I used both of them. I think FF is better

Definately Firefox if you are looking for secure web browing , plugins to add, extensions, and other things.
Opera is good but is not a choice for dialup users.

Firefox is better, more secure and faster than opera. thats why i used firefox.

[myhk2003]

[doubeprofit]

Firefox or Opera all of them are ok ? .but i like to use Firefox . access so fast.

I don't use OPERA

just FIREFOX or INTERNET EXPLORER

I prefer Opera, but FF is not bad. Opera is fast, secure, you can change position of toolbars on your screen, change position of opened tabs.

I NEVER USED Opera but used IE7 and Firefox .... and i foundfirefox good ,alot better than IE7 ... its browsing is alot better
One morething i like bout FF is the customization it offers in the form of Skins and Addons.

[MrJosha]

I like Firefox best, but unfortunately it lacks some interesting features I like with Opera, and even Internet Explorer.

I've been used FF for more than 5 years until now, with no problems, that's why I don't see any reason to change it
