As always, the dose makes the poison.
A common scenario is people picking the wrong species and then not just eating a small bite, but cooking an entire meal and eating that.

A small bite may not kill you, but just one mushroom (50g) can be enough to do it.

There are some toxic mfs out there and they can be mistaken for edible lookalikes by inexperienced foragers.

I’d say generally speaking it’s more likely that issues stem from extensions than from Firefox itself, so maybe try looking into that.

Btw tab reordering is only missing for private tabs on the latest ff on Android.
Unfortunately there is still no acceleration when reordering so the ux is not great when you have many tabs.

out of memory for the rest of this message (which included a full proof of Fermat’s last theorem)
