On Pardus 19.5, I checked in Firefox/Thunderbird preferences that they are default and in “favorite apps” also.
I use Thunderbird for read RSS flux.
The links (mail and RSS) I click in Thunderbird opened in Firefox.
But at some point, don’t opened in Firefox.
In addition Firefox changes status to “is no longer my default browser”.
I have already tried to delete Evolution but without result.
