Firefox can be virtually endlessly extended through all manner of extensions. But even without extensions, the browser has a plethora of settings that are not exposed through the Preferences panel and hidden away in the about:config system. When using Firefox, enter about:config (no "http://" or "www" in there) into the address bar, take heed of the sensible warning and take a look around. Many of the settings are there by default, or changed through preferences (anything that isn't at default value is displayed in bold) and still others have to be added manually. Most of these settings won't be very useful to the average user, but there are some hidden gems. Here's a few of my favourite ones.

And then Windows 10 Creators Update came out. Along with all kinds of improvements came the reset of all customisation to default settings (ugh!). This included resetting the MIDI output to Microsoft's default and underwhelming "Microsoft GS Wavetable Synth". I found my MIDI Selector tool was no longer completely effective on Windows 10 x64 and had a minor bug as well as some slight inefficiencies. Fixed version 1.0.1 has been posted on the tools page.

A cute new point and click adventure game was released through Steam last week. This particular adventure game is a bit different from most modern ones in that there is no speech, only about a dozen screens, and you play not as a person, but as a... film projector... walking around magically? This is Projector Face, by Fluik Entertainment.

HTTPS sites are encrypted with a public/private key pair, being vouched for in a certificate by having that certificate signed by a trusted CA. However, it might be possible that somebody generates a certificate for your domain and has it signed by a fraudulent or compromised CA. Protection against this is provided by use of HKPK. But what keys should be "pinned" and why? I've found information about this online to be lacking, so I did some research and here's the results.

Microsoft's Outlook.com is one of the largest email providers in the world and anybody who sends email to customers will encounter plenty of outlook.com, hotmail.com or live.com addresses. As such, Microsoft has to deal with a lot of spam for all those billions of emails it processes and sometimes the spam detection is a bit overzealous. It doesn't take much for your server's IP address to be blacklisted, or you might even inherit a blacklisting from the previous owner of the IP address assigned to your newly commissioned server. Then you get the 550 SC-001 error.
