I have tried all of the major browsers and even some minor ones, too.
But Opera is the best browser that I have ever used. Everything or many things are built into it; RSS feeder, email client, extensions, synching, pop-up blocker, a very good download managertorrent manager, etc.
Since the new versions (11 & 12), it has downgraded because of the removal of the Unite feature which was great, it is too bad it is gone. Also the widgets are removed. But the addition of extensions has proved to be a good one. It is light and fast, maybe the fastest browser when including old OS and hardware architecture. It is easy to use and customize. It is probably the safest browser to use and is toolbar proof because it does not allow toolbars to be attached.
The only negative thing I could say about it is that it does not render or translate all websites. Some people may find that some websites are rendered wrong or jumbled.
I highly recommend it.
If you have a slow connection (56k to 256k), especially Dial-up, Opera is the ONLY CHOICE. Picture 500x375 pixels on Firefox is 51.1k. The same picture viewed on Opera with Turbo enabled, is 11k and downloads in about 14 to 15 the time. Clicking between Firefox and Opera browsers there is no difference in the quality of the pictures downloaded. ....How is this possible?
Not a big issue now that most people are on high speed broadband (unlimited), but if you are on a slower connection, Opera is the only way to go.
Just like a home brewed coffee I always have beside me while strolling 'round the net, Opera always bring a nostalgic phenomena that I seem to never get from other browsers at par with it. I stayed long with GC and MFF for the longest time I can remember, even had fun tweaking them to best fit my flavor and played around with their huge db of extensions but whenever I get updates for O, it never failed convincing me to get back (as opera seldom releases stable build so I stayed to giants for quite some time).
Despite of it being low on market share, I'm actually impressed by how the company stay put all throughout, staying cool while all the others rushing to get things done. Proud to say it pioneered a lot of innovations, and compiled it to a very tiny size; always aim minimalistic at its bet, not compromising the overall performance; utilizes power and memory efficiently giving us a fluid browsing experience and best of all, (at least for me :D ) the way its smooth scrolling ease in throughout the pages that NEVER tires my eyes. (Those who uses Opera knows what smooth scrolling is, I bet).
I mean, not being biased here but I think this is one of the most important things a feature-packed web browser should put a great effort to as this has a huge impact on over-all browsing experience, imho. Thumbs down to web developers who are lazy enough to implement web standards and exclude opera.
