Firefox won't open to do Reset-so uninstalled-no option to save profile!

Was getting error code of "can't load XPCOM ".
I thought it might be related to Norton since it had had problems twice in two weeks. Their tech support tried to help, but thinks it is a Firefox problem that was blocking Norton from being able to run. They were able to get Norton running, but not Firefox.
Since I couldn't open Firefox, I read that I should uninstall it. Did that. There was NO OPTION to "Save my Profile".
LEADING UP TO THIS - BACKGROUND PROBLEMS:
1. Was having "enterprise 1.1 seeming to throw annoying ad coupons on to my webpages. Saw this was a Firefox extension, so deleted it there, and in my Programs.
2. Was having an unwanted computer scanner program, which was bundled in with a software I ordered, kept trying to run scans. I didn't want that software in with the one I requested, but even though I checked off that I didn't want it, it installed anyway! I uninstalled that.
3. Then had an error request asking for a newer version of Java - I hadn't updated because I had been told that Java conflicts with Firefox).
A. Deleted old Java files from Programs.
B. Tried to download an install new Java. It wouldn't install correctly - error code 1601.
4. In the middle of all this Thursday (two days ago) MS Windows decided to do a 21 "windows update" thing - 21!!!! Took almost an hour.
TROUBLESHOOTING ----
WHAT HAS BEEN DONE TODAY: Norton tech support was able to run remote of Norton Power Eraser - and determined I DO NOT have a virus, or anything like that. (Good news!) Norton now is up and protecting computer again. He also kept running into MS popup messages saying that the " MS Installer is not working. "
STILL NOT WORKING: Firefox wasn't able to work - so deleted per Mozilla instructions.
QUESTIONS:
1. Any way to retrieve my FIrefox Profile - - like do a system restore to like a month ago or something?
2. What is this XP COM - and can I get it back if I need it? (is it needed?)
3. Is XP COM related to the MS Installer somehow?
I'm going to see if I can install FireFox now. But is there a way to get my Profile back ???? Will reinstalling Firefox fix this XPCOM thing - or is that something on my computer?
Thanks.

You will likely have to delete the Firefox program folder to recover from this XPCOM issue.
You can uninstall your current Firefox version to avoid issues with the registry.
Do a clean reinstall and delete the Firefox program folder before (re)installing a fresh copy of the current Firefox release.
*Download the full Firefox installer and save the file to the desktop<br>https://www.mozilla.org/en-US/firefox/all/
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.
*http://kb.mozillazine.org/Uninstalling_Firefox
Your bookmarks and other personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, 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.

Mac won't open pages in browsers. Chrome and Firefox won't open any pages - Safari will only open a selected few.

I've had some strange browser issues, with Conduit being added to Chrome (which I've tried to remove via the browser settings). Chrome will open my Gmail account but no ther pages. Firefox won't open anything. Safari opens a few pages (this forum thankfully) but is very selective.

I can use all browsers freely on other devices on home network (although Google.es has popped up on my iPhone now). I've run anti-virus software which hasn't picked up any problems. I've tried uninstalling Chrome and Firefox, but am unable to do so.

Firefox won't open, says profile may be missing or inaccessable, help pages not helpful

Firefox won't open at all. I get a "Profile Missing" window saying "it may be missing or inaccessable". This morning my connection quit mid-reset while it said it was going through everything and not to turn it off, since then it refuses to open. I tried everything I could think of. Tonight I managed to open an ancient IE and am here now, tried as much of the "Help Pages" suggestions as the site sent me to (none were what my computer has even though I'm running XP), but nothing fixed the problem. I removed Firefox and then re-installed, twice, it still won't open.
HELP!

I can find NO "profiles.ini" file anywhere. When I open the "default library" there are none of the files you say should be there.
I have tried a whole new download to update, it won't open because there is no profile.
I tried removing the program and re-downloading, still won't open.
I am not tech savvy enough to do much of the messing around you are suggesting. I need someone to help!
Also - this site is about the least "user friendly" site I've had to deal with in ages!
I should have been able to reply to the email, but you didn't allow that, too.
I need someone to somehow walk me through what to do. HELP!

Firefox won't open from the taskbar or desktop - what do I do

Firefox won't open. I uninstalled it and downloaded a new one. When I tried running it I was asked to close Firefox. As I did not have it running, I could't close it. All other programmes were closed. I also have the mozilla email which is still working.

Hello Gigi,
Thank you for providing so much detail about the issue you are experiencing with the iTunes app after upgrading to iOS 7.
The first thing I recommend is quitting and relaunching the applications on your iPhone:
Double-click the Home button.
Swipe left or right until you have located the app you wish to close.
Swipe the app up to close it.
You can find the full article here:
iOS: Force an app to close
http://support.apple.com/kb/ht5137
If you are still seeing the same issue after quitting and relaunching the iTunes app, I recommend restarting your phone and then resetting if it's still not working:
Restarting your device
Press and hold the Sleep/Wake button for a few seconds until the red "slide to power off" slider appears, and then slide the slider.
Press and hold the Sleep/Wake button until the Apple logo appears.
Note: Reset your device only if you are unable to restart it.
Resetting your device
Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.
You can find the full article here:
iPhone, iPad, iPod touch: Turning off and on (restarting) and resetting
http://support.apple.com/kb/ht1430
If the issue persists, the last thing I recommend is backing up and restoring your iPhone:

Tried to use Restore to return to pre-Firefox4 but now Firefox won't open and won't uninstall.

After trying to maneuver the new Firefox 4.0 for a while and giving up, I wanted to go back to the 3.6.1.6 version. I used the Restore feature to try to go back to the pre-Firefox 4.0 dowload. Since then, Firefox won't open. I have tried to uninstall Firefox 3.6.1.6, which is listed in my installed programs in the Control Panel, but it doesn't do anything. At this point I don't know what to do. I want to re-instate the 3.6.1.6 version on my computer. Thanks.

You're in a bit of a pickle here because you can't use System Restore to revert to 3.6.16. You probably now have version 1.9.2.x which is in part, files which were not removed when you installed FF4
What you can try and do is use System Resore to undo the last restoration which should take you back to 4.0 again. If that fails, see this article: http://kb.mozillazine.org/Uninstalling_firefox
If the undo restoration is successful, do the following to revert to 3.6.16
Go to [http://www.mozilla.com/en-US/firefox/all-older.html Download Firefox v3.6.16] and download it to the desktop. If necessary, download the file with IE8 and choose to save it to your desktop when you see the prompt.
Then go to Add/Remove Programs, scroll down to Mozilla Firefox and remove it, choosing to keep your bookmarks, customizations etc., (don't checkmark the box).
Then reboot and delete the folder called '''Mozilla Firefox''' at this location: ''C:\Program Files\Mozilla Firefox''
Finally run the installation file you downloaded to the desktop earlier.
Your bookmarks, customizations etc., are maintained in a different location and will become available to you again once you complete the installation.

Firefox won't open links from Mac Mail

Like everyone else Apple Mail links will not open in Firefox if it is already open. Clicking a link brings FF to the front but no page loads. Links work if FF is not open. Links work if command is pressed whilst clicking the link (opens in new tab in background).
Problem occurred after 32.0.2 update, it appeared to briefly resolve itself after 32.0.3 update, but stopped (I think) on next reboot.
Have monkeyed around for ages with different combinations of default browser and rebooting.
Will abandon FF and go back to Safari if this isn't sorted soon - shame.

I just want to link to these earlier threads so you don't get a lot of duplicate suggestions that have already been covered there:
* [https://support.mozilla.org/questions/1018542 Firefox won't open email links after update to version 32]
* [https://support.mozilla.org/questions/1023202 No tab opens when I click on a link if any Firefox window is already open]
(There might be others, but those are the ones I've seen)
Work is proceeding on [https://bugzilla.mozilla.org/show_bug.cgi?id=1017595 Bug #1017595 – Links from external applications sometimes fail to open when Firefox is hidden] but as you can tell from the title, this is focused on the problem of Firefox not coming out of hiding from the dock or coming out of hiding but not loading the page. If this also occurs when Firefox is not hidden at all, there may be a secondary issue. But hopefully solving the one will solve the other. Unfortunately, I don't know whether it will be in time for Firefox 33.

Try close all inactive apps
1. Double tap the home button to bring up the multi-tasking view
2. Swipe up on the screenshot of the app you want to exit.
3. The app will fly off the screen

Then it just sits there forever, spawning and killing new processes. Firefox never appears.
Any ideas?

In order to test the problem, I think my suggestion is better; at least as a first try. Without Firefox running and without ~/.mozilla; no misconfiguration should prevent Firefox to run. The options you suggest will try to disable any problematic configuration. It can be usefull if you need to start Firefox to fix a configuration problem; but as a firt try renaming the ~/.mozilla is better because you are sure that Firefox can't read anything that can hurt it. Only after having figured out that a bad ~/.mozilla is the cause of the problem, we can try to fix the configuration (or restart with a new configuration).

Firefox won't open after re-installing and can't remove from control panel. What do I do?

After a storm and short power failure, I started having trouble with certain sites loading, and pages moving slower. I emptied my cache and defragged and ran total virus/ malware scan, but still had problem. (Pages loaded fine on AOL) I decided to uninstall Firefox and re-install to help fix problem. I did this, and now Firefox won't open, no matter if I double click, right click (open), or go through "all programs". I tried to uninstall and re-install again, but now I can't get it to respond through my control panel, either.

Try the procedures in the [[Firefox will not start]] article.

Firefox won't open on WIndows vista & it has worked for years.

Used task manager, closed firefox.exe & restarted, worked twice & I disabled Norton Toolbar. Now firefox won't open. I uninstalled firefox and redownloaded it & still won't open. Search for the Profile Manager doesn't show anything.
I did download an HP update yesterday. I am using windows explorer for this since I have toahve that on my computer to access some citrix programs

Right mouse click the iTunes icon and select "Run as Administrator"

Firefox won't open following update. Can't open Profile Mgr, even when using entire directory path in cmd line

I'm running Firefox on a Windows 7 machine. Firefox won't open following the latest update. I've read the help articles and it seems like I need to create a new profile because my settings have likely been corrupted. I'm unable to open Profile Mgr, even when using entire directory path in cmd line. I've tried the following commands in the command line:
firefox -p
"C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -p
Nothing happens with either command.
I'm also running Norton Internet Security. I read a help article Re Virtual Browsing features possibly causing a problem. The article said to check the virtualization setting in the internet security software and to clear the virtual cache. I went thru all of the settings menus in Norton Internet Security version 21.6.0.32 and I didn't see anything that looked like 'virtualization" settings, so I assumed that this doesn't apply to me.
If you have any ideas, I'd sure appreaciate your expertise!!

hello arcandl, when firefox isn't launching after you double-click on the shortcut this is sometimes also a sign of malware being active on a system.
you might want to try running a scan with some different other security tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] and [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner] which are specialised in removing adware and browser hijackers.

Firefox won't open because it says it is already open when it ain't

Firefox won't open because it says it is already open. It appears Firefox is operating in the background. Tried to remove it but we get the same message to log out of Firefox. For 10 years we have been using McAfee with all features but it does not detect any virus or malaware etc. It appears it might be a malaware problem but even using all the latest Microsoft fixes hasn't helped. We used Vista Business Professional with all the latest service packs updated. We use the latest version of Firefox as of up to around 3 weeks or so ago when this issue first appeared.

I suspect you need more expert help but here are a few things you can try.
If you can't open Firefox(double click on Firefox desktop icon) try Safe Mode - Hold down the Shift Key as you double click on the icon>don't check anything on the page that opens>continue. If Firefox opens and works in this safe mode go to Add-ons> Extensions and look for "Ask". Then look at Add-ons >Plug-ins and again look for "Ask" . Remove, delete,disable any Asks. If you do remove any, close Firefox. And try again in Normal Mode.
The Ask website has detailed instructions for removal but you need to find it on your computer and have your computer in working order.
If there is no sign of Ask and Firefox is working well in Safe Mode you should work your way through this -
https://support.mozilla.com/en-US/kb/Troubleshooting%20extensions%20and%20themes
Eventually you might need to grapple with About:Config and even your Windows Registry but I would recommend a complete uninstall and re-install before that. Unfortunately that often doesn't work.
That all sounds very daunting but taken step-by-step you might get lucky early.

Did you delete the profiles.ini file?
*http://kb.mozillazine.org/profiles.ini_file
You can use this button to go to the currently used Firefox profile folder:
*Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
*Windows: %AppData%\Mozilla\Firefox\<br>C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\
*Linux: ~/.mozilla/firefox/
*Mac: ~/Library/Application Support/Firefox/
You can use one of these to make Firefox create/use a new default profile:
*Delete the profiles.ini file to force Firefox to create a new default profile
*Use the Profile Manager to create a new profile
*Use "Choose Folder" when you create a new profile to select the location of a lost profile and recover this profile
