Login for Gmail long-in NEXT button no longer responsive after installing latest Firefox 62. I usually have gmail account set to always be logged in. I signed out then attempted to sign back in. I typed in my username and click NEXT but this button is NOT responding anymore. So now I can't log into gmail with Firefox 62 on iMac. I tried to open a “private” window in Firefox (first time using this) and the NEXT button in Gmail works and allows me to log in (I can see the indicator scroll and everything functions) , but in standard browser this button is unresponsive. I tried changing tracking, pop ups, added exceptions to gmail …. nothing fixes the issue. I cleared all my cookies, clear cache (now I have to re-authorize or re-validate my computer for all my banking & credit card access for payments, and everything, etc … big pain in the ass … thanks Firefox) . Why does NEXT button (or these controls) only work in private window but not in standard ?????? I also noticed recently that some other sites have had dome buttons that aren’t recognized after clicking. iMac with Sierra 10.12.6 32gb ram, worked perfectly until I logged out and needed to log back in.
