mconley commented on Firefox engineers discover a Windows Defender bug that causes high CPU usage   bugzilla.mozilla.org/show... · Posted by u/mconley
mconley · 2 years ago
TL;DR: Windows Defender had a bug that made certain system calls expensive on CPU cycles when Defender's Real-time Protection feature is enabled. After discovery, Mozilla reported this issue to Microsoft. Microsoft is releasing a patch that should result in lower CPU usage when using Firefox on sites like YouTube (a ~75% CPU usage reduction was noted when browsing YouTube in Firefox with the fixed version of Defender).

It seems like the HN submission form truncated the # from the end of the URL I linked to, which linked to the relevant comment. I'll try that here:

This is the Picture-in-Picture API it implements: https://w3c.github.io/picture-in-picture/

I am surprised that the API is modelled to only allow watching videos in PiP, while the old and mature Fullscreen API allows to put any element in full screen. These should be analogous. I don't see a reason why I can run a <video> in a small window, but not a <canvas> a <picture>, etc.

As the article mentions, Firefox is not currently implementing the Picture-in-Picture Web API that you linked to. Firefox's implementation is a browser feature only, and not exposed to the web at large.

I hate to be negative, but that will never happen with the current leadership at Mozilla.

They are simply no longer willing to disrupt the status quo, even to help their users. They are far more motivated to be "popular", and have a big "audience", and a respected "brand", than about sticking up for their users. The fact that they even think about software development in terms of "building an audience(?)" shows that they are way off course. The most important software we use that is actively developed is made by people who are primarily concerned with making good software, not with this pseudo public relations cargo cult corporate speak.

Hint: Go back and look at what Firefox used to be like 10 years ago, and notice the difference in culture.

The fact is, if Mozilla took a proactive stand against Google Apple and Microsoft, that would greatly increase their popularity.

The old Firefox was "irresponsible" by including a popup blocker by default, and upset a lot of people. Firefox also refused to support any of Microsoft's early web DRM. People said that not supporting DRM would lock users out of content, but it actually probably contributed to the death of those systems.

Google has been slowly clamping down on user freedoms. Just one example, Google removed the option to save html5 video[1] (I'm sure users were begging for that "feature"). I would honestly not be surprised if the UX clowns at Mozilla remove that function from Firefox as well.

How long until they remove the "view source" option because being able to view source is confusing to people who have never used a browser and it is used less than 1% of the time or some other flimsy justification?

There have been people within Mozilla who just want to abandon their own code and simply release a re-branded Chromium. Because they only care about their precious brand and keeping the donations coming, and they are truly terrible stewards of the software they have inherited. Besides, once they stop actually developing their own software, they will have lots of money leftover to give themselves bonuses and throw expensive galas.

This is just false.

I guess you're not aware of the content blocking work we've been focusing on lately?: https://www.theverge.com/2018/8/30/17800714/mozilla-firefox-...

Disclosure: I work for Mozilla on Firefox. I can say, without hesitation, that we definitely give a damn about protecting the user and protecting the health of the web.

This title is inaccurate. Mozilla is _not_ hiring a developer to work on Thunderbird full-time. See below:

From the post:

" The Thunderbird Project is hiring for a software engineer!

...

Please note that while the Thunderbird project is a group of individuals separate from the Mozilla Foundation that works to further the Thunderbird email client, the Mozilla Foundation is the Project’s fiscal home. The Thunderbird Council, separate from Mozilla, manages the Project and will direct the software engineer’s work."

I was actually thinking about switching to Chrome because of GMail (or rather Inbox). When I open Inbox in Firefox, it can take 20 to 30 seconds for the cursor to stop spinning and I have a 300 Mbps connection.

Hi! Firefox engineer here. Check out this reply: https://news.ycombinator.com/item?id=15371068

If you're interested in helping me figure out what's going on here, feel free to send me a performance profile.

I've been running Nightly and experienced the same thing with inbox. If I attempt to interact with it before fully loaded, inbox will freeze up for minutes at a time. Love everything else about nightly, this is my biggest issue.
mconley · 8 years ago
Hi! Firefox engineer here, and I want to understand why your Firefox is misbehaving.

Would you be willing to provide us a performance profile? Instructions are here: https://developer.mozilla.org/en-US/docs/Mozilla/Performance...

Feel free to email it to me if you don't want to post the link publicly. I'm mconley at mozilla dot com.

ledgerdev · 8 years ago
I would love get rid of chrome and to switch back to firefox as my everyday browser, but simply can't get over how messy/ugly the tabs(even in compact theme) and window title look compared to what chrome does with tabs and title bar, and lack of window title bar.
mconley · 8 years ago
If you enter customize mode, you can:

1) Choose one of the compact themes, which have square tabs instead of curved

and

2) Re-enable the title bar

I'm glad this comment sits at the bottom of this post. It's reflective of how the zeitgeist actually cares about this issue.

The Battle For the Net website mentions a vast range of online companies who apparently stood in solidarity to take action on this day.

* Github: a blog post displayed on your feed.

* Etsy: Nothing.

* Kickstarter: Nothing.

* Netflix: Nothing.

* Twitter: Nothing.

* Vimeo: A featured video on the landing page.

* Reddit: A tiny blurred logo.

* Hacker News: A grey bar!

* Mozilla: Nothing.

* OkCupid: Nothing.

What a great display!

> * Mozilla: Nothing.

Really not sure what you're talking about here.

Along with this blog post: https://blog.mozilla.org/blog/2017/07/11/defending-net-neutr...

There's a snippet on about:home about Net Neutrality for every Firefox user:

We've got a form here to make it easy to submit your comments to the FCC: https://advocacy.mozilla.org/en-US/net-neutrality-comments

We even voiced 9hrs worth of Net Neutrality comments that had already been submitted: https://www.youtube.com/watch?time_continue=1&v=twksX_S3vkg

The most recent episode of the IRL Podcast is centered completely around Net Neutrality: https://irlpodcast.org/episode2/

Ok now I have to do some embarrassing backtracking. In a clean profile I don't get the problem. Sorry for publicly whining about your product, which apparently works fine.

I'm not sure what I've done to make it not work here, but this profile dates from a long time ago so maybe it's just cruft or an extension behaving oddly. I'll switch to using a clean profile. Sorry again and thanks for your attention.

mconley · 8 years ago
All good. Thanks for checking. :)
