Excellent, but conflicts with SingleFile, making it impossible to save files.

Love this add-on, especially the ability to customize the color. If there was a way to remove highlights it'd have five stars!

Effective Add-on, but need some attention:
1) You can't save the highlights if you refresh the page. Be careful and print your screen.
2) You can't "unhighlight" your annotations.
So basically It's a highlight in a paper from real life lol.

It highlights. But it doesn't unhighlight. Would be great if development continued.

This is what I want, simple and it works well.

but, It will better if I can open setting page in addon manager like other addons.
