Tor Browser page tabs crash on initial loading of sites including Tor

"Gah. Your tab just crashed.

Choose Restore This Tab to reload page content. "

Tor browser worked for two days and then began to crash immediately upon loading a clearnet web page. I could not get any of the Tor web site pages to load or the reddit site but I was able to get DDW and DDG clearnet pages to load.

This same issue initially occurred 6 days ago so I uninstalled Tor and reinstalled it. And as you can read from above, same behavior. I am running windows 10 pro, ipVanish, and Tor's bundle NoScript, HTTPS everywhere.

Just now I launched Tor browser again and was able to read Tor web site. i went to reddit and read several pages. Clicked on a link in the reddit thread to another reddit topic and Tor browser crashed.

I don't know what to do to get a usable version of Tor browser. I am using 7.0.6.

Thanks.
