On my windows 11 machine, Firefox requires me to re-log into my Mozilla account every few days (there is a yellow triangle on the Account extension, which when clicked, has me to log into my Mozilla account). I have tried several troubleshooting steps:

1) Create a new profile and set it as the default profile 2) Completely uninstall and reinstall Firefox using the steps in the following article, including removing user data. https://support.mozilla.org/en-US/kb/uninstall-firefox-from-your-computer

I'm using Firefox on a Mac and my iPhone and I don't experience this issue. I am logged into my account on both devices.

Thanks,

Paolo

After the update on the 14th, dark mode has gained weird stylistic choices that I cannot find a way to alter: namely, when closing a new tab, a white box with black font appears -as opposed to the previous darker toned grey/purple with white font. However as of writing this post, I notice that dark mode is not working on this webpage. Seeing as I have an extension enabled in addition to the basic dark mode selection in Firefox settings, I can only imagine that something was broken in the update. Please advise, the change is jarring.

Hi I was using TB 142 without problems. When upgrading to 143 ou 144.B4 I have problems sending mails to all users after some times. Usually the first mails are sent immediatly but after around 10 mails, I have very slow response (varies from 5 sec to more than 1 minute and sometimes timeout). Usually quitting TB solves the problem but this is very annoying. I went back to 140LTS and sems to have no longer this problem. This was tested on many diffrent networks. I am running under Fedora release 42

Thanks

Edition Windows 10 Enterprise Version 22H2 Installed on ‎03/‎25/‎2022 OS Build 19045.6332

Changing my OS is not an option for me; those decisions are made far, far away. I was allowed to use Firefox instead of Chrome. Sadly, I have to switch over to Chrome today in order to work.  :(

I have added a couple of screenshots.

I am moving over to Chrome to do some work.

Thanks for any help, B

Being able to tell anyone what's going on is almost impossible. I am thinking of deleting Firefox despite having been using it for years, a loyal customer who subscribes to your VPN. When I log in my pinned tabs do not open the web sites, I'm told I've got connection issues, I've removed the sites from tracking protection, X tells me that is an issue since it only started after the update before todays update. What is the point of pinned tabs if they don't open? If I can't resolve this issue I will use Chrome, All of my pinned sites open there I just have to get used to using another browser, I don't like Chrome very much but I'm pulling my hair out getting no joy from Firefox. There has to be a better way of contacting Firefox than spend ages online as though it's top secret! I'm using windows 11 24H2

Since last week, virtually anywhere i go using Firefox Android I get the attached cloud flare test for that site. I use a VPN but turning it off doesn't fix it. I have cleared the cache, reinstalled the browser, and the problem persists. Curiously, if I log out and use Firefox without logging in, it stops. Chrome, Brave and Edge don't do this. Thanks, Mike

I have WhatsApp Web pinned as a tab in Firefox, and other than that I also have a home page. Normally when I launched Firefox, only one window would open and it would have both the pinned whatsapp tab and the homepage in another tab.

Since today, now when I launch Firefox it opens two separate windows. One window only contains the pinned WhatsApp Web tab, and the other window contains the home page.

How can I make it so that when I launch Firefox only one window opens that contains both tabs? Please don't tell me this option has been inadvertently removed.... Thanks.
