Which browsers does JustOn support?
JustOn is built on and operated in Salesforce Platform, Salesforce's software development and operating environment. This is why JustOn is subject to the same operation and interaction requirements as any other Salesforce software.
Generally, you can access and operate Salesforce, and hence, JustOn, with any modern browser.
There are, however, a few limitations, depending on whether you use Salesforce Classic or Lightning Experience. For example, the support for Internet Explorer 11 to access Lightning Experience has been retired in 2016. Since JustOn 2.51 has switched to Lightning Experience as the primary user interface, using IE 11 to work with JustOn may cause problems.
