I use this ass-on to animate a school mag with students (10 to 15) and find it very usefull

It's useful for schoolwork. And for annotating articles.

i am a paying client since 4 or 5 years, the Firefox version of the highlighter works in 80% of the pages in chrome works perfect. Updates come every 2 years or something like that? ...painful. I continue paying because there is no decent alternative, it's a pity

Cannot sign in, cannot find support to get extension working. Stuck in an endless loop of asking me to sign in.

I like Diigo. Works well. Use it for annotating websites to find back relevant information.

This extension was always clunky but since few weeks, it does not work at all. I highlight pages, they appear highlighted and when I revisit them, they are gone.
Few dozens notes went to waste before I realized all my work is not being saved.
I had "Professional" user tier mostly for assets fetching but this too stopped working.
Diigo prides itself in staying online for 10 years now: being online is one, keeping your product working in ever-changing Web is another.

Excellent add-on and service.

This is the best thing after del.icious gone wrong. A very good bookmark organizer. I wish they had a backup feature where you could export all the bookmarks in html. I miss it a lot.

Firefox is the go to...(on account of)...??? Not processing data...Accept...(you forgot to use firefox)
