Sliding the bar does not change the tab size at all. It does nothing, as far as I can tell.

Doesn't work for me at all (FF89) although it is written it was updated today. Sliding the cursor on the bar doesn't make any change. Any help?

This add-on is a simple way to change the tab size for any github file immediately. This only thing is, each time I go to a new page/file, I have to change the tab size for it to apply.
