In the plugin "facebook Container" I have made a new "tab category" called "social media" with a blue sign. The problem is that firefox continues to open FB in the old category even if I delete it, which is also very hard to do as I have to close all my FB-tabs to be able to delete it in the options tab. Next time I use firefox or a few days later firefox has again undeleted the old FB category and again opens my FB tabs in black tabs instead of my new blue tabs. I can´t use my own new tab category as long as the old one is there and it keeps comming back after I delete it. Very annoying to say the least! Please fix this error as soon as posible, thank you.

I'm trying to use a custom start page on new tabs opening (not happy that I have to use an extension for such basic functionality btw) but my service worker does not seem to activate or used when opening. Opening a new tab takes multiple seconds.

Navigating to the site (I have my start page hosted on AWS) on an existing tab is instantaneous, as is refreshing this page once the tab is loaded. So what gives? As far as I can tell Firefox doesn't install service workers on a per-tab basis, so there should be no issue here.

My previous session didn't automatically reopen when I restarted firefox. When I went to the help section, it told me to click "restore previous session" from the menu, but I don't have that on my menu. The example shows it after "new private window", but my menu has "zoom" in that spot. I noticed that the "sync" isn't at the top of my menu either. I had this problem once before, but it was long ago, and I don't remember the solution. Hope that I'm describing my problem well enough. Frustrating for a senior, trying to stay safe.

Hi,

I always have dozens of tabs opened, if not hundreds. They have vanished. I’ve been trying to follow the topics on the matter, such as the one named ‘Session won't load’ (questions/1254740), to no avail.

Finally, this time I remembered not to close Firefox when I saw my tabs where suddenly missing. I’ve never seen the ‘Restore the previous session’ on the Firefox menu, and neither did I this time. Without closing the browser, I did a backup of the ‘sessionstore-backups’ folder. It contains:

‘previous.jsonlz4’, from 22/11/2020 17:42 ‘recovery.baklz4’, from 22/11/2020 18:57 ‘recovery.jsonlz4’ from 22/11/2020 18:58 ‘upgrade.jsonlz4-20201027185343’ from 31/10/2020 13:42 ‘upgrade.jsonlz4-20201108180448’ from 10/11/2020 15:05 ‘upgrade.jsonlz4-20201112153044’ from 22/11/2020 10:34

The one I need is ‘previous.jsonlz4’, since by 18:57 I’ve already lost my tabs. From the update backups I think I could also use the one from 22/11. In any case, I don’t understand what I am doing wrong so as to recover the ‘previous.jsonlz4’. This is what I’ve tried from different threads on my profile folder:

The ‘-backup’ and ‘OLD’ changes belong to different attempts

- Rename (on ‘sessionstore-backups’ folder) ‘recovery.jsonlz4’ and ‘recovery.baklz4’ to ‘recovery-backup.jsonlz4’ and ‘recovery-backup.baklz4’, and also tried with ‘recoveryOLD.jsonlz4’ and ‘recoveryOLD.baklz4’ - Rename ‘sessionstore-backups’ folder to ‘sessionstore-backupsOLD’ - Rename (on the main profile folder) ‘sessionstore.jsonlz4’ file to‘sessionstore-backup.jsonlz4’, and also tried with ‘sessionstoreOLD.jsonlz4’ - Copy/paste the ‘previous.jsonlz4’ file into the main profile folder. - Rename ‘previous.jsonlz4’ to ‘sessionstore.jsonlz4’

Nothing has worked. Once followed the steps, Firefox keeps opening my startup page. Note that it does not restore my previous session (that is, some tabs regarding this same subject), but my startup page, which means my attempts are having some effect, although not the desired one. I do have the ‘Restore previous session’ checkmarked in ‘Setting/General/Startup.

I also tried to replace ‘recovery.baklz4’ (on ‘sessionstore-backups’ folder) with ‘previous.jsonlz4’, from 22/11/2020 17:42, hoping to be prompted with the ‘Well, this is embarrassing’ + ’Restore’ window. I had no success.

I’ve been trying to recover my tabs for hour by now and don’t find what I am doing wrong. Why does Firefox refuse to load my ‘previous.jsonlz4’ file? Am I missing something? Maybe ‘previous.jsonlz4’ is corrupted or something? Should I try to use the ‘upgrade.jsonlz4-20201112153044’ from 22/11/2020 10:34 file? (Although I would lose some information)

Some people talk about a ‘History > Restore Previous Session’. I cannot find anything similar.

Thank you very much

Firefox unexpectedly quit, open tabs lost when MacBook Pro's charge died. After charging, did restart since Menu button to access History was missing (only menu bar visible). It returned, but unable to restore closed tabs (as I've done in the past) - History shows it to be "empty." I've spent hours searching Mozilla Support...can anyone please help? These 8-10 tabs must be somewhere!

I'm not sure how, but sometimes when closing firefox with or without a restart of the pc, the second tab of my last session dissapeared. The first tab is my mail and stays, but the second tab is sometimes missing. If I close now the browser and start the browser again, the second tab is still there, but today I didn't restart the pc but firefox was closed for a while, I am missing the second tab. The second tab I have now, was the third tab before.

I'm running Windows 10 (Version 2004) and firefox 83.0 (64-bit) and have 157tabs open at the moment.

i have one url that everytime I click on the tab, or close it completely, and type it in again, it always opens up at 30% zoom.

I can get rid of it easily by clicking on the 30% in the url window but it is completely annoying.

I am not sure how i did it in the first place and i am wondering how to get rid of it, or at least change it so it doesnt come back.

Hi dear Community Members, formerly when I opened a link in an email from my Outlook account, it opened in a Tab exactly next to it. But now it goes beyond several tabs which were already there. How can I get these links again opened in a Tab right next to it. That makes it easier to go from my email to that tab and back, I find.

Hope that I described this clear.

Thanx, Jan

These scrolling browser tabs are driving me nuts.

Is there way to stop the scrolling? Is there a way to have more than one row.

I found an addin but I really don't know how to use it.

Thanks.

Four times now I lost all the tabs I had been saving in Firefox. No explanation, and no apparent way to recover them. Why does this happen? Is there a way to recover them? I don't have this problem with other browsers. Very frustrating, because some are regularly used references. Some are hard to recall from scratch once they are suddenly gone.

tabs keep scrolling to the left. actual one i want to see stays on the right but view keeps going back to the left. Same with option scrolling thing when i press ^ instead of showing options it just flicks and doesnt let me choose anything. help! its quite frustraiting

I need to know how to get the browser back to its normal functionality. I cannot right click on pretty much anything without it opening something in a new tab. It's infuriating and I can't find the answer on google. Does anyone have any solution? It breaks my workflow to the point where I am considering switching bowers. Have happily been using Firefox for 10 years without this problem. Reinstalling does nothing.

I think the real problem is that it opens the little context menu and then immediately clicks the first option. For example if I right-click a misspelled word it just fixes it automatically.

I think it was update, my pc restarted. But it usually asks weird. I lost all windows and all tabs. Yet in library/history under restore windows, there is nothing! There was some json file, from which you could get tabs. I tried it last time and it didn't work. Also firefox wasn't even running at that time and previously i had all windows and tabs... Are you kidding me???

I lost like hundreds of important tabs.... Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa............

I often experience situations on Firefox where I lose all of my important tabs which I never end up getting back, despite having 'restore previous session' turned on. For instance, it happens when a software forcefully opens a "Thank you for installing" site while Firefox wasn't running, or when I accidentally open a link in a new window while being on private mode, when I meant to open it in a new private window instead..

On a different browser I used before switching to Firefox, I used to resolve this by going to it's profile location and looking at two files named "Current Session" and "Last Session". I could just rename the "Last Session" file to "Current Session", and all of my tabs would return. I was hoping Firefox would have something similar, but it seems either impossible or maybe just a bit more complicated, since I cannot find anything regarding this on the web.

Each time this happens to me, I go to my Firefox profile folder but cannot really find anything regarding sessions I could replace and restore. Only thing I managed to back up from the various important tabs I lost were six files in a fashion like this:

recovery.jsonlz4, upgrade.jsonlz4-[a lot of numbers]

Can I use these files to recover my lost tabs somehow, similar to how I used to do it in the different browser? Hopefully I'm understandable, it's a bit complicated to explain for me.

Hi. I would like to restore my previous session when I open Firefox (last version of the browser installed). The option is turned on, but nothing happens when I close the browser and I open it again. The support says I should see "Restore previous session" after "New Private Window", but this option is not there. In the history, the list of recently closed tabs is always empty, there are juste one or two links in the recently closed windows (it seems to be a random list). Can someone help me ? I don't understand why it doesn't work. Thank you :)

Hi,

Writing in some distress here. Had Firefox open with a lot of tabs, most relevantly hundreds of pages relevant for my PhD research, when my computer decided to re-start on its own. When I opened Firefox afterward I was greeted by the "What's new with Firefox" page, all my tabs gone. Both "Recently Closed Tabs" and "Recently Closed Windows" were completely empty. "Restore Previous Session" is greyed out and unclickable. After looking up solutions to this problem online I went to my profile at C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles, and discovered there was no sessionstore-backups folder there. There is a file called sessionstore.js, but it has last been modified May 2017. I checked and my history is still all there. Is there anything I can do, or do I need to go over the thousands upon thousands of entries there in search of the ones relevant for my research?

Hi. I have a problem with the volume in my firefox. It seems the tabs all are set on a different volume. One tab is really loud, one is barely audible. I notice it when i open youtube on multiple tabs, and set the volume of the players to full, the tabs won´t play the same volume. I don't know why that is, or how to change it. Please help.
