Recently I defined a new profile. When in that profile, and when clicking for example a link to a pdf file, I am not being asked whether to open or save it, although in Preferences/File Handling both "Offer to save the file" and "Ask whether to open or save the file" are checked. The save dialog appears, without any questions.
When I reactivate my previous profile then everything is as expected again. The content of mimeTypes.rdf is very different - manually copying that file from one profile to another would probably help (but I did not try that). But still, I do not understand why am I not asked what to do, when the option is checked. And why was/is everything as expected in my usual profile?
