Good Morning! My First Post here!!
I used to be NoScript/ABP user long time ago. And switched to uBlock Origin (Medium Blocking Mode + popup/remotefonts disabled), and Firefox configured (to block 3P cookies + click to play plugin content).
I switched for one single reason, is that i can do script/frame blocking + Content Filtering with one extension. However, i have one lingering question in mind, which i am not completely satisfied with the answers over the web. Henceforth, i am asking your input/advice on what i would loss interms of security by not having NSS. Anything i can configure natively in Firefox itself.
There is one i know, which is if i have site whitelisted in uBO, and if that site is compromised by XSS, i might be vulnerable there. Anything else?
Thanks in Advance. I am looking your input from technical standpoint, meaning i would be happy/satisfied if you people can give real uses cases

Thanks, Harsha.
