Which Firefox browser versions supported for given Geckodriver version?

问题

I regularly update Firefox and Chrome browser, current version 54.0.1 32 bit So which version of Geckodriver to be used. I tried with both version Geckodriver-v0.18.0 and geckodriver-v0.16.1

For future reference where can I find the list the supported firefox browsers with respective geckodriver versions

Note: No any code changes in launch browser

Previous the code was working with geckodriver-v0.16.1 for older firefox versions Now getting exception after updating firefox 54.0.1 and Geckodriver-v0.18.0 :

org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms.

This Question have been surfacing out quite often for sometime now since we migrated from the legacy Firefox releases to Marionette based Mozilla Firefox releases (beginning with Firefox 48). It is not clear what exactly you mean by the code was working with geckodriver-v0.16.1 for older firefox versions.

In general, each GeckoDriver release supports each version of Mozilla Firefox releases (beginning with Firefox 48) where the property marionette needs to be set to true (either by default or through configuration)

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

Now, the only dependency which exists, is between GeckoDriver and Selenium releases. The GeckoDriver release notes clearly mentions all the major/minor New Feature Addition, Enhancements,Bug Fixes and Download Location separately in this link.

The last announced dependency was:

Note that geckodriver v0.16.0 is only compatible with Selenium 3.4 and greater.

The canonical source of this information is published by Mozilla in the official geckodriver documentation. The docs are updated with each new geckodriver release.

The main documentation link is located here:

• https://firefox-source-docs.mozilla.org/testing/geckodriver/geckodriver/index.html

... and specifically, see the "Supported platforms" page here:

• https://firefox-source-docs.mozilla.org/testing/geckodriver/geckodriver/Support.html

It contains a mapping between geckodriver releases, supported versions of Firefox, and required Selenium versions.
