451132 - Connection Settings: Doesn't display set proxies when multiple proxy servers used

Status: RESOLVED INVALID

(Firefox :: Settings UI, defect)

Description

[Owen]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1

After different proxies are entered for HTTPS, FTP, SSL, GOPHER and SOCKS, re-opening the Connection Settings dialog does not populate the proxy textboxes with the exception of the HTTP Proxy textbox.

This does not stop the proxy settings from working, they appear to simply not be loading into the Proxy fields after being set and the dialog reopened.

Reproducible: Always

Steps to Reproduce:
1. Open Firefox, click Tools, Options, Advanced, Network, Settings
2. Specify a proxy server and untick 'Use this proxy server for all protocols'
3. Specify a different proxy for HTTPS or any of the other protocols
4. Click OK
5. Click Settings again
Actual Results:  
HTTPS Proxy, FTP Proxy, SSL Proxy, GOPHER Proxy and SOCKS Host textboxes are empty

Expected Results:  
Proxy textboxes should be populated with the proxies and port numbers entered in steps 2-3. 

Occurs in firefox-3.1a2pre as well.

Seems to be a similar issue to Bug 321807, but that didn't occur in 3.0.1

Doesn't seem to affect 3.0

So, can you check about:config (search on "network.proxy."). Make some changes in the UI, see if they are saved in about:config, then look at the UI again.

Entered a proxy for ssl and checked about:config - it updated with the proxy I entered.

Going back to the UI, it left the field blank. Closing the UI and checking about:config again, the proxy setting was lost.

Okay, so if the prefs are in about:config, and you quit and re-launch, the proxy preferences should behave correctly... If this is not the case, I need to know.

So when you return to the UI, you see it is blank, and then you hit "ok", right? (This would have saved the blank values into about:config).

and now that I look at the code more... I think what I need is about:config for network.proxy.* after the first and second changes. I think there might be a bug in the dialog initialization code that I can't see from looking at the code and imagining the state model.

After further testing, I've narrowed this issue down to an issue on our desktop build, rather than a firefox bug. I have tested this on PCs with a plain WinXP build and cannot replicate the issue. 

Sorry for the trouble.

Owen, can you give me more info about the problem? For the other reports, we did find that it was windows-only, due to a bug in "instantapply", (which I don't understand very well).
