Firefox Community Forum

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 !

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?

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?

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

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 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

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

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.

We hate this useless so-called feature and you've completely failed to give us an OFF switch! It's been many months with countless complaints and still no OFF switch! We've had this conversation before, all of your ideas must come with an OFF switch, especially so for the dumb ones like tab pinning! You don't ever force this dumb crap on us, ever!

Where is the fkin OFF switch already!?!?!?

I just bought a new computer. How do I sync firefox on my old computer with firefox on my new computer. The same for thunderbird mail. Please help. I am not a computer genius. Dave Muran [edited email and phone# from public community support forum)

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.

Is this the only way to send thunderbird an email??? If it is that's OK. I am a fairly new customer of Thunderbird. I have a new laptop and want to find out if Thunderbird has any questions forb me to answer. I think my password is OK, cause I signed in somehow. I am Blaine McKearney phone  : [removed from public] , email : [edited] @telus.net in Calgary, Alberta, Canada. Please send me an email if I have failed to open an account properly.
