Can I install Firefox 2 independent of Firefox 1.5 or will it automatically take all the installed extensions?

Firefox 1.5 is installed already on my PC if I install Firefox 2 will it take all the installed add-ons and extensions of Firefox 1.5 i.e will it upgrade existing Firefox 1.5? or do I have to install all the Add-Ons and Extensions again?

1. upgrades to systems usually remove the old one while it installs the new one. or we would all be losing our memory :).......
2. That depends on whether the add-ons have the support for Firefox 2. If it does, it will automatically update itself. If it does not, it would still be installed but unusable until the add-on has an upgrade to Firefox 2 compatability.
3. you can install it but dont install it to c:\program files\ mozilla firefox just in stall to c:\
4. As someone who has done exactly what you are after on a number of occasions (spent much time developing themes when I actually had the time), yes you can - I've had up to 5 separate instillations/versions installed at once! Just don't run then simultaneously! Each need to be installed in it's own programs folder (use the custom install option to do this). Would also advise to set up a clean profile to save profile corruption - open the run console and enter "firefox.exe -p" to open the profiles manager and create new profile. Is easy enough to switch btwn either. The link below explains how to set up a custom shortcut for each profile, so you don't have to always go through the profile manager to switch
