Status: RESOLVED DUPLICATE of bug 652928

(Core :: Networking, defect)

Description

[bigbadabook]

Attachment: log.txt

User Agent: Mozilla/5.0 (Windows NT 5.1; rv:17.0) Gecko/20100101 Firefox/17.0
Build ID: 20121128204232

Steps to reproduce:

1) start firefox in safe mode, with all add-ons and extensions disabled
2) go to tools>options>advanced>network>settings, set socks host=127.0.0.1, port=65535 (where there is no server running), version=socks v5, click ok, click ok
3) visit http://www.google.com/, receive an error message "The connection was reset"
4) go to proxy settings, set host=127.0.0.1, port=7070 (where a ssh tunnel is listening), version=5
5) visit http://www.google.com/, same error message "The connection was reset"
6) visit http://en.wikipedia.org/wiki/Special:Search, page displayed ok
7) revisit http://www.google.com/, same error message "The connection was reset"



Actual results:

i suspect that bug 233811 was never fully resolved
it seems to affects all firefox versions from 4.0 through 17.0.1
the site in step 3 (google) got stuck with the wrong proxy settings
but in firefox 5-12 at least i can use step 6 to "persuade" firefox to use the new proxy in step 7
btw going offline/online does not work



Expected results:

firefox should have used new settings (127.0.0.1:7070) for http://www.google.com/ in step 5

I tried to reproduce this on Firefox 17.0.1 on Windows XP and Windows 7. 

I could only get the message that "The proxy server is refusing connections" every time i tried to visit www.google.com after changing the proxy settings as suggested in steps to reproduce.
