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 !

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?

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.

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?

I tried linking my unlinked profile to my email, I made a typographical error there and when I tried to undo it, Mozilla says this profile is already linked to that email. Mind you, I have not even entered a password or verified that email address yet. I cannot even remove that email from the profile now, even if I do and try to re-sign, the accounts page says I am already synced to the typo email.

I just opened Firefox on my Win 11 pc, and find all my tabs have gone. The setting to reopen last session is active, as before. I think FF updated itself earlier today. I also had occasion to look at it briefly on my synchronised android phone. I would like to: - get my tabs back - find a way to stop this haappening (it's not the first time).

Any advice much appreciated, thanks. Richard

If I use extension 'Block Site' (shows up as a stop-sign shaped icon with a 'W' on it) to block a site, when I try to unblock it, it fails, with the below message:

"This operation cannot be performed in incognito mode. Please open the page in a regular browsing window and try again."

I am just clicking on the (whichever) site, from a search - not opening a private window... This extension used to work fine.

I did install DuckDuckGo browser, but removed it, as it was more trouble than it was worth. I would have to reboot my PC after each use before FireFox would connect.

A few weeks I started having trouble accessing the aa.com website. I would get this message:

Access Denied You don't have permission to access "http://www.aa.com/" on this server.

Reference #18.8b0ec617.1769870573.b9fa42c

https://errors.edgesuite.net/18.8b0ec617.1769870573.b9fa42c

I can access without issue on Edge and Chrome, but they aren't my preferred browsers. And if I use google to directly go to a specific page within the site, such a the technical support page, I can access that, and log in from there.

I tried all of the typical trouble shooting steps, like clearing cache and cookies. None of that helped.

Then today I decided to pull out my laptop and see if I could access aa.com from there. I could, with no issues.

So, this is somehow related to Firefox, but deeper than just the browser itself. But I'm at a loss as what to check next to correct this isue.

Not sure if it's related, but the automated guesses this page makes about my browser and operating system stated that I'm on Windows 10. This computer uses Windows 11, and it came installed with Windows 11.

My firefox is not recalling the history as I move through tabs. It doesn't appear in the sidebar or in the documented history. This only has happened recently, and it's still recognizing my bookmarks. I've done some troubleshooting, tried relaunching in the mode while switching through tabs, but it's still not recalling. Any help is appreciated.

No audio on Firefox. Google Chrome has sound. Settings at normal audio volumes. Tried computer shut off and re-boot. Tried reload of Firebox.but that didn't help. Had scam attempt just before no audio issue...not sure if that problem.

I can't open FIrefox. When I try to open it I get the following error message. "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." I opened Task Manager and could not find any instance of Firefox or Mozilla running. I uninstalled Firefox and deleted all the files and folders having to do with Mozilla and Firefox. Then I reinstalled Firefox. I continue to get the same error message. I am running Windows 11 64bit on a Dell laptop. Any suggestions? Ray

I posted a question in here two days ago because my firefox wouldnt open anymore i got a follow up answer telling me to give the crash id but never got a follow up after i sent it . i tried shuffling between profiles and in the end got it working but today my pc had a crash while firefox was open and it had to restart when i tried to open firefox its as if i just installed it and i dont have any backups to be honest i tried checking the appdata folder and there is a profile folder that seems big enough that it might be mine but it doesnt seem like firefox is reading it for some reason i tried switching the data in the profile folder that firefox is considering but it didnt work .

Is there some way to open all tabs on a synced device. I have the list of tabs showing in the sidebar. However, the instruction: "While viewing synced tabs in Sidebar, right clicking on device name allows you to open all tabs from a device at once." does not work. Right clicking does nothing. Version 147.0.2 (64-bit) in Windows 11. Thank you.
