I got an HDR screen recently and kept feeling the colors were way too saturated. Then I noticed Chrome didn’t have that problem—turns out Chrome actually ships with color management built in. But I’m a Firefox guy. What do I do? Actually, Firefox supports color management too.

As we all know that Firefox 57 will rename to Firefox Quantum. It means the New version Firefox will use Quantum Engine instead the old one. Even throgh Firefox 57 is still in beta,but we can install it from PPA under Ubuntu. sudo add-apt-repository ppa:mozillateam/firefox-next sudo apt-get update sudo apt-get install firefox So here it is.

After I upgraded Firefox to version 55, I found that the old option: gfx.font_rendering.fontconfig.fontlist.enabled workaround no longer existed. Without that option I can’t display emoji correctly in Firefox.

The Fedora 25 here is the Gnome-Shell-based Fedora 25 release. Verdict first: after setup, Fedora 25 with Gnome-Shell is basically usable — and “basically” is doing a lot of work in that sentence.

Starting with Firefox 52, Firefox dropped all NPAPI plugins except Flash. Which means you can’t use Alipay in Firefox anymore. Sure, you could open Chrome. But if you hate Chrome like I do, there’s a way to work around it for now.

Firefox just updated to 44.0, and for Linux users that means a new problem. Fonts look like garbage. Like this:

I tried enabling full hardware acceleration for YouTube on Linux a while back in this post. If you unfortunately did the same, upgrading to Firefox 43 today probably broke YouTube video loading for you. First it’s this… Then it’s this… After digging around for a while I finally found the fix…

First, check whether your Firefox is even showing acceleration.

This is a stupid-ass problem that’s been bugging me for six months.

Like I [said before][1]… I’m stuck using a laptop with a damn 1366x768 screen. I could give you ten thousand reasons why this shitty resolution needs to die, but regardless, I’m using it right now. One big annoyance with this little thing is vertical screen real estate. Unity has done a fair bit of work on that front, but for someone who likes keeping the bookmarks toolbar visible, it’s still a bit tight… So I started looking into how to hide the Firefox bookmarks toolbar, tried a few add-ons, and only one actually worked. And even that one had problems: too twitchy, and every time the toolbar popped up the page would reflow. Super annoying, right? I asked around on G+ and got an answer: manually edit Firefox’s CSS. I found a userChrome.css file meant for Firefox 4; we’re on Firefox 29 now, but I tweaked it a bit and it mostly works.
