    Is this the right place to ask?

    I'm loving FFQuantum 57.0b(64) however, after a successful week of having it be my default browser, I'm now getting "Couldn't load XPCOM." when I click on the FF icon in my Windows 10 Pro Task Bar.

    Got tip?
    Thanks, Kerry

    Hello Kerry and welcome to the forum.

    This has been a common problem for a while in Firefox (not just Quantum). The most common solution seems to be to download and reinstall Firefox Quantum. If it doesn't work uninstall the one you have first, go and delete the folder in Program Files, then try again.
