People tend to assume that if Firefox 57 or other version will be faster then Chrome, then a lot people would then start to use Firefox instead of Chrome.

As much as I would like to see that its not gonna happen, and I am writing this as a Firefox user.

Remember what 'REAL' Opera 12 did in its times comparing to Chrome or Firefox? It loaded pages faster, used less memory, was most standards compliant and also came with bundled torrent client, and mail client and RSS client and ... and having 100+ tabs opened DID NOT EVEN SLOWED IT!

... and guess what, both Firefox and Chrome had more users while Opera had about 4-5%.

It did not mattered if it was faster or better.

Currently Opera is just a Chrome with different skin, so I moved to Firefox with Midori and Iridium as 'backups'.
