• (2022-04-24) D_00: 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.

• (2020-11-04) Samagra Singh Tomar - Incendia: 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.
• (2020-02-04) Ivan Pruchai: It works, but after page reloaded you need to paste code and save again.
• (2019-08-02) Yassine Safraoui: 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.

• (2018-11-17) Would have been nice if 1) It worked (tried the same code as in the example image here, in the addon and in the dev console which made it clear that it's this addon that does absolutely nothing at all) and 2) It worked by adding multiple scripts that the user can click to execute whenever.

• (2019-08-02, v:1.2) Yassine Safraoui: Suggestion
  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, for instance, youtube is one of the most websites that fills up my ram, especially when watching videos, the problem is that the suggestions part of the page(which I rarely consult) is taking a great space of ram, so I can run some code to remove it, and another problem I face is when I open a video in the fullscreen mode while I'm pausing the video I can't take a screenshot becasue there is a div dimming the screen so I can make a some code to solve that, so the snippets gonna definitively come handy, and why not make a shortcut to enable / disable them, I hope consider these suggestions, because I miss them so much! Best regards.
