I'm trying to test my app on older versions of firefox. My code relies on the browser version inside the user agent of browser:
console.log(navigator.userAgent)
I installed various older versions of firefox from this page (versions: 33, 34, 39, os: windows) and installed them but the user agent for all of them are Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:;secssobrowser) Gecko/20100101 Firefox/"
which doesn't include the browser version.
Does anyone have any idea why the browser version is not included in the user agent?
