[tbb-dev] Attn: Beginning 91esr transition, expect Nightly breakage

[Matthew Finkel]

Hello everyone,

Tor Browser's transition from Firefox 78esr to Firefox 91esr is in
progress. Please expect Nightly breakage (and sorry for any
inconvenience this causes).

Please open issues on Gitlab [0] when you experience new
bugs and regressions.

Thanks,
Matthew
