version compatibility of WebDriver with others

[Aditya Aggarwal]

Is there a way to know, as to what versions of following are compatible to each other :

1) WebDriver

2) geckoDriver

3) Firefox

I go with dates. I look at the dates for when a browser was released then I look for versions of WebDriver which was released just after Firefox.

• Go to https://wiki.mozilla.org/Releases
• Go to the release notes for Firefox
• Right now I see 56.0.2 was released October 26, 2017
• Go to https://github.com/mozilla/geckodriver/releases
• Right now I see 0.19.1 was released October 31, 2017
• Go to http://selenium-release.storage.googleapis.com/index.html
• Right now I see 3.7 was released November 2, 2017

If you want to test an older version of Firefox you have to find when it was released. For example, 56.0 would have release notes at https://www.mozilla.org/en-US/firefox/56.0/releasenotes/ (note 56.0 and not 56.0.0 in the URL). Or 55.0.3 would be at https://www.mozilla.org/en-US/firefox/55.0.3/releasenotes/. Once I know the release date for Firefox then I'd look for versions of geckodriver and WebDriver released just after Firefox.
