Command+Shift+L unexpectedly Googles selected text in non-Tor browser
I am using Tor Browser 7.0.5 on OS X 10.12.6 and I noticed a bug.
If I select some text, and then press Command+Shift+L, instead of switching to a new Tor circuit, like the keyboard shortcut usually does, it opens Safari and does a Google search for what I selected.
Sometimes, even if I don't have any text selected, Command+Shift+L opens Safari with text I have selected a few minutes ago. I don't know what exactly is triggering this bug but I'm able to reliably reproduce it by selecting text.
I think this is a serious bug because it can cause the user to accidentally reveal sensitive information to the clearnet (with their Google session cookies if they are logged into Google).
