Ive notcied in the last few weeks that sometimes whn i open mozilla and try watch youtube the webpage loads but no vidoes will work. I have the same issue with my Trading212 website, it loads up but will not log me in or anything. I have never had any issues with mozilla before but now everytime i switch my pc off anf try to use Mozilla it just does not work. To get it to work i have to start the uninstaller for mozilla and go through the reload/refresh process which does work in allowing me to watch youtube vidoes and sign into my trading account but it seems super unesscary that i hav e to do this every time i want to go online, I really like Mozilla but if this continues I unfortunately will have to find another browser.
