Hello! Your problem is very likely not caused by Firefox itself As far as I know, Firefox itself does not have the function of automatically refreshing tabs. Your situation is most likely due to an issue with the Tab Reloader extension you are using. If you have recently updated Firefox, your extensions may not be compatible with the latest version of Firefox or may have been automatically disabled by Firefox (most likely due to lack of signature authentication). So, please check if your plugin is the latest version and see if it is enabled. Also, check the plugin's blacklist and auto refresh switch (if any) Hope to help you！

Thank you for this non-answer.

Are you saying there is a smorgasboard of tab reloader extensions to use with Firefox? Where do I find this cornucopia?

Thanks. AR
