While browsing the FTP for Firefox nightlies, I found that they now have Firefox 3.0 Alpha 1 on there. Many people are going to say “wait, Firefox 2.0 hasn’t been released”. Yes, you are correct, but that doesn’t stop them from working on future versions of the browser. Just like Microsoft is working on the next version of Windows (named Vienna) while Windows Vista hasn’t even been released.
The links to download Firefox 3.0 Alpha 1 are below, but I highly recommend that you use the Portable version because you won’t have to install anything and the profile is kept separate from your main Firefox installation. There have been many known instances of crashing as well, but the memory usage seems to be pretty low. I have read in various locations that there are going to be memory leak fixes for version 3.0 that are not going to make the 2.0 release, so that could be the reason.
What is different from Firefox 2.0 Alpha 1? Well, besides the low memory usage, I haven’t noticed much. I have found that some of the Bookmark features are now actually functional, but other than that nothing too special.
All you have to do is download the Portable Firefox 3.0 Alpha 1 file below. Then you unzip the file and browse for the file PortableFirefox.exe. Just execute that file and you will be running Firefox 3.0 Alpha 1! The profile is kept with the PortableFirefox folder so you don’t have to worry about messing up your other profile and the uninstallation process is simple…just delete the folder!
This is by no means designed to be a stable version of Firefox. It is purely for testing which is why I have put together the Portable version so that you can play with it and then delete it, without having to worry about messing up previous installations of Firefox.
