Status: RESOLVED INVALID

(Firefox Build System :: General, defect)

Description

[Heather]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.9) Gecko/20050711 Firefox/1.0.5
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.9) Gecko/20050711 Firefox/1.0.5

When I open Firefox, regardless of the page I visit, the javascript console
displays many errors, including the following warning: 

Error: this.docShell has no properties
Source File: chrome://global/content/bindings/browser.xml
Line: 0

I went into the chrome folder to try and look through the files. When I tried to
open the JAR files, the following error pops up:
Invalid or corrupt jarfile C:\Program Files\Mozilla Firefox\chrome\toolkit.jar
(filename is an example, happens with all files)

Reproducible: Always

Steps to Reproduce:
There are no steps to reproduce this, other than opening Firefox.

Actual Results:  
N/A

Expected Results:  
It should not open with errors.

This only just began a few days ago. I had installed an extension and then,
since I didn't like it, uninstalled it shortly thereafter. This issue may have
started just after that, but I can't be 100% certain.

Does this occur if you start firefox in safemode:

The error in the jsconsole is known, and your comments about invalid jar files
has nothing to do with moz (your windows file association is set toopen jarfiles
with java).

If you don't mind, what program/application should the jar files be opened with?
