I accidentally closed both of my Firefox windows with an "x" and the rebooted my computer. After the reboot there is nothing under "History"->"Recently closed windows" and "Recently closed tabs". Is there any way to get my windows back?

Hi, Moz://a Support Team

I hope you're doing well,

I'm encountering a problem accessing the Moz://a website due to a persistent pop-up error message. Could you please assist me in resolving this issue?

Any guidance or assistance you can provide would be greatly appreciated.

Thank you for your help.

Hi everyone,

My computer crashed while updating from Windows 10 to Windows 11. Unfortunately, I had someone look at it and he formatted my hard drive and only did a partial backup of files. I thought my Mozilla Firefox account was syncing, but it seems like it did not happen in a while. Does anyone know if there's any hope in recovering the lost tabs and bookmarks? Any help would be appreciated. Thanks,

Kenan

After updating to Windows 11, all my Firefox webpages backgrounds are colored black even after choosing a light theme which only changes bookmarks and toolbar to white. I want white background like my old Firefox ?

Hello, Firefox somehow crashed. Opening did not reinstall the tabs. This has happened couple of times in the past 10+ years and I was able to recall from History to reinstall the Tabs. Now I don't see that function in the Menu. Please help. I know there is a time limit to re-install them.

If I am on a web site and click a link to another page on the same website Firefox opens a new tab rather than displaying it in the existing tab. How do I get Firefox to NOT do this?

I recently sent a lot of tabs from my phone to my computer. However, when I started Firefox on my computer, since Firefox tried to load the content of all sent tabs immediately instead loading them lazily (which I think probably should be the default behavior), it took a very long time for Firefox to display even the tab that was currently selected, and I therefore decided to kill Firefox and reopen it, in the hope that all new tabs would load lazily. Instead, when I reopened Firefox, none of the new tabs where there anymore; it was as if they had never been sent. I would like to get them back, but I have no idea how to. Does anyone know if that is possible and, if so, how?

Ok, I've resolved this in the past, several version of Firefox ago, under windows. Firefox crashes silently, open it again and no tabs are restored. Open firefox again and look in recently closed windows and the one with my tabs is not there, only little utility windows that are popped up when I log in at the coffee shop, so my recently closed windows are overwritten with windows with no tabs.

So I go to my profile sessionstore-backups folder and copy it to the desktop. I have 6 files, previous.jsonlz4, recovery.baklz4, and recovery.jsonlz4 at around 8 megs in size. I copied each to the folder one level up and renamed them sessionstore.jsonlz4, and each time restarted firefox. All that opens is a blank tabbed firefox window.

There was never an existing sessionstore.jsonlz4 file anywhere I could find, even with firefox closed, this file never appears anywhere I could find it. Searching files with Windows was also unsuccessful.

I feel like I have captured the files with my tabs, based on the date modified, several were from before the crash. Why can't I find a working tutorial on how to restore my tabs? Nothing I've found on the support site works though I follow the directions exactly.

Thanks

I have been using Simple Tab Groups (STG) for a long time now. I am curious if putting tabs into groups saves any resources, i.e. is only the open group using resources (CUP/RAM), or is STG purely organizational in that all the tabs still use the same amount of resources as if they weren't grouped? If it is the latter, do you know of an add-on that would save resources? Thanks

when i have any of those 2 flags set to true it opens all links i middle click from firefox-view history all the way to left since firefox-view isn't a tab. I'd rather have it force them all to the right by default instead of it thinking i am not in a tab and have no tabs open

How can I import or to which folder do I import bookmarks so they show up in the shortcut rows in a new tab? I'm trying to get away from Opera but I love the shortcuts displayed on a new tab. I tried copying all the appropriate bookmarks to the bookmarks menu folder and why they are in the folder they dont display in the shortcuts.

The imagine shows where I want to import to.

I did a 'refresh' of my browser, thinking that basic user information would be saved. But I lost all my tabs in OneTab (extension). Is it possible to recover them?

Hello! Since updating to the last version (119.0.1), Firefox started keeping my open tabs between sessions. This is a behavior I don't want, and the only solution that I found told me to enable "clear history on close", however that is also not ideal, because I don't want to clear my history. The "Open previous windows and tabs" setting is off and my homepage is set to Firefox Default. I don't know where else to look for such a setting, except in the about:config, but even there I'm not sure which one is causing the issue. Any assistance would be appreciated.

Windows 10 Pro 21H2, Firefox 119.0.1

I followed the instructions at [[Unload inactive tabs to save system memory in Firefox|https://mzl.la/3AdRbLx]] but I still occasionally see the tab refresh when I select it. I start with a search on Bing, click an article to open a tab, follow links from there, back to the first tab and select another. I repeat this until there are several tabs open. Sometimes the page refreshes when I switch back to one that I previously reviewed. Is that controlled by the option browser.tabs.unloadOnLowMemory? if so, it doesn't appear to be working. [Edit] - The last time this happened I checked my system and found 10gig used of 64gig installed. I'm using the most current version of FF 120.0.1 on Windows 11 Pro v 22H2.

I had several windows open each with different tabs in them.

I shut down them down and switched off my Mac.

On restarting my Mac, one of the windows had disappeared from the restore session. I've checked my History but the tabs don't appear there.

I'm using the latest version of FF on a Mac Air M2

Please advise.

I recently downloaded Tree Style Tab. I still see the horizontal tab bar. I would like to hide it. However, I have tried just about every answer I could find on Mozilla, Google, Reddit, and any other websites that offered solutions. Nothing has worked since the last update. This includes the "type in about:config, toggle to true, open profile folder, create userChrome.css file, copy and paste xyz code, save, and restart Firefox" route.

Any help would be greatly appreciated!
