Which Firefox version is compatible with Selenium 3.6.0

Selenium with Gecko Driver

Selenium Release Perspective :

Selenium v3.6.0 (Java) Release explicitly didn’t mention any dependency explicitly.

The last dependency explicitly mentioned by Selenium was for v3.4.0 which is as follows :

Geckodriver 0.16 is strongly recommended

GeckoDriver Release Perspective :

  1. GeckoDriver v0.19.0: Firefox 55.0 (and greater) & Selenium 3.5 (and greater)
  2. GeckoDriver v0.18.0: Firefox 53.0 (and greater)
  3. GeckoDriver v0.16.0: Selenium 3.4 (and greater)

Mozilla Firefox Versions :

Ideally, each Selenium release should support each version of Mozilla Firefox releases (starting with Firefox 48.x) where the property "marionette" needs to be set to true (either by default or through configuration) as follows:

cap = DesiredCapabilities().FIREFOX
cap["marionette"] = True

If you are working with the legacy Firefox releases (till Firefox 47.x) GeckoDriver still works but you have to explicitly set the property "marionette" to false as follows:

cap = DesiredCapabilities().FIREFOX
cap["marionette"] = False
