Opera or Firefox with security addons???

Hello,

I´m currently using Opera, SandBoxie, Comodo Internet Security (Defense+ and Firewall) and Avira personal. I´m also cautious when browsing.

I was wondering if Firefox with some specific addons will provide me be a little bit more safety than Opera...

If yes, what would be the best security and privacy addons for Firefox?

Thanks!

 

Here's mine. Some are greyed out as i've disabled them for now. But all except KL and SP would help go a long way with privacy and security etc. Please ensure you set ALL the options etc as you wish, and correctly, otherwise you won't benefit totally from what's on offer.

By the way, you have a fine set of Apps there.

 

I've very recently switched from Opera to Firefox. I use some of the add-ons listed by StevieO. Here are the security add-ons that I use that aren't on StevieO's list: LastPass, LinkExtend, and Perspectives.

 

I looked at BetterPrivacy, but decided to simply include the locations in CCleaner.
