Just after installation, and before going any further like adding the email account, ; google: Error 400 "the server cannot process the request because it is malformed. It should not be retried. That's all we know"

Same Problem as here but thread is archived: https://support.mozilla.org/en-US/questions/1465988

It has always worked great until now, but it seems that it no longer works with Firefox 147.0.1. Does anyone have any idea how to fix this?

Firefox has been my browser of choice for well over 20 years. I have a game I play every day (from FaceBook) just this week when I try to go to it on my laptop - it says your browser does not support WebGL. it has always opened using Firefox - this is a new error message. and the computer is only 5 months old and has Windows 11 on it. I do not want to switch to Google or Edge.

Like I said - opening the app worked every day up until about a week ago. What gives?

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

I have various shortcuts saved on the shortcut page comes up after logging in. Its set to 2 rows.. I use it every day. Used it this morning and working perfectly. Been out and when I came back the page is totally blank. I've tried sytem restore to 5th October but makes no difference. I use Windows 10 and read that Firefox are continuing to support Windows 10 I'm visually impaired and use a desktop PC with a large screen. I'm not PC techically knowledgeable. How do I restore my shortcuts or how do I re create them?

When I go to (seemingly) any Elsevier site, the browser tab immediately closes with no error or explanation. An example is this site:

Where are my shortcut tiles? I used CCleaner and they all disappeared and I can't get them back even though I make sure they were on and have 2 rows selected and restarted my computer since. This happened last week and still no sign of them. See pic for reference.

I am getting the following error message when using Firefox. The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem. I cannot see my bookmarks or add new ones. I followed the directions in articles about this problem and they did not. help. I decided to uninstall Firefox and l re-installed it from scratch and i still get the same error message.

Hi, Since the last update for Mozilla on the laptop (updated on 6/Oct/2025 - version 143.0.4 (64-bit)), all the shortcuts to websites in Firefox homepage I had pinned have disappeared. Also I can't add new shortcuts. I already have shortcuts enabled in Settings>Home>Firefox Home Content>Shortcuts.

Does anyone know how to solve this?

Kind regards.

Hi, ITVX is advising me yo update my browser but when I check Firefox it says it is up to date. As it is no browser, including Safari or Google Chrome seems to work. My computer is admittedly old (10.13.6) but should this mean that the browsers no longer work? Thank you in advance

When I open my Thunderbird I obtain information: "free link provider, Account is not properly configured".. The problem is I am not able to find a mistake, I have not changed anything in my configuration in recent months. What to do?
