I recently updated to windows 11 and now when I open firefox my tabs are no longer there. I have repeatedly gone into settings and checked "open previous windows and tabs". Dosnt work. Still opens to a blank browser with only one 'new tab' present. Most troublesome since having my tabs for my email addresses, calender and google keep come up each time is a big time saver for me. Ive been doing this for years and thanked mozilla silently many times for this. But now Whats Up???

Hope someone can help. I see it was posted last year but none of the response makes sense/applies to me.

Lorsque je demande l'ouverture d'une nouvelle fenêtre, , puis d'un nouvel onglet, j'obtiens une fenêtre nommée nouvel onglet; puis en cliquant sur la croix + à droite j'ai une fenêtre "site non installé OVH Cloud. Comment supprimer cette fenêtre?

If I view sites in any other browser I can view signup forms, Facebook/social media widgets on sites, etc. But they are not there when using Firefox. I do clear cache at all levels.

Firefox stopped working today. Every time I launch it, it responds with: "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window."

I launched Task Manager and killed the active processes, relaunched ff - did not resolve the issue.

I have uninstalled and reinstalled ff multiple times - did not resolve the issue.

I have removed the lock as per here: https://support.mozilla.org/en-US/kb/firefox-already-running-not-responding#:~:text=Right%2Dclick%20on%20an%20empty,it)%20and%20click%20End%20Process.

I have verified the access rights as per here: https://www.minitool.com/news/fix-firefox-is-already-running-but-is-not-responding.html

I have completely removed all the mozilla entries from both Program Files AND in the registry, then reinstalled. did not resolve the issue. registry instructions from here: https://www.reddit.com/r/firefox/comments/s9lguc/how_to_completely_uninstall_firefox/

I have tried to delete existing profiles AND create a new profile but I always get an error: "An unexpected error has prevented your changes from being saved." https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles#w_start-the-profile-manager-when-firefox-is-closed

I'm out of things to try. Hate to abandon Firefox but I'm at the end of my capabilities.

Recently updated to version 105.0.1 and I've started to have problems with Twitch. I'm unable to login and keep getting the message: "Something went wrong. Please try again." so I cleared the cookies/site data. Still unable to login. I know this isn't an error with my account as I can login via Chrome with no issues. Then I tried downgrading to the previous version 104.0.2 and had no issues with Twitch. Most likely, this new version is creating an error with the Twitch site. Hopefully new updates will address this issue - in the meantime, hoping someone has a solution.

Version 105 did not install and get my accounts and passwords from the previous version? This is not a good update! And your help does not HELP!

Why did the Ubuntu update delete all of Firefox (I will also ask on Ubuntu forum)?

checking box within a Tab on yahoo mail will immediately open that entry and then freeze further operation until the screen is shut down. This happens on my wife's HP lap top i5 Pavilion 4.00 ram. ie: inbox tab will show a number of email - a dozen or so - followed by grey empty areas. The tab indicates 100+ total in inbox. Selecting one box opens the email but locks up any activity on that email & must be shut down to exit. The identical situation happens when I access my email on her machine. She is using Firefox 105.0.1 HOWEVER, on my machine, HP desktop AMD A8 8.00 Ram, both email addresses do not lock up, multiple boxes can be checked and work as expected. My desk top uses Firefox 104.4 This began happening within the past couple of weeks and I can not debug the situation. Any pointers ??

I installed the new Windows 11 update now when I exit out of firefox "X" the next time I go to open and error tells me that firefox is running (it's not showing open and running) and I have to close.

I installed mozilla today and I looked in to my settings and found this message "Your browser is being managed by your organization."

I am not part of any organization since this is my home pc.

I checked the forums but i couldn't solve this.

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox and HKEY_CURRENT_USER\SOFTWARE\Policies\Mozilla\Firefox doesn't exist for me and i don't use avast.

On about:policies it shows "Certificates-ImportEnterpriseRoots-true"

What is this ImportEnterpriseRoots thing?

I'm using a laptop with windows 11.

Can anyone help?

on a MAC LAPTOP....Mozilla Browser updated yesterday... missing all logins/passwords...sync is on... how can I retrieve the old mozilla for logins?

HELP PLEASE..!!!

Hello my firefox instantly crashes whenever i try to open it and the crash message window pretty sure it is also closes instantly I dont think I litteraly cannot use the browser at all because of this. I am on a freshly reset pc aswell so i have no clue what it could be

Before the latest update Firefox worked with Windscribe doublehop. But after the update Firefox works only with a single hop, ie. Windscribe on PC only, and this is a privacy issue. Very poor and very disappointed. Very likely will have to change browser.

After upgrading to Windows 11 22H2, I cannot log into Canal + Online. The Canal + website works normally only when you try to login to it it crashes. Cookies cleaned, firefox reinstalled. Another browser is not a problem. I logged on the second laptop also on firefox with Windows 11 22H2 and the same error.

Hi,

I used the refresh Firefox option yesterday and after that have been unable to configure Firefox 105.0.2 to use my favorite external editor (notepad++). My old instructions for setting this up seem not to work anymore. Are there instructions for setting the view_source options that work in current Firefox versions?

I've used notepad++ to view and edit my HTML pages in Firefox for many years. This is a really big deal for me. Thanks in advance

just downloaded firefox version 105.0.3 using aol email. i open a message ok click on a link in message and it just goes to a blank page and just hangs. I'm using windows 7 on a dell laptop. this happens in many different messages. never did work..

I just made the switch from Chrome to Firefox, and I'm still trying to understand the small differences that exist between the 2 browsers.

While on Twitter, what I usually do is middle-click with my mouse on a Tweet to a new tab that I want to look into later, then continue scrolling down my timeline, then check out the Tweets I opened in the new tab(s). However, when I try to do the same thing on Firefox, it automatically opens the new tab. Because of how Twitter works, this also reloads the Home page when I opened it up, so I just lose anything I was just looking at when I opened the Tweet in a new tab.

What can I do differently here?

Hello so i've recently wanted to start using firefox as my browser but every time i try to open firefox the window where its supposed to be appears for a few milliseconds then just dissapears like it never opened before
