431963 - [RFE] Accessing network folder on bad connection hangs Firefox

Status: RESOLVED DUPLICATE of bug 349733

(Core :: Networking: File, defect)

Description

[Biju]

At present if you try to access a network folder and if there is network issue it hangs Firefox for a while. If it is a large network, like a co-operate network (WAN) it may take more than 30 seconds to respond with "File Not Found" error.

I wish access to file:///// should behave similar to http://
ie, allow tab switching or accessing Firefox menu while trying to load the page at a slow network folder.
Or in other words file:///// protocol should be asynchronous.

Steps to simulate error:-
* start Firefox on windows PC connected to a network
* goto firefox address bar
* type an invalid network address like
  \\adsdsdasd\asdsd\
* press enter
* try to access firefox menu
  Result : firefox dont respond for few seconds
  Expected : firefox menu should open immediately 

* click stop button
  Result : stop button is grayed out and dont respond for few seconds
  Expected : stop button is active, and allow user to click and stop button
 
* check Activity Indicator
  Result : Activity Indicator is grayed out
  Expected : Activity Indicator is active

* try to switch tab
  Result : Firefox hangs and dont respond for few seconds
  Expected : user able to switch tabs
