Reproducible: Always Steps to Reproduce: 1. Create a new profile. 2. Open Preferences, close them. 3. Exit Mozilla. 4. Enter Mozilla again. (note: if it doesn't happen on first run, just repeat it few times) Actual Results: Preferences window has a rather strange too small width. Expected Results: It should remain the same.

This is how preferences window looks after that transformation.

I see exactly the same preference window as the attachment on Linux trunk 2004030508, and I can't see any connection to bug 236107.

I had this happen to me yesterday with a 20030305 build, but I could fix it by removing the XUL.mfasl file in the profile directory. It's a cache, so it will be recreated again.

This looks like a bug 236467 dupe. Deleting XUL.mfasl works for me too.
