Hi, sorry so long. You have not provided enough information for us to do anything with to make informed reply to you. Can try this as there appears to be an issue that only affects users who have turned off Cleartype Font rendering within their Windows Settings. So a workaround for the moment would either be to turn Cleartype back on or disabling hardware acceleration in Firefox: https://support.mozilla.org/en-US/kb/performance-settings Please let us know if this solved your issue or if need further assistance.
