Created attachment 8905063 [details] Default browser.webm User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:57.0) Gecko/20100101 Firefox/57.0 Build ID: 20170906100107 Steps to reproduce: Went into Preferences, clicked "Make Default" button. (Using today's Nightly build on Ubuntu GNOME 16.04.) Actual results: Nothing. See attachment. Expected results: Firefox should be set as default (or Ubuntu's dialog for setting the default browser should appear - not sure).

Ricky, you recently worked on the Make Default button. Can you look in to this?
Status: UNCONFIRMED → NEW
Ever confirmed: true
Priority: -- → P3
There is a similar issue on macOS. On Mac, the system native popup dialog of changing default browser will show behind the browser. However, this issue is happening on Linux. I'll take a look. Thanks
Vincent, I can't reproduce your issue on Ubuntu 16.04. > Build ID: 20170906100107 According to your Build ID, you're using the build from last week. Could you try the latest one again? P.S. On Linux, Clicking "Make Default" button will set Nightly as default browser immediately without prompting any system dialog.
Ricky, I regularly install the updates, and every time it restarts the dialog pops up again. It also still says "Nightly is not your default browser" even though I click "Make Default" every time: https://imgur.com/a/aKWQE Could it have to do with this being regular GNOME, rather than Unity?
Jared, It seems like a platform specific issue only happen on Ubuntu GNOME. I'm afraid I'm not the best person can handle platform issue. Do you know someone who can help us?
@ricky, I think it was one of your patches that made this button show up on Linux? Can we just revert that part of your old patch?

Jared, my patch in bug 1389377 was aiming at introducing `Exponential backoff mechanism` for updating button status. The "Make Default" button always show up on Linux as it is. As a result, I suspect the issue might be platform relevant.
Okay, thanks for the correction.

Unfortunately, I cannot reproduce your issue even thought running on Ubuntu 16.04 GNOME with using Nightly build 20170906100107. I've tested that the Make Default still works properly on Ubuntu 16.04 Unity & KDE, and even work on GNOME (GNOME Shell 3.18.5). Make Default button is using `gconf`  to set default browser for user. It seems like this code hasn't been changed for a while. I've no clue why it only cause in your machine.  http://searchfox.org/mozilla-central/source/browser/components/shell/nsGNOMEShellService.cpp#204-247 Jared, do you know someone from platform team who is familiar with Linux has time to take a look?
Created attachment 8913160 [details] dconf-editor focused on /org/gnome/desktop/applications Thanks for checking Ricky. It sounds like a similar setup: I'm on Ubuntu 16.04 with gnome-shell 3.18.5 as well. A few more things I checked: - I just tried to click a link from within LibreOffice and one from GNOME Maps, and both _did_ open in Nightly. - Then again, when I closed Nightly and opened regular Firefox, the link opened there. - Stable Firefox listed itself as not being default. After clicking the button to set it as default, it did. Then clicking that button in Nightly didn't change that. - I'm not sure if gconf is still a thing, but in any case, in dconf editor I did not find a setting for default browser. I've attached a screenshot, which does show defaults for calendar, terminal and tasks.
Mike, do you know who can take a look at this issue? (see also comment 9)
Hey karlt, are you still hacking on GTK stuff? Is this something we should point your way, or is there someone else we should forward this to?

karlt would be my choice too.
based on comment 12, remove whiteboard tag
I reset browser.shell.checkDefaultBrowser and wasn't able to reproduce with 57 beta. I reset browser.shell.defaultBrowserCheckCount, browser.shell.skipDefaultBrowserCheck, and wasn't able to reproduce with Nightly. Each time, choosing to make default changed, as expected, the output from gconftool-2 --get /desktop/gnome/url-handlers/https/command

I haven't seen significant changes in these files for years now, and so I don't know who to suggest. But it's hard to analyse without being able to reproduce. The code tries gconf before giovfs. Perhaps that should be reordered, or more likely gconf just removed, but I don't know that that is the cause of this bug.

Ah, yes, the stable build was provided by Ubuntu. I've now tried Mozilla's 56 stable and, indeed, I still experience this problem. That makes this less worrisome, I guess - perhaps they've just added some patches to make this work. Nevertheless, some more diagnosis. I just now noticed that, when I click the Make Default button, the following is output in the terminal: (firefox:17108): GLib-CRITICAL **: g_find_program_in_path: assertion 'program != NULL' failed Also, I did get the expected output from gconftool-2 (I'm on Developer Edition now): $ gconftool-2 --get /desktop/gnome/url-handlers/https/command /home/vincent/Downloads/firefox 56 stable/firefox-bin %s Furthermore, there are a lot of .desktop files for Firefox Developer Edition and Nightly in ~/.local/share/applications/, I presume for every time I pressed the Make Default button?
Currently (as far as i can tell) the 'Make Default' button: > edits the necessary entries in ~/.config/mimeapps.list > creates ~/.local/share/applications/userapp-Firefox-RANDOM.desktop works successfully for firefox binaries from mozilla ----------------------------------- (In reply to Vincent from comment #18) > Furthermore, there are a lot of .desktop files for Firefox Developer Edition > and Nightly in ~/.local/share/applications/, I presume for every time I > pressed the Make Default button? yes and you can remove them, for the one that is actually currently set as default look in ~/.config/mimeapps.list to complete desktop integration see: https://bugzilla.mozilla.org/show_bug.cgi?id=1427383 https://support.mozilla.org/en-US/questions/1164411#answer-978198
