Stop reordering my tabs!

[Osplo]

Firefox 137 messes the order of my tabs. It puts the most recently used to the right... I DO NOT NEED OR WANT THIS. Please let me switch this behavior off!

Thanks

This is happening to me, too, and I also cannot find a setting to turn it off. Even worse, it doesn't seem to happen every time, and I can't figure out why. Please allow us to turn this off! It has messed with my entire flow.

It's happening to me too. I hate it. Can't figure out why it doesn't happen every time. Please let us turn it off!!

This is a huge backwards step!  I want some way to turn this off.  It's driving me crazy.

 I have just created this account for the sole purpose of reporting this issue.

This AB experiment drives me crazy and messes up the workflow i'm adjusted to. Please make this stop!!!!!
