Hi all,

Firefox 140.10.2esr Windows 11

Opened Firefox this morning and it said I was using an old version of Firefox and it couldn't load my profile. I have always used the esr version.

I had a look at the compatibility.ini file under my profile and it had version 150.xx. Is that a bug with the last update?

To recover I backed up my profile then changed the compatibility version to the version of Firefox I am using. I was able to load my profile and while all my bookmarks and settings are there, my saved credentials are not. The key4.db and logins.json file are both still under my profile folder, they just don't seem to be recognised; no errors. Viewing the logins.json shows my encrypted credentials.

Does anyone know what is going on and how to resolve?

thanks

Den Aktivierungscode für Firefox zu erhalten dauert immer 30 bis 40 Minuten und hat aber nur fünf Minuten Zeit den einzugeben! Ich habe es jetzt dreimal versucht und es funktioniert nie, bitte um Lösung

Cannot create account. Just started using Mozilla because my ISP does not like Macs.

Apparently Mozilla does not like Macs either. I entered the information and just got "Bad request (400)"

I've been floundering and cannot find any help.

Earlier I logged in to Firefox to pose a question. Checking email, I had a notice from Mozilla that my account was used to sign in: Firefox on Windows 10 / United States (estimated) / Thursday, Oct 23, 2025.

Does Firefox think I'm using Win 10??? I checked my computer and it verifies that I am running Win 11 with all updates.

Call me confused. Or is this a non-issue? I ask because I'm trying to get into a member website and after I login, it takes me to a page that is for new signers ... not an existing member. Has happened several times.

Thanks,

Ron

Hi, Win 10 Pro new installation. Dell Optiplex MBR type Bios.

I had saved a recent profile to an external drive in its own name (i.e. not the profiles folder)

After the new Win 10 installation, I downloaded a new copy of Thunderbird.

I then copied the saved profile into the new Profiles folder, selected it in Choose user profile and started Thunderbird.

Thunderbird opened but not with the saved (8+ Gb) profile, just one new email account and asking for passwords to other email accounts I used before, and no folders.

I went back into the profiles folder and renamed all other profiles "OLDxxx999, but still the same one new email account when I opened Thunderbird.

I desperately need the saved email folders - I don't mind loading all the email accounts again, just need my court case history folders.

How can I force Thunderbird to use the saved profile, or can I identify and individually load in the saved local folders?

Thank you for any guidance towards a solution.
