> There are no option to hide mozilla's top menu tabs (this why I wanted to use your addon as a replacement and do not see two tabs areas)

Please read the description of the add-on. This is a limitation of Firefox since some time. You can still hide the tab bar manually.

> and neither option to see mini thumbnailsin tab boxes itseve like I saw in your advertisment on that addon.

The thumbnails are displayed when the compact mode is disabled.
