One (ahem) can argue that this is too much updating with very little time in between.
Because Firefox 6 is not a major overhaul, the reviews are sparse, but people are still expressing their opinions. Here are the highlights from users around the web...
Michael Muchmore of PC Magazine reminds us that although the update is not dramatic, there is much to appreciate. "In fact, a look at its complete change log reveals a significant total of 1,300 changes and fixes. One that end users may notice include URL highlighting, which, like Internet Explorer 9 and Google Chrome, shows the domain name in darker font than the rest of a page's address."
Here are reactions from the Twitterverse...
Twitter user @rem tweeted, "Firefox 6 highlights for me: server sent events, web sockets (albeit vendor prefixed) and dataList support."
"So...Firefox 6 is stupid fast," said Twitter user @beep.
Twitter user @igrigorik tweeted, "yay, Firefox 6 supports the latest Websocket spec, and finally added eventsource support - long overdue! downloading..."
