Has anyone installed Firefox 23 yet on Windows 2000? It was on Mozlla's FTP servers hours ago. Firefox 23 does work with the current revision of UURollup v11 (released on 2013-02-23). However, what I'm seeing is that the Firefox icon logo now has a black background surrounding it. In Firefox 22, the background used to be transparent. Also, when you select Help > About Firefox in the menu, the Firefox text no longer appears. Is there a way to fix the issue with the black background surrounding the Firefox logo? By the way, I might have to provide screenshots for proof... Edit: I checked the website where it has the daily updates and found that Windows2000-UURollup-v11-d20130616-x86-ENU.7z is the latest daily UURollup release. However, I don't know if it's stable enough to use. Also, I checked the release notes and found that Mozilla developers updated the Firefox logo to use alpha transparent true colour icons for Firefox 23 and beyond, for which it displays a black background instead of a transparent one. I'm wondering if there are anymore updates to UURollup, btw.
