I've upgraded to 6.0.1 and now firefox no longer loades AT ALL. I get this XULRunner error: Platform version "5.0" not compatable with minVersion = 6.0.1 and maxVersion = 6.0.1. What can I do to get Firefox working again as my browser?

After deleting everything, I've also tried to reload 3.6.12 fresh and I get a totally different nss3.dll entry point cannot be found error.

Download a fresh Firefox copy and save the file to the desktop.

  • When i try to open email (thunderbird) this is what I get: Error platform version is not compatible with minVersion =1.9.2.15 maxVersion =1.9.2.15 I understand this is a firefox issue. can you help? thanks, Jane

    i have also tried to uninstall firefox to no avail
    when i try to download 3.6.15 it works to 100% then is searching for viruses and there it stops.
    i can get on the internet with firefox... but can't get to my email using thunderbird... but i was told the problem is a firefox issue.
    yikes. i'm in over my head.

    I had already tried a reinstall before, but thanks for the suggestion. Starting FF in Safe mode did not help either.

  • Hi I am getting the following error message henc unable to start firfox at all: error message box as follows XULRunner Error: Platform version 1.9.2.4 is not compatibale with minVersion =1.9.2.6 maxVersion

    Error: Platform version 1.9.2.4 is not compatibale with minVersion >=1.9.2.6 maxVersion =1.9.2.6 maxVersion

    Eric, this can happen after a failed update that partially changed your Firefox install directory.
    Try a clean reinstall:
    1. Download the Firefox installer from [http://mozilla.com Mozilla.com] and save it to your desktop or other location.
    2. Make sure that Firefox is closed completely
    3. Delete the Firefox installation directory (On Windows, this is typically the C:\Program Files\Mozilla Firefox folder that contains "firefox.exe" and other Firefox program files and folders).
    4. Reinstall Firefox by running the installer you downloaded previously.
    Your personal settings, including bookmarks and history, will not be lost.

  • FireFox 3.6.15 will not start it is NOT compatable with Avast 6.0.1000 sandbox, it gives the following error when I try to open in sandbox: XULRunner Error: Platform version '1.9.2.15' is not compatible with minVersion =1.9.2.14 maxVersion = 1.9.2.14

    Before FireFox was updated to ver 3.6.15, FF would open in Avast sandbox with no issue. Since the update to FF I can only open FF outside of Avast sandbox. Avast version 6.0.1000
    I turned off all Add-ons and still No Joy!

  • HT1222 I just installed this update and now I cannot access "Mail" at all.  I tried reinstalling the program, but that does not work, either.  Help!!!!!!

    I just installed this update and now I cannot access "Mail" at all.  I tried reinstalling the program, but that does not work, either.  Help!

    Paldeng, thanks for the suggestion.  I've done all that.  I can connect to the server, but apparently they are not recognizing my ID and password.  I can use the server program if I don't go through Mail (using the same ID and password).  My mother in another state with another provider has had the same email issue, as also my husband on his laptop who uses the same internet connection I do.  His worked fine until we had it repaired at the Apple store and all the original programs reloaded (with the required updates, I assume).  We can receive email in Mail, we just cannot send.
    I contacted my service provider, and we went over my connections.  They said it was not their problem and connected me with Apple, resulting in a charge to me because my warranty is long expired.  Apple swears it is not their problem, it is the provider, so here I sit.  My son was able to fix my Mom's Mail (she's 97) and got my husband's working also, until mine went out, by tweaking connection descriptions and ports remotely.  The thing is, we had not messed with any of those settings, so what changed?  I just did not want to bother my son again, as he has many other demands on his time.
    Since this fiasco with the Mail v4.6 update, I'm wondering if something else was updated that works well with Lion and Mountain Lion, but does not work well with Snow Leopard and Leopard.  I think the problem I had with the Mail update was that my Mail program had been renamed to Mail (original), and therefore was not being recognized by the update.  Perhaps they had another tweak in there somewhere that is affecting outgoing mail connections?
