It looks like an update of presumably Firefox Nightly breaks browser initialization on both bots with:

JavaScript error: , line 0: SyntaxError: Failed to parse import map: Invalid JSON format. JSON.parse: expected ',' or '}' after property value in object at line 38 column 11 of the JSON data
JavaScript error: http://127.0.0.1:40915/test/unit/jasmine-boot.js, line 43: TypeError: The specifier “pdfjs/display/worker_options.js” was a bare specifier, but was not remapped to anything. Relative module specifiers must start with “./”, “../” or “/”

I also have this locally too now, so it's not related to this patch or e.g. the PR with dependency updates.

r=me, with a rebase and passing Windows tests (since they failed). Thank you for the fix!
