This is no longer a bug. I'm keeping the gist for historical reasons, as it helped to get it fixed. Make sure to read the notes by the end of the post.

How to remove hide the select arrow in Firefox using -moz-appearance:none;

TL;DR (or, the fix)

1. Set -moz-appearance to none. This will "reset" the styling of the element;
2. Set text-indent to 0.01px. This will "push" the text a tiny bit^[1] to the right;

Setting up a SSL Cert from Comodo

I use Namecheap.com as a registrar, and they resale SSL Certs from a number of other companies, including Comodo.

These are the steps I went through to set up an SSL cert.

Read Me

In order to access a server hosted within a vm (guest), for development purposes from the host OS, which is restricted to same origin / localhost only requests, I set up a siple nginx reverse proxy to forward my requests.

Steps

1. To install in a Windows VM, download and install nginx from the current, stable release; I installed to C:\nginx\
2. Edit the <install path>/conf/nginx.conf file with the marked changes in the file of the same name in this gist.
3. Start the nginx executable, located in your install path. There are service wrappers for Windows, or you can just kill the process to stop the nginx instance.

Commands for Windows
