@yaguznal i dunno if this will help.. Go to opera://flags/ Enable this flag called - (Memory coordinator) it suppost to give the browser control of manage 'n memory instead of the operating system.. then later on perhaps this one.. try this Flag called - (Strict site isolation) *uses more ram probaly.. it is meant to make browser more stable and secure.. By separate 'n - every tab - plug 'n - extension - into its own process.. *may use more ram..
