When opening Firefox version 147 it asked if I wanted to install updates and after answering affirmative, then it gave "Error: Platform version '147.03' is not compatible with minversion >=147.02 maxversion <=147.02. Maybe try to reinstall Firefox?" The browser will not open. What is the workaround??

Please return my Computer to using Firefox default as my browser as it was 2/01 /2026.Ive tried several times to do this w/o success . I was using windows 11 and have been trying to get rid of MS365 which I never used but have been charged for a solution , but have been blocked and refused cancellation after they asked me to change my email address and PW . Insanely confusing !

Good morning. I opened up Firefox this morning and all 4 rows of shortcuts were missing. I have gone into settings and made sure the settings for 4 rows was still the same. I cannot find them anywhere. Please help

After the last system update, I now am being asked to enter my "Primary password", every time I open a new page. When I try entering a password , it is not recognized and I have to click on cancel in order to proceed. I have used what I recall was my password but it is recognized, but I don't get a message telling me it is the wrong password. How can I get back to the previous version that did not ask for my Password. Is that an option?

Hello, Having followed the advice as under: If you've previously made use of Firefox Sync, please make sure you're signed into your Mozilla account and have enabled Bookmarks within your Sync settings, because Firefox will automatically download any available data from our sync servers as long as you are logged into the account you used to sync.

Additionally, please consider that if your bookmarks are still available in the local storage of another device, signing into Sync on these devices will let you upload this account data and make your data accessible on any other devices you enable Sync on.

Andd checking the the Bookmarks tick-box was checked [as was last attempt] I tried to sign in to open the required page, but got 2 x 'error' windows, as attached, one for enail address [been using this for 2 yaers] and the other for password [how did I get this page up with the wrong password??]

I'm obviously a very dim Brit . . . . . please would you advise me as clearly as possible about whatv the heck is going wrong, thanx Kr CB

Before the new profiles update in Firefox I was using the old version of creating profiles and I want to move that profile into the new profile method. Is that possible?

Since a while, I think it is since I created an extra testprofile with "firefox-esr -P", but I've set my main profile as default again

When opening a link in another program than firefox I get always: a popup "Close Firefox" "Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile."

I do have both firefox and firefox esr, I usually use regular firefox the second came with the debian 13 repository.

I keep the esr to test display issues for reproducibility on my personal desktop, because I manage debian 13 kiosk-style desktops with firefox-esr.

(I noticed also that the regular firefox profiles can not be opened in firefox esr, so I use an extra profile for esr)

I searched how to disable any random new AI features Firefox was about to cram into the browser.

I was served this support page that says I can "Block new and current AI features (single switch)"

Simply, the described feature to disable AI features isn't in the settings. I've look and tried searching for "Block AI enhancements" & "AI controls" but no luck.

Please tell me they haven't given the writing of support pages to some shitty LLM.

Hi

I have tried multiple times today to change my password to a more secure one.

I do not receive the emails with the code to continue - have checked junk, spam etc.

I have another email address you can use: [email 2 removed] or [email 3 removed] Please help

Error message: the bookmarks and history system will no be functional because one of Firefox's files is in use by another application. Some security software can cause this problem.

I tried following the directions in "learn more" but to no avail. Please help this senior citizen get his bookmarks back! Thank you.

Hello! I accidentally logged into my account after switching to a new computer, creating a new recovery key. Now i do not have access to all my saved passwords. I have my recovery key but cannot find where should I type it to get back all my information. Is it possible to recover my information using the original recovery key, not the one I accidentally created? I really need to get the access to all my saved passwords, please help me with it. Thank you!

I have two e mails, but when i try to go to my secondary email [email 1 removed]@gmail.com i always get my primary one, [email 2 removed]@gmail.com. why?

When I access the website of UGC ( https://www.ugc.fr/ ) the access page opens up but immediately freezes: the screen luminosity decreases and the pointer cease to function: I cannot acces any of the options: select movies on show, select cinema programmes or schedule, open my UGC account to reserve performances ... Nothing works ... I have tried to reduceprotecton, etc as sugested on Forum and other suggestions: nothing works. I have no problem at all when I open the same website with Opera or with Microsoft Edge ... Why it does not work under Firefox puzzles me. Can you do something about it ? I use Firefox as my defaut internet access without problems for everything else ! This is really strange and most annoying. Thanks for your help.

My profile images have weird graphical issues behind the profile images. I don't find anyone else mentioning this but I am sure I am not the only one. What can I do to fix this, it is very annoying.
