Firefox 4: First Impressions
March 24, 2011 – by Per Christensson
When it comes to Web browsers, I am partial to Safari, but I also use Firefox from time to time. I opened Firefox today and it politely informed me that version 4 was available, so I decided to upgrade.
So far, I am highly impressed with the new version. The page rendering speed is noticeably faster than Firefox 3 and the overall responsiveness of the browser is quicker. Plus, the user interface has been cleaned up and feels more intuitive. While I am not a big fan of tabbed windows, Firefox 4 also has some cool tab features. One that I really like is the "Pin as App Tab" command, which allows you to create small tabs for your favorite sites. This provides an easy way to keep your favorite sites open without taking up too much tab space. Another nice touch is when you type in a URL that is already open, Firefox jumps to the current tab rather than opening a new one. Finally, tab groups have been added, which allows you to organize open tabs into groups of related websites.
Regular visitors know that I have a passion for advancing new technologies. Therefore, I am excited to see that Firefox 4 is pushing the Web forward by supporting the latest HTML 5 and CSS 3 standards. It's great news for Web developers who have been waiting to make use of these new technologies. Unfortunately, Internet Explorer 8 still lacks support for HTML 5 and CSS 3, which is holding back a lot of websites from implementing these new standards. The good news is that IE9 will fully support HTML 5 and CSS 3. For Web developers like myself, that release date can't come soon enough.
