I'm not sure what you've already changed mhbell, and I'm only familiar with the defaults (haven't changed anything drastically, as I'm still playing with "stock" items and monitoring long-term stability), but there's a setting in LXQt Session Settings>Default Applications that you can select default terminal emulation and web browser with pull-down menus, or by search for the desired cli/command.
Although, as I type this, I'm noticing that qupzilla is the default web browser (with firefox as a pull down choice), but there's no qupzilla in my program menu. Firefox is the only browser on my Siduction LXQt version: up-to-date Patience. So either I've found a bug, or this isn't the place to change that setting. Dunno...
I finally had to use drastic measures. I removed Firefox Completely including all conf, and data files for Firefox. at first I tried just changing the name in Firefox, but it just installed a fresh version on boot up. So I removed it and now Chrome works fine and is the default.
