New computer (Windows 11) shows 'Old Firefox Data'. Opened hidden files. Using File Explorer found Profile Folder & renamed it 'old'. Copied and pasted 'Old Firefox Data' as new profile. Firefox would not open. Had to remove etc and Firefox worked again. Thought this maybe the easiest way to get my Bookmarks back.

PS Presume Profile Folder does not contain Thunderbird Addresses?

I use chrome for personal use on my Macbook for all personal stuff. I use Chome on "this" windows PC for all my work stuff.

I would like to use firefox on "this" pc for all my personal stuff, and keep using chome for my work stuff to keep everything totally separate.

What's the best way to import all my personal login stuff from chrome on another computer to mozilla on this computer? Thank you!

I use Linux, but know nothing about it. My brother installed Mint on my desktop; he was my Computer Guru, but he has passed away. I need to update from FF88 to at least 99. Can you help me, please? Many thanks if you can.

Why has this started up again? Pdf files are automatically downloading to my computer when all I want to do is look at the file. So many files that now need to be trashed after looking at them. This problem has happened in the past, but was resolved, only now I am finding it happen again. I do not want to have files saved unless I want to save them, not Firefox deciding that any file I open should be saved. I have Windows 11 & Firefox Version 113.0.1. Is there a way to revert to an older version of Firefox?

Hello,

I have an active Pocket subscription for more than 8 years now. I wanted to migrate it to use Firefox accounts. However, by mistake I created a new firefox account using the signup journey - and I used a different email for this. When I logged into my Pocket account, it asked me to update and I did. I said I'd want to login to my Firefox account using my new account - so typed in my new email address and signin. It was actually prompting me to just enter password and continue using my old account - but I declined and changed the email to login to my new account. I was hoping both these would be merged. But they didnt' and after a bit of to and fro, I changed my new Firefox accounts email to the one that I'm already using for my Pocket account and did the same signup journey. They are merged now but I've got no data in my pocket - it's like a new account.

Please can someone help?

Thanks.

Hello,

I am wondering what if anything regarding settings, customization, data, etc is likely to break if I perform this update? THis has happened in the past and is why I turned auto update off. Should any intermediate updates be done to stepover/convert any of the data structures to a newer format?

Thanks, Steve

I want the version (which i assume is the ESR one) OFF my computer. I have downloaded a "regular version" (116.0.3) and have followed all instructions I have found on this site. It gets to a point and says it can't find the file. There is no README or Install file in the download so I am stuck. Please help me because I want the ESR version GONE!!! Thanks for any help! R

Since I agreed to a Foxfire upgrade ~5-11-23, I can't open Foxfire. I get this message "Error: Platform Version 113.0 is not compatible with minVersion >= 113.0.1 or maxVersion <=113.0.1".

Please help, I have a lot stored on Foxfire.

After downloading latest version of Firefox my bookmarks where deleted, so I restored my laptop back to an earlier date and now just Dismiss it when it says an update is available. How will I know when this problem has been taken care of where I can update Firefox? Firefox is the only browser I have as I've did everything to block Microsoft from taking over my laptop. I'm fixing to delete my old Microsoft account to complete that procedure. I'd have to research Chrome to see if they attempt to control what I can do with my laptop like Microsoft does. My only problem with Firefox was they allowed Microsoft to do it's best to change my system to Edge, but I'm still fighting them.

Just noticed at bottom of this page under Troubleshooting information,

 "securitySoftware": {
   "registeredAntiVirus": "Microsoft Defender Antivirus"

Now I see I still have connections to Microsoft. Thank you Mozilla for showing me this. I've got to change my security for this. Hope Firefox has it's on.

I was watching MSNBC on livenewsmag.com as usual and when I had to refresh, a Firefox screen said I had to update my browser in order to view content. An installer downloaded with a warning -- why is Firefox giving me a warning about its own file. And why is this happening with almost no further explanation of what to do.

Greetings everyone,

I accidentally double clicked on "Downloads" after accessing the "Tools" menu so all of my downloads in the "Downloads list" is now gone... :(

I know that the actual files aren't deleted but I can no longer see the location of the files I've recently downloaded :( :(

Thank you for any help!

I downloaded a Windows 10 update last night. It was Security Intelligence Update for Microsoft Defender Antivirus - KB2267202 (Version 1.361.793.0). Now, I cannot open Firefox. When I click on Firefox for around half a second I see an error box that says "Open Firefox in troubleshooting mode?" and nothing else, with no option to click yes, then the box closes. The same thing happens when I try to run firefox.exe -p to change profiles. I also cannot open Tor Browser, and I am wondering if there is a connection. I have tried uninstalling Firefox using the uninstall tool and reinstalling but I have the same issue. I uninstalled the windows update and opened Firefox. This time, it had the "Open Firefox in troubleshooting mode?" box but I could actually click on the yes option, and Firefox opened. However, when I clicked on the option to get a fresh install and remove the extensions, Firefox closed and I am back to the same place of it not being able to open again.

How does one migrate Firefox bookmarks and passwords from an old computer to a new computer?

There are four computers involved in this shuffle. Two new, one being retired, and one being repurposed. The only thing we haven't been able to figure out, is how to migrate Firefox's information from one computer to another one.

And, we've been working on this since Christmas. Edge, Brave, and Chrome took minutes. Combined.

But, transferring the information on Firefox has been impossible. Yes, I've read the help topics. No, they were not helpful. Firefox will not accept either the backup or export files from the old Firefox across multiple computers.

Yes, I have Sync. And, no, that hasn't worked either.

So, what is the next step?

I have been using Firefox 56.0.2 on Windows 7 for years safely. Until yesterday. We had one of those mini powerouts, that caused problems.

My hard drive is failing and Firefox will no longer fully load, it tries bless it, but some FF files must be in the damaged sectors of the hard drive. It then locks the system. Using Chrome works fine. But some logins/passwords/bookmarks had to be changed very recently and are not stored in the chrome browser yet. I hate chrome so use FF as the main browser.

I'm thinking that if I can install a fresh copy of FF 56.0.2 in a separate folder, a separate 2nd copy of FF, and then copy yesterday mornings backed up FF profile (before the crash) I could at least copy over all the bookmarks etc to Chrome so I can have my logins etc back.

This mornings backup failed to backup some FF files, all others were fine. Firefox worked fine yesterday but failed to launch this morning.

Please help save my sanity. I know I have to move to W 10, but cannot on this computer.
