  • I can't sign into my Microsoft account using Opera. I also have that problem with Firefox. I have to use Vivaldi, Edge or Brave to sign into any of my Microsoft accounts.
    This problem started about a week or so ago. Help would be appreciated because I like Opera but if it doesn't work and it can't be fixed I'll have to uninstall it.
    I disabled my virus checker, and anything else that might cause a problem.
    Help would be appreciated
    Thank you...

  • @johnl600 No problems logging in to my Microsoft account here.

    Already tried cleaning cookies and cache? What about turning off extensions?

  • @leocg
    Thank you.
    Yes I also turned off all extensions.
    I uninstalled Opera and DL and installed a fresh copy with no luck.

  • @johnl600 Did you remove your data when you uninstalled Opera?

  • @leocg
    I didn't get a choice when I uninstalled it but I did a search and deleted everything that had "opera" in it.

    What I finally figured out was I have a program called "System Mechanic" that was blocking both Opera and Firefox from signing into Microsoft. I uninstalled it and now I can use both browsers again.

    Thank you for your help.
