I am talking about the feature in Chrome, opening the 3-dot-menu at the top right of the dev tools > More tools > Request blocking
This feature is amazing, and it remembers the domains/urls to block, however every time you close the dev tools it un-checks the box "Enable request blocking".
I want to block some stuff all the time, regardless of whether the dev tools are open... Is there a way to keep this from un-checking itself? It is possible to keep it open in the background, but it doesn't even transfer to a new tab if the current tab opens a new one. Perhaps there are some new flags that can be set in newer versions (now we are on Chrome 79, and this question was originally asked with Chrome 63).

Unfortunately not the solution. However my workaround for that is to have the dev-tools as a separated window either minimised or just in the background if i don't need or want them.
