How to check the history of private browser mozilla or chrome.
Chrome: Ctrl+H
Firefox: Ctrl+Shift+V
firefox- ctrl+shift+H
crome- ctrl+H
FF is ctrl+shift+V for me, I thought that would be the same for everyone?
And chrome I already posted, so no need to repeat 
Simple…! For Chrome history - press key CTRL + H and for deleting Press CTRL + Shift + DEL to open the clear browsing data window
For Mozilla history - Click history on toolbar and go ‘show history’ or CTRL + H or CTRL + SHIFT + H And for deleting press CTRL + Shift + DEL to open the clear All history window.
