a nice resource controller, although i feel the legacy version was simpler to use as others have stated.

okay
i tested it, this is what i want.
now i'm ready to leave my old ff version 55
but, i request a toolbar with on/off for every function , image, video, like the old prefbar
1 click is better than click+slide+click
thanks a lot

方便使用,不需要跳去另一个网页去设置。More suited for Android firefox for browsing without out of page setting

I truly like the fact that this extension allows one to set detailed policies instead of just allowing or blocking an entire site.

However I wish I could use wild-cards, such as '*' when white-listing web sites.

The reason for this desire is that it seems that after restarting Firefox and visiting Youtube, I am frequently unable to watch a video until I white-list xmlhttprequests for a hosts such as

https://r2---sn-n4v7knll.googlevideo.com
https://r2---sn-a5mlrn7d.googlevideo.com
https://r4---sn-5hne6nsd.googlevideo.com

I wish I could just I could white-list *.googlevideo.com once and for all. (The very large number of potential host names probably is a security measure.)
