I-Firefox Community Forum

We use firefox for accessing several websites for our town. We are getting an error message : "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." I have tried closing the open window and I restarted the computer several times, with the same result on the message. I am running Windows 11.

Firefox launch opens /home/pdl/Documents/Browsers/Firefox/chrome as a new tab, I have set the setting "Open previous windows and tabs" on and off, I prefer this setting to be enabled, my OS is LMDE 6 and Firefox is the flatpak install version 137.0.2 (64-bit), I have also tried the system install and deleted all Firefox in between installs or should I say I think I did, please this is driving me nuts, even with me logged out of Sync this happens.

Thanks

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!

Have tried suggestions from other strings. Will not open in any mode on my Mac mini so cannot even uninstall. Continue to get message that It is trying to install a new helper tool but will not install or open. Restart did not work, shut down and restart did not work, “safe mode” with shift key or option key does not work.

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?

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

Was in the midst of a Quickbooks data download and Firefox browser disappeared and Windows no longer lists it in programs save for "Firefox Private Browsing" which triggers an "cannot find" error message when I try launching.

Long time user and never had trouble.

There were a few error messages from anti-virus software during the transaction - which I assumed were due to interfacing with someone online doing the data transfer so I ignored them. So it could be related to that.

Firefox was my default browser, on two places on my desktop, now it is gone.

During the QB download process, I had to switch browsers and use Chrome to find my email etc.

I am fine with just uploading Firefox again, though I assume it means I will lose my open tabs and possibly any memorized passwords etc.

Please advise - Thanks

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.
