannot change the search location when the account settings window opens.

I thought to do an update but everytime I go there I get the message that Firefox is up to date.

Does anyone have a solution?

The recent update to Firefox 144 seems to have completely broken my profiles. Previously, I had an additional profile that I could access and manage very easily from the about:profiles page.

After the update, clicking on "Launch profile in new browser" brings me to a completely blank screen. I can type in the search bar but after pressing enter absolutely nothing happens. (attached image)

I still have the data down the root directory. I tried following the instructions in this post https://support.mozilla.org/en-US/questions/1513880 to transfer my data to a new profile created from the new profile manager, but despite copying all the files from my old profile into the new one, absolutely nothing changed.

Honestly I would rather have the browser from the about:profiles page working again, but if that's not possible how do I transfer my profile data to the new profile manager?

I'm on windows 11, but I don't know why Firefox's troubleshooting page thinks I'm on Windows 10, if that matters.
