There are many linuxers who will kill me for talking about this browser or who will try to troll me a bit, I will tolerate it, nothing happens for it xD, but I can not shut up in front of the browser that for me is his majesty, both for my linux chakra, as for my windows 7 as for my symbian of the nokia x6 with the version opera mini.
When you are a user of where, you find yourself facing the same problem over and over again, all the complete, good and famous browsers are developed with an unappreciated interface gtk, we have no alternative to that, except to use browsers like recon, konqueror, qupzilla , which although they have good intentions, due to a bug in the library qwebkit, they usually crash the second time from the web with flash that you visit, something annoying is watching a video on YouTube and your browser disappears, really ...
Opera, has managed to adapt to each desktop, to each operating system in the best way, without discarding any and has managed to create a very interesting suite, with opera unite, opera mail, bitorrent client, opera turbo for slow connections and full support for 64 bits, a new html5 engine, ragnarok and notable qualities such as the finally arrival of full hardware acceleration and webgl since the version of opera next 12.
Although it may spend a little more resources than other browsers, in my humble opinion it is worth taking it into account, sometimes it is not so much the resources, but how the resources are used, I prefer a browser that uses more resources but is fluid , than one that uses less but gets stuck.
The Hispanic opera community is very active and sending bug reports is very easy, in fact it was really easy for me to report the error that it caused me when entering websites with flash about the effects of kwin, which went crazy and it was quickly fixed , or at least it was arranged for my ati.
The only defect, although for me it is not, is that it is proprietary.
