Steps to reproduce the bug

1. Go to Firefox
2. Go to a website that that browser would consider a webapp (such as https://www.wuxiaworld.com/ )
3. Turn off the internet on the phone via the quick drawer
4. Refresh the page so Firefox would display "Looks like there's a problem with your internet connection".
5. Click on the tripple dot menu & there click on Add to Home screen
6. In the popup whether we rename the bookmark or not the bug will sill occur, just click on "add".
7. Either crash or nothing happens

Expected behavior

Expected behavior is to get a bookmark on my home screen, similar to how it actually works fine for regular websites without the force offline workaround.

Actual behavior

Either nothing happens, or there is a crash.

Additional information

Why am I doing this?

I want to make a specific bookmark on my home screen that points to a specific place within a "webapp" type webpage. The workaround for this on Firefox mobile (& ios safari as well btw) is to turn off the internet & refresh the page before making the bookmark, otherwise only the intro page of the webapp can be bookmarked.
