In Firefox only, not in Windows in general, the browser randomly changes some settings. Shift +Ctrl bring it back
It's a really annoying inconvenience. It has been happening for few months now. Randomly, Firefox changes something and I need your help to stop or fix it. Some keys act like hotkeys (I think, don't use hotkeys), but a singe key press opens a new tab, or opens a download folder, each letter does something different, but I'm not pressing any other buttons together. Then a touchpad (usually in Youtube), opens a video in a new tab instead in current tab, that's how I usually notice Firefox changed it. Pressing shift+ctrl reverses it back to normal, but then, it can happen again few more times throughout use time.
The Windows hot keys are disabled.

Reinstall Current Release Firefox 56.0.2 with a Full Version Installer https://www.mozilla.org/firefox/all/
Alternatively you can get the new Firefox Version 57 from here : https://fileforum.betanews.com/detail/Mozilla-Firefox-for-Windows/1032985422/1 Note it will be on Mozilla's pages tomorrow or through update. But since having this issue and having to uninstall why not put 57 straight in. Note : Legacy Extensions will be disabled and or removed.
