According to your user agent in the first line you're actually on Firefox 91. Do you need to upgrade?

That is the user agent I set, but in About Firefox it says 94.0.1.

Thanks for the report. The kernel panic is a macOS bug that is likely to be fixed in a newer version macOS 11. The version you have (identified via 20B29) is a very early version of macOS 11. Please update your macOS version. At this time, the latest release is 11.6.1.

The bug is closed because it is not reproducible on newer versions of macOS.
