The Firefox stable desktop taskbar shortcut issue unresolved for many months. Every time clicking on the Firefox taskbar/start shortcut is non responsive or it gives the error class not registered. Firefox nighly/developer do not have this issue. Fujitsu laptop, Widows 11 lates upgrades. Please fix.

After updating my Apple operating system to Soia equoia 15.3.2 Firefox will not open in any other accounts other than the administrators. A prompt appears stating Firefox is trying to install a new helper tool. When myself as administrator logs in to install it, it will not do anything and the application does not open. Firefox does work fine when I have my administrator account logged into. Firefox has never had a problem on this computer until the update to 15.3.2 occurred.

I've been a Firefox user for ages but in the last week I haven't been able to use it at all. Every time I launch the desktop browser it gives me a blank page. I can type in addresses but they never take me anywhere. No google. Can't access settings. Nothing. I've tried seemingly everything. Safe mode. Administrator. Deleted everything and installer at least 5 times to try and start from scratch to no avail. Tried Revo. Tried multiple anti-malware cleans. System updates. Tried using older versions of Firefox. Everything short of a factory reset on the whole desktop which I'm really trying to avoid. I've checked every Reddit thread and forum post I could get my hands on and nothing is working. Does anyone know how to get Firefox working again? I've tried other browsers and hate them I would really like to keep using FF if I can. Picture shows what the app has looked like every time I boot it up or try to search anything for the past week.

Hi, We are using Horizon VDI terminal server. Firefox is installed on these servers. Some users get Firefox is already running but is not responding error. Ending Firefox via task manager does not work. I log off the user and have them log in again, but it does not work.

When I check, I see that the user's profile file cannot be created on any terminal server.

Is there a solution to this problem?

The shortcut icons on my home screen used to direct me to frequently used websites. Now shortcuts are showing up linking to to recently used websites, pushing off or even removing the ones recently used. I can't find anything in settings to remedy the problem so I have disabled home screen shortcuts. Do you have a patch to correct the problem?

My firefox app on my windows will not start. I have removed and reloaded several times. Sometimes it works but as soon as I turn off my computer and turn it on later, it will not start

Firefox will not open in my Windows 11 desktop; is Microsoft playing games with non-Microsoft applications or is there a problem with my browser? fresh install does not help! last week I had to reset Windows 11 because nothing would open in my desktop...... reloading all my application is not near the top of my wish list having already done it twice! all the Microsoft stuff opens fine; even my copy of Office 2003?

There is no Japanese in the language to which the website is translated. It is understandable that Chinese is available in the Asian region. However, we would like to ask why there is Indonesian, Vietnamese and Korean, but no Japanese.

Hallo, ich habe am Mittwoch 26.02. das Programm PC-Cleaner gestartet und unter der Funktin "Optimieren" WINDOWS - Reparaturprüfung aktiviert. Das Programm lief ein paar Minuten, dann erfolgte ein Neustart, danach wartete ich sehr lange und es passierte nichts! Ich habe nach ca 1 - 1,5 Std. die Task abgebrochen! Wollte dann meinen Browser Firefox öffnen, was nicht mehr ging!!! ...genau so war es mit PC-Cleaner! Ich habe mich dann an den PC-Cleaner Support gewandt aber über den Chat nicht viel erreichen können! Ich wollte das gerne telefonisch klären - war aber auch nicht möglich! Nun habe ich auf die Rückmeldung eines Technikers gewartet! Mittlerweile konnte ich das Programm PC- Cleaner erfolgreich löschen und neu installieren! Aber mein Browswer funktioniert noch immer nicht trotz mehrfacher Neuinstallation! Ich kann Firefox öffnen allerdings nur als Admin, sehe dann meine Lesezeichen, kann aber keine Seite öffnen! Bitte info - Vielen Dank!

For about one week (or more) results of my questions or other input have resulted in suggestions/sites in Spanish. Yes, I live in South America, but I do not speak or read Spanish. I have chosen English as my preferred language. What's up?
