The plugin works great, it's reliable enough for me to not worry about missing new content on an important page.
However, I'll humbly take 3 stars off for jumpscaring me every time an error occurs. The sound is as obnoxious as it gets, and for some reason it's MUCH LOUDER than the rest of the sounds on my system, even including music. I'd love to see an option to change/disable that, until then: 2 stars.

Actually, ignoring the reviews + regularly checked pages popping up on the "pop-up" window when doing sth else in them = 1 star, why not.
