hi, this file isn't part of firefox. it's looking like a radnomized filename and there are 0 results for it on google which should be a big red flag. please scan your system for malware with multiple different tools like the free version of malwarebytes and the eset online scanner: https://www.malwarebytes.com/mwb-download/ https://www.eset.com/int/home/online-scanner/

thanks for reply, but system is clean! (i checked it - nothing!) after another try to start FF - event log show another file!
and one more think - 62.0.x - everything OK, only after upgrade to 63.0.x - crashed!
how did you check - did you use some different security tools as recommended? please also try to locate the incriminated file on your disk an upload it to virustotal.com which will scan it with a few dozen engines...

check system by cisco amp, microsofr SE, eset online scanner - result - no viruses.
I sad - 62.0.x - everything OK, 63.0.x - on win7 x32 crashing, on win7 x64 - ok, win10 x64 - ok!
virus total - https://www.virustotal.com/#/file/e242f8ec682295c4a8556199072348c2cea4e0f69775d67c458d4adbfcb04c0a/detection
maybe developers do something wrong?
please upload the "a_kerflzjl.dll" file (or whatever it's called now when it's randomly changing names) to virustotal, not the firefox setup file (we already know that it is clean).

Hi! Any ideas for fix issue on Windows 7 x32 after upgrade to 63.0.x?
i still think the symptoms point towards malware on the system unfortunately

I found problem - on clean system I installed firefox (win7 x32) after that installed Cisco AMP!!! And this antivirus deleted this dll file from c:\windows\system32\***.dll and firefox crashed. Question - why firefox create this file? On x64 (win7 and win10) this dll file FF doesn't create!
