Recognize custom Firefox profile locations

[philnagel]

Environment

• Operating system (including version): macOS Ventura 13.3.1
• mkcert version (from mkcert -version): v1.4.4
• Server (where the certificate is loaded): n/a
• Client (e.g. browser, CLI tool, or script): n/a

What you did

Ran mkcert -install

What went wrong

The above command was partially successful but returned an error regarding Firefox:

The local CA is already installed in the system trust store! 👍
ERROR: no Firefox security databases found

I believe this is due to how this script (line 19) assumes Firefox profiles are always located at ~/Library/Application Support/Firefox/Profiles. However, Firefox supports custom profile locations. On my machine, the profiles are located elsewhere. Instead of assuming the above path, the script should check the file ~/Library/Application Support/Firefox/Profiles/profiles.ini, which has the following pertinent sections:

[Profile1]
Name=Work
IsRelative=0
Path=/Users/philna/firefox_profiles/phil_work

[Profile0]
Name=Personal
IsRelative=0
Path=/Users/philna/firefox_profiles/personal

I would normally submit a pull request, but I have never used go before so I am not sure it would be very elegant. I can attempt if desired.

+1 in linux environments, firefox-esr uses ~/.mozilla/firefox-esr/ and currently mkcert checks ~/.mozilla/firefox/

in general it would be good to allow the developers to override data. being able to manually provide things like profile dir and name of the CA would really help.
