It's not working since months. Chrome extension does working.

It has been a long time that this addon has stopped working. In general the whole Diigo service has been going violently downward. I was just re-billed for the annual 40$. I don't see myself paying again.

I was good until it stopped working... switched to Raindrop.io

No longer works. Going to switch to a different bookmarking service.

Not working any more. It used to be good. Requires too many privileges.

The latest version doesn't work in Firefox/Linux. Previous version works.

Bookmark saving does not work in the latest version.

You can get the previous one (6.0.0.4) in the section "version history - See all versions"

It may not work directly so right click on the "Download file" link to save it locally.

It will throw an error when trying to install the extension file by double clicking the extension file. In that case:

* enter about:debugging#/runtime/ at the location bar.
* Activate the "Load Temporary Add-on" option
* try again to install from the local file.

Folks reporting this is now broken would be more correct in saying that how it works has changed. Use the "annotate article" from the plug-in drop down to get refreshed view of the page you want to annotate (w/o the site style sheet). Admittedly not as groovy as before but all my content and ability to make more is there. It's a great tool and concept!

Sadly, this does not work anymore.

no longer works in Firefox/ Windows... such a shame! This was such a powerful research aid.

stopped working recently, I've got not feedback from support on my report

Stopped working since a couple of weeks. Doesn't seem to be actively maintained anymore. Time to migrate to Raindrop.io or TagPacker.

Worked well for a long time, but now broken on Firefox

The extension has stopped working on Firefox. I have been a major Diigo user for years and have a premium plan, but if the extension does not work on my preferred browser, I might have to look into changing what tool is use for web annotation.

The addon does not work any more.
it works on android app but not on firefox
Please could you fix it? thanks !

Diigo does not answer priority support for premium customers - Diigo appears not to work any longer in Firefox. I have used diigo for many years.

I use it a lot, but it does not work since latest update (v6.0.0.5resigned1), please, fix it!

I was a very satisfied (premium) user of this add-on for over 15 years.

However, in the last year, the experience has deteriorated: saving images does not always work, and searching for annotations from the web interface often returns no results, even though the searched text is present in an annotation.

With the latest release (6.0.0.5resigned1), the add-on has stopped working entirely. I contacted care@diigo.com to no avail. I, too, had to revert to the previous version.
