When I am deleting emails, I frequently end up with the same email as most recent in my inbox and thus automatically selected. This opens a new tab with the same email as content and soon my tab section is filled up with multiple versions of the same few emails and the inbox tab pushed off the screen.

Can there not be a setting to open up the existing tab if it has the same content. Or alternatively a way to pin the folder tab (normally inbox) on the left of the tabs permanently.

Other tabbed applications do not open up multiple tabs with the same content.

Yes I could shut the unwanted, repeated tab each time Thunderbird opens it, but I don't want to have to.

This seems like an easy feature? Please??

Hello Good People,

I installed Firefox a few days ago and it was looking good. I don't like that icon in the top-left hand so I right clicked it and removed it. All was good. However, today there is a blank black space in the corner as if the icon was back (but without an actual icon). It's only a small thing but it bugs me. I want the tabs to be shifted all the way over to the left like they have been up to today. It's triggering my OCD. Anyway, any advice appreciated.

Best Wishes

Matt Hammond

I have many tabs open at the same time and I'm noticing tabs from Urban Dictionary in particular are automatically changing to suspicious sites, quite a few porn sites in fact.

Is this something Urban Dictionary is doing to direct viewers to sponsors or is there a bug in my FF browser?

I am afraid to update to Firefox 124 for fear of losing the existing order of 100s of open tabs if the default setting of ordering tabs by "Recently Opened" kicks in before I have a chance to change the setting to "Tab Order". Can anyone help me? I'd like to upgrade to 124 if I can do so safely!

Lately, Firefox for Android has started "forgetting" active tabs. I have changed absolutely nothing in the settings. Most of the Active Tabs I've had for years are gone. Now I only have about 5 left & they get corrupted every couple of days. For example, the 3rd one in the attached Screenshot: I'm playing "catch-up" on old Guardian crosswords, currently on 15,179. At irregular intervals, say every couple of days, it gets replaced with an older one, 15,166 for example. I suspect it must have been changed in the Version released on March 19, 2024 (124.0)

Sooo I had tens of tabs open, with intention to keep them - I couldn't find an option to save all of them, so decided to update the app, just in case FF caught up with some functionalities I've seen in my other browsers - bookmarking all tabs, namely.

After I've updated, all my open tabs are gone and "recently closed" is empty. There's no way to have the tabs back.

I don't expect there's a way to solve this problem, but I'm posting it here just in case, and at the same time marking my segue to Safari.

On all my new tabs which open with "Recommended by Pocket" items, the "Sponsored by ..." items are in German. All my language settings are "en-amer".?? All the other items are in English.

Why isn't the Restore Previous Session choice available on the Open Application Menu? Even if I click the checkbox under Tools/Settings/General/Startup: Open Previous Windows and Tabs (version 107/windows 11), I am presented with a tabula rasa screen on reopening my Firefox session. Your help/support says to go to the Open Application Menu/History and choose Restore Previous Session (located between Recently Closed Windows and Clear Recent History). However the Restore Previous Session is not listed. Not sure why Firefox can't get this right since you have had it right for the almost 20 years I have chosen it as my default browser.

I'm having a problem sharing websites with others via, for instance, Signal. Telegram, WhatsApp or a social medium. There used to be a share button in the toolbar, but this I cannot find anymore. At some time there were also the three dots in the address bar that dropped down a menu for the page, which included a 'share' option. These dots seem to have vanished. Also I vaguely remember that the "share" function was also in he tab context menu once upon a time. However dropping down that menu does not reveal any "share" function presently. Then there was, if I remember correctly, the possibility to click the File menu at the top of the screen and then click on the Share menu item over there. But also there the "share" function seems to have vanished. I also looked in the settings menu, to find if there is a setting there which switches on or off the sharing function. I could not find such a setting. In short, it seems that I am horribly overlooking the "share" function. Please help me find it. Thanks. (Firefox 112 for Manjaro Linux)

Firefox unexpectedly closed on me and when I opened it up again it did not immediately give me the option to restore closed tabs. So I went to the menu to click on restore closed tabs there but the option was not provided to click on. How do I restore tabs under this scenario? Thanks.

By mistake, I close a window with lots of opened tabs and can not get them back. In the past when this happened I went to history but now there's no available option in "recently closed windows".

The option to restore tabs and windows is no longer working for me. I normally have a dozen tabs I work thru every day. Yesterday when I shutdown Firefox, all those tabs were there. Today when I open Firefox it only had to single Firefox default homepage. Checking under History there is no option to restore previous tabs, and the recently closed tabs was empty.

To test, I opened an IMDB page and pinned it. I then went to Wikipedia. This gave me a pinned and unpinned tab. I shutdown Firefox via the "X" to close the window. When I restarted Firefox there was only the default homepage. Neither IMDB nor Wikipedia showed up under recently closed tabs and no option to restore the previous session was available.

I have operated Firefox this way for several years. I don't know why this behavior is no longer being supported.

Hello, I want open a private tab along side of an opened private tab . But every time it opens in an new window. So, i am shifting from chrome. In chrome when we try to open a link in private tab all the private tabs opens in the same window. So, I want to is this feature available in Firefox or not. If have how can I turn it on. Thanks.

Hello, for my study I'm searching a lot of information on different websites for different school subjects and have currently accumulated over 1000 tabs open/active in my Firefox (web) on my laptop. I usually open websites and don't close them with the assumption and just to be on the safe side I might need them later. However, I would like to group/bundle these tabs into different categories according to the subjects I'm working to keep it manageable. Is this possible (preferably not by means of an add-on)?

I've had Firefox since it's been around and not had this issue, I have a Mac with OS Monterey 12.6. Firefox is up to date and about two weeks ago with about 10 tabs open a tab crashed which probably hasn't happened in a couple years. I tried re-opening but it just crashed. I clicked the next and it crashed, then to the next and it crashed, etc. They all crashed soon as you clicked on them. I switched over to Chrome to see if I could even look something up because as soon as you clicked on anything with Firefox it crashed. I restarted Firefox and tabs just crashed. I let it sit and came back 8 hours later & all worked fine. A day later tabs started crashing again. On and off for the last two weeks tabs just keep crashing intermittently on Firefox and they only way to fix it is take a break and come back in an hour+. Then maybe a tab will crash and it will continue to work for a little while when you restart tab or maybe it will just crash as fast as you click Restart Tab. I currently have 2 crashed tabs and I'm surprised its letting my type this with a crashed tab, when I tried opening another, it just opened a crashed tab. I wouldn't doubt if it crashes in the middle of typing and I have to come back in an hour to finish. I can't find a solution on Google and if this keeps up, I'm going to have to drop Firefox as this happens throughout the day for work. Any Ideas what this might be? If you think it's a computer issue, I'll call Apple, but no solutions on Google make sense. Thanks for any help.

Note, these tabs are crashing on every site you can think of from Yahoo, Mail, Google, Facebook, Amazon, youtube, etc.

Last October my sessions were gone after a Firefox Update. I asked for help here: https://support.mozilla.org/sv/questions/1394685 and eventually got kind help from @cor-el (that unfortunately wasn't skilled enough to understand) and from @RayGibson57. But by then, my life was in a flurry and I didn't have time to try the advice. And so, after a while I had, with some effort, gathered many of the old tabs back again, and built up new sessions.

This Monday I was trying to internet while having high fever (something people should never do :o ). I left three blank windows open when I shut down the computer, and next morning those three were the only ones Firefox wanted to remember.

(I still find this change frustrating, bordering on infuriating: what happened to "Choose how many old sessions you want Firefox to remember", I think the maximum was ten?)

Now the fevers left and I went to those answers to try. That Q/A was archived though, so I'm starting again here, from as far as I got following King Rays instructions. They were:

1. Open the application menu (3 horizontal lines) next to the address bar.
2. Click on Help -> More troubleshooting information.
3. With that page open, find Profile Folder and click on Open Folder. That's how you get to the folder with backup files in it.
4. Set computer up to see all the extensions & system files. By default, the extensions don't show up (.jsonlz4 is an extension).
5. I found an older file in that sessionstore-backups folder and copied it one level back to the main profile folder.
6. Renamed the sessionstore.jsonlz4 to sessionstore.jsonlz4.old and the file I copied, I renamed to sessionstore.jsonlz4.
7. Opened Firefox and that missing window was in the history so I could open it.
8. Don't make any typos here, because Firefox won't find the files it needs to open.

I got as far as finding the Profile folder and the sessionstore-backups folder.

But I cant find any jsonlz4 file called "sessionstore". Only a "sessionsCheckpoints" and that one is a json file, and the date modified is today.

See screenshots please!

Can anyone talk me trough this like Im a grandmother from Sweden with extremely limited coding & tech skills (which is what I am)?

Got up this morning and FF said all my tabs were crashed - GAH! Could not open ANY new tabs, not even a blank tab, without getting this message. Clicking on restore tabs did nothing. Closing & opening FF did nothing. Cleared startup cache & uninstalled ublock origin (the only extension I had) but that did nothing. Refresh firefox did nothing (except lose some of my preferences). Went to about:crashes and all it says is "No crash reports have been submitted." Every other suggestion I found online was beyond my comprehension. FF DOES work in troubleshooting mode only, but I lose some important functions in that mode. I've been using FF almost since it was born and have NEVER encountered a problem like this before. I hope someone can help!
