please don't harrass or insult that website, but I recently browsed that website because I wanted to get a wallpaper, but then I realized the top bar was saying "Xenia suggests you get Firefox", wait what?? She wouldn't suggest that first of all, second, this means that the website knows if you are using Google or Firefox, so that can be a harmful addition. I will talk to the owner maybe, that is bad because all browsers can be good!! And that website is really pretty but I dislike that top bar.
Except that they've already displayed that they won't. Recently, Firefox users were targeted with an artificial delay on YouTube. When caught, they claimed it was about ad blockers... Except it didn't affect chrome users with adblock and affected Firefox users without adblock.
And this has happened multiple times over the years, where little headaches and inconveniences would crop up on Google services, all of which could be fixed by changing your user agent so the site thinks you're running chrome.
I though the delay thing turned out to not be true. Or did I misread something?
They admitted they were slowing users with ad blockers, but many Firefox users reported experiencing the slowdown regardless of whether they used an ad blocker.
The article I linked, however, says that they couldn't get the delay to happen at all, so it's entirely possible it was just so poorly implemented that it was affecting people almost at random.
