Great !!! Rated 5 out of 5 stars
Wow !!!! ... sincerely ... I had lost any hope about recovering old-Autohide extension functionality.
Thank you very, very, very much for creating this addon.
I wonder if you could implement what in old-Autohide was called 'Zombie Mode'. This is a critical part on my Firefox usability experience ... and maybe some others too.
With 'Zombie Mode' I got my bottom taskbar at hand as if I were not using fullscreen. Actually I combined 'Zombie Mode' on one hand ... and ... on the other hand, using the window manager, I removed Firefox window top border. The final result was brilliant ... I had a real Firefox fullscreen with no-bouncing autohiding toolbar and tabbar at the top ... and a no-bouncing autohiding taskbar at the bottom.
As far as I remember I only used 'Zombie Mode' on linux ... because old-Autohide gave the option to show/autohide the bottom taskbar for Windows ... and nowadays I mainly use linux.
Thank you anyway.
It was sort of tricky, but this functionality will sort of be in the next version. It basically adds an option to apply the add-on while maximized, which should act pretty close to what your are looking for.
There might be a bug or two under Windows, but it works well under Fedora/XFCE with or without Hide Caption Titlebar Plus 2.6.0.
