441172 - Crash [@ nsACString_internal::GetReadableBuffer] on start-up, after installing Firefox 2 over existing Firefox 3 installation

Status: VERIFIED DUPLICATE of bug 423226

(Firefox :: General, defect)

Description

[Martijn Wargers (dead)]

My brother encountered this.
He wanted to try out the new Firefox 3, then he noticed some change in Firefox 3 that he didn't like, so wanted to revert back to Firefox 2.

Steps to reproduce:
- Install Firefox 3 using the default settings
- Install Firefox 2 using the default settings
- Start-up Firefox 2

Result:
Crash

What version of firefox 2 did he downgrade to. Connected to bug 423226 perhaps?
