Firefox has been updated to 1.0.5 – the release notes are available here – they are not very comprehensive and basically simply say:
Here’s what’s new in Firefox 1.0.5:
- Several security fixes.
- Improvements to stability.
I hope this version is more stable than 1.0.4 – I found 1.0.4 to be a memory and processor hog to the point where I would have to force-quit it around once a week (really annoying when you have several windows open containing many tabs).
