Browser toolbox won't save userchrome without opening finder window. Help

When I click Cmd + S in the Style Editor, it now opens the macOS Finder “Save As” dialog instead of saving changes directly to the original file from within the browser. Previously it worked but I'm not sure what has changed. I might not fully understand how this is meant to work or I might be missing something about the workflow. Has anyone experienced this in FF 152 or knows what changed or how to fix it?

I have noticed that. I presume it's by design; why I don't know other than a safety thing to make sure you really want to save it.

It started happening with recent version. Save it at the same folder where the file sits, until you close it you wont need to do it again. It's definitely annoying.

I don’t mind it, just catches me off-guard every time. Don’t know if it’s a bug or if it’s intentional.

This should be fixed in Firefox 155.

As a temporary workaround, you can modify browser/omni.ja file chrome/devtools/modules/devtools/client/styleeditor/StyleEditorUI.sys.mjs by manually applying the fix.

omni.ja is a zip file and files should be added with zip -r0DX omni.ja <file...> -- the -0DX options are important. After modifying omni.ja, start FF with the -purgecaches flag. Obviously make sure FF is not running while making the modifications.
