Firefox 1.5 No Longer Supported

For those who still using Firefox 1.5 for a reason or another, be sure to switch to Firefox 2 as soon as possible. The reason is that Mozilla just announced that updates for Firefox 1.5 will be discontinued around mid-may of this year. The development in the future will be more focused on making Firefox 2 better and of course getting ready for the next generation of Firefox version 3. Source Mozilla Developer News
