Bugzilla

## In a few words

Reported by temp-453632 on Element[1]. At first, I didn't see the link between `gimp-help-en` and `firefox`. After some investigation, we realized we need to add something like `Provides: www-browser` to `control.in`[2]. 

## More details

temp-453632 tested several cases. We confirmed this behavior only occurs when he install Firefox from our debian repository. temp-453632 is on Kubuntu 20.04. On that version, `gimp-help-en` depends on one of these packages[3]:

> gimp-helpbrowser
>    Package not available 
> or www-browser
>    virtual package provided by [hide 23 providing packages] chromium-browser, dillo, edbrowse, elinks, epiphany-browser, falkon, firefox, hv3, konqueror, links, links2, lynx, midori, netrik, netsurf, netsurf-fb, netsurf-gtk, surf, w3m, wslu, xemacs21-mule, xemacs21-mule-canna-wnn, xemacs21-nomule

Canonical puts this metadata in their Firefox package[4]:

```
Provides: gnome-www-browser, iceweasel, www-browser
```

I guess that explains the difference of the behavior that temp-453632 saw. :gabriel, what do you think?
