Okay, I will settle this once and for all and say that both Firefox
and Opera suck! Internet Explorer is by far the best browser.
Now, thanks for writing the article, Brandon.

A lot of this can also be applied to other browsers. I would be too lazy to enable JavaScript only for sites that need it though. When Opera supports CSS3 attribute substring selectors, users will be able to make more powerful CSS to block advertisements or anything like that. If Opera doesn’t download objects with
display:none; applied (I believe it doesn’t.), that could speed things up.
Opera users, as well as everyone else, can block certain domain names with the HOSTS file or whatever your operating system provides. There are lists out there. When I had a really big list, my computer was sometimes unresponsive, so…
Oh, notes have been seen in other browsers. You are right about M2 not being in other software, but I shouldn’t think Opera would allow that.
