Firefox will not load--

by Cletus29 Oct 5, 2006 8:26AM PDT

I have been running Firefox for several months with no problems on this win98SE, but suddenly the program will not load. The error msg is ?FIREFOX caused an invalid page fault in module JAR50.DLL at 0167:6001134d.? This dll is part of the Firefox program.

I decided to remove Firefox and reinstall, but I cannot remove the program from Add/delete in control panel or by using the uninstall file in Firefox. Tried Ad/Remove Pro also with no luck.

I have run out of ideas---can anyone help?

Thanks

Manual deletion...
by John.Wilkinson Oct 5, 2006 8:34AM PDT

I would go to C:\Program Files and delete the Mozilla/Firefox folder then download a fresh copy of Firefox and install it. All of your bookmarks, settings, and extensions are stored separately and will remain intact, so this will simply address the corrupted file(s).

Hope this helps,
John

I considered this approach, but---

was afraid I would foul up the registry. Do you think it it would be safe to do?

It's safe...

Deleting those files won't affect the registry in any way, nor will it result in other problems with your system. Once you reinstall Firefox everything should be as it was before, less the crippling error.

I will continued to troubleshoot.

Many thanks for your help---I learned something.

Next stop...
by John.Wilkinson Oct 5, 2006 10:40PM PDT

The next stop on this route would be to delete the Firefox folder again and reinstall followed by launching Firefox (Safe Mode) from the folder Firefox created in the Start Menu. That disables all installed extensions and themes and will help determine if one of them is the source of the corruption.

If the problem still continues after that then you'll need to continue to the end of the line, where it is suggested that you repair Firefox, deleting your Firefox profile and starting clean. Unless the corruption is being caused by some outside force this will resolve it.

All aboard! Happy

I had same problem!
by shaner7575 Oct 6, 2006 4:11AM PDT

I have windows 98SE and had the same error message.
My son has windows xp, and firefox wouldn't load at all, until I used safe mode. I noticed that after updating customize google is when the problem started, so that's the first extension I uninstalled in my son's computer. Now everything is fine, since I'm using firefox right now.
I'm going to start up my old standby, and uninstall the customize google and see what happens.
Just wondered in here and noticed this thread, so thought I'd give you my 2 cents worth.
Hope you have it fixed by now!!

Not fixed yet----
by Cletus29 Oct 6, 2006 10:37AM PDT

but I will have another try at it using the new suggestions.

I will report back my success---or failure.

Many thanks--

Firefox is up and running again---
by Cletus29 Oct 7, 2006 8:30AM PDT

Reinstalling and then booting to safe mode and starting the program there, with with none of the options checked, did the trick.

Many thanks---I would never have thought of that procedure.
