Like the title states, whether it be the search bar, url bar or any other text field the first key stroke of input is not registered and doesn't display. Once I've begun to type the missed stroke happens and then all is fine until I pause typing for around 30 seconds then the missed stroke happens again, otherwise I can continually type with no issues. This began a couple months ago and I assumed it was the old keyboard I was using so I bought a new one and the problem still persists. This issue is exclusive to Firefox and no other program or browsers on Windows 10. Firefox is fully updated, Version 94.0.2 (64-bit) at the time of writing this. I have "refreshed" Firefox and removed all add-ons etc. and the problem still exists. Thanks.
