When I m using google doc or sheet to edit a document from google drive, I notice that my cursor will freeze for 5-10 sec from time to time. No issues with chrome on the same documents. I never had this problem until the firefox updates in the past few months. I have tried the usual steps such as disabling all plugins, start firefox in safemode but nothing works. The problem is consistent across all documents, even for new documents. Does anyone know of a workaround?
