I read the note and it is so stressful to follow
It has lots of topics discussed.
I can only see the name Firefox esr 45.x and 52.x?
So I will presume 53.x is not supported?
Please check the below blog by Mr. Stevenchan, where mentioned about Firefox versions and jre required for EBS R12.1 and R12.2
Please check the section Certification Matrix for Firefox Browsers in Note R12: Recommended Browsers for Oracle E-Business Suite (Doc ID 389422.1)
So I will not set our firefox to auto-update anymore?
You can have auto update still turned on. Just uninstall the existing Firefox and install the ESR version.
I thought firefox and esr are one?
If I uninstall firefox, it will uninstall ESR as well?
Nope, they are 2 different types of releases. Everyone will be on regular firefox upgrade version except EBS and some enterprise content users will be on firefox-esr channel.
