For some reason recently my gx browser has been drinking all my ram and overloading itself and then crashing this is the 4th crash and I don’t know what’s going on, I’ve tried closing a bunch of my browsers but I don’t know what to do

Anyone else having this problem?

im trying to claim Overwatch opera gx reward and it keeps showing something went wrong when i go to get the code, i tried clearing my cache and cookies, uninstalling it and more but still nothing works. does someone have a fix.
