I installed it, but I don't see any "browser button" I'm assuming the purpose isn't to merely create a bookmark for Google Scholar... support page does not exist or I would search for help. Using latest Firefox. I use Google Scholar almost every day.

Not open source. I don't trust it.

we need select from search bar, implement it other plugin.

The botton doesn't show up on firefox so I can't use it.

file is corrupt and won't load
