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

Great productivity extension. Using them for years, excellent replacement of Delicious. I hope the business model survives, it'll be hard to find a replacement for these ones!

I love Diigo!

Diigo is great

I LOVE Diigo. Highlight, Annotate, Collaborate... it's great! :-D

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.

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.

Been using Diigo forever. Glad it works beautifully on this hugely modified version of Firefox. Good to see that lower case d icon on the menu bar.

For me, this a must-have extension in every firefox installation I made for a awesome service!

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.

Really great for research!

Fantastic app well worth paying for. The extension works flawlessly and greatly enhances my experience on the internet.

As a side note: It would be very convenient to have a quicker way to turn off seamless annotation pop-up -- going to settings is a bit cumbersome to turn it off for the few websites where it is not necessary at all. (or, maybe there could be a blacklist of websites where it is always disabled?)

Nice developed addon, like the visual. Keep the good work ;)

It's very convienent to mark a website

I've been using this extension for years. But I had to disable it because is breaking something within the browser for visual formating to XML files.

When diigo extension is disabled, everything works fine. I work a lot with XML files. So if I have to choose (as I did) I go with natively formated XML.

Hope you can fix this.

Excellent for annotating the web and even just for bookmarking.
I much prefer this to "pocket" thanks to it's "tag sifting" functionality and now the Firefox add-on is as nice as the Chrome one... it's perfect!

Could you please clarify why do you need to access googleapi data , account.google data and clipboard data?
As specified by an other comment i'm worried about my privacy and I could'nt find any decent technical explications about why do you need those new permissions..
I saw that you're now able to read pdf files from Google Drive so I understanf it's linked but what do you have access exactly? Is it possible to deactivate this option?
I'm not upgrading until I do not have clear and sound answers.
