(Update: fix in release 3.3.3!)

Thanks for the feedback kitsunesan!
I've gotten scattered feedback about this as well. If you're able, can you please post a few more details on https://github.com/wingman-jr-addon/wingman_jr/issues/185? If not, can you maybe add a few more details here about what you see? I'm assuming Firefox is giving the "Keep tabs hidden?"-style prompt but let me know if there is more going on here.

(Update: for anyone struggling with the hidden tab, check out the Background.js WebGL backend option in the addon!)
