Greetings support team. The problem is a bit complicated and I could't find anything similar to it on the net, so I'll try to explain in details what happened. One day after opening the browser I noticed that it didn't launch(there was no window). After opening it again I saw that all of my previously opened tabs were gone. After that I closed Firefox and went to check the task manager. I found that Firefox was still running after closing it. I couldn't wrap my head around it and killed the programm. Then I opened it again and got the same results: first launch: no Firefox window(nothing on the taskbar either), secound launch: one empty tab. After that I opened a new tab in Firefox through task manager and my screen "swiped right", I got access to Firefox window with all of my previous tabs, but all the other programms I had opened on the taskbar were gone. Somehow Firefox opens outside my screen on a "separate one" every first time I launch the app, and the only way to switch between "screens" is to open a new tab through task manager or launch a program that was previously active to switch back to previous "screen". It is also impossible to switch between opened windows on different "screens" using gestures on the touchpad or "Alt" + "Tab". I use a laptop and never even tried to attach/connect a second monitor. I don't have another monitor attached via bluetooth or any other means in device manager. I have the latest verion of windows 10 installed and updated. I have another PC, where I use the same Firefox with the same addons on the same Mozilla account, which has no such issues. I have tried renaming the file called "xulstore.json" to "xulstore.old" or deleting it entirely, this didn't resolve the issue.

Why is Firefox backing up my bookmarks in a json file, when Firefox itself doesn't recognise the file type when trying to restore said bookmarks? I WAS able to restore my bookmarks by converting the json file at https://www.jeffersonscher.com/ffu/bookbackreader.html. But why can't Firefox just back up as an html file like to used to? I had to go off searching the internet for a solution, turning what should've been a 5 minute job into nearly an hour 😕

ALT-SHIFT-LEFT has been 'select word backwards' for years, at least on macs. And so it was on FF too. Now they suddenly decided to re-map it to 'select left tab'. There was already a key for that - CMD-ALT-LEFT. Which also works for the right, whereas ALT-SHIFT-RIGHT does nothin

Hello. I am not familiar with this end to end encryption that Facebook now does for Messenger but now when I try to use Video Calling/Chat it tells me it is not supported by my browser, Firefox. I have never had any problems with it before. Is there a fix? Thanks

since the last update, the shortcut keys to highlight a word at a time left OR right are both highlighting the next word AND also jumping to the last tab. AGAIN! I noticed this was identified as a problem back around 2019 in a search. I now cannot move fluidly within text, nor highlight a word at a time quickly. Either it's whole line or simply a letter at a time... which results in a pretty incompetent, crippling experience. PLEASE FIX!!

Hi! I'm using Firefox 126.0 on Fedora 39.

Pages from Amazon.co.uk load very slowly, incompletely, or not at all. All other Web sites are fine.

I had a couple of certificate-related errors saying that the identity of the site couldn't be verified, but I can't reproduce the problem, so I can't quote the exact wording, I'm afraid.

The same Amazon pages load properly in Chrome on the same machine, and they load properly in Firefox in a VM on the same machine. That tells me network connectivity must be fine.

I've tried disabling all extensions, reverting to the default theme, running in Troubleshoot Mode, clearing cookies and site data, clearing the startup cache, disabling hardware acceleration, and creating a new profile. The new profile helps slightly, in that it loads more of the page before getting stuck. Nothing else helps at all.

I'd prefer not to refresh Firefox if I can avoid it, because I don't want to lose all my plugins and settings. This installation is five years old. Besides, a new profile didn't fix the problem.

What's the next thing to try? I'd really appreciate any ideas.

for a recent update or two, when I am watching videos in fullscreen, at least like me, for example, when I entered fullscreen, the video should play horizontally, but after merely half a minute, the screen orientation goes back to vertical mode automatically, which is not happening when I began to use Firefox android months ago. Watching same website on different browsers, only Firefox goes wrong, so I think this should be Firefox's bug.

Hey there,

during work I often open two windows of Firefox to have more information visible on my two monitors. Unfortunately I sometimes forget that I have a second window open, so I close only my "main" window and loose all tabs.

Is there a way to force Firefox to ask to close a window and loosing multiple tabs for every window open?

Right now this only happens for the last open window.

PS: I just found out about the keyboard shortcut of restoring a window (CTRL+SHIFT+N) recently. I would prefer a setting in my case.

Thanks in advance Fred

Is there a way to create a new keyboard shortcut to copy current tab URL?

I've been using Arc to try some of their features, and what I miss the most is the hability to copy current URL to share without touching the mouse.

Bought a new computer. All my toolbar bookmarks migrated across successfully. Sidebar symbol missing from the menu bar and I couldn't find where these Book Marks were at first. But then I right clicked on the menu bar, clicked on Manage Book Marks which opened a Library box and there they were. Does anyone know an easier way to access them please? Any tips gratefully received. Thanks, Bob

I'm trying to move away from using Google, so I swapped to Duckduckgo and removed Google as a default search. However, "Search with Google" is still appearing in my search suggestions bar with a pin icon in the corner, and I can't figure out how to remove it. Does anyone know how to do this?

I upgraded from 126.0.1 to 127 today. Upon update, all my windows are gone. The only way I could access them is to revert to an older profile backup and reinstall 126.0.1.

I tried exporting my session with Tab Session Manager in 126.0.1 and reopen them in 127, but that only restores the last tab of each window (oddly). The json clearly lists 3 windows each with multiple tabs. I tried copying the sessionstore-backups folder, but no dice.

Hello,

A couple of months ago I discovered that I no longer have the ability to edit, delete, or dismiss a shortcut from the home page of my desktop. I did read that the 3 dots will appear if I hover over a shortcut. I tried that several times on different shortcuts but the 3 dots never appeared. Is there another way to edit, delete, or dismiss a shortcut? Or even better is there a way to restore the 3 dots?

I cleared my cookies, cache, history and data like I was told to when I connected a new router so all of my shortcuts have changed. A few that are there now I don't want and I do want to add several new ones.

Thank you for your help!

When I open Firefox these days, the window is so big that the toolbar is barely visible. I have to put the cursor in just the right little spot to pull the window down and resize it. It is NOT full screen or maximized, it just opens a huge window that's too far up on the screen. I just want to resize the default window that it opens with.

I cannot access grocery coupons from Ralphs Market. When I try, I receive the message: Secure Connection Failed

Hello,

I cannot open the uwyo.edu website on my Firefox browser. I have no problems with other browsers. I tried and checked the solutions people shared, but none of them worked for me. I checked the DNS and different networks, and I also checked the link below:

I would appreciate it if you could help.

Thank you and best regards, Farshad

Hi, it has been a while that one of the updates on firefox removed the ability to navigate using the middle click, i waited and waited for some day an update drop and fix that but it's been a while and nothing has come, i was sure to test this on another computer and it didn't worked as well so i'm pretty sure firefox has some problems, i mainly use a drawing tablet because i don't have a mouse, so navigating is a bit hard without the usual middle click nagivation(i'm not sure if there is an actual name to that), please help

I reset Windows yesterday to attempt to fix a problem with my computer. After redownloading Firefox and signing into a few basic things (including my Mozilla account), I realised all my logins were gone. I have followed the steps in [[this tutorial|https://support.mozilla.org/en-US/questions/1310179]] but it didn't work - I think saving logins in this instance of Firefox overwrote the other logins file, as when I opened it, it only had the login info from what I logged into after I reset.

Looking at my connected services, it seems the instance of Firefox from before I reset is still open. I mention this just because it's possible that this would contribute to a solution.

Any help is greatly appreciated as I have a number of securely generated passwords and cannot access a good deal of my accounts.
