Сравнение браузеров Firefox 2, Internet Explorer 7, or Opera 9

Интересный подробный обзор сравнивающий функциональность основных браузеров. Например:

With no pages loaded, and with no bookmarks, and otherwise with default download settings, here was the memory use for each of the browsers:

Memory Usage in MB (no pages loaded)
Firefox 2 Beta 1: 42
Internet Explorer 7 Beta 3: 24
Opera 9.0: 53
IE 6.0: 17
Firefox 1.5.0.4: 17.8

We also tested memory use on the browsers with a bunch of tabs loaded. We used the same group of tabbed pages on all of the browsers—ExtremeTech home, Yahoo, PCMag.com, YouTube, BBC World, and Flickr (with the same picture showing). With this tab load the results were as follows:

Memory Usage in MB Loading Six Tabs
Firefox 2 Beta 1: 73
Internet Explorer 7 Beta 3: 70
Opera 9.0: 52
IE 6.0: 155
Firefox 1.5.0.4: 56

Disk usage for each was as follows:

Disk Usage
Firefox 2 Beta 1: 18.8MB
Opera 9.0: 20.7MB
IE 6.0: 1.9MB
Firefox 1.5.0.4: 18.6MB'
