Add console logging back to browser extension

[rc10house]

This commit #6950ee9 removed printing captured logs to the console in the web extension (specifically line 1167 in content.js). @poorejc found this while attempting to use the 2.4.0 web extension. @Jyyjy not sure if you removed this on purpose or not, but it seems useful to add back in.

I'm guessing I removed it when cleaning up debugging prints. If you found it useful, please add it back in. In a perfect world, I think the base package should have a logging level param that can be set in the web extension.
