Firefox Community Forum

Hi folks -

I've just seen the update that firefox now allows "profiles" for different purposes (e.g. work, fun, etc.) which seems really handy. But I'm trying to wrap my head around how to approach restructuring my current setup. In particular, do these profiles *all* sync with my mozilla account? Or do I need a separate mozilla account for each profile? (if so, that sort of defeats some of the utlity here unless you're sharing the PC).

I can't tell from the support article, doesn't seem to address this, but you do need to login again if you set up a new profile.

Thanks, Patrick

Is there a way for me to opt out of any new "AI" functionality/features that would otherwise be enabled by default? Like the tab suggestions and perplexity in search. Having AI shoved down my throat from every corner of the internet is kind of frustrating.

SUBJECT: Profile missing after update to 146.0.1 

After the last Firefox update (146.0.1), I can no longer access my profile that included bookmarks, history and passwords.  

After the update was done on 12/19/25, I was given the option to choose between my original profile and a newly created one. The next day when I opened Firefox, there was only one profile shown and my original profile was gone. I have read numerous fixes for this problem but nothing seems to work.

I have done the following to try to locate my missing profile to no avail. 1. I went to the Profile Manager but the only profile listed was the newly created one. 2. I didn't do a refresh so there was no "Old Firefox Data" folder to copy the data from. 3. Used about:Profiles, Again only the newly created profile was listed 4. I used ~Library/Application Support/Firefox/Profiles. Still no luck. 

Could my profile have been moved to another place or could it be hidden? Any help would be greatly appreciated!

I want to know how to stop auto-fill on any form and also prevent drop-down menus keeping email addresses or anything else, like passwords. I hate drop-down menus with info on them and , also, doing auto-fill.

Please offer suggestions. I have not had success researching on my own.

Thank you,

To sign into Chatgbt I used my google account. Mozilla asks me "do I want to store info in persistent storage?" I click "learn more" about persistent storage. It takes me to a page that has zero mention of the words "persistent storage". That is a huge UX error. It says to me that really, you don't want me to know about persistent storage, and prefer that I remain confused and feel forced to agree to things I may not really want to, because you're making it difficult to understand what's actually involved. Not cool. Definitely now considering changing my browser after over 20 years.

I just updated my browser less than a week ago. Today I got another notification for yet another update. This logs me out of everything.

WHY so many and so frequent are firefox browser updates. I am about to stop using this brower if it continues. It's very disruptive!

Thank you for your attention to this.

When attempting to sign in to my social security account I get the following message: Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.
