This addon changes functionality of other tabs. The problem is not exactly another user has explained below. It doesn't mess up with the context menu. If you open a new tab, a bookmark or even double click a web shortcut on your desktop while you are on a private tab, it open the new tab in private mode. If you right click a bookmark while you are on the private tab and click open-in-new-tab it opens the item in a new private tab, so it looks like the right click menu is not working. In other words while you are on a private tab it enter the private mode and opens EVERYTHING on private mode which is quite unnecessary and can be very annoying. The solution is going back to a non-private tab and opening the desired new non-private tab there.

This review is for a previous version of the add-on (0.1.7.5.1-signed).

This is due to changes in recent Firefox versions. :(

"Open in a New Tab" from bookmark context menu works fine for me and opens a non-private tab. May be some conflict with another extension or something else.
