*What can I do to prevent this from happening again?* Firefox suddenly today (4/2/2020) decides to go missing from my Windows 10 Start Menu.

I've been using Firefox as my default web browser on Windows 10 for a while now, and I've become used to launching it both from the Task Bar and the Start Menu (depends on if I'm currently wielding the keyboard or the mouse at the time I want to launch Firefox).

As of today, 4/2/2020, the Start Menu entry has completely disappeared. There is no "Mozilla" folder in the start menu nor is there anything filed under "F" for Firefox.

I tried to remedy this issue by right clicking my Firefox task bar shortcut and clicking "Pin to Start Menu" as a way to force my start menu to recognize Firefox when I start typing "Firefox" after pressing the Windows key.

What results instead is this god awful Hex number (see attached screenshot) that reads "W~E7CF176E110C211B". Clicking on this shortcut does absolutely nothing. Pretty sure I'm not supposed to see that, and that this is a bug that shouldn't be happening.

To make sure I'm not crazy, I again right clicked on my working Firefox task bar shortcut, and clicked on "Properties" (see attached screenshot). Nothing looks unusual there, so now I'm just at a loss as to **why** this happened, **how** it happened, and **What can I do to prevent this from happening in the future?**

I do not have this problem with any other application. No other application has just decided to disappear themselves from my start menu. No other application gives me some bullshit hex number in place of an actual app shortcut to an executable binary file that lives in Program Files (x86). I'd be a little more understanding if it was located in some weird ProgramData folder, but I'm just super confused as to why this happened, and I'm frustrated that I have to stop what I was doing to write this up.

That being said, I genuinely appreciate any preventative help that can be done to prevent this from happening in the future, even if I may be slow to respond (I will try really hard to not be slow to respond). Please help me from my nagging brain that is now considering moving back to Chrome so I can continue typing in the application name to launch from Start Menu as I am able to do with literally every other program.
