I met the same issue with https://stackoverflow.com/questions/27514404/web-worker-blocked-by-main-thread-in-chrome . It was asked 10 years ago and I learnt that it was fixed in chrome via https://issues.chromium.org/issues/40398809 . Is it a bug for firefox? Is there any way to work around? Thanks.

Isisombululo esikhethiwe

Yes, we have an open bug for it: https://bugzilla.mozilla.org/show_bug.cgi?id=1330826

I guess the workaround is to use the PFetch protocol.
