Created attachment 8533145 [details] loop_disabled_error.png User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:35.0) Gecko/20100101 Firefox/35.0 Build ID: 20141201162954 Steps to reproduce: Go to about:config using Firefox 34-37 on any OS (Windows, Linux, MacOSX). Search for 'loop.enabled' and set it to 'false'. Restart Firefox. Actual results: Loop functionality and loop button got removed like they should, bug the browser console now shows the error: Fx35: "[CustomizableUI]" "Custom widget with id loop-button-throttled does not return a valid node". Fx37: "[CustomizableUI]" "Custom widget with id loop-button does not return a valid node" Expected results: Checks for "loop-button-throttled" item/node should not be made once loop functionality gets disabled.
Apart from an error in console, is there any user-facing impact?
The error message in console is the only issue. No 'visible' problems besides that.
there's a do not disturb option - not a user exposed preference. going forward we'll be fixing anything

Arthur, please can you explain why you have re-opened this? It is something we've explicitly decided to wontfix, especially given the fact its an error in the console that doesn't affect users (admittedly comment 4 is a bit vague, comments 1 to 3 are more relevant here). However, I think you'll also find that it is fixed in 45 & later because we changed how our startup process is working.
I can confirm that. Even if it was marked as WONTFIX, it got fixed in Fx45+ because of all loop related changes.
Mark and Aris, I think you're right. Sorry for the noise.
