I just installed Firefox Nightly 153.0a1 on my Mac running Tahoe 26.5. I did disable all AI features in Settings. Unlike Firefox 151,0.1, there is no VPN icon. I also enabled the Nova settings in about:config.

I have used the new and old profile system, and I use Firefox Nightly. On one of my profiles I am unable to delete profiles created with the new profile system.

When I use Manage profiles and click the delete icon I get about:deleteprofile but clicking the Delete button nothing happens. The display doesn't change, no message appears in the browser console, and the profile doesn't get deleted.

This is running Firefox Nightly 153.0a1. When I use Firefox 151 on the same system (different profile) the delete works fine. When I use the same version of Firefox Nightly on a different system about:deleteprofile works fine.

Both computers are running Ubuntu 24.04.4 LTS. The new profiles don't show up in about:profiles. I now have several profiles I can't delete following the instructions from https://support.mozilla.org/en-US/kb/profile-management#w_delete-a-profile . Most of them I created, closed the window, and immediately tried to delete.

Following the instructions from https://support.mozilla.org/en-US/questions/1572980 and https://bugzilla.mozilla.org/show_bug.cgi?id=2000125#c4 I looked at the toolkit.profiles.storeID preference. The preference is the same in the child profiles as in the original profile.

I tried starting the original profile in Troubleshoot Mode. That had no effect on the behavior.

i have been using firefox for like an year, found out now that the email i used for my account on my browser is wrong, the domain has a typo. Does it mean that now all my passwords are saved on a firefox account i cant even access (i have to still finish the setup, obviously i cant as i cant get a code in an email that doesnt exist) and that i cant remove it, ever? Does firefox sync up stuff on an account without the setup even being done yet? Or is the stuff just saved locally and im good with removing the account?

Before reinstalling Windows, I made a backup, but since I didn't update the system until a day later due to work, I forgot the backup password. I've tried every password I could think of, and I don't know what to do now.

nach dem start von firefox erscheint ein völlig neues profil - alle vorher gespreicherten tabs sind verschwunden. gibt es eine erklärung oder hilfe, um die vorherige ansicht wieder herzustellen?

May 2026 Firefox app update has been a disaster for me. Nothing loads, and many log ins, like microsoft or facebook no longer possible. Too many new features take too much data and just never load anymore. Eventhough I set it to delete history on exit, because it saves long lists of history anyway, slowing or stopping all. Password manager suddenly has bern giving the wrong passwords, (suggested ones instead of my registered ones?), so I got logged out of my microsoft and meta accounts on all devices. Does anyone know why? I would appreciate all ideas and remedies. Thank you, cb

this month I started having issues logging in to my pharmacy and my bank using firefox on my desktop computer. I get stuck in a Scanning By Zero Phishing loop. Ultimately I am forced to use Microsoft Edge to access these 2 accounts. My bank actually apologized for interrupting my login saying something about my login made the bank think I am a bot.

Oddly enough I have 2 laptops, mine and my sister's, that do not have this issue.

Obviously I have identified my desktop computer as the problem but I have no clue how to fix it.

Steps I have taken so far: clearing browser cache and logging into windows safe mode and clearing the temp and prefetch folders. I have had intermittent login issues in the past and these steps USED TO WORK but not anymore.

Just in the last week, possibly since a software update, when I click on a link I am diverted to a new website that I did not want to see. The link I clicked also opens, but I have to close the unwanted tab and navigate back to the one I wanted. How can I stop this from happening?

all the routes off the icon lead to "installation and download links" have done both actions with the same result of red dot and NO access to the free vpn...frustration is gaining steam! I have found the button to turn vpn on and off but even closing the browser after closing nor leaving it on has helped activate the service!!!

Please help, old but not too ignorant!!
