Firefox Will No Longer Run After An Update

Have you tried uninstalling (leaving your profile intact) and reinstalling? I remember having this issue once and the cause was that some of the binaries didn't get updated.

 

Possibly an Add-on/Theme issue, try starting it from the Command line "Firefox -P" and using Safe Mode to get it running, or the same method and then creating a fresh Profile.

 

Correction: Firefox Safe Mode = hold Shift while clicking to start FX.

"Firefox -P" brings up the Profile Manager, as above.

Alt: try downloading a fresh copy and overwriting the 'bad' version, like a refresh install.

 

I've heard odd reports from this update, like it not working from the Start menu icon but it works fine from the Desktop icon, etc. Who knows what Mozilla did!

Anyway, pleased to see you're back in high efficiency mode again

"there are a significant number of user reports describing two new problems appearing in tandem after the firefox 44 update:
- failure to load any websites, the screen stays blank and stuck on "connecting...": https://gyazo.com/d643b08146fd7123519915496fe7f2c9
- a windows app crash report is displayed when firefox is closed:"

Kestrel: Glad it's working for you now and as you see you are/were not the only one.

 

I'd uninstall v44 and install v43.0.4 - https://download-installer.cdn.mozi...s/43.0.4/win32/en-US/Firefox Setup 43.0.4.exe

 

There should be an option when uninstalling to leave the FF profile and data intact.

 

Possibly an issue there with Flash's Protected Mode, I think that can be modified from the Control Panel icon, sometimes it's better not to use that mode.

An alt. would be to install Flash ESR version (might be disappearing from public access soon ): https://www.adobe.com/mena_en/products/flashplayer/distribution3.html this is the Flash version I've been using for 2-3 years now, Flash -related crashes/bugs have been exceptionally rare since using this. You'd need to use the Flash uninstaller to be sure of cleaning out all the old version before using this, live download: http://download.macromedia.com/get/flashplayer/current/support/uninstall_flash_player.exe

 

Keep checking the spam reports, click each one and follow the links once they're filled, there should be something useful there somewhere.

Maybe post up those links so that we can chase them up or email them to me if you don't want them outed in public

 

They will only address something they consider to be a program-related bug if it is reproducible by them.
What I would do as a troubleshooting step is to make a back up of the profile using something like Mozbackup
and save it somewhere safe. You can be extra careful and also do a copy and paste backup of the profile too.
I would then do a clean and total uninstall of Firefox - including the profile folder and every scrap and folder of Firefox, then restart the system, run CCleaner including the Registry cleaner, and then reinstall FX from a fresh download, and run it for a day or two with a clean empty profile. If the crashes continue then I suspect something else is causing the problem.

 

That's what I'm expecting to find out when following the trail from the report.

 

Should have read "crash reports" sorry. They will be auto debugged and there should be links added for similar reports, once there, it's often possible to filter down all the related reports to your FF version and there may be some bugzilla links to current bugs.causes, or the reports themselves might have some common 3rd party (usually) file/driver that could be the root cause.

 

Yes, there should be a link to it, usually a few hours after it's been uploaded. I think it's accessed via the (Alt) Help menu.

 

Just reading back in the thread I don't see confirmation that you uninstalled Fx 44, then restarted your system, and reinstalled Fx 44 from a fresh download. A standard program uninstall leaves the existing profile in tact. If you really haven't already tried that, as suggested in post #2, then you aren't losing anything by doing it now.

 

As far as the latest crop of startup crashes for FF44 shows, they're mostly (a very high %) EXCEPTION_ACCESS_VIOLATION

https://bugzilla.mozilla.org/show_bug.cgi?id=1243765

https://bugzilla.mozilla.org/show_bug.cgi?id=1243098

And others, plugin/flash triggered crashes are very low in number.

Some types seem to be very prevalent on nvidia GPUs, most are also present in FF45/46.

I'd suggest reverting to 43 or using the ESR version for a while, they can be installed into separate folders, if either of them shows the same startup crash, it must be something in the profile, possibly something new/changed by FF44.

 

You can stop that - you just need to change the preferences in Tools > Options > Advanced > Update
But that's not the same as uninstall v44, then reinstalling it FRESH. That's a simple troubleshooting step.

 

I saw no replies on whether you tried using a different profile, though many suggested that you do. My suggestion, is to use a different windows account and check if firefox works there. I may have missed it if you did. If it works there, then you know for a fact that your computer works fine, it is indeed something to do with your ff profile.

On another thought is to try aurora(beta) or minefield(bleeding edge(what I use)) to see if there is a difference. Lately one can run normal firefox, quit, then try minefield (example) with the same profile. If it fails, then the profile will have to be looked into.

 

I don't see that crash report shedding any useful light.
When you get time to do troubleshooting steps, you might make progress.
The first would be as suggested in posts #2, 27 and 30 - it's the most logical first step and takes barely 2-3 minutes.
If Fx 44 still doesn't then run smoothly, the next logical step is that in post #20

 

This is where the crash report links are:

 

I'd forgotten the exact details of how to access them (Pale Moon doesn't use that but crashes are rare to non-existant anyway).

Ok, difficult one (and this write up will be up to my usual amateur standard), no bugs listed in Bugzilla for this yet, according to the report summary page.

The crash signature is listed as RtlpLowFragHeapAllocFromContext | RtlAllocateHeap | _calloc_impl | _calloc_impl | __getlocaleinfo so it's some kind of memory allocation error digging deeper it's a Write error (EXCEPTION_ACCESS_VIOLATION_WRITE, I'd guess that *something* loading is trying to load into an area of memory that's already allocated to something else, or that it's denied access, perhaps for security reasons).

It's only reported from W7 systems, not restricted to any one language, judging by the comments, not restricted to any specific CPU /GPUarchitecture, first seen from the 16th of Jan. on the Beta 44, it also affects the 45/46 pre-release versions. Most crashes occur so soon that FF doesn't show in TaskMan.

I've scanned through a bunch of examples and there's no common 3rd party .dll that I can see. Some are also without any add-ons (FF Safe Mode?). Flash hasn't been loaded in any example I've seen.

The latter section of the error sig., getlocaleinfo, is a font reference. Fonts are a major target for exploits, each WU probably contains at least one font-related security patch (as does Flash), so there's a chance that this is triggered by a WU . It wouldn't surprise me to see that it's a 'bad' WU patch behind this.

I think I'd try downloading a fresh version of FF44 (or get 2, 1 US and 1 GB) and try an over the top install or two first. Failing that, copy your Profile data somewhere safe and then blow both FF and your profile away, reboot, install FF, load it once to check, then begin moving your Bookmarks and other stuff over a step at a time.

I don't think this is profile related, crashes are all virtually identical across 100+ machines/users.

 

Your data should be in a path similar to this: C:\Users\*User Name*\AppData\Roaming\Mozilla\Firefox\Profiles\*some random string*.default but look at the latest modified date if you have multiple profiles. (I'm sure you knew that anyway ^^ )

Important data is listed here: https://support.mozilla.org/en-US/k...profile#w_your-important-data-and-their-files but data from older profiles can be different: http://kb.mozillazine.org/Transferr...irefox#Suggested_profile_contents_to_transfer

 

I think my comments from #28 still stand, those linked Bugzilla discussions are from crashes that follow the same pattern as yours, but not quite identical. So try FF 43 or the current ESR 38.6 version: https://www.mozilla.org/en-US/firefox/organizations/all/ (plodr's everyday drive, I think).

Edit: yes, the Desktop is fine (no perms issues there ^^).

[Oh, my FF crashes that I listed earlier, I've just checked those and it looks like MS supplied nVidia drivers for W10 caused it (all other cases reported were from W8/8.1, I guess there aren't many W10 users with FF ESR + Flash ESR + nVidia cards!). Good thing I checked, I just installed W10 again here this morning, time for some updates ]

PaleMoon is good if you can use it. My machine with Firefox opens with a blank tab, usually, opens with my home page on occasion. Not a big deal but will probably do a fresh install in the near future. Which is something I always did until recently just started running the update as it was less time and trouble.
