hi, not sure where to start this issue as its been building up over the last 1-2 months more and more. i had brushed it off for a bit but its become quite apparently an issue on Firefox and nothing else. the main thing is that when i click into different tabs, certain pages turn blank (for example, when i away from Youtube i got back and the page is just white) until i click again. but this also occurs on other pages in a way where anything not present is loaded but scrolling down its blank. this happens a lot with tumblr or twitter, and often times i need to completely refresh to fix it. it often lags too when this happens, the pages being slow to respond. i have had other pages where you need to click or scroll to load feeds (soundcloud for example) where they just wont load the content after i scroll and it remains blank. i thought it was specific sites and not the browser but its apparent its just firefox. chrome works fine and so does Edge. i have looked at solutions here related to issues with loading but none seem to fit the bill for my issue and arent relevant/dont seem to change things.
