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!

In my location, my only option for internet access is a mobile hotspot with limited data. Consequently, I am always mindful of my data usage when using my laptop. Despite primarily browsing static pages, email, and other low-data activities, I often find my data usage higher than anticipated. The main culprit comes to mind to be videos embedded in news articles. Sometimes, with multiple tabs open, I switch to an inactive tab only to find a video playing. Although I've configured my Firefox preferences not to autoplay videos, it seems that YouTube videos still override these settings.

So, my question is, when a tab is inactive, does Firefox stop all data transfer for that tab in the background? And if not, what are the solutions to stop any background data other than continually closing all tabs?

Also, any suggestions on this topic are appreciated, especially from and to users who also live in remote areas without fiber, DSL, etc.

I was running 8 Windows with about 12 tabs per Window. AND I had it set to Continue Where You Left Off, so that each time I closed and launched FireFox, ALL Windows with ALL Tabs would open. No problem. Easy.

This morning, Firefox crashed and LOST EVERYTHING. Why did it happen? And how do I get them back?

Everytime I try to open a tab on my Firefox window, it loads for a second before a blank screen saying that my tab has crashed. The only times I can open a new tab is on a private window.

Just recently been getting yahoo search engine results to open in new tabs rather than the same tab. I have searched for other users that have the same problem and have done the tracking protection thing and deleted cookies, but nothing helped. Also tried Troubleshooting Mode and it still persists. Any other ideas that may help? I'd appreciate it.

Since a while, when I click on a link in a Google search result, the link opens in a blank tab (about:blank). Opening the link via the context menu "open in new tab" works without any probem. This happens on a iPad with iPadOS 16.7.6 with Firefox 124.0 (39709). FF is set as standard browser. Does not happen in Safari or Chrome.

I used System Restore in Windows because I lost my Search Engine in Firefox and it didn't exist in "Customize Toolbar" option. I researched how to get the Search Engine back but nothing worked. I thought System Restore would solve the problem. Now I can't restore my previous Firefox session. And I can't find a sessionstore.jsonlz4 file. I read you have to rename a file in sessionstore-backups folder to sessionstore.jsonlz4 but I don't know which file to rename. I also read you can restore a recent upgrade.jsonlz4 but that is dated 3/5/24. I loaded previous.jsonlz4 file using the Scrounger tool but that didn't restore the session I had. (The previous.jsonlz4 file is dated 3/22/24 about 45 minutes ago.) I want to restore the session I was using earlier in the day. And "Restore Session" option has disappeared from the Firefox History dropdown menu. I tried the "Restore Firefox" option but that didn't help anything and it made my dropdown menus disappear. I have no idea how to get the session back that I was using earlier in the day.

Is there a way to search through my open tabs? If not, PLEASE create that feature.

Also, is there a way to see the previous pages that have been opened in a tab? Right now, I have to just keep backspacing through previous tabs hoping to find the one I'm looking for. If not, please ad d a way to view and select previously opened tabs before I start backspacing through them.

Is there a way to sort open tabs, at least alphabetically? If not, that would be a very nice feature to have.

I'm using Android 12.

Thank you for your help.

I’ll use the example of movie times. In the IMDB app you can pick movie times, that link sends you to my web browser (Firefox) which opens to the homepage, but that’s it. It doesn’t do anything else, it doesn’t even attempt to open a page. It’s been happening for a while. What am I doing wrong g?

For ages I've had my tabs automatically restored when opening Firefox. But as of the last few days it won't. The old links are saved so I can restore them one by one through history but that's not automatic. And if I click on restoration in History it will bring up a whole bunch of old tabs not neccessarily from the last session.

I'm on the same computer as I've been for over a year, so I don't know what what the problem is. I've searched on it and tried to re-check the box for this function. But it won't apply...

I have pinned various shortcuts in the New tab to link to websites I frequently use. I use two different laptops and both are configured the same. However the New tab randomly clears the pinned shortcuts. I have attached two screenshots illustrating the changes.

I'm not aware of anything I do that caused the shortcuts to be deleted. When they are pinned I think they should be there permanently.

This is the procedure I followed:

Close firefox

Copy previous.jsonlz4 file to the main level in the profile

It has all the tabs i used to have in it because I made a backup a few days ago

Rename the file to sessionstore.jsonlz4

restart firefox

I get the same single tab I had before i did this

when i go to history tabs, all that is there is the single tab i currently have

Appreciate your help/gary

I'm having the same problem as this guy.

I have a large number of open tabs in Firefox on my iPhone, a mixture of old and very old. I've been trying to go through the tabs and deal with them -- in some sense they are all todo items that I left open at least semi-deliberately.

If I tap on a thumbnail to load a tab, Firefox instead loads a blank page. If I tap the address bar after that, Firefox loads the new tab page, not the site corresponding to the tab that I selected. If I tap and hold a tab's thumbnail, Firefox crashes.

It was the case temporarily (possibly a bug) that some of these tabs would place a TLS failure icon in the left of the address bar when selected, while the blank page was displayed. Tapping on that would display the tab title, but not the tab URL. No longer is that TLS failure icon ever visible.

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?

When I press the home button, the tab I was on remains in the background and a new tab is opened if I tap on one of the shortcuts. Is it possible to make it so that it stays in the same tab like on PC?

When I try to open a link from an external software, in my case mostly discord, that which I click on, I get the profile manager opened, ask for which profile I should open from. If I already have the Firefox window for that profile open, I have to close the whole window and then it opens with all the tabs with a tab for the link I clicked on.

I would like to open tabs like how Chrome does, not asking for profile (yes, I know, I can just make things open on only one profile but I want to choose which one I want it to every single time without manager) and instead opens up from the profile window that I just had on.

I would like to open external links on an existing window and not close to open it.

So, ultimately, make my Firefox open link from the latest profile window I was on, and it does not require to close an existing window to open the link.

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

OVER THREE YEARS PEOPLE HAVE BEEN DEMANDING THIS. When I tap a link in an app, I want it to open IN FIREFOX. Not some custom tab. Not some special pseudo in-app environment. IN. FIREFOX. EVERY OTHER browser on Android can do this. Don't give me some BS answer about removing Firefox as my default browser, either. That causes it to either open in the app I'm using, or the phone's built-in browser, NEITHER OF WHICH ARE SECURE. If you really care about security, like you're trying to sell us you are, you will fix this yesterday.
