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.

Works great except the capture button gets in the way of pausing a podcast or changing the video speed with Video Speed Controller.

Has an annoying CTRL-SHIFT-V shortcut that gets in the way of posting content without formatting. I'd say this is a poorly planned shortcut key-combination. I could not find an option to disable or change this shortcut, so I had to uninstall the otherwise good add-on.

good plugin

best solution to annotate and refer the web

All I've really used is the highlighting - it's so helpful to be able to highlight parts of a long page so I can get back to them quickly.

It "was" a very good one. No other like this.
Now I wonder where the sticky note feature is.

Updated:

With next update which I manually installed because old Firefox wasn't updating plugins anymore, new setting appeared that allowed me to disable those video annotations. So now I can give it 4 stars. It still have toolbar removed and now to add bookmark I need to click too many times to go through all those steps you was able to skip previously, but it's not that big of a problem.

Previous:

Give you 5 stars? Hell no. I don't care about your annotations and you still showing me that Capture icon on youtube player, and there is no option to remove that damn button. And yes, I disabled everything else related to annotation in settings, but I still see that annoying button.

I have been using Diigo for a long time. This has been very useful. I don't have to re read the document again when I come back to it.

Only Complaint:
Please add a menu option to open the otherwise impossible (using mouse) "Annotation Toolbar"
For a long time my workaround was to do a dummy highlight, that would trigger the toolbar to show up and then I would delete the dummy highlight.

Now I know there is a keyboard shortcut for it "ctrl+alt+a" but for a new user or even an old user who has forgotten it, this becomes so much difficult. Now I have also learnt that in the options settings, one can set it to open the toolbar by default and I think this setting should be enabled by default.

Anyway adding this option to the toolbar should only help and not cause any issue.

Using it for all my Bookmark and Todo-Reads. Also works on my iPad.

I'm so glad the extension's been updated, but I really miss the bookmarks sidebar, and I wish the new annotation sidebar was integrated with the browser sidebars

Things like ESC to quit the diigo popup, ENTER to save directly.

Good extension, but comment logo on Youtube is annoying. Wish it could be set (fixed) to a different place.
