471659 - Mail not viewable via javascript, works in 3.0.5

Status: RESOLVED DUPLICATE of bug 462428

(Firefox :: General, defect)

Description

[Alfonso]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1b2) Gecko/20081201 Firefox
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1b2) Gecko/20081201 Firefox/3.1b2

I am able to use the javascript for my Windows Live email account due to the javascript not wanting to activate. It tends to stay with the box in the corner that says "Loading...", while not initializing. It works perfectly in 3.0.5. I double tested and ensured that JavaScript was enabled and that my security settings allowed the scripts needed in 3.1b2 but still to no satisfaction. 

--Possible Fix--
I had to modify the 'about:config' file so that Windows Live could recognize the browser. Had similar effect on Linux, when there was incompatibility issues with Windows Live Mail. Suggest changing the default User Agent to 'Firefox' instead of 'Firefox/3.1b2'


Reproducible: Always

Steps to Reproduce:
1.Open Windows Live Mail
2.Go To Inbox
3.Attempt To View Email
4.Open 'about:config'
5.Modify general.useragent.extra.firefox from 'Firefox/3.1b2' to 'Firefox'
6.Repeat Steps 1 through 3
Actual Results:  
A box in lower left corner stating "Loading..." appeared and the inbox would not update the main page to show the message. After modifying the 'about:config' it returned to normal, and I had no problems viewing emails.

Expected Results:  
A message should have been shown like usual, without having to modify the 'about:config'.
