And Opera is the only one who got tab switching with Ctrl+Tab right. That's the single most important feature which made me use Opera as my default browser.

(For dev tools, just press Ctrl+Shift+I instead of F12).

Interesting. One of my biggest issues with Opera is its seemingly random tab switching order. If I open ten tabs and want to go through them one by one, I first have to go through all my old tabs. There used to be an option to change this, but they removed it long ago :/

I like Vivaldi[1] for its keeping most of the options, such as the one you've mentioned.

opera:settings > type "cycle tabs in most recently used order" and uncheck (some text editors also use that by default, hate that)

Opera is switching tabs by "most recently used" order, just like Windows does for applications with Alt+Tab. That's exactly what I want, but if it confuses you, you can turn it off in the settings ("[x] Cycle tabs in most recently used order")

In Firefox, enabling `browser.ctrlTab.previews` makes the Ctrl+Tab behaviour much nicer. Not comparing, just noting.

This feature will be a first-class citizen in the preferences UI starting with Firefox 50: https://bugzilla.mozilla.org/show_bug.cgi?id=1116787

I concur. I could never use Chrome because I'd despise having to go through all my tabs just to get back to the last one I used. I tried a few plugins to get it to work but it never did. I can't remember what it was, but there were a few things about FF I could not get used to so I always went back to Opera.

How does it work differently from Chrome?

It switches tabs in most recently used order in Opera, similar to OS alt/cmd-tab behavior
