TOR..新手求助。

Torbutton blocked activity from a tab loaded in a different Tor state.

This is to work around Firefox Bugs 409737 and 417869.

If this popup seemed to happen for no reason, one of your tabs is attempting to reload itself in the background, and this was blocked.

To reload the tab in this Tor state, hit 'enter' in the URL location box.

这是什么意思啊？
