So I have to pretend I’m someone else to get to do what I want to do, for example, upload images to a journal entry on the BookCrossing site.
- In the Iceweasel browser Location Bar type:
to display the Preference Name, Status, Type, and Value.
- Use the Filter text box near the top of the window to locate general.useragent.extra.firefox.
- Double click general.useragent.extra.firefox to display a dialog window to allow you to change the value.
- I changed the value from “Iceweasel/188.8.131.52” to “Firefox/184.108.40.206” without any investigation of versions and just because this was what I read on the debian user mailing list.
Note: Also on the debian user mailing list, KS cautioned that “While this works, the user will always have the value as user-set and will not change with an upgrade.”
