My questions are:
- Does the DuckDuckGo Firefox extension “Privacy Essentials” add a local css file to every visited site?
- Can others reproduce this?
- Is this harmfull or not?
Background:
I have a simple static one page site with just one html and css file. It’s completely tracker free. Debugging it a bit with developer mode (F12) on I discovered a second css file. This file isnt on my webserver but added local. To pinpoint what caused this I removed every add-on / extension in my browser one by one, reloading and checking my website every time. Took me a while because didnt expect this one causing it.
To reproduce:
- Install the extension from the link.
- Open a random site
- Check in developer mode the tab Style editor.
- Scroll and look for a file named %3Ais(%5Bid*%3D’google_ads_iframe’%5D%.css or something like that.
- Remove the extension and refresh.
- Check if the file disappears.
Content of the css file: :is([id*=‘google_ads_iframe’], [id*=‘taboola-’], .taboolaHeight, .taboola-placeholder, #credential_picker_container, #credentials-picker-container, #credential_picker_iframe, [id*=‘google-one-tap-iframe’], #google-one-tap-popup-container, .google-one-tap-modal-div, #amp_floatingAdDiv, #ez-content-blocker-container) { display:none!important; min-height:0!important; height:0!important; }

I hate W3Schools and Geeksforgeeks, I have them blocked on my search lol
MDN all the way
What is wrong with them? I have found the useful and there examples help me to learn more about context. I am not saying anything about MDN, it may just be superior, but I’ve rarely referenced it.
W3Schools used to be terrible, but it’s gotten better. MDN is still great, but it’s very much a pure technical reference, not great learning material.
Well, when I was learning I didn’t see any issue in using it. I also just learned they have a learning area
