[Firefox 9.0.1] The URL is not valid and does not..

Solved

Hello everyone!
-
I'm reaching out because Mozilla is acting up.
-
After installing the software, the default homepage of the browser (about:home) won't load, and a message appears: "The URL is not valid and cannot be loaded."
-
The same goes for "about:sessionrestore," which allows you to restore your tabs after closing the browser.
-
I see you might suggest plugins/add-ons that could cause this issue, but in my case, that's not it! I've just reformatted the PC and NO add-on has been installed on FF yet.
-
I tried a clean reinstall with ccleaner, registry cleanup, etc... nothing. I attempted to install an older version and then upgraded to the new one from the browser... still nothing. I even tried to reconfigure the homepage internally (about:config) in case it was a configuration error during installation, and guess what? Still nothing!
-
I thought it might be a bug in FF 9.0.1, but no, since FF works perfectly fine on my friends' computers...
-
So after (almost) trying everything, I'm turning to you, professionals, geeks, hobbyists who might have a solution to my problem!
-
If you find it, you'll make more than one person happy because apparently, this issue also affects quite a few people online (http://www.commentcamarche.net/forum/affich-2825968-firefox-alerte-l-url-n-est-pas-valide for example)
-
Here are my specs:
Windows XP / Firefox 9.0.1

    Apparently, this is a known bug in XP SP3 that makes the entry list of about:about incomplete and also causes issues with missing protocols, hence the URL error that breaks the M&M's.

    One way to fix it: install Net Framework 3.5!

    For everyone who has the same issue, we FINALLY have the solution!

    Thanks to who? Abraxas from Geckozone! He's awesome :)

    Good evening,

    I suggest you uninstall Firefox and perform a clean reinstallation.

    Before uninstalling it, you can back up your bookmarks:
    Open Firefox
    Bookmarks
    Show All Bookmarks
    Import and Backup
    Export to HTML...
    Save it on the desktop.

    Go to add and remove programs and uninstall --> Firefox

    During the uninstallation of Firefox, agree to uninstall everything,
    check: delete all my files

    After uninstallation, restart the PC, go to: C\program files and delete the folder --> Mozilla Firefox.

    Run -->CCleaner for a cleanup in Windows, applications and registry.

    Then the suggested procedure is to delete the keys in the registry.
    Go to start
    Run
    Type: regedit and OK.

    At the top, click on edit, find (Ctrl+F), type: mozilla, check the keys, values, data boxes and click next.

    The search begins, when a file appears, delete everything related to mozilla, then press F3 to continue the search and do the same until the search is complete.

    Repeat the same procedure by typing: firefox

    Install --> Firefox
    Then to recover your bookmarks:
    Open Firefox
    Bookmarks
    Show All Bookmarks
    Import and Backup
    Import from HTML....
    Next
    Look in: desktop
    Select -->bookmarkbackups.html

    Check if the cause could be --> ask toolbar or others?

    Run this utility --> AdwCleaner
    and click on search.

    Look at the report and if there's the presence of toolbars, adware, etc... Restart it and click on delete.

    Download and install --> MalwareBytes

    Update it and run it for a scan.

    Check this --> tutorial

    Don't worry: it's a known bug in Firefox 9.0.1. It happens to me on XP SP2 and XP SP3, but there's no problem on 7 SP1. We just have to wait and hope it gets fixed...

      That's the most plausible answer! But when will this bug be fixed?...
      Do you have a link to contact the Firefox staff?

      Thank you for your response!

    Despite a clean uninstall and reinstall of Firefox, it is quite possible that there is an infection?

    So it is up to you to execute the proposal in the --> message 5
    or to open a new topic in the forum --> virus/security
    and request a system analysis to check for an infection.

      There is no infection. It's either a bug or an error in the executive script somewhere in the system.

    So Windows wasn't up to date?
