Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7) Gecko/20040626 Firefox/0.9.1

When starting Firefox 0.9.1, 29 JavaScript strict warnings are found in
"[FirefoxDir]/components/nsExtensionManager.js" and one error is found in
"chrome://global/content/alerts/alert.js"

The warnings are all "redeclaration of variable".
The error is an uncaught exception (as follow):
Error: uncaught exception: [Exception... "Component returned failure code:
0x80004002 (NS_NOINTERFACE) [nsISupports.QueryInterface]"  nsresult: "0x80004002
(NS_NOINTERFACE)"  location: "JS frame ::
chrome://global/content/alerts/alert.js :: prefillAlertInfo :: line 69"  data: no]

Reproducible: Always
Steps to Reproduce:
1. Open Firefox 0.9.1
2. Open JavaScript Console
Actual Results:  
29 strict warnings and 1 error are found in Firefox's js files

Expected Results:  
No warning and error

"javascript.options.strict" need to be set as "true"
This can be changed using "about:config".

Works for me. I only see redeclaration errors, which I guess are perfectly valid
since the variable's passed out of scope. Are you reproducing this on a new profile?

hao2lian, you are right.
Just did a fresh install of Firefox 0.9.1 (profile removed) on Windows 2000 SP
4. Only strict warnings are found.

The error is most like caused by the Extensions that I installed?
FYI, the extensions are:
- All-in-one Gestures 0.11.1
- Web Developer 0.8
- Launchy 3.0.0

Hope it helps...

Just installed all the 3 extensions mentioned before on that newly installed
Firefox. Still no error found.

Maybe there is caused by the old 0.9 (not 0.9.1) profile.

The strict warnings in the EM are covered in Bug 249012, since you can no longer
reproduce the error I'll just mark this as a duplicate.
