It works the same as 'PajacykXPI' extension, but for different website (siepomaga.pl).
It stores date when site was last time opened in preferences and if it wasn't today it opens site in new tab (look at about:config, siepomaga).
Website 'Siepomaga.pl' is in closed beta phase, but will be released soon.
