Description

[Egor Starkov]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.4) Gecko/2008102920 Firefox/3.0.4
Build Identifier: 

Browser stalls until any event happen in system. It happens because mayWait flag is TRUE in nsAppShell::ProcessNextNativeEvent and core goes to idle loop. Backtrace is in attachment.
mayWait flag is FALSE in nsThread::ProcessNextEvent but after it is lost and not handled, so it becomes TRUE. It happens because mayWait is not passed as parameter and default parameter is used.

Reproducible: Sometimes

Steps to Reproduce:
1. open browser
2. type 'g' in address bar
3. press enter
Actual Results:  
broser stalls sometimes and continues loading after some events like clicking

Expected Results:  
browser should load page immediately

Here is the GTK workaround  for this problem.

We are pushing event into queue if there are no any events and myWait = 1.

The behavior you're describing, where a web browser stops loading if no events happen in the system, could be due to various factors, and it's important to investigate the specific circumstances and settings on your device to understand and address this https://spendbillgatesmoney.net/ issue.
