MultiFireFox 2.0

Given the fact that lots of folks are downloading FireFox 3 as of late, I thought this might be a good time to highlight MultiFireFox 2.0. MultiFireFox 2.0 lets you run up to 5 versions of FireFox side by side.

Why would you want to do this? If you're a web developer you probably want to check your work in FireFox 2 as well as 3. MultiFireFox also lets those of you who don't want to jump into the new version of FireFox get your feet wet with the new hotness (or should that be the 'new wetness?'), but keep FF2 close at hand.

MultiFireFox 2 is free, so you can't beat the price and runs on OS X 10.4 and above.

Hi! Version 2.0 (006) is stable on my Powerbook G4 17" with OS X Tiger 10.4.11, whereas Version 2.0 (007) aborts.

Wonderful app, very useful. I'm experiencing a weirdness with it, though. Every time I start Multifirefox and choose my profile, Parallel Desktop is launched as well with a Windows version of Firefox which is on it. Anybody else experienced this? Why would something like this even happen?

Tried to give this a shot...looks promising, too. On my 10.5.3 machine, I can't get past the "You need to create a profile!" AlertSheet. Clicking the button does nothing, hitting return does nothing, and then I have no choice but to quit. No crashes or anything, it just won't let me get anywhere.

P.S. litmusapp gives me nothing - I need to test my local machine, primarily for intranet web applications - not public, static pages.

In case anyone else runs into this issue, I got it working by manually creating new profiles (run /Applications/Firefox.app/Contents/MacOS/firefox -ProfileManager to start the profile manager), and then moving my copies of Firefox directly into the /Applications directory (I generally separate things out when I can...lots of apps).

To all those that had crashing issues, please try the download again - after a few people were kind enough to provide crash reports and copies of their "profiles.ini" files, and according to all who tried it, the newest version 2.0.006 no longer causes crashes. 2.0.007 is on its way out soon as well to fix a minor bug.

Also, please do not delete Firefox 2 or 3 or anything else for that matter. I assure everyone that MultiFirefox does not delete anything, nor write to any files. Everything is opened in read-only mode.

So please do not assume that for a second that if you have an issue, you should delete everything on your machine. (By the way, if you delete Firefox with AppZapper, it will delete all your profiles as well, which hold bookmarks, etc.)

Best regards,

Dave

I don't know if keeping Firefox 2 around is going to be that much of an issue. It's not like IE6...new installations of Firefox 2 are only going to get rarer.

multifirefox sucks... i just had to delete firefox 2 and 3 completely and lost all of my bookmarks and data.

i just redownloaded ff3 and it wont launch, it says that firefox is already open even though i used appzapper to delete ff2,ff3, and multifirefox...

DO NOT DOWNLOAD MULTIFIREFOX IT WILL SCREW YOUR MACHINE BADLY!!! TUAW TAKE THIS DOWN, ITS CAUSING CATASTROPHIC ISSUES AND DATALOSS!!!

Nice app, but annoying that it asks to check for updates each time you start. And it's still impossible to handle the "default browser" which is currently my biggest firefox annoyance. Links from apps will simply appear in a semi-random firefox instance

Sorry, that's

/Users/username/Library/Application Support/Firefox/profile.ini

where "username" is your profile name in OS X.
