There is a bug in the search bar of Android Firefox 80.13
Click on the search bar of the Firefox browser, and enter a string of numbers with “.” in it, or a mixed input with English symbols [.], such as Firefox 80.13, and the search page will not open open.
Logically speaking, here should be the result of opening a search, not a web page.
I hope someone can see and give feedback to the engineer to fix it.
