Hello Mozilla Team,

I'll directly jump into - 12 years of Bookmarks and history are gone after the last update. No warning or anything. Can you help me restore? That's unbelievable.

I have been using Mozilla Firefox on my mobile phone or PC since 2015. So, after so long, I found the Gmail that I used to log in to Mozilla from 2015 to 2018. Now, if I log in with that Gmail, will the previous history or data be restored or will it be Mozilla's?

I lost all bookmarks on or about June 29, 2026 after doing a Firefox update that asked me to create a profile when I'd never had one before. I have not been able to recover them.

For some reason firefox uninstalled on my computer, I genuinely do not know why. When reinstalling it, I have an old save from my backup of that morning (I have it setup that way). However, I do not remember this password whatsoever and I am freaking out a little bit since I have information on there and I am just trying to get it restored onto my account.

Any help would be appreciated.

I have this icon on my Firefox logo pinned to my desktop and it has changed the entire look of my FF how can i reset it to what it was and get back all my bookmarks.

Can someone please help me

recently bought new desktop and upgraded win10 to win11 in the process (preloaded). I found 'places:sqlite' in win10 firefox and copied it to usb drive. How do I copy it to win11 firefox? i.e. where is the folder containing the sqlite file in win11? will copying the file also place the bookmarks in the win10 firefox locations? Will the layout preferences transfer over (hate to be negative, but I hate the win11 firefox interface that was preloaded on the new win11 machine.) thanks for anyhelp.

it looks like mozillo ambushed me, did away with all of my setting I spent years getting where I wanted them and left a folder called Old firefox data on my desk top. how do I make it look and act like the old firefox? I do not want the side bar I want the icons on the same line as the search bar. I want firefox to be my default everything like it was. I hate edge but it seams the only way i could get rid of it was to uninsal firefox and reintal this new pink firefox home page. I want my home page to be foxnews. how do I restore everything from teh old data filke to this confusing new page?

I got a pop-up that said I needed to upgrade my Firefox so I clicked on (Firefox ESR-64Bit) and lost my one and only profile in Firefox. HELP I need it back it has all my passwords and bookmarks

I'm on Windows 11. After I added some plug-ins and extensions to replace the ones that went missing during your last update, my bookmarks also went missing. (They were there before I replaced the plug-ins and extensions.) I followed your instructions on how to access my bookmark back ups, and found them. However, everytime, I tried to install one of the backups, I ended up with no bookmarks at all in Firefox.

Please help, I have no access to any of my accounts!

Thanks,

Charlotte

bold text'I am so fed up with these updates loosing my passwords and data, why ? All my settings are messed up and last time it took two weeks to get everything back, why? I give up total idiots for releasing updates that are sub par!

Almost every time there is an update------it screws up something I rely on. In this case, the sites I have saved under the top search bar have now disappeared. Why?????? And how do I get them back.

I readily admit that I am technically challenged and need clear concise instructions step by step to find them and put them back where I had them. 

Why oh why do the buggers making these changes think anyone is going to like them. Leave things that work well ALONE.

You forced an update and all my open tabs vanished into thin air. I was working with those!!!

I tried to follow the history recover path, no-go. I tried the json file path and can't get Firefox to open the tabs in the json recovery file from a month ago, not that that would be helpful anyway since I want yesterday's before the update!

Now I gotta spend a lot of time finding those scientific papers again - should charge you my hourly rate for wasting my time.

It's sh.it programming that's what it is. Bet you they were using AI to do the update.

Well never mind, I've grown tired of Firefox anyway since it just starts using 80% of my RAM when I have more than 10 tabs open. There's other browsers.

There was an update and I thought I had to create a profile but no. So now I have lost all my very important bookmarks and I do not seems to be able to retrieve them. Only one date top retrieve which is only yesterday

Firefox unable restore session when switching profiles and instead opening apps installed on the profile I'm switching to.

I have installed Whatsapp web (web.whatsapp.com) on "Profile 1" as a Windows app.

I have some tabs open in "Profile 1" and I switch to "Profile 2" and close the "Profile 1" window with "X" button of Windows 11 but keep the Whatsapp window open.

When I open the "Profile 1" from profile menu, my expectation is that, those previous tabs should be restored, but firefox is opening the Whatsapp web app/window.

I just got a samsung galaxy s26 (old phone is not available); when i accessed my Firefox, my Collections were missing. From other research, it seems that Collections are not available anymore. However, there must be some way to recover the websites that were stored within them, so i can at least rebuild them.
