Experiencing frequent crashes in Firefox


For the past two months or so, I've been experiencing intermittent (but frequent enough) Firefox crashes. I could be browsing from anywhere between an hour to five minutes before experiencing a random crash. This is particularly disruptive for me because I tend to upload large files to Youtube, soundcloud and tumblr several times a week as part of my college course work and these crashes make that impossible. Initially I thought it was an issue with Firefox 18, so I re-installed version 17. This didn't solve the problem. So after another few weeks, I couldn't tolerate it anymore. Suspecting it was malware (just a hunch from past experiences, I'm tech savvy enough but have no real knowledge coding unfortunately) I formatted my PC and installed a fresh OS. With my system, drivers, and security up to date I installed Firefox and the crashes persisted. Even with recent upgrade to 19 this problem has persisted. Add-on wise, I make judicious use of no-script and Ad Block Plus (in conjunction with Avira & Malwarebytes), so I feel it's pretty unlikely the result of malware, though obviously I wouldn't be asking for help if I could figure this out myself.

Today I reset firefox, removing all Add-ons. Still got crashes. I ran it in safe mode, still got crashes. All the support documentation online leads me here and I'm kind of at wits end with this problem

Any help with this matter would be greatly, greatly appreciated. Here's some crash reports, most recent is first:




Cheers guys.

You have a virus still, erijbbfs.dll. Search your computer for the offending .dll, and delete it. It's most likely hidden, so view hidden files and folders. http://windows.microsoft.com/en-US/windows7/Show-hidden-files

Then, turn the .dll off from starting up with your computer. http://www.netsquirrel.com/msconfig/msconfig_xp.html (Go to startup and uncheck this .dll)

Question owner

Hi Jaya, thanks for the speedy reply.

I've tired searching for the file numerous times, disabled hidden files & folders, rebooted into safe mode and searched again, run multiple virus scans but to no avail. I just can't seem to find erijbbfs.dll anywhere on my system.

Any suggestions on how I should proceed?

Thanks, Matt
