==== DRM Related Logging Steps ==== | |||
For DRM content (Amazon Prime, Netflix) it can be helpful to generate EME related logging. Follow these steps:<br/> | |||
1) Open a command console and browse to your install location for Firefox.<br/> | |||
2) Enter 'set MOZ_DISABLE_GMP_SANDBOX=1' in the console<br/> | |||
3) Launch Firefox from the command console (firefox.exe (return))<br/> | |||
4) In the browser, open a tab and visit about:logging<br/> | |||
5) Enter 'GMP:5,EME:5' in the 'new log modules' text edit and click on 'Set Log Modules'<br/> | |||
6) Under Output choose 'Logging to a file' and choose a suitable temp path and then click 'Set Log File'.<br/> | |||
In the temp dir, you should get two logs (something like 'emelog.txt-child.23884.moz_log' and 'emelog.txt-main.23435.moz_log'). Post these to your Bugzilla report. | |||
