Needs an update.
I use Firefox with the Wacom tablet and then close the browser and the errors that are occurring are gone.
The purpose is excellent, it just needs improvements.

I'm a teacher, and this extension is great when you have something in the browser during lecture, and you want to draw attention to a paragraph or word or whatever. I leave the color set to red and just scribble a line. It's great that it remembers the color across invocations. Wishlist: I wish there were a keyboard accelerator to make it disappear, which would be handy during lecture when you're in kind of a hurry. Also in page-zoom mode, the ink appears slightly lower than it should, but it's totally usable.

old is gold

Best add-on for this that I've found so far. I like the fact that you can scroll and your drawings stay in the correct place.

It's a bit janky and has crashed a couple of times, but that's to be expected from such an old extension which hasn't been updated.

imposible usar con una tableta.

A extensão é ótima, uso bastante, mas acho que não faria mau nenhum colocar um tema escuro.

muito bom. Se em algum momento não aparecer mais basta usar ctrl+f5.

Плохо работает

It's very, very laggy (i.e. you draw and it takes a second to actually appear on the screen). I found a few bugs from just a few minutes of playing with it. Also, the pen drawing doesn't line up with where you click on the screen, it's slightly misaligned. As of writing this, the last update was 4 years ago.

If this extension were fixed I would have Firefox as my default browser. I use it all the time in Edge and Chrome.
