Mozilla has redesigned its official site to coincide with today's release of Firefox 1.5. Improvements in this version include:

• faster navigation back and forth in a browser session
  
• improved software and extension updates
  
• drag and drop support for tabs (previously available via extensions)
  
• enhanced pop-up blocking
  
• more customization controls
  
• a bunch more I haven't listed (full release notes here)

I've been using Release Candidate 3 for a week or so now, and it's noticeably faster and very stable. I highly recommend downloading the new version.

However, there are some issues with extensions and Greasemonkey scripts that I should mention. My next post goes into more detail...
