Active Pinned Tabs

works as expect! love it. one flaw (-1 star) the pinned tabs will be closed if the window is closed. workaround (as per github source): instead of closing windows right click the further most right pinned tab and click "close tabs to the right". this way the pinned tabs will stay alive, move to a different firefox window when opened and the old "empty" window will close automatically

I've always been annoyed that pinned tabs don't show up in new windows (or that there is no option to make them appear). However, this extension doesn't do that either. Instead, the pinned tabs are moved (not copied) to the new window, so they are gone when you switch back to the window they were pinned in. So you still have them pinned only in one window at a time. Perhaps worst of all, unless you remember to "close tabs to the right" when you close the new the tabs are now pinned in, they disappear along with the window. Too bad about the many years of muscle memory… Also, there is an annoying delay when closing the window with the pinned tabs. In sum, at least for me the extension replaces a problem I was looking to solve with a bigger one. If you don't mind or even want the described behavior the extension works fine.
