Rated 5 out of 5 stars
Adverts have been removed in the latest update, so many thanks for that - I'd update my old review if I could, but figure a more recent, 5 star review will at least go some way to balancing things out.
Thank you Diigo!
"No adware or spamware!" - blatant lies Rated 1 out of 5 stars
It says on their homepage (http://www.diigo.com/tools/toolbar) that this has no adware or spyware, yet the latest version means every single time I go onto Google I get a very annoying, very obtrusive set of adverts, that are certainly caused by this extension (the element's ID has the word diigo in, and disabling the extension means the adverts go away)
I'd recommend you avoid this extension until they resolve this. Going to check out delicious as an alternative, because this is REALLY poor form imo.
