Okay tool I would say, but it would have been nice if the GUI was reworked a bit, and if it actually supported the `window.addEventListener(func)`. For me this never triggers, and I have to sometimes run the code at a point that it only affects part of the page because other elements have not fully charged yet.
The extension works great & as expected but it should have the feature @Yassine Safraoui asked for ( list of snippets & enabling them easily ). Also, one important thing is that the URL is remembered along with it's query data. This should either be disabled or optional. Sometimes query data changes for the same site.
Works like charm, but there is a feature I miss tough, since you can remember the code running on a website, it would be preferred to make like a list of snippets the user can run, or disable on a website real quickly.
