Firefox error: "Uncaught DOMException: CSSStyleSheet.cssRules getter: Not allowed to access cross-origin stylesheet"
See original GitHub issueRecreating #278 but with a call stack:
SecurityError: CSSStyleSheet.cssRules getter: Not allowed to access cross-origin stylesheet
at d/e.handlePrint/M.onload @ https://www.codecademy.com/webpack/252.4033dce2c049256b0fb3.chunk.js:1:4303
252.4033dce2c049256b0fb3.chunk.js.txt
The specific line that’s throwing the error is https://github.com/gregnb/react-to-print/blob/c224cf7f03c7fc44478cafd60fef2a822d97adca/src/index.tsx#L376
Root cause: sheet.cssRules is getting blocked by Firefox: https://discourse.mozilla.org/t/webextensions-porting-access-to-cross-origin-document-stylesheets-cssrules/18359 / https://discourse.mozilla.org/t/accessing-some-fonts-css-style-sheet-via-stylesheet-throws-securityerror/38717.
I don’t know how to work around this 😄 … maybe log a warning and continue without the styles?

The fix for this has been published in v2.14.1, please let me know if you run into any other issues. Thanks so much for the debugging help!
Hi @JoshuaKGoldberg thanks so much for the report and big thanks for the links, that explains a lot. I’ve made a comment on https://bugzilla.mozilla.org/show_bug.cgi?id=1393022 so hopefully we can get an answer from the Firefox team soon, but I agree for now it would be nice if
react-to-printcould do its best to gracefully handle the error. I’ll take a look at pushing a fix for that this weekend!
