No longer works in latest version of Firefox: doesn't load my tags or my outliners. This is now useless to me as my main browser is Firefox.

Well - it works, but beware that when you're on the Free plan, you have a limit of 500 annotations, and it's not mentioned on their webpage or during the sign-up process, which is shady.

Keep in mind that you can still make annotations after you hit your limit, but making a new one will force you to dismiss a popup box that tells you that you're over quota, and will nag you every time you visit their webpage.

The premium subscription is priced ridiculously, at 40$ a year. It certainly DOES NOT cost them 40$ a year to host small text files and a few megabytes of cached content. Developers should be paid for their work, but what they're charging is far too much for such a basic service. In contrast, you could get 100GB of Google Drive storage for 25$/year, and Apollo Ultra costs 10$/year, and that developer actually communicates, updates the app and is transparent about their billing practices.

Not only that, but updates are extremely rare (just take a look at their blog page, the last post is from May 2018), and their "Groups" social feature looks like it hasn't been updated since 2008. It's also filled with spam.

All I want is an extension that allows me to annotate without connecting to any cloud-based service (Seeing how they barely update anything, security is a concern).

Alternatives to Diigo are relatively hard to find. I would have thought that extensions that let you highlight, annotate and tag would have been more commonplace, but the only actual alternative I found was hypothes.is. That service is updated much more frequently, and costs nothing for non-LMS uses. The main drawback to that, however, is the rather clunky UI that doesn't play well with NoScript and the lack of an official Firefox extension, as well as the constant cloud connectivity.

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

Diigo service is excellent, but modern versions of the Diigo extension are troublesome.

Prefer legacy Diigo Toolbar 5.1.0.38, with Waterfox instead of Firefox.

Current version 6.0.0.4 seems unable to bookmark PDF URLs, and so on.

I am continually told that Diigo Web Collector is slowing down my Firefox browser. Is there a solution for this as I like using both products.

The capture feature interferes with my audio transcription work with the annotate feature sitting right on top of the audio slide, which makes it sometimes impossible for me to re-listen to portions of the audio. There doesn't seem to be any way to turn it. Although I like the webpage archiving, I am seriously considering finding another way to save webpages.

This update has made Diigo all but useless to me. The only reason I'm keeping it is because the "email link" function, while slower now than it was before the update, is still faster than any other I can find. As soon as I find a faster one I'm out of here.

YES, the missing toolbar does suck! But I can get over that. PLEASE, JUST ADD THE STICKY NOTES TO THE NEW DIIGO BUTTON!

The sticky notes are an extremely useful tool that I use often to cache arbitrary data on a webpage. I'd say it deserves to be in the main menu, more than the "Annotate PDF" or screenshots or whatever...

Thanks though, great tool

Where is the one click bookmark - where are the drop down tagged bookmarks on the toolbar? An annoyance

I need it. Also wasted a lot of time diagnosing where it went and why I could not get it back.

Nothing more to add to all the other voices who request it. Why did you retire the most useful features? Please bring them back asap.

I've used this tool for years and I pay to use it. Why would you take away wonderful paid features? Please bring them back. I use these features daily!!!

This may have been one of the add-ons that kept me using Firefox before this last update. Integration into the toolbar allowing me to access my bookmarks without requiring me always go through the Diigo website was one of the main features that kept me using Diigo and Firefox. It was built into my daily routines. Without it, I now have to look into other alternatives. I have not fully reviewed the entire latest update so I will continue to review it, but as of now I am looking for better options.

What happened to the Bookmarks Sidebar? I don't want to have to go to a website to get to all of my bookmarks. :-(
