Has anyone found a way to make DTM Switch work with newer versions of Firefox? It doesn't seem to work with current versions.
I am on FF v45 and I haven't been able to get it to work. Alternatively, you can use the following in the console to do the same thing:
enable staging library in production
enable debug mode
There is a cheat sheet you can download on Jim Gordon's blog here: http://jimalytics.com/tag-management/dynamic-tag-manager-dtm-cheat-sheet/
Hope this helps,
