Yup dumdum, I've tried to explain that Zen also has this expanding 'thing', but unlike with Firefox it can be placed opposite side of the vertical tabs. If you for instance press Ctrl+B and you get the expanding thing (sidebar) with bookmarks. Just like in Firefox it expands and reduces webpage space. The overlay is something else, called the web panel. Something Zen introduced which is additional to the sidebar and not a replacement of it. I've even taken the time to show it in a screenshot, but apparently that makes me a smartass.

Can also try Here Wego. It looks a bit more polished and I have better success using its search function. Only downside: spoken navigation instructions are TTS only and sound quality is bad over Android auto...but I have them disabled anyway.

Yes, but a bad example of one very quickly heading towards autocracy. Some characteristics like screwing up your own economy and blaming 'the foreigners' rings a distant bell.

The Tesseract web app does that. It stacks posts in the feed that have the same url or title.

A popup is overlay / in front of your viewport or UI, the sidebar is not in front of it. If what you see is (like a) popup, you're talking about the web panel, which a different concept Zen added. Indeed in Firefox the vertical tabs are part of the sidebar and thus they can't be move independently. In Zen, the vertical tabs are NOT part of the sidebar, and thus you can move the sidebar to the right while the tabs remain on the left.

It's configurable from the sidebar dropdown menu, e.g. when opening your bookmarks (Ctrl+B):

But you can also use this about:config setting:

Again you keep calling it a popup, but it really isn't. It does not pop up or overlay the browser viewport, it sits on the right and pushes the viewport left reducing its width.

There's the Danish company Lyngdorf, who make the CD-2. It costs a whopping €2999,- though. NAD is Canadian and makes CD players around the €400 mark. If you consider Canada an honorary EU member that's an option ;)

Aren't there several companies that donate to both running candidates, just in a 'betting on both horses' kind of way? Just making sure you're in good graces with whomever becomes president.

Perhaps https://www.cheapasssunglasses.com/ ? While the shop is European (Dutch), I expect the glasses are made in China.

I've donated in November after I switched back to Firefox as my main browser. I read about the search deal dependency and wanted to contribute to what Mozilla called "reclaim the internet". Feel something akin to 'buyer's remorse' when I now read how little goes to development of Firefox/Gecko (the only multi-platform alternative engine for rendering the internet) and how much goes into CEO salaries.

No, there are 'workspaces' -accessed via the buttons on the bottom of the vertical tab bar-with their own tabs, but you can't group tabs within one workspace (yet). And yes I can open the sidebar -which is not a popup- on the other side. The thing that's popping up on the left next to the tabs and overlays the site is what Zen calls the web panel.

That's Denmark (Danish), this article is about The Netherlands (Dutch).
