Today I started having a problem with Firefox, my default browser on my Windows 7 Professional 64-bit computer. If I click on the FF icon on my desktop (or in the QuickLaunch bar), OR even if I click on a program that uses and opens Firefox (e.g., MultiG, which tells me whether I have new Gmail messages), I get the error messages below. First I get the "File does not exist" message. If I click OK, I then get the "Component returned failure code" message. And if I click OK on that one, Firefox opens! Apparently these are Javascript error messages. I don't know Javascript and I have no idea how to fix the problem. As far as I can tell, only Firefox is affected. I tried updating FF from version 18 to version 19.0.2, but that didn't make any difference. I suppose I could uninstall FF and try reinstalling it, but I think the problem started today when was uninstalling other programs. I no longer have confidence in my uninstaller programs, and I'd rather not try to uninstall FF if there's another way to fix the problem. Thanks in advance. Attachments:

Well, I think I solved my problem. I tried going into Firefox's Safe Mode to see whether the problem still occurred. It did not. That suggested that some extension or plug-in might be causing the problem. One by one, I disabled my plug-ins and extensions and tried to start Firefox. Bingo! I finally located the extension whose disabling caused the problem to disappear. I'm embarrassed that I didn't think of trying FF's Safe Mode before asking for help here. Oh well . I then thought of removing my request for help, but I decided instead to leave it up in case anyone else runs into similar problems.

glad you got it sorted, it happens to us all you know, not thinking of an obvious workaround immediately

Starting with Firefox 18 it got a new JavaScript engine. Since that happened I have come across various issues though many were fixed with version 19. However I have a few stubborn installs that I have kept with version 17 ESR until I have time to do what you did and track down the issue. So far every time I have seen this it has been an extension. I am glad to hear you found a solution. Leland

Wonder if Firefox is to blame on this one? Since the hackers found the vulnerability in Java, there has been a mad scramble by Java to patch the holes as they keep emerging. Could it be that Mozilla, and maybe the other browser publishers, are a bit behind on modifying their product to keep up?

Everyone uses JavaScript (an engine inside the browser) but not everyone needs Java (the plugin from Oracle). Leland
