Hello,

When FF on my Windows 10 machine crashed FF asked if I wanted to refresh FF. I said yes, and FF reopened as usual with all my tabs. After I closed and reopened FF the next time, it reopened without any of my tabs. I then discovered that FF had unchecked the “Startup Open previous windows and tabs” box, which I had previously religiously monitored to be sure it was checked. So I lost all my previous tabs.

In my sessionstore-backups folder I found the file upgrade.jsonlz4-20 as last in a list of three more recent file names. I then dropped the file upgrade.jsonlz4-20 in the scrounger tool on this site: https://www.jeffersonscher.com/ffu/scrounger.html. It expanded in the big window, and when I clicked on Save uncompressed JSON as text, I see all the URLs run together in a text file.

How can I use this information to recover my tabs, please? If so, how? Or is there a better way to use the Scrounger – or another – tool?

Otherwise if I delete the three more recent file names in the list above the upgrade.jsonlz4-20 file, and restart FF will I recover the missing tabs? If so would I the check or uncheck the Startup Open previous windows and tabs box?

Lastly, can I restore my missing tabs using Windows’ “System restore” tool from 3 days before the crash?

Many thanks for any help!

I recently upgraded to Windows 11. I use Firefox as my primary browser, however sometimes I need to use the MS Edge browser. When I open MS Edge, it automatically closes Firefox and deletes my las set of Firfox tabs. How can get my Firefox tabs to remain? ...and yes I DO have the Startup setting box checked for: "Open previous windows and tabs"

its really annoying. Unlike Firefox desktop, Firefox mobile (using nightly for the about:config) suspends tabs instantly.

When I switch to another app and go back, often the tabs reload. Or when opening another tab, the old one is deactivated and reloads when opening again.

How can I change this behavior, set the amount of open tabs to be cached until I close the browser?

My browser just updated to version 100.0 and now there's a big white block at the top that blocks access to tabs and the Minimize/Maximize/Close buttons at the top.

I found a few other articles going back to 2015 with this same issue and the only solution that helped a tiny bit was checking or unchecking the Title Bar box. Unchecking it helps a little bit as you can see in the attached screenshot.

The top of the image is with the Title Bar box checked, the bottom of the image is with that box unchecked.

Any idea how to resolve this?

Why is there now no option to close present tab only when clicking on X. The old (default) warning was excellent. With no warning, clicking the X kills Firefox - and all open tabs. This has lost me hours of work already. i certainly don't want to go down the route of restoring all tabs first. I can't rely on it, for instance, holding all comments made on a form. And for that matter, I wouldn't want that to reinstate a login.

Please can we return to the warning with 2 options Close all tabs and Close current tab only.

This only happens on mobile. Whenever I leave the Firefox app (without closing) and reopen it, the website reloads and everything I had done beforehand is lost. This makes it impossible to use Firefox along with other apps at the same time. The same issue also occurs when I have to open another app (from Firefox) to upload a file; after selecting an image to upload, I'm back to Firefox, but the website reloads and forgets I was uploading something.

TLDR; websites reload upon leaving Firefox, without closing the application

How many tabs that is allowed to send to another device?

I'm trying to move my tabs from my laptop to my PC but it only send 105 tabs while I want to send all the 213 tabs. Even after sending the first 105 tabs, I'm unable to send anymore tabs.

Is there a way to send more than that?
