Internet Explorer 7 will finally bring IE into the modern world, with tabbed browsing, and extra security. But what will it mean for Firefox?

One might expect it to be bad news for the open source browser. After all, a significant number of people have switched to Firefox for its tabs and security. So won’t the IE update be bad news?

A prominent Firefox evangelist, Asa Dotzler, thinks not. He told ZDNet UK that IE 7 will be a boost to Firefox popularity. Why? IE 7 won’t work on Windows 2000 machines, but the publicity around IE 7 will mean businesses will want to get tabbed browsing and extra security. Because 50% of businesses still use Windows 2000, Dotzler says, they’ll turn to Firefox.

He may be right. But that assumes that Firefox gets its act together better by then. Updating Firefox has always been an iffy proposition, fraught with a variety of minor “gotchas.” The most recent update was even more problematic — it broke some extensions, and contained at least one security hole as well.

So here’s hoping that Firefox does a better job of updates. If it doesn’t, it will end up just one more interesting but largely forgotten browser, rolled over by the IE juggernaut.

How do you think IE 7 will affect Firefox?
