I'm giving this an above average rating because I think it has great potential and I want to draw attention to it. Please encourage the author to work on it more.

It LOOKS awesome, and seems to be exactly what I have been looking for for MONTHS.

So far, however, I have not been able to get it to modify anything. I.E. it can't write any changes you make.

I can't help but notice that in the store at

https://addons.mozilla.org/en-US/firefox/addon/extensions-manager/

it states that it needs two permissions:

"Monitor extension usage and manage themes"

and

"Store unlimited amount of client-side data"

YET IN THE CONFIGURATION FOR THE EXTENSION, IT ONLY LISTS ONE OF THEM:

"Monitor extension usage and manage themes"

SO, obviously, the browser isn't giving it the "Store unlimited amount of client-side data" permission or doesn't know that it requires it...so it can't save anything.

AUTHOR, CARE TO FIX THIS PLEASE? Thank you for writing this, I'm sure it will work great soon!
