Only thing I worry about is whether less computer literate people are aware of what’s going on. Particularly whether they know where their downloads have gone once they are finished. Would it be a bad idea to have a doorhanger drop down once downloads complete to ensure users know where it’s gone?

As mentioned in the post, we’re using less SVG, in favour of pre-rendered images. It’s possible we could do something tricky with canvas down the line (to dynamically generate the images on the fly), but that’s not a v1 target.

Background tabs do not have curves so as to reduce the noise in the tabstrip, and to make it easier to identify which tab you’re currently on. See the specification here.

I’ve been using the curvy-tabs theme for several weeks now, and usually have 50+ tabs open, and I haven’t run into any nightmare issues yet. Have you?

Why are you using SVG instead if Canvas if you care about performance?
Why background tabs didn’t have tab curves? It will be a nightmare if we have more tabs opened…

You’ll need to install it from here, since you’re working off of a Nightly:

https://github.com/bgirard/Gecko-Profiler-Addon/raw/master/geckoprofiler.xpi

Once installed, it’ll appear in your nav-bar. I’d like you to open and close a tab a few times, and then click on the profiler button, and choose “Analyze”. Then, in the left-pane, there should be a button that says “Share”. Click on that to upload your profile. It should return a link. Once you’ve done that, either paste that link here in the comments section, or email it to me (see the Contact section of my blog).

I tried both – “Use hardware acceleration when available” enabled/disabled. Seems like it’s the same. Maybe it’s not hardware acceleration, but animation itself? Maybe it needs more frames? Or maybe it’s related to new tab’s recent pages quick dialer? Now I can see ~3frames of animation going on.

The RB-Stats extension was an experiment / exercise to see if we could get the Review Board extension framework working.

The extension framework is now available in the release version of Review Board, but the extension is almost certainly broken for it.

You can see the old code here: https://github.com/mikeconley/RB-Toy-Extensions/tree/d060963287fc1b25fd07397cd19dec38a0649c1d/rbstats

If you wanted to polish it up and get it working again, I’d be happy to answer questions about it.

I believe it will support Metro, since we have support for Metro in Nightly, and UX is based off of Nightly. Give it a shot and let me know!

Do you have Hardware Acceleration enabled? Can you see if disabling[1] it helps performance and let me know?

Thanks,
