thanks Rated 1 out of 5 stars

i'm using Fx14 on Win7 ultimate
it works now
i think it had a conflict with some other add on, as i had many of them with same functionality, i removed others and now its ok.
or may be the windows high contrast theme was the problem, Firefox has some prob when i use high contrast theme, even without this add-on i was not able to switch background colors and also many of Facebook thumbnails in albums were disabled (blackened)
thank anyway

This review is for a previous version of the add-on (0.13.1-signed.1-signed). 

Hi dharmendra.

I am using Firefox 14.0.1 on Linux and it works fine.

Please send me an email at and let me know exactly what you're running and what's not working, and I'll see if I can help.
