Firefox 42: How to install unsigned addons on dev/nightly builds

While it's a major improvement on the more sluggy Firefox builds, it does however add a slight inconvenience for developers by restricting addon installations to signed ones. In my case, it was Firebug 3 alpha.

If you find yourself needing to install an unsigned addon, you can quickly do so by:

  • Type "about:config" into your address bar
  • Confirm OK "I'll be safe"
  • Filter to find "xpinstall.signatures.required"
  • Double click it to set the value to "false"

You shouldn't need to restart for this to take effect. Try installing the addon again, it should work this time.

Fix for installing unsigned add-ons in Firefox Dev and Nightly

Windows: Uninstall "Get Windows 10" notification tray icon

It's nice that Microsoft has gone out of it's way to promote their new operating system, but I would have greatly appreciated a "don't remind me again" option.

Right clicking it didn't show anything useful either.

After checking "Windows Update" history for recent updates, lo and behold I found KB3035583 "Update enables additional capabilities for Windows Update notifications in Windows 8.1 and Windows 7 SP1", which is a sneaky way of saying advertisement.

How to get rid of it?

  • In Windows Update, click on "Installed Updates".

  • Sort it by date and find KB3035583 under "Microsoft Windows".

  • Select it and click uninstall.
  • Click yes to confirm.
  • Once it's done, reboot for it to take effect.
