Firefox 1.5 Beta

After having some performance problems with Firefox 1.07 (slow-scrolling text with the new design on Joel On Software), I opened Firefox 1.5 Beta and tried viewing the page with it. I found that not only was the scrolling issue gone in the beta, but that the time it takes to go back to a previous page is much quicker.

This is good to see. Firefox is playing a key role in moving from desktop applications to web applications. They have long been good about implementing new features, but with the current generation of web applications, a lot of work needs to be done on other things, like performance.

One thing that I see happening is Firefox dealing with lots of issues normally left to the Operating System. Firefox is no ordinary program – it’s a platform for running applications, and has to deal with lots of issues of being a platform. When many pages are open, memory management between different pages becomes an issue. Same with page histories, and making the back button instantaneous. I also see a lot of work to be done on isolation. I’ve had Firefox freeze a number of times with complicated JavaScript, CSS, or Flash. The obvious thing to do is to make Firefox do internally what the OS does when Firefox crashes, that is, isolate the crash to a single web page, the same way the OS isolates a crash to a single application.

I see a lot of exciting times ahead for Firefox.
