MDL-54589, where we got working Selenium 2.53.0 + FF 46.0.1 for 31_STABLE and up.
Selenium 2.53.1 was just released and it includes the needed changes to the selenium xpi to get FF 47.0.1 (also just released) working.
There was a problem with FF 47.0.0, where they broke Selenium access.
So, as far as this is the LAST version of Firefox considered compatible with selenium driver (Firefox 48 will require to switch to Marionette), this is issue is to:
- Check that 2.53.1 + FF 47.0.1 is a valid combination.
- Publish it in the list of working combinations.
