Sorry to hear about the crashes and thank you for the report ID. That particular report indicates Firefox was not able to get enough memory from Windows, since memory was 92% full. I don't think we can solve that, Firefox does tend to crash more when memory is over 80% full.

The XPCOM error usually indicates damage to the program folder. For that, I suggest:

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, corrupted, 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 42.0 from https://www.mozilla.org/firefox/all/ to a convenient location. (Scroll down to your preferred language.)

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

(C) Rename just the current program folder, either:

(64-bit Windows folder names)

C:\Program Files (x86)\Mozilla Firefox

to

C:\Program Files (x86)\OldFirefox

(32-bit Windows folder names)

C:\Program Files\Mozilla Firefox

to

C:\Program Files\OldFirefox

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

Will Firefox start and run more normally?

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

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

Otherwise, there's no reason to keep the old folder except research/curiosity.

Thanks for your help, but I was not having any difficulty with Firefox crashing. that only started happening after I updated add-ons, and it has NEVER started since. It's using no more memory now than it would have been that day, two weeks ago, or two months ago.

I'm still not sure how memory ties into getting a new XPCOM to load.

Anyway, I read about a "fix" on line that sort-of works. I added another user profile to my computer that is not the administrator. then I downloaded and installed Firefox there and it works perfectly!

Now, I can't believe Firefox wants to re-establish and re-install all of my preferences, favorites, and programs--a month of work!--and not log myself in as the administrator--so that I can use Firefox.

Are you SURE there isn't something I can do?

Thanks once again for your help!

Thanks for your help, but it didn't do me much good, I'm afraid.

So the current issue is that you need to transfer at least your bookmarks from your old Firefox profile folder to your new Firefox profile folder. Saved passwords and most preferences also can be copied over. But it's usually safer not to try to copy over add-ons if you can tolerate reinstalling them from their actual sources. It's a bit of a project.

You'll need to open both profile folders in separate windows, and close Firefox while copying files. This article describes what the various available files are: Recovering important data from an old profile.

Oh wait, you don't really want to use a whole new Windows user profile.

So going back to your problem.

Why did you mention XPCOM? Did you get an XPCOM error trying to start Firefox? If you got an XPCOM error trying to start Firefox, please follow my earlier suggestion for a Clean Reinstall.

The closest I ever got to having Firefox installed was after using a system restore that took my system back to 5 days before it I updated those Silverlight and Adobe add-ons upon Firefox's request. Once the system was restored to that restore point, Firefox was there and didn't open because "XPCOM couldn't be loaded" or the like. I thought yet another clean re-install would get me a "loadable" XPCOM, but even if it did, Firefox still crashes before starting every single time--when I am logged in as the administrator. That single XPCOM message was the only hiccup in a continual string of crashes-before-start-up for two weeks now. Any ideas?

Using a System Restore is never safe and should only be considered as a last resort.

Using System Restore can cause your Firefox installation to get corrupted because only white-listed files are restored, so always be cautious with using System Restore.

• You may lose data in the Firefox profile folder like .js and .ini files
• You may need to reinstall affected software

So you should definitely do a clean reinstall and delete the Firefox program folder.

I think it's part of this email address: newtabtools@darktrojan.net.

We can learn a lot more from the online version of the crash report -- more details about what was happening at the time, related bug reports, comments from other users with the same problem. Can you retrieve any submitted crash report IDs as described in the article I linked to before?

Thank you for the report ID. That one is an "out of memory" fault. Firefox apparently requested a small chunk of 152 contiguous bytes of memory and was declined. System memory was about 83% full, which starts to get borderline for Firefox.

There is a bug report on file linking this (or a similar) problem to some of the operations listed in the crashing thread:

Row 10: nsPermissionManager::InitDB(bool)

Row 8: nsNavHistoryContainerResultNode::SetContainerOpen(bool)

Comments in the bug speculate that perhaps some changes in Firefox 42 involving a change of format to one or both of these databases causes excessive memory use just after installation. Did you just update to Firefox 42, or have you been running it for a while?

One possibility would be to take one of the two databases out of the equation.

• places.sqlite contains your history and bookmarks. If deleted, Firefox will start a new one by importing from your last bookmark backup.

• permissions.sqlite contains mostly site-specific permissions for cookies (allow/block), popup windows, and plugins (allow/ask/block) -- other information in here is accumulated over time automatically and probably you don't care about it.

I'm not sure you want to lose either of those...

I decided to import all of my Firefox preferences, bookmarks, etc., into Chrome. Then I uninstalled Firefox, deleted my user preferences, reinstalled it, and imported them back from Chrome--bam! Done. It's working as well as ever! Apparently that much memory isn't as big a problem as one might think--Firefox never had a problem with it before and isn't now. Thanks for your help!
