I originally gave 4 stars, but lowered it to 1 - because this work is just a clone of "Bookmark Tabs to the Right" extension (https://addons.mozilla.org/en-US/firefox/addon/bookmark-tabs-to-the-right/), just changing the name. I have to admit that the original extension name is confusing, but just changing the name and add as a new extension is not ethical.

At least improve it or add more features then introduce it as an improved version, giving the proper credit to the original extension author.

Firefox 77 - This feature is available by default.

Tab>right click>select all tabs>bookmark all tabs.

Please remove this extension. Its confusing.

Added add-on but I see no option to use it.
If it is not compatible with Firefox beta on Android, why let me install it!
Removing.
