@przhnk Thankfully, for me it's lasting a few days. Might want to experiment with using fewer open tabs or closing particular webpages that you might normally have open to see if there is any pattern to the behavior. Could also try clearing cache/history to see if that has a longer lasting effect.
Beyond that you might do some searching for any tools to address memory leaks. I remember there was a bad memory leak in Windows a few years ago that would cause PUBG (and other games) to perform very poorly due to building cache memory that was never dumped. Someone came up with a workaround that set up a scheduled windows job to dump the cache manually every X amount of time.
Not saying this is the problem but it might be worth exploring if something similar is happening. For reference this is the video that I used years ago and it actually worked great (Windows has since fixed that issue as far as I know): https://www.youtube.com/watch?v=WnKDPLjbg_I
I used that method years ago and it was fine but you should always do your due diligence with downloading anything if you decide to try something like that.
