If you can't get Firefox to open, you will have to do this the hard way. Open the file browser / explorer on your computer. Note: You may have to enable Show Hidden Folders / Files. Enter this in the address bar;

Windows: %APPDATA%\Mozilla\Firefox\Crash Reports\submitted Win 7/Vista: C:\Users\<username>\AppData\Roaming\Mozilla\Firefox\Crash Reports\submitted Win XP/2000: C:\Documents and Settings\<username>\Application Data\Mozilla\Firefox\Crash Reports\submitted

FredMcD, Thanks a lot of your response! I thought in safe mode hardware acceleration is disabled. So, not sure how graphics drivers are causing a problem. Still, I am trying to see if there are any graphics driver updates.

Nothing was flagged

I've called the big guys to help you. Good luck.

These startup crashes are hard to diagnose. There aren't a lot of clues as to why Firefox is halting. And the "EXCEPTION_ACCESS_VIOLATION_EXEC" is a little unusual in my limited experience.

In case your Firefox program files have become damaged, could you try this:

Clean Reinstall

We use this name, but it's not about removing your settings, it's about making sure the program files are clean (no inconsistent or alien code files). As described below, this process does not disturb your existing settings. Do NOT uninstall Firefox, that's not needed.

(A) Download a fresh installer for Firefox 46.0.1 from to a convenient location. (Scroll down to your preferred language.) For maximum plugin compatibility, choose the 32-bit version.

(B) Exit out of Firefox (if applicable).

(C) Rename the program folder as follows (usually only one of these is applicable to your system):

32-bit install on 64-bit Windows

C:\Program Files (x86)\Mozilla Firefox


C:\Program Files (x86)\OldFirefox

All other installations

C:\Program Files\Mozilla Firefox


C:\Program Files\OldFirefox

(D) Run the installer you downloaded in step (A). It should automatically connect to your existing settings.

Note: Some plugins may exist only in that OldFirefox folder. If something essential is missing, look in these folders:

  • \OldFirefox\Plugins
  • \OldFirefox\browser\plugins

Hopefully that will replace any corrupt files and let Firefox start normally.


I followed your steps and now firefox I am getting this error: "Your Firefox profile cannot be loaded. It may be missing or inaccessible."

When I looked at appdata\local\mozilla and appdata\roaming\mozilla they don't have any profile and my OldFirefox doesn't have it either. Did the reinstall overwrite/delete it? If so, it seems a severe error. Is there a way to recover Profiles?

I was able to start up firefox by renaming profiles.ini to profiles.ini.OLD under AppData\Roaming\Mozilla\Firefox

But as expected, the new firefox doesn't have any of my old passwords, history, etc. How do I get it back?

Type about:profiles<enter> in the address bar. How many profiles are listed?

The "Clean Reinstall" procedure should have no effect on existing profiles, so that's very puzzling. Earlier you said --

Firefox crashes everytime I try to open it (both normal and safe mode). Tried removing my Profiles folder under appdata\local\mozilla and appdata\roaming\mozilla. but still the same issue.

-- so did you move those somewhere else or what happened to them before you did the clean reinstall? Are they in the Recycle bin?

FredMcD, about:profiles shows me the latest profile created by the new FF install. No other profile is listed.

jscher2000, I ctrx-x, ctrl-v'd the earlier removed profiles to their respective directories under appdata\local\mozilla and appdata\roaming\mozilla. And then installed new FF. They're not in recycle bin.

So the old folders are not anywhere to be found at this point?

Could you try a global search of the C drive for places.sqlite to see whether there's anything in an unusual location? I assume you have Windows set to show hidden files and folders, but just in case:

I have show hidden files on. But couldn't find places.sqlite. So, did clean reinstall just remove my old profiles and created a new one? I think FF should have either warned while removing old profiles or should have created a backup. But, all in all doesn't look good :-( :-(

Something went wrong with the search: there is at least one places.sqlite file on the C drive, in your new profile. Could you try it again or try a different way? One less friendly way to search is using a command window:

(1) Type or paste cmd.exe into the Start menu search box and press Enter to launch a command window

(2) At the prompt, change to the root of C by typing cd \ and pressing Enter

(3) At the C:\> prompt, type dir places.sqlite /s and press Enter to run the search

(4) To copy a path from this window, right-click > Mark then select over the path and press Enter to copy it


I'm guessing you do not have any backups of your older Firefox data.

Did you ever set up a Firefox Sync account?

Windows may have created a backup of your old profile in a restore point. This program might work to let you extract it:

ah, that seems have found those profiles. Command line always helps! It seems that FF copied old profiles to Roaming\Mozilla\Profiles whereas the currently in use profiles are under Roaming\Mozilla\Firefox\Profiles. But don't know why FF installer chose to do that. May be due to some error? Does it log it somewhere?

So, how should i proceed from here? Just shutdown FF, copy the Profiles, restore profiles.ini.OLD and startup FF?

Firefox shouldn't have moved the profiles. It's difficult to get Firefox to deviate from its standard locations.

Yes, at this point, moving the folders back into the correct location and restoring the old profiles.ini file has a reasonable chance of working.
