Firefox configuration tips

Using more than one firefox profile at once

Basically you need to start firefox with following parameters.

firefox --ProfileManager --new-instance

Then you need to customize firefox launcher on your panel. By default on mint this launcher already exists so you can modify using 'edit` (right click on firefox panel icon).

If it does not exist, just create a new launcher using add (right click on any panel icon).

Field Value Comment
Name Firefox Web Browser
Command firefox --ProfileManager --new-instance %u ««« You just need to edit that field
Comment Browse the World Wide Web

If you have to create a new launcher, you can find default icon for firefox here : /usr/share/icons/Mint-X/apps/96/firefox.svg

First check which application handle types text/html, x-scheme-handler/http and x-scheme-handler/https

Checking in global configuration:

cat /usr/share/applications/defaults.list | grep 'html'
cat /usr/share/applications/defaults.list | grep 'http'

Checking in user configuration:

cat ~/.local/share/applications/defaults.list | grep 'html'
cat ~/.local/share/applications/defaults.list | grep 'http'

if file does not exist, it mean user use global configuration.

It should be firefox.desktop

Then check how firefox.desktop
