Result is cached even when using Ctrl+F5 in Firefox

[JayEn84]

Today, I found a bug in an XML sitemap after displaying the XML file with this wonderful plugin by calling domain.com/sitemap.xml . I fixed the bug, so the XML file on domain.com/sitemap.xml has changed.
However, the plugin still displays the old version of the file, even when pressing Ctrl+F5. It seems it is cached somewhere.

Funny effect: I disable the plugin, the new version of the file appears, which is then of course displayed by the standard Firefox XML output view. When I reactivate the plugin, the cached version is displayed again. :-o

This bug is still present, I was going crazy because my app was not showing my changes then I realized the results are cached not by FF but this plugin.
