During cleaning up by CCleaner, accidentally the Histrory of the Firefox Browser (open folders and apps) all were deleted. Is there a way to retrieve and restore the then open folders ?

Hello Mozilla Team,

After the last update - all my 12 years of data is gone? No bookmarks or anything? No warning to do a backup? That's ridiculous guys. The only option you provided me with is 32 character recovery key I set up in 2022? Well I dont have it. Can't recover it. And if you don't intend to assist in some way - it's Game Over Firefox for me!

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.

Good morning,

I just made your suggested "reorganisation" of the Firefox Browser with the result that all my hard collation of all my bookmarks, website and passwords are presently gone!!! I can only hope that you have a possibility to recover my datas.

Please advise your instruction to recover my websites, bookmarks etc.

Many thanks in advance.

I removed the solid-state SSD drive from my physically-broken Windows 10 HP laptop and connected it to my new Windows 11 HP laptop using an external adapter, wanting to move the contents to my new machine. But already I find that only about 3/4 of my bookmarked browsing favorite sites and document files are among the items that I can find on the old, externally-connected "D" drive (D:>USER>OWNER>FAVORITES). I tried visiting some of the bookmarked sites and hitting "bookmark this page" for each, but then none showed up on my new Windows 11 machine's firefox browser bookmarks sidebar. Perhaps they are being put elsewhere because I am opening these sites from my old drive??

I probably need to first understand if and how much that the two drives are still operating separately, so not cooperating with each other in the way I had hoped. I know next to nothing about any of these things but have used the Firefox browser and documents files for many years without too many issues.

I realize there have been several questions on this topic, even with the same subject heading.

The popup generally appears if you're trying to exit or refresh a page but haven't hit post or submit after entering data into a field. It's a good warning in case you've forgotten to do just that. I accidentally restarted Firefox after an update, and when I returned to the site I was working on I got this popup. Which makes sense, because I had entered in a ton of data and hadn't submitted it.

However, the page that I was returned to wasn't the one into which I'd entered my data - it was more of a home page for the website. I suspect this is a lost cause, but ... is it at all possible that the browser actually has that data saved somewhere and is waiting for me to complete submitting it? Or is this just a false positive?

i had two different firefox browsers yesterday. I deleted one but all my passwords are gone from the other browser. When the firefox browser got uninstalled it created a backup on my desktop called bookmarksback up. how can i move that file into this new firefox and how can I retrieve those passwords?

Today, after the last update of the software, I lost ALL my tabs (2 years of materials) and there was no way to recover them. Furthermore, I had to spend hours to retrieve at least the most important tabs I use for work.

This is not acceptable, please fix this issue and make the recovery of tabs possible and easy.

I lost all of my bookmarks and saved passwords with the latest update. How can I revert back to my old version so I can at least save them to a file to be imported?

Lost all tabs during an update including(weirdly) all theme stuff. Its not in the restore in history. But the themes part is the one that is strange, because why would themes change during an update, all while all my tabs are lost?

I had my computer fixed due to a virus and now I can't get my old firefox with all my saved passwords back. How can I get it back. I'm using my same email address.
