Can "Error loading Script" js errors be ignored?

I have a script to handle window.onerrors and push it to my server. I see some "Error Loading Script" errors that happen only in Firefox.

I searched around and people were ignoring "Error loading Script" errors. For example

1. Cryptic "Script Error." reported in Javascript in Chrome and Firefox
2. Firefox: "Error loading script"

Can these errors be safely ignored like the above? Or should I ignore only in Firefox?
