I have a user at my job that installed the latest Firefox update (13324.11.21) through our MDM. After installing this update she cannot launch Firefox. When attempting to launch she receives a request for a username and password to install a Helper Tool. She is an admin on her machine and enters her credentials. The message closes and nothing happens. When attempting to launch again the same thing happens. This is not happening with our other 100 Macs who have the same Firefox version and others who have the same OS.

Is anyone able to tell me why this is happening or how to fix? Any assistance is very much appreciated.

The below troubleshooting steps have been done:

Uninstalled and reinstalled Firefox

Updated the OS to 15.0.1

Disabled the Master Password on Firefox through a Mac Profile

Checked if there was a Firefox file under /Library/PrivlegedHelperTools

Granted Full Disk Access to Firefox under System Settings

Issue with high disk usage - \Mozilla\xul.dll after wake from hibernate

Win7x64p, FF 115.18.0esr (64-bit) When I power on my Dell E6440 from hibernate (& restart?), with or without some small portable apps running -Total Commander, notepad. I have to wait (sometimes 5 minutes or more) before I can use without significant lag. HDD LED full-on. If I start up FF while disk usage is very high, sometimes 1 core of CPU gets stuck at 100%. Sleep & wake resets this. Watching in Resource Monitor \Mozilla\xul.dll using high disk B/sec & HDD LED full on, when HDD LED returns normal xul.dll disk read activity drops to 0 or near.

Is a FF service/process reading its stored data?(via xul.dll) or something. Looking for any ideas to troubleshoot.

I'm not having any issues with FireFox running, just this process making PC unusable after wake-up. Thanks

Hi, I am in Australia and over recent months I have had trouble fully loading websites on FireFox. I have used FireFox on my laptop for many years but this issue has just emerged. I can open the same websites on Chrome and they open as fully functional ie, links are live, sign in options are available. Is there a reason why this is happening? The websites I tried to open on FireFox are important sites for me and I use them regularly. Is there something in settings that I need to change? I do not want to stop using FIreFox but I will have to change if I cannot access these websites. I have attached screen shots of one particular website on FireFox and Google Chrome. Kind regards Narelle

I got a password manager app but ended up uninstalling it. In the process, the normal insertion of my user name and password on accounts I use no longer happened. The information is still in my password file on my iMac, but when I access, for example, my bank, I have to enter my user name and password by hand. Before I tried the password manager (Roboform), there was no problem.
