Do you think these add-ons are really necessary
Hello. Usually i use Firefox. I was religious about using two extensions, noscript and privacy suit. Recently i've been using Midori, and i like it quite a bit. Midori has the ability to block scripts but because it doesn't have exceptions, it makes some websites i visit like Facebook unusable, so that's a nogo at the moment.
Being religious about them two extensions on Firefox, and having almost no knowledge on securing a computer, i feel a little vunrable without them add-ons.
You guys that actually know what you're doing, do you think these extensions are necessary, and is it fine to not use them?
