Hi. Yesterday something weird and unexpected happened to my Firefox and amongst other things it lost all my open tabs, of which there was about 70 or so. Another strange thing which happened is a website I use turned into Japanese language all on its own and in the end I was forced to delete cookies for that website to revert it to English, even though it was never changed in the first place. My homepage shortcut tiles were also all rearranged and some deleted. I have no idea what caused all this, but the biggest issue for me is that I lost all my open tabs. I refreshed Firefox to try to cleanse whatever it was that caused this, but even before this I lost my tabs.

My question here is; I am sure that the history of those open tabs is still listed somewhere on a file and I can get back my previous session which had all the tabs on it, but I have no idea where it is or where to look. How do I do this and where do I find the older file with the open tabs.

Thanks.

Sometimes drag functionality stops working. I can't grab a tab to move it to another position or to a new window. (Holding left click on the tab and moving the cursor does nothing). Also, re-merging the tab with another firefox window stops working. (Dragging a tab to a firefox window from another firefox window doesn't merge them. It does nothing) I can right click on the tab and select Move to move it to a new window but dragging stops working. I have to close Firefox and start it again (sometimes twice), then dragging starts working again. This happens multiple times a day. I am on Linux Mint and the version is 126.0 (64-bit). This problematic behavior has only recently began.

Hi,

I have the following problem: Windows 7 crashed after coming back from standby. When I restarted Firefox it restored a 3-month-old session. The sessionstore.jsonlz4 file was missing in the profile folder. I searched for a backup in the sessionstore-backups folder; unfortunately all were too old. Windows Restore was not running on my computer.

Using EaseUS Data Recovery I found a recovery.baklz4 file from 10 days ago, tried renaming it etc. but Firefox won't use it for recovering. It is probably corrupt ...

I used https://www.jeffersonscher.com/ffu/scrounger.html but I get an error saying: Session history file contents could not be read?

Is there any way to repair the file or extract the URLs to use them manually?

Or any other solution is very welcome! Thank you very much!

Hello, I used to have Microsoft Teams as a pinned tab (in fact I think it was my first pinned tab), which I no longer need as I now have the Teams app on my computer. I have tried unpinning the Teams tab but whenever I close & reopen Firefox, it reappears - it doesn't show up initially, but will pop up 5-10 seconds after Firefox starts (my other pinned tabs show up straight away) - so I have to close it each time. Not a big issue I know but kinda annoying - any suggestions/solutions?

Mozilla tab keeps crashing (especially at YouTube) I was wondering if someone can help me find out why!

like tell me how to show the log or something to identify what is doing the crash.

Thank you in advance!

Hi,

Is this new feature? Once I click on link with middle mouse button, that tab is opened and switched to it. Previous firefox versions only opened tab and thats it. It is very frustrating. I want open multiple tabs and then view those tabs. Now I have to, suppose I have 5 links listed in webpage:

I middle mouse 1st link Then I have to return to my previous page I middle mouse 2nd link Then I have to return to my previous page I middle mouse 3rd link Then I have to return to my previous page I middle mouse 4th link Then I have to return to my previous page I middle mouse 5th link Then I have to return to my previous page

If it is new DEFAULT, then please make ant option to switch back in about:config, thanks!

After i closed firefox with two windows it only restored the wrong tab and because most of the tabs were open some time ago i cant restore it from history too. Can i somehow restore them?

Recently the V-like icon/button appeared at the right-hand end of the top line of my Firefox windows. This Tab Search could be invaluable to some, but I have no need for it. If I start to get too many tabs I just use another window. However, I click on it constantly when I intend to minimize the window. I have been clicking on the - icon/button in EVERY WINDOWS APPLICATION since Windows began, and as it has ALWAYS been the LEFT-MOST item in the UPPER RIGHT CORNER I haven't had to think about it in decades. But now it isn't the left-most, that is now tab search.

Please, please, PLEASE provide a configuration option to remove Tab Search from the top line.

Thanks!

Hi firefox community,

I am using Firefox version 127.0.2 as my main browser on MacOS Sonoma 14.5. For the past few months, when using Firefox in Mac's full-screen mode, I've been experiencing an issue where one of the multiple open tabs unexpectedly displays in a separate window the moment I click on it.

This behavior didn't occur previously, and I believe it started happening about 3 months ago. It doesn't happen every time, but occurs a few times a day when I least expect it, making it difficult to identify the specific conditions that trigger it. I use a Magic Trackpad, and after switching to full-screen using the three-finger gesture, the moment I try to activate a specific tab, that tab alone displays as a separate window in full-screen mode.

Is it possible that a Firefox version update has changed this behavior? If this is a Firefox issue, is there a way to capture debug logs to have the developers investigate it?

Alternatively, if there's an option to prevent tabs from opening in new separate windows, that would be an effective workaround. Could you please let me know if such an option exists?

Best regards,

I don't like the default homepage provided by Firefox, so I found an extension that can offer better tabs. But when I open Firefox, my homepage doesn't show the page provided by the extension. It's still Firefox's default homepage. Only when I open a new tab will the page provided by the extension appear. Also, the settings don't offer the option to replace Firefox's default homepage with the page provided by the extension. I need to replace the homepage from Firefox's default homepage to the tab provided by the extension.

It won't save open tabs when I close Firefox. Each time I have to go to: Setting>>History>>Recently closed windows. In General settings it's ticked Open previous windows and tabs. I already tried to turn off all extensions.

I created a few virtual hosts and sites on my local machine and this is working perfectly.

Problem is with Firefox, when I enter non-existant url in address bar, Firefox force me to search and don't let me to open the url, but I need to go to this url for testing, developing, etc...

Any solution?

A few years ago jscher2000 gave me wonderful instructions for how to create some of the features that were once easy for ordinary users like myself to control through an Extension called TabMixPlus. Apparently there was some big disagreement between the developer and Firefox and they completely disabled it. At any rate, I'm continually frustrated when I accidentally move a pinned tab to a new window while trying to move or resize Firefox. I would like to know how, in about:config, I can create a setting with which I can protect pinned tabs. Thanks.

This is an annoying issue because I frequently have multiple windows opened on multiple monitors. If I close the window that has all the tabs and open a new instance of firefox, the pinned tabs disappear. Such an awfull design. The pinned tabs should replicate to all other opened windows and stay pinned until the user manually unpins them.

An unwanted bookmarks toolbar appears above the URL field, as shown in the image.

After all the bookmark shortcuts it contains are closed, and FF is restarted, the marks reappear.

How can they be purged permanently?
