I tried Pale Moon because u/Gemmaugr keeps recommending it.

Pale Moon is a browser based on their own optimized layout and rendering engine, Goanna. Before I start using it, I have to install it from their webpage. And here is their webpage:

This page looks like it's written by a guy in 2010 who just learnt what HTML is. It really could look better. But let's not judge a book by its cover. You can see the browser is receiving updates in the top news.

And then I installed it. Here is the UI:

Nostalgic, right? And the homepage is full of stuff I won't use. You can change the new tab page to a blank page if you don't like this.

You can customize the UI too.

It feels like Firefox, where you can drag things to the toolbar. You can also install themes from Pale Moon's website, however most themes are as nostalgic as the default one.

You can also install extensions from their website too. This is an adblocker from the official Pale Moon team:

However, Adblock Latitude failed to block YouTube ads and Reddit ads by default:

I think you have to add the filter lists yourself to make this usable.

There's uBlock Origin legacy, but the extension site takes you to this GitHub page:

In conclusion, it's probably ok to use it to just open websites, although the UI may look unappealing. However I see no reason to use it instead of Firefox rebuilds like Librewolf or Floorp, and the settings are a little user-unfriendly for simple end users like me. If you worry that Firefox will die in the near future, and you personally hate Chromium, maybe Pale Moon is for you. If I said something wrong please correct me.

For comparison, my Librewolf scores 505.
