For example, in Opera closing a tab returns you to the PARENT tab, in Mozilla (version I tried) you go to the next tab TO THE LEFT on the bar meaning you have to navigate and select the parent one (EVERY time).
Actually, this is incorrect, at least for the newer versions of Firefox. If you close a tab, you go to the tab immediately RIGHT of the one you closed. (in other words, in most cases, you will advance to the next tab you opened.) If there are no tabs on the right, you'll move one to the left. (which will usually be the parent tab.)
To me, this makes great browsing sense. For example... Say I'm looking for a small tidbit of info in large site map. I find two links I think may lead to what I want. I open each in a tab. I flip to the first tab... not what I wanted -- close it. Advances one tab right. I'm brought to the other link I had opened. Ooops, doesn't contain the info I want, either. Close it, and since no more tabs are open right of it, Firefox moves back one tab left, and I'm back at the parent page, after having run out of branches. It's pretty rare that I find myself battling tabs, or getting moved where I don't want to go. And, even if you do, a quick click or mouse gesture, and things are back in order. Oh, yeah, mouse gestures are cool. ;-)
I much prefer Mozilla over anything else I've used. (To be fair, it's been a few versions back since I last used Opera, but Firefox has been so perfect, I don't want to use anything else.)
A neat hint for disabling ALL Internet Explorer connections, and confusing lots of ad-ware enabled programs. Set your IE proxy settings to 127.0.0.1. This way, your computer tries to use itself as a proxy, and fails, thinking your internet connection is down. This eliminates the possibility of something using IE components (rather than IE, itself) to connect. (Most decent firewalls should catch this act, but I've seen it sneak through some. Certain versions of Zone Alarm, for one...)
