Precisely.  I use Firefox for surfing, but I also develop web apps and 
find the error console a useful tool.

The idea of eliminating synchronous requests seems to have a strong 
foothold in W3.org, Chrome and Mozilla so I'm looking for a simple, 
logical alternative to my usage.

Personally ... I think it is a bad idea and not a decision for browser 
developers.  Web designers should have the right to create a slow 
loading page if they so wish.
