After restarting my pc, signed in on another windows account, which does not have Firefox installed. Then, signed in to my account, opened Firefox (Developer Edition 112.0b9 (64-bit)), however, all of the tabs, pinned tabs and history were gone. Can't restore from the menu, can't restore from the Profile folder, because files in it were overwritten when I signed in to my account (according to time modified). Anybody been in the same situation? Any advice? Thx

OS Version: NAME="Fedora Linux" VERSION="36 (Workstation Edition)" Firefox Version: Version 104.0.1 (64-bit) Mozilla Firefox for Fedora fedora - 1.0

Issue: I have "Ctrl+Tab cycles through tabs in recently used order" enabled. When I press(and hold) Ctrl+Tab I don't see the thumbnails of the tabs I'm cycling through.

When I create a new profile (on about:profiles) sometimes I get Thumbnails on Ctrl+Tab, sometimes not. Removing all Addons doesn't have an effect.

Does someone know how I could go about debugging this issue?

All my inactive tabs on Firefox iOS are unable to be opened, whenever I tap on them the page won’t load and I can’t even copy the url from the search bar since there’s nothing there, and half the time the app crashes too whenever I’m on one of the inactive tabs.

I also can’t use the hamburger menu to copy the link or send to another device, and though the tab thumbnail is saved in the cache the page itself refuses to load.

Is there a way to bring them back? I’m running the latest version of the app and iOS.

Many, many months ago I did mundane search and opened a webpage in a new tab, as per normal. Nothing particularly stood out about this search and when I was done, I closed the tab. I didn't do anything different. I didn't save a bookmark or change any settings. I just looked at the webpage and then closed it when I was done. (It was a web article on some random tech site, if that matters)

Anyway, now whenever I open up my Firefox browser there seems to be a random chance that this previously closed tab will open on loading. And when I say random chance, I'd say about 1 in 5 chance. It doesn't always happen.

Just to be clear: I do have the browser set to restore my previous sessions. This is a setting I want to have on. However, this tab was not part of my previous session as I specifically closed it - and continue to close it every time it opens itself. Also, my Homepage is set to default and nothing else.

Not only that, but there are two very peculiar details about this case that make it very, very strange: 1. When I originally opened (and closed) this tab, I was using normal Firefox. I have since switched to Firefox Nightly. All of my other tabs that I like to keep open had to be searched and loaded up manually, one by one, after I did the switch. This one tab, however, is just showing up on its own. 2. Opening Firefox on a separate devices (second desktop PC, laptop, android phone) will occasionally load up this tab.

I do have my browsers set to sync, which is what I'm assuming is why it's following me around. But I don't understand why nor how to stop this specific page from loading after I keep closing it time and time again. Plus, why aren't any of my old tabs from my old Firefox browser following this same behavior after moving to Nightly? - I've closed hundreds, if not thousands of tabs. Why is this one following me around?

Hello Guys,

I am having a bit of trouble here. First I have tabs that are popping up and they are ads or just a black screen. Some of the pop ups are on the page that I am looking at. How do I get them to stop? Also in my Firefox search bar it has changed from google to microsoft search engine but when I hit the search arrow it has a box that says- a browser seach and then goes to microsoft bing. Can you help me figure out how to get my mozilla back to normal. I love using this and dont want to let it go. Its the best browser ever!!!

I can have a youtube video on two tabs, but I cant play both of them. I want to do this because I want to play "1 hour of silence occasionally broken up by AUUGHHH" to jumpscare myself randomly while watching another youtube video because I am a masochist. Whenever I play a video on one tab and go to the other and play that one, the other one pauses. Please help me satisfy my masochistic desires. Thanks in advance :)

This new update, every tab is closed! Annoyed is an understatement. This has never happened before. Really really annoyed to the point of changing browsers after using this for years now.

Hi Everyone

My Question is if I create a new profile using the about:profiles page and switch to a new profile Will I keep the tabs in my old profile if I switch back to it? And will each profile keep it's own tabs I have many tabs open that I don't want to lose

Thanks!

Hi, yet again, I've opened Firefox to find just one tab, a Mozilla ad in this case; the 40 or so tabs I had open are gone. I had prepped for a day's work ahead and had opened the tabs I needed for research and work, ready to start in the morning. I don't know what's causing it; I do know that this most often happens when I've shut down Firefox, then go to Thunderbird for a last check of emails, and click on a link in an email which opens Firefox.

Is this a bug? Does Firefox just not like being opened via an email link? Is it a problem if a Firefox private window has been left open inadvertently, even though Firefox was properly shut? Or is it just Firefox updates that cause this problem? It's been happening for a while now, and is really frustrating and costly, workwise. Yes, I do have restore previous session ticked. I've shared the data report below - at the time of this post, not at the time of opening Firefox. Any help would be really appreciated, especially if it's simply explained :) Thank you

I had a crash and the file for about:profiles is not there. It lists a possibility but it says it cannot locate the file (duh). I have a lot of tabs and I need them back. I look in the file locations and other than what the blank profile it is setting up there is only one from about two months ago in local and nothing old in roaming. When I use space sniffer it shows a large file size for what it is using for the current empty default file. It seems like the tabs are there but it is not accessing them. Any way to access those or the files if nothing else? I would rather not just use scrounger at this point unless absolutely necessary. It seems like firefox should have a default to save more than just one recent backup and it would help a lot with this kind of messup. Thanks for any ideas.
