The error is part of the Web Animations API:
https://www.w3.org/TR/web-animations-2/
Note the remark on that page:
Not Ready For Implementation
This spec is not yet ready for implementation. It exists in this repository to record the ideas and promote discussion.
The site should not be using this API, regardless if some browsers may have implemented
the working draft.

Reply from Yohan Boniface on the umap mailing list
Sorry to see issues in Palemoon.
We've made a few checks, and it seems too costly for us to maintain Palemoon compatibility in uMap.
We try to preserve as much as we can compatibility for "old" browsers (we are strict on not using features not in "baseline 2021" , which means implemented in major browsers before 2021).
See
https://developer.mozilla.org/en-US/doc ... patibility
But it seems Palemoon has other bugs (eg. we have one with z-index+var in CSS preventing the edit bar to show above the map), and it will take too much time to workaround those.
We've made some fix for viewing the map (will be in next release), but are unable to fix all the issues to be able to edit the map right now.
Sorry!
You can still use Firefox if you don't want to use Chrome-like browser (we do use Firefox ourselves).

Restricting editing to a smaller collection of browsers is absolutely fair, IMHO.
Being able to use it for viewing/lookups though is a lot more important and I'm happy to hear basic accessibility in that respect is being addressed in the next release!
Unfortunately "Baseline" being decided upon by a single vendor who bases their "baseline" on whether their engine has adopted Blink behaviour yet or not isn't a fair criterion, but I guess that is a discussion for another time.

I saw no buttons on the left, even with LibreWolf.
