Is it possible to write a Chrome/Firefox plug-in that can automatically open the dev tools for every open tab and execute code in the console? I have already done this with Selenium, but I would like to have it as a plug-in.
Unfortunately, I haven't found a chrome api yet that allows you to automatically insert and execute code in devtools.
I would be very grateful to anyone who could help me get a step closer.
PS:Since I don't add the plugin to the store, developer API's or other unconventional alternatives can also be used.
