Firefox Quantum keyboard and mouse delays
Firefox browser recently released version 57 code named Quantum and touted it as “fast for good”.
Well, my experience was less than impressive, with constant mouse and keyboard delays, but rest assured, there is a very easy fix.
How to Fix Firefox 57 slow and laggy input performance
- enter about:config into the firefox address bar (confirm the info message in case it shows up)
- search for the preference named accessibility.force_disabled. double-click it, change its value to 1
- restart Firefox
That’s it! You should now have lightening fast keyboard and mouse response with no delays or lag.
