Apple Releases Safari Technology Preview 3 With Extensive Tweaks and Bug Fixes

All I want for Christmas is a desktop browser that doesn't autoplay videos.

Since Apple ignores basic usability with not showing icons in the tab bar, this safari browser can rott on in meaninglessness. What a pity.

As far as you're concerned, let it rot. For those of us who don't notice the icons, I see no great reason to put them there. Every time this "problem" is pointed out to me, I proceed to forget about it because it seems like a pretty small thing to get upset about.

Here's an HTML5 comparison of Safari Preview 9.1.1 vs 9.1 vs 9.0. http://beta.html5test.com/compare/browser/6622362e7251ac62/54b79a2e71e1c3a1/safari-9.0.html

Well in Firefox Nightly (v49) and the current Safari Technology Preview (5) CSS Grid is now enabled by default/unprefixed so you don't need to mess with any of that!

But for future reference you will likely encounter other things behind flags (prefixes are being killed thankfully but many things are still prefixed) so...

For features behind flags search in the URL/ominbox: For Chrome & Opera go to/search 'chrome://flags', for Firefox go to 'about:config', not sure about Webkit/Safari but they may not have any flagged features yet anyway. Then there will be a settings page with a bunch of features in development that you can turn on if you want to try them out, these can affect the stability of the browser so be warned.

For prefixes, just prefix the property or value with the vendor prefix (-ms-, -o-, -webkit-, -moz-) and use it as you normally would (there are occasionally syntax differences which you may need to look up). For example (and kinda redundant now):

body {
display: -webkit-grid;
-webkit-grid-columns: auto;
-webkit-grid-rows: auto;
}

There's a wealth of info for support for CSS and JS on caniuse.com, which i recommend checking out. ;)

Thanks Josh... most of that is what I've found. But, supposedly, there is a way to enable it in Safari (but, I'll try again with the most recent, if it's on by default!). Lots of stuff references turning it on in Safari, but I couldn't find any way to do so.

Hehe, thanks... but that's kind of the problem. I must be missing something fundamental, as I've never tried using experimental stuff like that yet. Every 'tutorial' I've been able to find doing searches like that just says to enable it with the -webkit- flag.

Looking at similar searches for other browsers, there seems to be a 'settings' page you can get to with such a flag to turn the experimental stuff on or off. I've not been able to find that for Safari. And, I've yet to find a tutorial that explains it. :)
