Hello to everybody, My question: Opening local .mdb files (MS Access database) does no longer work in Firefox 120, but was ok in previous releases. The only choice is to save the file rather than onening it with MS access. Under Firefox settings/applications the file type .mdb does not appear. If I answer the question "What should Firefox do with other files?" with "Ask whether to open or save files" it has no effect at all. I expect to find an entry for .mdb files where to choose "always ask" as was the case earlier. Please help!

Regards Volker Zipp

Problem solved with about:config: dom.workers.importScripts.enforceStrictMimeType false -> true, thereafter appears in about:preferences "Microsoft Access Database".

Good job. Mark it as resolved to remove it from our list.
