Allow localhost/insecure websites to access webcam/microphone on Firefox

On my daily development I came across the issue navigator.mediaDevices is undefined when testing a website I’m developing on Firefox browser. While the fix for Google Chrome is widely known, I didn’t find anything about Firefox and decided to dig deeper myself. Turns out the fix is pretty simple.

  • On the address bar of Firefox type about:config
  • Accept and continue
  • Search for insecure
  • Set media.devices.insecure.enabled and media.getusermedia.insecure.enabled flag to true

That should do it!! The next time you open your website, Firefox will ask your permissions for webcam/microphone.

Compiling and Serving Assets (JavaScript/CSS) in Production Environment -Rails 6

In order to server assets in Production environment; assets are first compiled and put into /public/assets directory. So, first you need to run the following command to compile the assets.

RAILS_ENV=production rails assets:precompile

It is encouraged to serve static content using NGINX/Apache. But if you want rails to serve the contents add/modify the following line on production.rb

config.public_file_server.enabled = true

In case you are facing anomaly and confident your code is correct then try clearing the cache using

rails tmp:cache:clear
