Where to find content pages in Control panel?

[Ittermat]

Ever since the other day for some reason- sometimes when I go to some added content pages on my site- and go to edit them it completely freezes my browser and My plugin container on firefox crashes- it seems to do this no matter what browser Im using or what system im using- so its not a computer problem- as it also crashed on my tablet. But its a random page it seems to affect... Last time it was one of my snow mountain cemetary pages- I just deleted it since the page wasnt really needed and it solved the problem....now its on a page I DO need... so I was wondering if there was a way to get into the coding on these content pages in the control panel/Php my admin

I couldnt find them.

I wanna see if I can still at least have the option to edit them somehow...rather than having to delete them...

Not only this but deleting them then making the page again makes the problem reappear on the new copy...

I dunno...its weird. 0.o

EDIT: Found where I can edit them in PHP my admin- freezing problem still persists if I try to use the ACP for now this will work..
