Launching Firefox on Windows fails on CI

[jackfranklin]

@whimboo @mjzffr we're seeing this test fail on Windows CI builds when launching FireFox: #5954

We initially disabled the test because our Windows CI was so flakey it was impossible to know if it was a genuine bug or not but it now does appear to be as our CI on Windows has been very stable until this test got re-enabled.

That PR above defers the test for another month, in the meantime would you mind having a look if you get a chance?

Thanks!

Update: there's actually two tests causing Windows issues : https://github.com/puppeteer/puppeteer/pull/5954/files

Would you mind looking at both? Please shout if I can help :)

@jackfranklin The one in headful.spec.js is under describeChromeOnly so you should probably take a look. :)

@jackfranklin isn't that just a dupe of issue #5673?
