Works even in Firefox on Android. Actively developed. Thanks.

cool
+ add title + comment...
+ tag search autocomplete (wow)
+ search in shaarlies
all in one, clean interface :)
Missing : an option to open in a popup !?

I self-host Shaarli with YUNOhost and had the problem of having to re-login because the session cookie expires too soon. This add-on works with the REST-API, so no more of that - excellent!

Note that you can set keyboard shortcuts to the addon in 'Manage Extension Shortcuts'.

The integrated search function is nice but works only when the plugin is active. The search function searches the complete metadata (not only the tags), just like the web UI.

At last a Shaarli extension which is still actively developed. My privacy settings in Firefox renders the Shaarli bookmarklet dysfunctional, so I am very happy that Shaanti provides the the possibility to post bookmarks to my Shaarli instance.
