good

Worked great until yesterday when it blocked Youtube and caused buffering all day...??? Whitelisted the site and it stopped immediately.

Edit - all sorted after the update mentioned below - thank you :)

对国内一些还是不够强大哈

Works without crashes on firefox 66.0 64bits windows beta version (instead of firefox 65.2 with crashes)

Today crash the FF when startitng, when disable its ok.
FireFox 65.0.2 64 bits

Firefox 65.0.2 crashes after the latest Ghostery update. Thanks for showing What's New tab. That was the quickest way to learn what's wrong. After disabling Ghostery in firefox safe mode, everything worked ok in normal mode. But the next second after enabling Ghostery addon I get Windows 7 APPCRASH of Firefox. https://i.imgur.com/deB3pzG.png
