Is anybody aware of changes to
toString introduced in the recent release of Firefox version 74?
We are using a little self-hosted AddOn that worked fine up to version 73.x, but stopped working with the new version 74. When checking the AddOn via
about:debugging, I ran into “something.toString is not a function” errors.
I quickly got rid of
toString (sometimes by using
JSON.stringify instead, but mostly I just had to replace
console.log("var = " + var) with
console.log("var = ", var).
Nothing else was changed and the new version runs fine, so apparently, toString was really at fault.
Am I missing something deep here?
