If anyone wants to try it

Windows - http://ftp.mozilla.org/pub/mozilla.org/firefox/tinderbox-builds/pacifica-mozilla1.8/firefox-2.0a1.en-US.win32.installer.exe

Mac  - http://ftp.mozilla.org/pub/mozilla.org/firefox/tinderbox-builds/atlantia-mozilla1.8/firefox-2.0a1.en-US.mac.dmg

Linux - http://ftp.mozilla.org/pub/mozilla.org/firefox/tinderbox-builds/prometheus-mozilla1.8/firefox-2.0a1.en-US.linux-i686.installer.tar.gz

Regular tarball in same root directory works. Unpack and run.

seems to hang a bit less under load.

uses your old profile just fine, tho some extensions wont work.

Wont hurt, just dont uninstall your old version as some stuff in Unbuntu is dependent on it.

How the hell are you getting it to run? It dont have it for me! I extracted everyting and found the firefox file but .....

If you grabbed the non installer version, just unpack and double click on the firefox icon. Make sure its permissions are set to be executable. Mine was out of the box.

This one worked for me: http://ftp.mozilla.org/pub/mozilla.org/firefox/tinderbox-builds/prometheus-mozilla1.8/firefox-2.0a1.en-US.linux-i686.tar.gz

Everything looks slightly different, must be the font

Extra tab closes are good  

Is there any next level shizzle worth installing this for? Buggy 1.0.7 is due an upgrade but a hog of an alpha isnt going to be worthwhile for surely?

hasnt crashed on me yet, just used it an hour or so though.

They moved the close tab button. Revelation of revelations.

Each tab now gets a button, but only the active one has a clitoral burnish to it, the others are greyed out.

I think its supposed to  have a phishing detector or something as well.

Other than that, not much different than 1.5 final that I usually use on my Dapper Drake.

Search in bookmarks is good. That in 1.5??

Search histry too
