Which is better opera or firefox?

when you are cocmparing between opera and firefox then i would say that fire fox is much better than opera. firefox is very stable. it does not use a lot of system resources and also it has a very nice engine. but opera is not very system friendly. it uses a lot of ram. it does not have a lot of shortcuts like fire fox and that is one reason why it is difficult to browse on opera. also now in the latest version of firerfox u have the spell checker. and also it is much secure than any other browser so i guess fiore fox is always a wise choice.

I use Firefox from 2 years ago..i think is the best browser in the world,also for the many extensions with which we can improve our navigation.. Also Opera is a good browser(sure best than IE)but Firefox is the best for me!

I never used opera.I think firefox is better.

im using firefox for almost 6 months and feel comfortable with it ,but i have no experience with opera

I think opera win almost everything you asked, for me firefox is about speed, if not that fast enought I definatelly use opera as my main browser, when you add firefox with faster fox, it will fast enough to beat opera I think, and offcourse as compensation, it uses many resource of your computer, and this makes your computer work more harder, just imho.

A girl I met in college told me she used opera but at that time I had only just bought my computer and gone online. I remember though she told me she could open 100 windows at one time - which then I couldn't understand why you would want to but now I understand why she thought that was great. I hadn't thought about it untill reading this post but might give it a try, I use firefox with roboform for my passwords as my main browser, I use IE for InstantBuzz, I use crazy browser for traffic exchanges as it seems to be quicker but lets in more spyware than firefox. so I wiil give opera a try.
