Hi Gareth, I have solved it. The solution: *drumroll* Switch from Ubuntu to Bookworm.

Thanks Brad, Max, Greg, Jeffrey, Tomas and the unnamed Briton. I have used Bookworm earlier, but the apt policy bit and Max's reply drove me to return. Some confusion may still be in order though: Nikulin's suspicion that a copy of the file is used seems true: changing non-pinned icons in Ubuntu's panel worked without a reboot, but not Firefox. I tried looking into the GNOME source (grep-ing into that address) but in vain. The desktop-file-validate tool threw no error. Incidentally, the Ubuntu desktop file had a single hyphen in the sub-entry for private windows (Bookworm does not have sub-entries), but I've used both single and double hyphens earlier. But I am using double hyphens now, as Brad warned. I don't think *I* should raise a bug as Max suggested: unless a significant number of users is interested, I wouldn't want to, although not having your data out there is better IMHO. Perhaps some day I'll contribute the feature myself. Thanks again, Pranjal
