Ubuntu 22.04 Firefox (snap) crashes on Ctrl+S

A lot of times while coding I press Ctrl+S to save Visual Studio Code and update live server (while watching on firefox the result). The problem is that when I'm focused on Firefox Ctrl+S pops up the Save Page window and (if I held Ctrl+S for more than a split second) it crashes (probably due to multiple popups becoming unresponsive). The mouse can't click to cancel the pop ups for saving the page nor interact it. I have to kill the firefox process and restart it. I've been looking into disabling Ctrl+S shortcut in Firefox with no success (extensions are deprecated or require too many permissions I'm not comfortable with). Would someone help me to disable Ctrl+S or enlighten me on how to not have firefox crash every time I accidentally press Ctrl+S? Thanks!
