I recently began using the latest Opera for 64 bit on my Opensuse 64 bit 11.3 laptop.
I like it quite very much, and it comes with an email client. Anyone else using Opera?
Sometimes
It’s a nice browser, but it’s been a little buggy in Linux of late. It has nice features and it pretty quick too.
I’ve been using it since version 5. I prefer it to Firefox.
I prefer open source software, especially for security critical applications such as web browsers.
I prefer Firefox; I like the add-ons especially the adblock and noscript.
I prefer SeaMonkey and/or Firefox for reasons already posted.
Until recently, that would have pretty much described my position, but I have found the last couple of releases to have minor, irritating, flaws and I’m considering switching to Chromium.
I used to be an Opera user, but then I switched to KDE, and since KDE has its own great mail client, feed reader & downloader I dropped Opera because I hate function duplicating. And, Opera had some problems with Flash and IMAP mailboxes. But I still think it’s a great software.
Opera? Yes. from version 3 or 4 on, when I paid 36 dutch guilders to get rid of the banner. I don’t really have a preferred browser, but Opera’s mailclient is my favorite mailclient by far. All my mail life is in there, from 1998 up to now. Over 40.000 messages, still fast, anything found in secs.
I have been using Opera as my mail client and browser for a couple of years now.
One of the biggest reason why I prefer Opera to Firefox is: Firefox does not provide any method of customizing keyboard shortcuts. Keyboard shortcuts
I have been using SeaMonkey as my browser and mail client.
I recently deleted Opera when openSUSE was going to force more new software on me for an Opera update.
It depends on my usage. If I’m doing research then Firefox. Otherwise, I prefer Opera.
Although at this stage my browsing is spread out over a number of browsers: Rekonq, Epiphany, Opera, Chromium, and Firefox.
Back in the Opera 10 days, it was the best browser that could claim (semi)native construction under KDE, since it was built with Qt4.
All the best browsers then were GTK-bound in some way.
I’m now using Opera 11 Alpha with Adblock and notscript and I have switched browsers from Firefox to Opera and it works Great; other than the time it takes to load…but I will live with that 
Cheers!

Thanks for the tip. But I still think it is too much clutter, and I prefer Opera’s sort of “batteries included” approach where the basic installation pretty much has all the functionality I need, whereas I have to install several extensions in FireFox in order to make it usable for me.

True, the basic Firefox is actually pretty frugal. I myself have about 35 addons installed. 
I’ve actually been using Chromium but recently tried Opera. It seems nice enough, though my only real annoyance with Firefox is the speed. If Mozilla fixes that up (cold-start speed, etc.) then I would love to be able to jump right back into it!
I prefer Firefox.
Neither, I would choose Chrome.
Firefox is a good browser anyway, but Opera (from what I’ve heard) is sleeker.
I use firefox. But when I gave opera a try I liked it. I will consider using it again.
