Which browser should I use for AIM?
The standard major Internet browsers are supported by AIM in Classic - this includes Microsoft Internet Explorer 9, 10 and 11, Mozilla Firefox, Google Chrome and Apple Safari 5.x, 6.x and 7.x. You may use other unsupported browsers, but this will typically result in a higher number of errors.
AIM in Lightning is more limited with Internet Explorer, with Salesforce support for IE11 ending on December 16, 2017.
Our recommended browsers are either Google Chrome or Mozilla Firefox. These browsers perform the best in terms of speed, display, and errors experienced. We also recommend that you stay up-to-date with all new releases for whichever browser you choose to use.
