Thank you very much for bringing back the use of Control + .
to flip tabs.
Thank you very much for listening.

I have installed it on Windows 7 64-bit computer. I use Control + . to try to flip tabs. It does not work in Firefox. Please enlighten. Thanks.

Unfortunately , older version of FLST does not work in Firefox 5 , Windows 7.
It was my favorite Firefox extension.
I really missed its keyboard shortcut . And the fact that closing current tab with Control + W focus on the right side of the closed tab, then I could use Control + .
to flip it back to last focused tab if I chose to.
One big less reason to use Firefox.
Or may be I should learn programming to update the old FLST.

Hi,
thanks for your review. Flipping tabs simply means that the previously selected tab will be selected when clicking the currently selected tab once more. There are no keyboard shortcuts. In other words: if you click your currently selected tab, and then click on it again, and over and over, you can switch back and forth between those two tabs (currently and previously selected one) by just clicking, without having to move the mouse. Please also refer to the (old) add-on called "FLST", which provided exactly the same mechanism.
Additionally, on closing the currently selected tab, the previously selected tab will be selected, too.
Best regards,
Fabian
