Sad to see a post by Mozilla only referencing Mac and Windows shortcuts to start the debugger. Most of the web developers I know are using Linux for web development, including javascript (some are using MacOS, none Windows).

On Ubuntu, the debugger is started by using S (like Windows actually).

Are there any shortcuts on Linux which are different from those on Windows by default?

I don't know any Web developers using Linux on their desktops, as company policy requires Windows desktops.

Linux is only used for Java based backends, when deploying into production.

With .NET deployments being done on IIS, even with .NET Core.

Some of the designers are using Photoshop on macOS.

Anecdote data.

I tried to use the Firefox debugger recently, but I could find where you set "event listener breakpoints" (e.g. a breakpoint that stops whenever a click handler runs, regardless of which element was clicked). Some documents seemed to suggest that Firefox has this feature but I tried multiple versions of Firefox (including fiddling with the "new debugger frontend" flag in about:config) but I just couldn't find it anywhere?

If we’re doing anecdata, then every web developer I know is on Macs, apart from those at the company I’m consulting for at the moment who have mostly standardised on Windows.

Set about:config?filter=devtools.debugger.new-debugger-frontend to false, then reopen the debugger and expand the right pane, the Events tab should be there: https://i.imgur.com/GLGrc7y.png.

I agree. As a Linux user I always just assume they are the same as Windows.

And for those curious, here's the issue for bringing the feature back in the new debugger: https://github.com/devtools-html/debugger.html/issues/4750

That was my point, each one has a different OS scenario depending where in the world we live on, the policies at workplace and customer sites.
