Adding 'qawanted' to see if anyone else can reproduce.

Unable to reproduce the issue on Nightly/15.0a1 2012-04-29 a Motorola Droid Pro ( Android 2.3.4) using several free proxy servers. 
Can you please provide more info about the proxy server used in order to try and reproduce the issue?

The actual result has changed and now connect but It just skip the proxy.

I have a small proxy made with nodejs, testing with native Android browser and Dolphin It shows me every request but with stable Firefox and Nightly It doesnt show a single request.

In Ubuntu:

1.- Install nodejs
2.- Execute in terminal: nodejs proxy.js
3.- Set the proxy on Android using the ip of your machine and the port is 8081
Ok, I can reproduce the issue.
Opera Mobile suffers from the same thing.

I guess proxy setting is called here:

I don't see any defines for Android for:

Perhaps this library is useful for getting the proxy server in Android?
Removing 'qawanted' per above comment

I have the same issue, except that my proxy is in the APN settings. The Android browser works fine. So I have no browsing on 3G.

And how do you download the add-on?

Note that it seems proxy support is known to be broken in Android pre-ICS, but this patch will at least get things working in for ICS and later.

nit: Log.d and use sentences:
                Log.d("GeckoProxy", "Failed to create uri from spec", uriEx);
                Log.d("GeckoProxy", "Failed to create uri from parts", uriEx2);

>+        Log.i("GeckoProxy", "no proxy for: " + spec +", " + "scheme" + ":" + host + ":" + port);

I'd rather remove this. It leaks the URL, which is bad for private browsing. Also, I don't think this is critical enough to log.

Looks OK to me

r+, but you should get a toolkit person to review the toolkit parts. I thought the windowsproxy/nsWindowsSystemProxySettings -> androidproxy/nsAndroidSystemProxySettings looked fine.

Still not working with a SGS2 with ICS.

This change is already on latest nightly right?

Didn't make it on today's as it landed after it was built. Check tomorrow's.
I just checked with the latest nightly on my SGS2 with CM9 (Android 4.0 base). And it works for both http and https.
