Hello!

I downloaded the latest version of Firefox for Windows XP but it always crashes on start-up. Mozilla Crash Reporter appears. I am not able to start Firefox in safe mode.

My latest crash ids are bp-9fdcf812-70e4-4025-97b1-4c7592130430, and bp-74c78b9f-ad72-446e-aa0a-d8aef2130429.

I immensely appreciate any assistance you are able to provide. Thank You!

hello, from the crash report you've submitted it seems like the crash might be adware/malware related. the file on your pc causing the crash is named datamngr.dll.

first, please go to the windows control panel / programs section and see if you have any toolbars, imesh, MediaBar, data manager or other similar suspicious programs installed - if so remove them...

afterwards please run a full scan of your system with different tools like the free version of malwarebytes, adwcleaner & microsoft safety scanner.

Thank you philipp!

After I removed that datamngr file from my system, the browser worked. Thank you so much for your help.

All the Best to You!
