Safari is affiliated with Apple and I won't touch products of a company whose products and way of running business are antithesis to openness, freedom and hacker culture.
Chrome.. no special reason. I don't particularly like it, nothing I could point the finger at, but.. blah. Is there a way of disabling plugins in Chrome, as in: a placeholder is displayed on the page and the plugin is activated when I click the placeholder?
IE, on the other hand, has "suggested sites" feature which I'd like to test more. Maybe it helps me with discovering some new content on the net.
Or do you mean they don't bundle patented codecs like H264? They support HTML5 video just fine AFAIK.
Yes, via extensions and a native browser option
Yes, I use this all the time. it's built into the browser.
