For me, Firefox 115.0.2 (64-bit) on Windows 10 64-bit is tab-crashing on this site. Basically, whenever any action tries to load content in the top right pane/treeview.
MS Edge is not affected, so no doubt it's a bug in Firefox.
Firefox has good automatic error reporting functions, so I imagine they already have multiple bug reports.
This post created using Edge (under duress ;))
