Sprawdziłem i okazuje się, że to zużycie RAMu przez przeglądarke Firefox jest jak najbardziej w normie.
U mnie sama przeglądarka (bez otworzonych kart) zużywa 400 MB pamięci RAM.
Moja specyfikacja sprzętowa:
A to zużycie RAMu przez uruchomione programy:
Pamięci RAM mam 8 GB, a zużycie to 5%, więc 0,05 * 8 = 0,4 GB pamięci RAM, czyli 400 MB.
A te procesy tworzą się po otwarciu jakiejś witryny internetowej i są potomnymi procesu GeckoMain (Gecko to silnik Firefoxa):
Na podstawie tego co widzę wszystko jest w normie.
