Good day,

Since updating windows 10 to version 20h2, Firefox is Laggy and never done this before updating windows10 to 20h2. I would seriously look into this as MS.Edge is working smooth but all other browsers are lagging. Microsoft has done something with the update which is making all other browsers lag except for theirs. This is unfair practice as we all like using Firefox and Microsoft wants to take the monopoly with Edge. Please Firefox Team resolve this issue or please look into it as i am not the only one experiencing this issue after updating windows 10 in recent days.

Can you provide us more details about your issue? Just saying it's laggy is not much to go on. What version of Firefox? Have you cleared your cached? Is it lagging when you first open the browser or on certain websites? Do you have the same issue when running Firefox in safe mode? My daily driver is Linux, but let me boot up my Win10 laptop to see if it's having issues.
