As of 17th of June, 2008, Firefox 3 is now available on mozilla.com.

I just installed it a couple of hours ago, and so far, I have a very good impression about this new version. It seems to be pretty fast.

The only thing I hate with upgrading is that you will always have to wait until all your beloved addons will be updated and working again. Some can already be tweaked a little and will then work with FF3 - unfortunately, some won’t… I guess I will have to wait a little longer.

At least, an upgrade is always a chance to get rid of old addons that you hardly ever used.

OK, here is a way how to get some of the old addons working with FF3:

• Download the XPI installation file of the addon to e.g. your desktop.
• Open this file with your ZIP application.
• Within your ZIP application, open “install.rdf” to edit.
• Look for em:maxVersion=”…”.
• Change it to em:maxVersion=”3.0.0.*”.
• Let the ZIP application update that edited file in the archive.
• Leave your ZIP application.
• Drag & Drop the XPI file onto Firefox.

For me, it worked at least with the addons Smart Digg Button and Tab Preview.

More updated news from 2008-06-24:
Dust Me Selectors is now compatible wih FF3 and seems to finally work with Google Sitemap XML files!

[Update from 2008-06-25]
I let Dust Me Selectors examine my website by spidering the sitemap - strangely, it marked twice as much posts as “spidered” as there actually are on my blog…???

Furthermore, I had to slightly alter the sitemap’s XSL stylesheet. I am using the Google Sitemap Generator plugin for WordPress. In the XSL file - that the generated sitemap.xml file links to - there are also links to Google, Yahoo, Sitemaps.org and the author’s blog. If you leave them there, they will also be spidered…???
