Working combinations of OS+Browser+selenium

As OS, Browsers and Selenium keeps updating, some combination might fail on different Moodle releases.

Following combinations have been tested at the time of release of Moodle version and will be supported for that combination.

Moodle 3.9 and up

OS	Browser	Selenium Server	Browser Driver	Notes
Linux - Debian Stretch/Buster	Firefox 83.0	3.141.59	Geckodriver 0.30.0
Linux - Debian Stretch/Buster	Chrome 86	3.141.59	86.0.4240.22	Any other valid combination should work ok, normally. (Here there is a good list of them, as reference) Chrome >=76 can be used since Moodle 20190909 builds. Chrome >=93 can be used since Moodle 20210916 builds and requires to exclude the @skip_chrome_zerosize MDL-71108 tags till the browser issue is fixed.
MacOS X	Firefox 83.0	3.141.59	Geckodriver 0.30.0
MacOS X	Chrome 86	3.141.59	86.0.4240.22	Any other valid combination should work ok, normally. (Here there is a good list of them, as reference) Chrome >=76 can be used since Moodle 20190909 builds. Chrome >=93 can be used since Moodle 20210916 builds and requires to exclude the @skip_chrome_zerosize MDL-71108 tags till the browser issue is fixed.

Chrome >=93 can be used since Moodle 20210916 builds and requires to exclude the @skip_chrome_zerosize MDL-71108 tags till the browser issue is fixed.

note

Many of the combinations below, for older versions of Moodle 3.5 and up, should continue working acceptably well for Moodle 3.9 and up. Just the those listed above are actively being used now (CI infrastructure, developers...), hence, verified to be running ok. Feel free to add more relevant working combinations!
