The Mozilla tech blogs are always a good read. Informative and easy to digest. I can only think of one other company blogging with similar consistency/quality: Cloudflare. Firefox performance has seen tremendous gains since their Project Quantum efforts. It mostly feels on par with Chrome for me pretty much everywhere. There is one glaring omission though: a single company where I have problems with FF on multiple ap…

I was perfectly fine with Chrome's usability until I started getting a `Hold Command + Q` to quit` prompt on my Mac. Before then, I hadn't even considered the possibility that an application could block me from quickly and easily quitting out of it. Now I have to hold the key combo or double tap it to quit Chrome, and it is the only application I have to do that for. It's so annoying.
I'm surprised that functionality isn't possible to disable, but tbh I really like it. Too many times a finger slip turns Cmd+W into Cmd+Q and suddenly I'm lost a whole pile of tab state, possibly even half-submitted forms. Yuck.
Another possible workaround is to go to System Preferences > Keyboard > Shortcuts > App Shortcuts and create a new shortcut. You can specify that in the app Firefox, the menu item “Quit Firefox” should have the shortcut ⌥⌘Q. Then a normal ⌘Q should do nothing.

I have the opposite experience with YouTube. With an AMD GPU on Linux, Chrome churns, drops frames, and stutters horribly on even 1080p videos at 30fps. Firefox, meanwhile, handles 1440p60 video with no problem. Even two such videos simultaneously, on separate monitors. Chrome became inexplicably better for parts of early 2019 (I did not note which versions), but starting 2 or 3 months ago Chrome returned to being un…
When chrome slows down for me, it normally means I need to run clear browsing history, delete cookies, cache, logins, etc. I have modern hardware, on both linux/windows same issue. But using res on reddit and click "show images" you can tell chrome isn't as fast as other browsers, firefox/brave are visually faster/smoother in scrolling with pics. Hell, even firefox focus is faster on android. But I like chrome addons…

have you double checked whether firefox is set to use your gpu or not, for video?
Neither Firefox nor Chrome under Linux are capable of using GPU for video decoding. Only some distribution-specific Chromium builds do.

Diversity and multiple implementations are essential for the web IMO. V8/Blink/Chromium are not independent community projects, but firmly in the hands of Google. Chromium being the only viable implementation would put too much control in the hands of a single company (regardless of which company that is, Firefox being the only implementation would be just as bad). It's redundant effort, but it also enforces consensu…
Also a much slower one - on PDFTron's benchmark, WASM is half as fast as PNacl for me: https://www.pdftron.com/benchmarks/pnacl-vs-wasm/ .
It's nothing fundamental about WASM; in fact they state that the actual computations are slightly faster.

To be fair i think this is an exercize in vanity and why not say it, stupidity. Javascript VM´s these days are fairly complex beasts with huge amount of man-hour and expertise. Also technically this would be a inferior solution as compared to what V8 did with its interpreter in Turbofan (and SpiderMonkey are doing now as presented in the article), by generating pure assembly through the turbofan backend (the same tec…
There's already a JIT for JS coded in Rust: https://blog.mozilla.org/javascript/2017/10/20/holyjit-a-new... The overall goal is to have Firefox recoded in Rust, why would a JavaScript interpreter be left out? https://wiki.mozilla.org/Oxidation That's the whole point of Oxidation.
To clarify: it's a proof of concept, not a full JIT for JS. If you want to follow that project, it lives here: https://github.com/nbp/holyjit.

I'm waiting to hear about when they start to rewrite their JS interpreter in Rust. It will make things kind of interesting, especially if it becomes a stand-alone capable JS inrepreter.

Note that not everything can be easily rewritten in Rust due to the existence of lots of C++ code using macros and templates. Getting such to interact with any other language than C++ is painful.
