Rated 1 out of 5 stars

I reviewed this addon sometime ago with five stars. Starting with Firefox 27.x, the addon began to work inconsistently. Sometimes it would work while other times it refused to work.
When it worked, most of its features stopped responding at times freezing Firefox.
With Firefox version 28, the addon not only is not compatible now with Firefox, it will now interfere with the proper functioning of the browser.
In a lot of cases it will prevent Firefox from even starting.
Additionally, this addon has not been updated for a long time.
Developer could perhaps answer if he still works on this.
