1. When I click on a link that opens up a new window, such as links in forum posts, I want Firefox to open a new tab automatically. I can use ctrl+click but that's a nuisance.
You know you can also use the middle mouse button to open a link in a tab, right?
Yeah, what he said, hehe.
I've been using Firefox since before it was called firefox. What did it used to be called guys, I can't remember? Thunderfox maybe? I still have the most updated IE, but I only use it for those very insanely rare occasions that sites require it :(
My favorite firefox feature is the middlemouse for tabs, second favorite feature is the plugins. Firefox is the way to go all around.
