Ctrl-S is now Browser-Save instead of Workflow-Save
When you hit Ctrl-S in a Workflow in ComfyUI, then this used to work as "save workflow". This is now apparently intercepted by the Browser (Firefox 153.0.4 on Linux Mint 22.3 in my case), so I get a browser save-dialog to save the page as .hml From the main Menu, you can still select "File" and then "Save", which works correctly. And from the Workflow Actions menu, the Save there also still works. But Ctrl-S no longer behaves as before (i.e. Save Workflow). (other keyboard shortcuts like Ctrl-O, Ctrl-A, ... all still work correctly)
My ComfyUI setup:
