As well as templates, C++ has function overloading, so when a function is named in an error message it has to show all the arguments as well. And if it can't find a function variant that matches a call, it'll print out a "did

Yes, the compiler's error messages are extremely good. They often give correct and useful suggestions on how to change code to make it compile. This can be invaluable when dealing with trickier corners of the language such as explicit

It's more complicated than that. Firefox on Android uses much of the core code that desktop does. But sometimes new features do get enabled on Android a little later. One example is Stylo, the new style engine, which isn't enabled

Note that these kinds of things are typically highly dependent on machine/browser configuration and workload. So that bug's title is overly broad, power consumption is fine for many (most?) people.

How is Mozilla siding with Microsoft?

Mozilla acquire Pocket a while back. That might address your concerns, depending on what those concerns are.

Firefox now uses multiple processes too. By default Firefox is limited to one UI process and four web content processes. Chrome will use roughly one content process per tab (though that's an oversimplification). Firefox's choice t

Here's a blog post from this week about memory usage: http://www.erahm.org/2017/09/25/firefox-memory-usage-in-the-... That's a comparison on real websites rather than browser benchmarks.

Mozilla acquired Pocket a while back. So "shares with them" really means "shares with itself" :)

Strictly speaking, Stylo and WebRender fall under the Quantum project umbrella, as "Quantum CSS" and "Quantum Render", respectively. https://wiki.mozilla.org/Quantum has details. (The names are definitel

I think the minimum sizes were chosen because of a combination of (a) there was a much greater variety of hardware available then, and (b) people hadn't learned that fixing these sizes is better.

BMP isn't so trivial, largely because it's been extended multiple times while never having a proper spec. http://searchfox.org/mozilla-central/rev/bbc1c59e460a27b2092... has some of the gory details.

Firefox ships ~100 localizations. (See https://www.mozilla.org/en-US/firefox/nightly/all/ for the list.) I'm pretty sure this will be handled appropriately :)

From the blog post: "Set things up so that fatal warnings are off by default, but enabled on continuous integration (CI). This means the primary coverage is via CI. You don’t want fatal warnings on by default because it causes problems
