Seem to have new issue adding Dials to a Dynamic group FF129

[mikwei]

So when selecting item to add a new dial, no way to perform with a Dynamic Dial, works on other group types.
Even when on group do not get [+] on any dials to add manually.

Seems issue with FF 129.0.1 (64-bit) on Linux, have not tried under windows. Does work in Brave.

Thanks a lot for reporting this!
If I'm seeing it right, it's caused by the new option "Hide last "+" dial in dynamic layout". If you disable it, it should be visible again (it's in the Options page / Dials / Hide last "+" dial in dynamic layout).
It will be fixed in the upcoming 25.9 version.
