After some problems with the addon and its configuration, i've got some great support from Martin via e-mail. Now the plug in works with yourls 1.7.3 on my private server.

Broken and unsupported. Don't bother.

404 Not Found when trying to get an URL/signature

Does what it claims, simple and clean, THANKS!

The plugin is broken if e10s is enabled. But works fine as long as its disabled.

As another reviewer noted, 1.5 was broken. I was unable to get 1.6 to work, although an older versions served me well for a long time. I just made a new install of 1.7, and I can't get it going, either. I've sent an email to "Ozh," but I've not had a response.

The extension itself ist really great and worked like a charm.
Unfortunately the version 1.5 is broken and just gives me the error TypeError: gContextMenu is null in line 90. Back to 1.4 which still works.

Works perfectly , thanks!

I never imagined could exist, but I found it. Works fine in Firefox 12. Let's see if the developer is encouraged to do so for Chrome. Congratulations.
