Well, on a whim I decided to download today's Firefox Beta 3 latest trunk (http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-trunk) and give it a whirl. And guess what? That annoying little problem with adding links to text under Blogger is now fixed. A lot of other items work well enough for me to use this version of Firefox 3 beta for the foreseeable future. One of the nicer touches is that Firefox 3 uses the same scheme (Nodoka) that the rest of the Ubuntu desktop uses. Look below at the tabs.
Now I just need to pay attention to the memory usage. Although to be honest memory usage has never been a big deal for me with Firefox 2.
To the Firefox 3 developers, thanks! This is (as usual) great stuff!
