Firefox is slow if automatic detection of proxy is on, but there is no proxy

[PeterPall]

Binary package hint: firefox

How to reproduce the problem:
- Connect to a network that doesn't provide a http://wpad/wpad.dat file with proxy settings
- Go to Edit/preferences/Advanced/Connection settings and turn on automatic proxy detection

From now on Firefox 4 tries to download the proxy settings from http://wpad/wpad.dat every time you click on a link. And it every time waits for the timeout of the domain name server telling there is no http://wpad before proceeding to downloading the actual internet page.

Not really a bug, maybe. But makes surfing in the internet extremely slow and is at the same time hard to hunt down; Did never experience this with Firefox 3 but - did never actually connect the network before I am in right now.

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner.

Presumably this issue was resolved some time ago and this bug report can now be closed. I'm changing the status to "Incomplete" to allow this report to expire in the absence of any further comments to confirm that the issue as reported still exists.

Thank you for helping make Ubuntu better.
