I refreshed Firefox, and could not reopen due to missing XPCOM file. Now what?
Currently, I'm using IE to get online, (Forgot about chrome).
I'm running an HP laptop with Windows 7 premium home edition. I was cleaning up old files, and decided to refresh Firefox. I clicked on the button, and a few minutes later, the process had completed. However, when I opened the Firefox page, all of the tabs looked like an IE browser page, none of my bookmarks were visible, I couldn't locate anything familiar re tools, etc, and decided to restore to a previous point.
That began the problems.
I restored to a safe point, and then windows 7 would not restart. Windows went through with a diagnostics test, and after completing, shut down. I restarted the laptop. Surprisingly it started. I tried to open Firefox, and a popup said it 'couldn't load XPCOM.'
I decided to restore to an earlier date, and this time, restore did not complete. I ran diagnostics again, completed and machine shut down. I restarted laptop, and windows WAS restored to that earlier date.
However, I am unable to open Firefox.
At this time, I have no Firefox browser, which means I do not have access to anything re bookmarks, etc that would be avail on the tool bar.
What else can I do?

I don't know what else you can do besides starting over on Firefox. But you can still save your bookmarks, saved websites, etc, but it will delete your add-ons and extensions. Go to this site to learn more: https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-settings
By clicking "Refresh Firefox", it removes Firefox from your computer and reinstalls it, but it also keeps your bookmarks and saved info. If that does not work, which it should, I would go on the computer to Control Panel, and click "uninstall a program" (blue link under Programs section). Find "Mozilla Firefox" and "Mozilla Maintenance Service" and uninstall. Then go to your "Program Files (x86)" and find the "Mozilla Firefox" and "Mozilla Maintenance Service" folders and delete those manually. I would empty the recycling bin, and maybe restart the computer for good measure. Then download Firefox again. Test the browser, if it works, put your "old firefox data" into the Mozilla Firefox folder to migrate your saved info. Hope that helps!

This usually happens because of a failed Firefox update that left you with a mixture of old and updated files in the Firefox program folder.
Do a clean reinstall and delete the Firefox program folder before (re)installing a fresh copy of the current Firefox release.
- Download the Firefox installer and save the file to the desktop

If possible uninstall your current Firefox version to cleanup the Windows registry and settings in security software.
- Do NOT remove "personal data" when you uninstall your current Firefox version, because this will remove all profile folders and you lose personal data like bookmarks and passwords including data in profiles created by other Firefox versions.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
- (32 bit Windows) "C:\Program Files\Mozilla Firefox\"
- (64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"
- It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

Your personal data like bookmarks is stored in the Firefox profile folder, so you won't lose personal data when you uninstall and (re)install or update Firefox, but make sure NOT to remove personal data when you uninstall Firefox as that will remove all Firefox profile folders and you lose your personal data.
