Firefox Community Forum

I have a lot of Firefox windows and tabs open, and I really don't want to lose my session.

I wanted to open a webpage in Firefox in fullscreen mode. But evidently there's some kind of serious flaw in Firefox that makes it incapable of opening webpages in fullscreen mode. Everyone says the only workaround is to open the webpage in kiosk mode. So I tried it.

But now I have two big problems:

1. One of my Firefox windows, with all its tabs, is stuck in kiosk mode. (Even if I close the window and then restore it with Ctrl+Shift+T, it's still in kiosk mode.)

2. All new Firefox windows I open with Ctrl+N are also stuck in kiosk mode.

I don't know what to do, and I'd really appreciate any help. Thanks!

Hi,

Firefox version: 139.0.4 (64-bit) OS: Windows 11

I have been having issues where Firefox tab will just crash out for no reason it appears and it happens at random times and once the tab start to crash, and I restore it, it will crash again and again. The only way tog et out of the loop is to restart Firefox.

I have tried: Refreshing/Reset, Clearing Cache and History removing all themes, disabling extensions, disabling my anti virus. Turning off hardware acceleration didn't make any different.

I currently have 2 extensions enabled: uBlock Origin 1.64.0 and Bitwarden Password Manager 2025.5.0

In the about:Crashes I have reported them all and they seem to have the same type of reasons in the Raw data/Minidump which are: EXCEPTION_ACCESS_VIOLATION_WRITE EXCEPTION_ACCESS_VIOLATION_READ

Any help as to what to try next?

I am sitting in hospital with a weird problem. The connection is open and thus not secure. I have successfully connected my 2 android devices, however my Windows Asus laptop is being barred by firefox. I only run firefox. It is a dead end because firefox refuses to allow me to access the net at all. So now I have to get my wife to go and download chrome and see whether that will work. Why can I not override as u understand the risks I also use Norton 360 with its VPN.

While I am able to log into my Google account in Chrome, I am unable to do so in Firefox after the latest update. Whenever I try, I am redirected to the attached support page, which asks me to delete cookies and cache contents. Deleting those does not help.

Please help!

Firefox added a new feature called 'tab group' that I love. Since I have many tabs, now I can group them in a 'tab group' and give it a name so I have fewer tabs and less clutter and can open a 'tab group' to display all its tabs. Kind of a file manager with folders and files but for browser and its tabs. The question is, how do I sync all tabs and tab groups in Firefox browser in all my devices so I can work seamlessly? One device is Windows 10 Pro,, another is Windows 11 Pro and the third is my iPhone with Firefox app. I would really appreciate some guidance.

Up until recently, my default search engine was Google. I recently switched it to DuckDuckGo.

I regularly use Ctrl+k (hereinafter ctrlk) to popup the window to enter a URL to create a link in whatever web app I am using (Microsoft Office 365 apps, Reddit, Quora, etc.)

Suddenly, in when I used ctrlk to enter a URL for a title I highlighted in an email, the cursor bounced up to the Address Bar and selected it. I've tested it, and ctrlk works to open the URL window when I switch back to Google as my search engine--except when I am logged into my Mozilla account--ctrlk brings up the URL window.

Is there any way to turn off the ctrlk/Address Bar shortcut? As part of my job, I write job aids and emails that have lots of links embedded in them so, for me, this is an accessibility issue as it take fewer keystrokes to activate the URL window using the this shortcut, and just a single roll of my trackball to get from wherever I am on a page to the Address Bar the few times I may i need it while writing. (Between having nine functional fingers and severe arthritis in my hands, I am not exaggerating my use of the word "accessibility".)

Thanks for any assistance I can get on this!

After my laptop BSOD, I had to re-install windows 11 while backing up all the previous settings and apps. I used "Free Download Manager(FDM)" as my default downloader of movies from websites that generated Magnet links. On clicking the magnet link the FDM is not opening by default, no action is seen. I've tried many options including the Support Centre of FDM from where I was advised to visit my browser support. I have used Firefox for 14 years, let me know where I'm wrong.

My tab groups just got lost. I didn't do anything to remove them. How can i restore them?

When this feature appeared, it was not available to me and I included it in about:config, but them disappeared when this feature reached me officially.

I wanted to create two profiles to separate my work and personal contacts. For security reasons, I also wanted to set up one account as the secondary email address for the other (I only have these two email addresses). Account A is a Gmail account and Account B is an enterprise domain account. Account B had the Gmail account as the 'secondary email'. However, when I try to access the Account A profile, I receive a red square message saying 'Primary account email required for sign-in' after entering the password. Perhaps I did something wrong, but... How can I access my Account A profile? Account B no longer has a secondary email address to prevent further problems.

Hello Mozilla Community, Every time I want to log in to Samsung.com and eu.community.samsung.com/t5/deutsch/ct-p/de, I have to re-enter my email address. The password is suggested. I'm not asked if I want to save my login credentials, but I'm asked for it on all other websites. I prefer Firefox to EDGE (it's suggested in EDGE). It's like this on Windows 10 and on my other computer with Windows 11 (both 64-bit and both up to date). What do I have to do so that Firefox also suggests the email address on these sites (asking whether it should be saved)? And I use a translation program from German to English. Again, thank you in advance for your reply.

I have downloaded Duolingo on my Windows 11 laptop. When I try to run it, it says that it can not open it because it can't find Microsoft Edge. This is the latest version of the app. I can't find anywhere to change the Duolingo default browser. I have Firefox set as MY default browser in windows settings. I also have AVG Secure Browser installed on my laptop but seldom use it. I donot have MS Edge installed on any of my computers. Can anyone help me find a solution to this problem? What other information do you need?

After last upgrade, I restored an earlier profile to RESTORE my bookmarks and passwords.

I set my old profile as DEFAULT.

YET NOW, I have the highly annoying problem that when I open a link from my email, it opens in the profile-release new version.... I then again do not have access to passwords and bookmarks.

Mozilla Firefox should address these issues, rather than have MILLIONS of people individually trying to fix the problems that the latest release caused.

I'm afraid to close my browser windows or even restart PC like I often do; I'm afraid I'll have to waste another 6 hours (like yesterday) trying to restore the profile, bookmarks and passwords.

The Firefox version I used before was Mac version 136.0 After I updated to the latest version, I found that the fonts of the browser's tab bar, search box, and bookmarks became significantly larger. How can I change the font size?
