742394 - Firefox Not Keeping The Default Browser Setting for Linux 64-bit

Status: NEW

(Firefox :: General, defect)

Description

[Emerson1000]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:11.0) Gecko/20100101 Firefox/11.0 Iceweasel/11.0
Build ID: 20120330193039

Steps to reproduce:

If I ever let on Windows 7 another Browser besides Firefox 11 become the Default Browser, then Firefox will not keep my default setting ever again. I set it as default and when I ex out of Firefox , the next launch is asking if I want Firefox as my default browser. This goes on and on forevermore.
No Windows Problem. Same thing with Iceweasel 11 on Debian Squeeze.


Actual results:

I say Yes , but it does not stay. It stays until I go out of Firefox . I have not been able to find a solution ,therefore I believe it to be a bug. I have emptied all cookies , passwords , cache, and everything else and it does not work.
Purged and reinstalled Iceweasel 11 on Debian Squeeze. Same poor result.



Expected results:

Reproducible on:
Firefox 20.0 Beta 7 (20130325214615):Mozilla/5.0 (X11; Linux x86_64; rv:20.0) Gecko/20100101 Firefox/20.0
Latest Aurora (20130326042012): Mozilla/5.0 (X11; Linux x86_64; rv:21.0) Gecko/20130326 Firefox/21.0
Latest Nightly (20130326030941): Mozilla/5.0 (X11; Linux x86_64; rv:22.0) Gecko/20130326 Firefox/22.0

This is only for 64-bit version; works fine on 32-bit version.

Steps to reproduce:
I. 1. Start Firefox for the first time (or a clean profile)
   2. When asked to make it your default browser
   3. Click "Yes"

II.1. Start Firefox while other browser was previously set as default
   2. Go to Edit | Preferences | Advanced | Click on "Make Firefox the default browser"

Expected result:
Firefox should become default browser.

Actual result:
In both I. and II. cases, Firefox is not set as default browser.
