FF 107: It just does not work. At all.
I can add it, see it in toolbar but all functions are disabled. I can imagine a vault must be assigned for the plugin to work but there's no way to do so.
In this state the plugin is just cluttering the extensions repository. Please remove.

Doesn't work. "Vault not found"

open obsidian then errors. "can not contain (special characters). and no way to indicate what path file exactly? or is in the clipboard of obsidian? why people doing plugins don't give more help. I imagine you didn't this in 5 minutes...but it is not usable

Doesn't even appear as an icon in FF, so I can't even use it at all. No idea how I am supposed to clip a page.

The app didn't appear to work.

Unusable. The clipped page is truncated halfway.

As of 12/01/2021, the add-on only creates blank pages. The GitHub repo hasn't been touched in ten months so I imagine the project is dead.
