Firefox no longer starts up. It crashes and stops responding on MAC Monterey 12.7.4 This is as far forward as it will go on this old mac. Everything worked fine yesterday, start up today and no go. I removed the profile and attempted to restart. No joy. So I downloaded a fresh copy and installed it over the old version. No joy. Cannot access profile manager. Removed version and fresh install, still no joy. How to I get it to launch, then How do I recover data from old profile?

Videos won't load in previously enjoyed timeframe or indeed et all sometimes. timeouts when loading pages. speeds are like 15 years ago even in troubleshoot mode and after refresh. when can I expect improvement?

How do i get the search URLs from the previous browser to pop up log-ins automatically to favorite sites when beginning to type in the URL ? Like using an old Social Media links - Rumble or Facebook .login ; or an Ebay log in a gmail log in?

Do i need to restart the computer ?

Hello! After being away from my PC for a few days I tried to open firefox and got this error:

'Firefox is al actief, maar reageert niet. Het oude Firefox-proces moet worden afgesloten om een nieuw venster te openen' aka 'Firefox is already running but not responding. The old Firefox process must be closed to open a new window'

I deleted the application in windows settings and then redownloaded it. The problem persists. What can I do?

Hi,

Dunno if this is by design, but a lot of installers don't play well when installed from standard user account with elevated privieleges. Firefox installer on Windows 10, when ran from GUI or admin PowerShell, accesses AppData fodler under standard user account that started the elevated process. Thus, it's not possible to install it if admin account doesn't have access to user folder, as on my system it doesn't for security reasons.

It's a minor inconvenience to need to explicitly log into admin account and do it there. But as this is a disease among installers I'd rather have them play well with normal security.

You may disagree here, and I understand if you do. Just pointing it out.

I've been having this annoying popup about XULRunner encountering an error. From what I've read, XULRunner is a legacy integration with Firefox. Sure enough, I see Mozilla Firefox installed. But un-installing it doesn't help. Soon, it is re-installed, and the error comes back. I have a feeling that some application is using XULRunner and Firefox as a component, but I don't know what it could be. Is there any way to find out, and stop that application from installing Firefox and XULRunner? Or at least getting its problem fixed?
