These release notes state:
Extended support for Firefox browsers. TestComplete now supports all current and future versions of Firefox. There's no need to wait for compatibility updates anymore - TestComplete will automatically work with new Firefox releases as they become available.

This Supported Browsers page still states:
Mozilla Firefox 91 - 115.10 ESR, 94 - 140 (both 32- and 64-bit versions)
https://support.smartbear.com/testcomplete/docs/app-testing/web/supported-browsers/index.html
When I try using Firefox 140ESR TestComplete still does not see objects.
Has anyone else had any success using newer Firefox versions? In particular the ESR branch?
