Bug Description

expected result: once i installed chromium-browser, i wanted to make chromium-browser the default browser.

steps to reproduce:
menu> preferences> Default applications for LXSession> Launching applications tab> Webbrowser menu> change Firefox (default after installation) to Chromium.

Confirm pressing ok button to make file associations valid.

close Default applications for LXSession.

now click at the Web Browser icon located at the lxpanel, right beside pcmanfm icon.

note the Web Browser is still launching Firefox, so Default applications for LXSession changes are not working.

workaround from CLI:
sudo update-alternatives --config x-www-browser

and choose chromium. now the Web Browser at the lxpanel is launching Chromium.

reverse test:
Now that Chromium is the default browser, try to open Default applications for LXSession and change Chromium to Firefox. Confirm file associations again and close Default applications for LXSession.

now click at the Web Browser icon located at the lxpanel, right beside pcmanfm icon.

Chromium is still the default web browser, so Default applications for LXSession changes are not working either.

Have you logged out and back in again after trying this I think you need to do that for lxseisson defualt changes to take effect. I think for that to take effect to get the browser button on panel you have to click the set debian default program under the more button. The browser quick launch icon in the panel basically runs the command x-www-browser which is set by setting the debian default. Thing is on most 768 pixel high screens most of the other buttons for set debian defualt is off the bottom of the screen by bug but not for the browser supsringly. Although the debian defualt unfortanetly is system wide.

if you are using x-www-browser, yes you need to also do the debian associations. You need to click on "More" button and use "Set debian default program", that will make the appropriate associations.

I had both firefox and chromium already installed before installing lubuntu-desktop.

After installing lubuntu-desktop (which is coming along nicely by the way), chromium was the default browser by using the icon next to the "start" menu.

I tried changing this to firefox, and the preference shows that firefox is saved as my default browser. However, each time I click the web-browser launch it still launches chromium.

As a work-around, I saved a firefox launcher to my desktop, and then tried to drag and drop it to the quick-launch bar, but apparently dragging and dropping to the quick-launch bar isn't supported.

I like how lean lxde runs. Use to, the reason I wouldn't use LXDE was mainly due to it not having easy setup for multiple monitors (use to, if you did set this up, the setting would not persist to the next login -- now it does so that great).

I'll use lxde as my go to desktop as soon as I find a vertical launcher bar that acts like Unity's on multiple monitors and workspaces. Wow lxde is fast and lean!
