so i think i found a way around it. extensions wont work because my admin blocked all other extensions on the Chromebook. so i was messing around with the chrome://chrome-urls type links that are only available on the Chromebook. I then came across the chrome://supervised-user-internals Chromebook link and i found out if you type in a link in there it somehow unblocks Content keeper but only at my home WI-FI network. the same trick doesent seem to work at my school network though a proxy network could get it to work. I hope this helps. edit: whelp school blocked task manager so i cant get around securly anymore rip. edit 2: contentkeeper seems to be generally blocked at my home network now but securly is still able to block certain sites at home and at school. Edit 3: I feel like contentkeeper is no longer a problem for me, but now securly is getting in the way. It is forced by administrator, i can go into task manager but cant end any tasks because my school found out about the task manager trick. cant go in developer mode, I even tried to factory reset my chromebook and get into developer tools, but even that is blocked. ive recently been trying ways to get around it but none worked. I might find a way soon but for now still have these sites blocked. Edit 4: also apparently real-time html editors dont work either which sucks.
