Why did you remove my Google Email and passwords? Fire fox lost my passwords Google email and other stuff. I may have 1000 or more emails that I can not read!!!!!!!

I opened firefox this morning on my laptop and it froze and shut down. When I opened firefox again it opened as a new window and all of my tabs and tab groups were gone. They do not show up in my history or recently closed tabs. Previous session is shown as current session so no option to restore.

Is there any other way to get these back?

im trying to restore a session that i accidentally closed. i deleted the sessionstore.jsonlz4 file, copied and pasted the upgrade.jsonlz4-20260715202819 file, and renamed it to sessionstore.jsonlz4. In the new window, all the tabs that were supposed to be restored have been replaced with moz-safe-about:blank tabs. The tab group where i had several tabs is still there on the tab bar. What did i do wrong?

I have two issues: One is figuring out how to remove what FF is storing on my device (an android phone). Clearing the cache does not do it. When I go to the menu, then privacy and security, which on my device is a title of a section, there is no cookie removal option. It is cookies and site data which is kind of annoying. I don't want ALL cookies deleted. I don't want signed out of all sites. I just want the 700 some odd MB's that FF is storing on my device gone. I would like to see what is being stored, and delete what is not necessary or useful. Does anyone know how to do that?

My second issue is that each time I update ff, all of my extensions, bookmarks and passwords disappear and I would like that to stop happening. I would like to know how to recover them. It is time consuming and frustrating to have to redo all of that each time I update ff, and some of it inevitably gets lost.

Thank you for any useful suggestions.

Hello all, i have a bit off an off one. I had a usb keyboard plugged into my laptop and and it had something sitting on it, I forgot it was there. I was using the laptop normal, and usually i use the CTRL and wheel on my usb mouse to zoom. But because of whatever buttons where pressed.. IT DELETED TABS(quite a few!)more thank the recent closed tabs could handle... i tired to do the session restore thing but im not super tech savy and messed that up.. But i do still have a copy of the json file thingy, but the backup thing got over written.. can i still recover with the one copy. The instructions are not the easiest to understand. Please help, i dont research and its been hard gathering that information. Thanks and if you need any more info just let me know!

This started since Firefox 153.0 (Debian package).

When I open Firefox for the first time after a reboot, it opens my latest tab but all the other tabs on that window are lost, and they show as "ghost tabs" as seen in attached image.

No other issue, other windows are preserved properly when I Ctrl + Shift + N

I have tried restoring my bookmarks using these steps but it doesn't work. Specifically, when I try to select "Choose File" in Step 3 nothing happens. The option will highlight, but when I click on it no window to choose a file pops up. Is there any other way to restore bookmarks using a json backup?

After opening up Firefox to continue work in one of my Saved tab groups, I noticed the 153.0 Update window.

All my saved tab groups have been deleted and the tab group options have been replaced with the new Tab container system in the drop down menu. I even made a new group to test and it saved and was accessible but all the important ones are gone. Nothing in the Json files, tried most of the solutions I've read online. none of these work.

Saved Tab groups don't to sync across devices and are local, so surely they should be saved locally on the system.

About one to 3 weeks after I switched from windows, Fire fox changed my browser, and I lost all of my data. I hate my new browser, I am so mad That I reported this to the FCC. I already view all Info. nothing helped.

Per Updates critically important open tabs were no longer accessible following the Updates in question. I need to recover the missing activity-chronic or request that the unfinished activity up to the point of Update be retrieved.
