Since kvstore is an RKV wrapper, and RKV is not supposed to be enabled in release when using an LMDB backend, about:support and MediaCapabilities performance benchmarks should use kvstore with safe mode enabled instead.

This bug is a merge of bug 1596012 and bug 1596051, since a single fix applies to both.

Depends on D54279

Depends on D54281

There are some r+ patches which didn't land and no activity in this bug for 2 weeks.
:vporof, could you have a look please?
For more information, please visit auto_nag documentation.

Landing soon.
Update: this was deprioritized after the reorg, shelved.

I am now picking back up the work here.

Any update on this? :)

On it and hope to land asap before the soft freeze. Thanks for the ping!

Automatic migration between backends now landed in RKV and pushed to crates.io.
