Status: RESOLVED DUPLICATE of bug 347643

(Firefox :: General, defect)

Description

[william drescher]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.5) Gecko/20060719 Firefox/1.5.0.5
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.6) Gecko/20060728 Firefox/1.5.0.6

After auto upgrade to 1.5.0.6 Firefox is dumb and blind to the internet.  It can not find any url, whether it is given as a domain or as the IP address if it is beyond our NAT router/firewall (Netgear FVS318).  

After reinstalling 1.5.0.4 Firefox works just fine without any change in firewall/router configuraltion.  From that computer nslookup and ping of outside addys work find as does (shudder) MSIE.

I downloaded the 1.5.0.6 version twice to check for corruption - no difference

Reproducible: Always

Steps to Reproduce:
1.install 1.5.0.6 downloaded from http://www.mozilla.com/products/download.html?product=firefox-1.5.0.6&os=win&lang=en-US

2. 
3.

Actual Results:  
when it opens, it can not even find the "you've upgraded" page

Perhaps your Firewall has not been configured to allow Firefox 1.5.0.6 (the new version) to access the internet?  Please check your Firewall settings, and if it was a problem in your Firewall, this bug is not appropriate for Bugzilla and should be marked INVALID.
