Solved: Mozilla Firefox: cannot open; cannot uninstall
My problems with Mozilla Firefox started about a week ago. Whenever I would click on the Firefox icon I would get two pop-up messages in succession informing me that I was having some kind of problem with "Chrome registration" and that I needed to "contact the author." At first this was just an annoyance since I was able to close these two pop-ups, after which a Firefox Add-On page would invariably and inexplicably open. After closing this Add-On page Firefox, finally, would then open immediately and function normally from that point on.

Tonight, however, it's finally gotten to the point that now whenever I click on the Firefox icon nothing at all happens. In other words, I'm no longer able to open Firefox. Also, I find it strange that I'm also unable to uninstall Firefox. Whenever I go into the Control Panel and click on "Uninstall a Program," and then click on the Firefox icon, I then get a pop-up tellling me that Windows needs my permission to continue. However, when I then click on Continue absolutely nothing happens; I cannot uninstall Firefox. (Actually, several days ago I was able to uninstall and reinstall Firefox, thinking that doing so would fix my problem, but it didn't. Now it won't even uninstall.)

Earlier tonight I did a System Restore, but that failed to solve my problem.

Since I use Firefox almost exclusively, I would really like to have it functioning again. I would greatly appreciate hearing from anyone who might have an answer to this perplexing problem. Thank you.

I've been online looking for solutions to my problem with Firefox. Unfortunately, anytime I attempt to do anything with Firefox I invariably get a Mozilla Crash Reporter box telling me that Firefox had a problem and crashed.

Also, recently whenever I tried running Belarc Advisor, for some reason I kept getting these same Mozilla Crash Reporter boxes. After several failed attempts I uninstalled and, using Internet Explorer, reinstalled Belarc Advisor. I clicked on the Belarc icon and the program opened and appeared to be running normally, that is until it got exactly halfway through "Checking the local network of this computer." At this point I got the message that it was "Not Responding."

I uninstalled Belarc once again. Next, I opened Google Chrome and again downloaded Belarc. I clicked the icon and once more it reached the midway point of "Checking the local network of this computer." This time, though, instead of Not Responding, it simply paused for quite a while before finally resuming and eventually running its course. However, instead of getting the usual Belarc report, once again I got the same Mozilla Crash Reporter box.

The more I try to fix things, the more confusing things get!

i think the uninstall in windows is not good enough. i suggest you download Your Uninstaller trial from http://www.ursoftware.com/ & try uninstalling firefox , also delete your profile directory of firefox.. ( if it still doesn't uninstall ,delete the program files of firefox & your profile folder), search your system partition for firefox related things-- use this software Everything from www.voidtools.com delete these too
if you have google chrome get rid of it too, after that run a good registry cleaner & run firefox setup again

"--after that run a good registry cleaner--".

Please do not do this; there isn't a "good registry cleaner."

See this info which I have in a file just for occasions like this:
Advice and Info re Registry 'cleaners'- excerpts from TSG:

The main reason they are apt to cause problems is because the cleaners do NOT just clean up stuff left over from uninstalls. They also "guess" that other items need to be deleted, many times incorrectly. They also attempt to "fix" references to files that no longer exist.

As a result, you can end up with programs that no longer work, functions that no longer work and in some cases a PC that will no longer boot.

There is no performance gains to be had by running these things. Windows does not read the entire registry when it is looking for something. It uses the keys which allow them to go straight to the item that they are looking for.

References:

http://www.computerhope.com/registry.htm


If you really want to see how active the registry is in your normal running environment, download and run Regmon.

http://technet.microsoft.com/en-ca/s.../bb896652.aspx

As you will see, the registry is constantly being accessed. If, for each of these, the entire file was being searched, your PC would be amazingly slow and not responsive.

And, to repeat this again, they make no difference in the machine's performance because they are based on a false premiss about how the registry is accessed. Unused entries do not slow it down.

I downloaded Your Installer 2008 but was unable to uninstall Mozilla Firefox. When I clicked to uninstall I got the following message:

Something is wrong with the unintalling process or you have cancelled your uninstalling process, some registry keys & files were not completely removed. would you like to remove them?
YES NO CANCEL


At this point I cancelled and closed the program

The problem must be with Firefox since I was able to use Your Uninstaller 2008 to remove two other programs. Do you have any idea why Firefox wasn't able to be uninstalled?

Somehow I was able to get Firefox up and running again. I have no idea what the problem was.

This time I clicked Firefox Setup 3.0.4 and ran it. Although it slowed down temporarily it finally straightened itself out and finished running its course. Then, all of a sudden, Firefox opened up. It resumed with the streaming audio from the site that was open when Firefox was shut down the other day. Could the problem have been caused by the manner in which Firefox was shut down?

The link below is to the official Mozilla site and gives info for uninstalling FF. You may want to save it for future reference. Glad to learn FF is again running for you. I am not knowledgeable enough to tell you why.

Thanks for the link, redoak. I've saved it for future reference, if needed.

I'm happy to report that things are completely back to normal with Firefox. While the cause of my problem remains a mystery, I'm glad that it's finally cleared up. Once again, thanks for your helpful suggestions.
