    I've already purchased AVG and don't want to pay twice to have it downloaded.
    Please.
    It's on my file under my email.
    Thanks

      @Kristina: Use another browser (e.g. Chrome or Internet Explorer) to access your email and to get the "Activation Code" for the AVG.

    Instead of trying to "REPAIR" Firefox, CAN I DOWNLOAD CHROME…WITHOUT first removing / doing anything with FIREFOX?

    Method 1 of reinstalling worked fine for me.

    Methods 1-4 didn't work for me, but after step 4 I discovered that the program started OK when double-clicking the icon on the screen (without resorting to safe mode) but NOT by clicking once on the icon on quick-start bar – strange. I deleted the icon on the quick-start bar, restarted FF from the icon on the main window – allowing the icon on the quick-start bar to reestablish itself, and everything is now back to normal.

    With the new version of Firefox (68.0) upgrading doesn't work because it won't share data with older versions due to tighter security protocols. So what do you do, I had lots of extensions and xpcom also prevented Firefox from loading in safe mode?

    What did was to save the relevant C:\Users\%username%\AppData\Roaming\Mozilla\Firefox\Profiles\ folder as backup (I didn't need it). Uninstall any versions of Firefox you have on your pc using the standard Microsoft uninstaller. Download the previous version (67.0.4) and install it. I unchecked the mozilla maintenace option to limit its capacity to upgrade in the background. It picked up the data from corrupted installation and everything is now back and working.
    If it doesn't work try downloading at the installing the 32 or 64 bit version instead.

    I paid for another year of Vipre; but, due to a non-standard distribution of software and data on my three internal drives, I ended up without a working copy of Vipre. I downloaded the free version of Malwarebytes, which found 178 PUPs or worse. By the time, I had solved my virus problem, Firefox was no longer in evidence. I do not recall uninstalling it. In any case, with no further changes, the XPCOM problem was solved. I will reinstall Firefox (67.0.4) when time permits. Thanks to all.

    After updating the portable version of Firefox, this message began to go out. In safe mode it does not start. Firefox disappointed unpleasantly. In the pit!
