It isn't especially mobile-friendly, but the (fake) scrollbar works for me on Android.

Slop warning: it is 100% generated. It is a joke after all...

It is a joke! The data is randomly generated. Any similarity to reality is coincidental.

That said, the numbers are just numbers, and every possible one is in the list, so there is definitely overlap with real cards.

RSS.style is my site. I'm currently testing a JavaScript-based workaround that should look just like the current XSLT version. It will not require the XSLT polyfill (which sort-of works, but seems fragile).

One bonus is that it will be easier to customize for people that know JavaScript but don't know XSLT (which is a lot of people, including me).

You'll still need to add a line to the feed source code.

There wasn't free hosting in 2003 when I first made it. I have thought about converting it to static, but it would be a complete rewrite, and there is always some other new shiny thing to play with instead.

The newer things I'm doing (like UnicodeSearch.org) are static, though I don't like forcing everyone to have JavaScript enabled.

I get where you are coming from, and have put some thought into it.

I built the site over 20 years ago, and while it was fun to make, I wouldn't have maintained it this long if is was costing me every month.

I've tried to minimize the intrusiveness: I disabled the pop-up and interstitial ads and I don't serve anything different to people with ad-blockers. And I've stuck with Google Adwords, despite requests from all sorts of questionable alternatives.

I'm not sure about the future: bots are causing all sorts of trouble, and the ad revenue is trending down and is now less than break even.

And these aren't niche/advanced features? I'm using Firefox now, and did not know about them. If I'm using them, it is only accidentally or because they are the defaults.

But I'm agreeing with you! These features are important to you, an advanced user. The more advanced users for Firefox, the better.

I agree with you. But a typical consumer will already be using Chrome, and has no reason to use Firefox.

If one of these advanced/niche technologies takes off, suddenly they will have a reason to use Firefox.

I don't disagree with you, but given (A) how will Firefox ever compete?

One possible way is doing things that Google and Chrome don't (can't).

Catering to niche audiences (and winning those niches) gives people a reason to use it. Maybe one of the niches takes off. Catering to advanced users not necessarily a bad way to compete.

Being a feature-for-feature copy of Chrome is not a winning strategy (IMHO).

Which is why Firefox is steadily losing market share.

If Mozilla wanted Firefox to succeed, they would stop playing "copy Chrome" and support all sorts of things that the community wants, like JpegXL, XSLT, RSS/Atom, Gemini (protocol, not AI), ActivityPub, etc.

Not to mention a built-in ad-blocker...

I don't want the feed to look amazing. I just don't want to present a wall of XML text to non-technical users who don't know what an RSS feed is!
