Hidden Gem! Rated 5 out of 5 stars

Once I found this extension I uninstalled Tagmarks. This does the trick with simple tagging, albeit with less flare than Tagmarks. Additionally, you get tools that make common tasks much easier and intuitive. For instance the one-click Copy URL button, or the Go Up button for doing just that. With my recent update from 1.1 to 1.3.5, I've noticed even more tools added. Unfortunately these are not as commonly used by me, and the extra buttons get in the way of the others. Which brings me to my only complaint, this extension needs an options dialog so this type of stuff can be configured. Thanks for this wonderful addition to my address bar, I look forward to further enhancements. This add-on needs more publicity, but right now I'm happy to recommend this to those I know and call it a hidden gem.

This review is for a previous version of the add-on (1.3.5). 

Hi 7KTech

Thanks you for this great review, one or two reviews like yours and i can nominate
this extension to the public area where more users can see and comment on it.

Regarding the options dialog, for now you can use the about:config page "Quick settings panel > about:config"
where you can configure this extension and more you can hide any icon you don't need.
