O/S is Windows Me with all patches and updates loaded.

Reproducible: Sometimes

Steps to Reproduce:
1. Launch Firebird
2. Go to any website with .pdf files for loading for viewing or downloading.
3. More often than not, system then locks up. Doesn't happen on same site with IE.

Actual Results:  
Tried "back" button/function...doesn't work.  System now locked up.

One should be able to view a .pdf file in Firebird or go "back" to previous
screen viewed without system locking up and having to reboot system.

Confirming this bug on Win XP SP1 with Mozilla 1.4 build 20030624.

Additional information:
I can reproduce this bug only if I the loaded pdf is NOT the first pdf I try to
view in this session.

Killing AcroRd32.exe in the task manager releases the lock in mozilla. 
After that pressing back and a new click on the pdf-URL loads the pdf as normal.

I assume, that the Acrobat-Plugin is not properly unloaded, reseted, etc. after
leaving the first pdf-file with the back button, which causes the
acroread-process to hang.
