Copyright Button Throwing JS Error on Firefox

Recently I noticed some H5P exercises not loading on Firefox 50.1.0 (Mac). The browser times out. The console output is:

Error: Script terminated by timeout at:
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]  h5p.js:1056:1


The console indicates the error occurs at: h5p.js:1056:1 

At which line the debugger shows an empty else statement:

else {


I found that unchecking the 'Copyright button' option in the exercise editor solves the issue. 

The problem doesn't occur on Chrome.
