Gone , gone. This seems to work well if there is a Firefox 57 compatible Extension. Can use google search terms : Firefox Extension <old extension name> Comparable

If want a Desktop one, i use this and is sorta like that program http://www.rainlendar.net/cms/index.php

Please let us know if this solved your issue or if need further assistance.

thanks for the tip. However I require all the data from Reminder Fox..... appointments, dates, etc....

reminderfox has created an .ics calendar file in your firefox profile folder that you can import into other calendar apps: http://www.reminderfox.org/documentation-user-guide-sharing-reminders/

I have had to revert to the previous version of firefox for this same reason why are we not warned that firefox reminder does not work in new version and why is it released before it does?This has happened more than once before.

I also went back to version 56.0.2 just to get reminder fox back. I don't know what they were thinking when they dropped it WITHOUT a warming. Sucks. Now I am going to be afraid to upgrade firefox. Reminder Fox is something I will want to keep around, works great.
