Works fine! Avaliado em 5 de 5 estrelas
Although there weren't any updates recently, the add-on still works absolutely fine (tested with Firefox 51), so I have no idea what problems FirstLast describes.
I also like the simplicity of the settings, thanks!
The add-on even works when the multi-process (e10s) feature is enabled, however it is not yet marked as compatible (which hopefully changes soon: https://bitbucket.org/veg/advlocbar/pull-requests/1).
It's updated, a new version is under review.
