Google has said that IE7 would no longer be supported in its apps as of August 1 of this year. Users may find some features missing from their apps if they are using IE7 and the app may eventually not work at all anymore in this browser. Google said that it would also phase out support for Firefox 3.5 and Safari 3.
As a rule of thumb, Google apps such as Gmail, Calendar, Docs and Talk will only support the two latest versions of a browser, which would be IE9 and IE8 in Microsoft's case or Firefox 4 and 3.6 for Mozilla. Google justified this move mainly with the need to move to newer web technologies such as HTML5, which isn't supported by older browsers. "Older browsers just don’t have the chops to provide you with the same high-quality experience," the company wrote in a blog post.
Whether you like it or not, you will have to keep your browser somewhat up to date, if you want to use Google's apps. Chrome users, of course, don't have to worry as they are updated automatically, but this new policy could be a real pain in the neck, especially for IE users, who tend not to regularly update their browser.
