> Firefox 146 also now makes Firefox Labs available to all users, Firefox on macOS now has a dedicated GPU process by default, dropping Direct2D support on Windows, support for compressed elliptic curve points in WebCrypto, and updated the bundled Skia graphics library. Firefox 146 also has some fun developer enhancements like support for the CSS text-decoration-inset property, the @scope rule now being supported, CSS contrast-color() function being available, and several new experimental web features.

GPU Rendering is Not Good For Battery Life (Score:3)
Video playing aside, using a GPU for rendering a web page will likely cost you in battery life. Recently, I tried Basilisk, and noticed how much faster it seems than Firefox, now.

As Iâ(TM)ve always said, best place to hide cryptography tech is between two rendering technologies.

Compressed elliptic curve points is not some crazy secret or complex thing to be making up conspiracy theories about. The nature of elliptic curve cryptography is that knowing the curve and the x coordinate, there are literally only two possible y coordinates, and a single bit signals which of the two possible y coordinates to use, allowing you to reduce, say, 512 bits of key coordinate down to 257 (256 for the x, 1 for the y), at a trivial cost to compute y from x before doing the rest of the math.

It should be out tomorrow at 6 AM PST (USA) unless last minute issues come up which are rare.

But not on its official public web site and internal updater. Until those offer v146, then it is not officially out.

I use ctrl +/- in Chrome/X11 and things look fine to my old eyes.

Also Ctrl-MouseWheel works a treat.

How well does X.org do with a dual screen system where one is 4K and the other is 1080P? For folks running laptops this sort of scenario is increasingly common, and X11 just doesn't do it very well.
I'm contemplating buying a 4K monitor and my main concern was how well X11 and the various desktop environments do hidpi. Having switched to Wayland, though, and with Firefox natively on Wayland and supporting fractional scaling, it makes the purchase a bit more comfortable.

What Problem do you have with that scenario? I find xrandr very versatile in configuring me all sorts of display combinations.
And like others wrote already: It was a brilliant idea of the X11 design to separate window managers and applications painting into windows. Really would not want to miss that.

I had a problem of the screen configuration resetting about a quarter of the time the system went to sleep mode or rebooted. Since upgrading to a newer version of Kubuntu that uses Wayland, I haven't had the issue.
I have a 1440p monitor paired with a weird resolution ultrawide, on a nVidia card. A few months ago I started running 2 GPUs. One monitor I have plugged into the integrated AMD GPU and the other monitor is the the nVidia card.
Wayland handled the weird configuration seamlessly. No problems with dri

You've tried running screens with very different dpi then? If you have a window running at hidpi on the 4k and drag it over to the 1080p, what happens? Will the app get scaled automatically (hopefully the toolkit redraws instead of everything being blurry). My understanding is X11 cannot deal with that scenario at all, xrandr notwithstanding. But I've never tried it myself. Will have a 4K monitor to test with in the new year.

Just fine, thank you. You've just described my desktop setup for probably the last 10 years.
Re: (Score:2)
That's good to know. So you can run hipdi on the 4k with scaling (possibly fractional scaling) and normal dpi on the 1080p then? things don't get all blurry on the 1080p when X11 tries to downscale the screen?

I have four monitors hooked up to my graphics card. From left to right, an Acer 1920x1080 display, an LG 1920x1080 display, a Samsung 1920x1200 display, and a Dasung PaperLike e-ink display whose native resolution is 3200x1800 but which I'm software-scaling to 1600x900.
No issues whatsoever with this setup and X11.
Re: (Score:2)
Do any of those monitors use hidpi and scaling that's independent of the other monitors?
Re: (Score:2)
That's the exact problem I have. Windows does it without even asking. My second monitor is actually a 4k tv for watching movies. Supposedly you can tweak xrandr and make it work but frankly it's not worth my time.
Re: (Score:2)
Don't use xrandr directly. Use arandr which gives you a nice GUI to configure the monitors. Once you're happy with the layout, you can save it as a shell script (that under the hood does invoke xrandr) so you can replicate the setup each time you log in or each time the system boots.
