After clearing all cookies, site data and cache in Firefox 62.03 Win 7 x64, I closed the browser and launched it again. I signed into Google successfully. Next to my profile top right, I clicked on the Google Apps icon (nine dots) and selected Youtube. I get an error saying: "There was an issue signing you into Youtube. Troubleshoot here." I repeated this whole procedure several times but I am still unable to get signed into Youtube on Firefox. I do NOT have this problem in Chrome. Please help.

The screenshot refuses to upload. The little circle just keeps on turning. One tab shows where I'm signed into Google and on the next tab it shows the Youtube page with the error stated above.

Being logged onto one site should have nothing to do with being logged into other sites. I am logged into those sites and several others as well.


Many site issues can be caused by corrupt cookies or cache.

  • Clear the Cache and
  • Remove Cookies

Warning ! ! This will log you out of sites you're logged in to. You may also lose any settings for that website.

If there is still a problem, Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Did this help?

While you are in safe mode;

Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.
