hopefully there's a way to Disable that rediculous feature

How is it ridiculous? I actually think it's a good idea. I hate when one of my tab auto start a video out of nowhere and then i don't know which tab is responsible for the sound playing.

I've installed Firefox 40 on Win10 and noticed that they now also allow pages to reserve important keyboard shortcuts like alt+F (e.g. youtube uses it for full-screen). Because when Youtube flash player was doing it for ctrl+tab it wasn't annoying enough. Will they ever learn?

This is in Nightly under E10s by default, but will work in any version (39+).  This improves scrolling drastically.  You set  layers.async-pan-zoom.enabled to true in about:config.

Scrolling in Firefox to get a lot better thanks to APZ

Yeah, APZ works great with E10S, but release versions don't have E10S, so enabling it will probably lead to slower performance.

Also it's extremely buggy, so if you do enable it expect crashes, rendering glitches and odd scroll issues.

might be for some that spend there entire time on Youtube type pages, i dont

The sound Icon is only there if there's some kind of video playing in the background (e.g. youtube), so if you never have pages with videos open as you claim, then you'll never see the Icon, so I don't see what there is to complain about.

Use x86 version, will crash If more than 3,5GB RAM will be addressed :p

This is mane future of x64 software ;) I think You are hit by bug where TY movies leak RAM, need to wait for fix.

But the x86 version won't go above the limit, the x64 version seems to eat as much RAM as it wants pretty much freezing the system when the swapping starts. It can't be that a javascript or page gone wrong can take down the entire system.

The x86 version can't go above the limit, it'll crash, it's not a choice.

I know, I meant won't go as because physically limited. And my issue isn't with just with videos, I've had it happen on other kind of pages and especially on large IMGUR galleries but when it happens it takes me minutes to manage to kill the firefox process because of all the endless swapping it causes.

Unless something pretty bad happens, yeah. The re-write of their media architecture made it more standards compliant (And broke a few websites that didn't expect that), and made it use less memory and be more reliable, so it'd have to be a big issue to disable it.

That being said, even if there were bad bugs, that would be the norm for MSE implementations, Chrome has some bad bugs, and I've managed to deadlock the entire Safari parent/child processes trying demos before.

Is there any particular reason why I get an error 505 No permission when I try anonymous FTP access to the Nightly directory ftp://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-trunk Its been unavailable for a couple of days now. It seems everything below  ftp://ftp.mozilla.org/pub/ is out of bounds?

Oh and how come the 64bit Nightly 43.0a1 file downloaded from the Firefox Nightly web page today 2015-08-11 at 11am GMT, once installed, displays as 42.0a1 (2015-08-10) in About Nightly? Inquiring minds want to know.

Lastly, can I just first say how much I do not like the fact that Firefox Nightly does not just issue a warning about unsigned extensions, it will unload them and prevent a re-install.  I have authored my own insignificant extension, that does less than nothing but can no longer be used in Nightly Builds.  Developer versions of two extensions I usually run in Nightly have also been unloaded and suppressed.  Not cool.

i have been having problems with mozilla's ftp for several days, i can't directly open mozilla.org/firefox/releases it takes me back to the root directory. Sometimes i can't even click in to /firefox/ sometimes not /firefox/releases or /firefox/nightlies something is really messed up with their ftp server. I have tried using flashfxp and chrome.

    • If its the devs fault you would think Unreal would help M$ take full advantage of Unreal and work with them to fix the performance issues. Otherwise they are catching unwarranted bad press.
    • Thanks for the advice guys, I'll give my current GPU a clean and then run the benchmarks to see how similar it is. Hopefully a bit of a clean-out will help it last a bit longer.
    • Pretty sure those will still be in this game. The series' well-explored psychosis themes will return as well.

    • Microsoft making much needed change to Windows 11, 10 Patch Tuesday security updates by Sayan Sen Recently, Microsoft delivered its latest Defender patches for Windows 11 ISOs. These definitions are released from time to time alongside the general security updates available during Patch Tuesday. Speaking of Defender, the company has now announced another important change that affects how security updates are delivered to enterprise devices running Windows. According to a recent announcement, Microsoft Defender for Endpoint's endpoint detection and response (EDR) updates will no longer be bundled with the monthly Windows security updates or Patch Tuesdays. Instead the company is shifting delivery of these updates to Microsoft Update, bringing EDR servicing in line with several other Microsoft Defender components. If you recall, Microsoft last year moved PowerShell updates to Microsoft Update (MU) as well since it provides automatic updates for Microsoft products and services. Thus the move is intended to allow Microsoft to deliver EDR improvements and security enhancements independently of the OS's regular monthly update cycle; this should enable faster deployment of protection updates without requiring organizations to wait for the next Patch release. For those unfamiliar, Microsoft Defender for Endpoint's EDR capabilities are designed to help organizations detect, investigate, and respond to advanced threats across managed devices. Keeping these components updated is critical for maintaining protection against evolving attack techniques. The rollout has already began for Windows 10 devices in late May 2026 (last month) and Microsoft says it will gradually expand support to Windows 11 and the remaining supported Windows versions over the coming months. The company expects deployment across Windows 10 and Windows 11 to be completed by fall 2026 or around Q3 of this year. Once the transition is complete, EDR updates will be delivered through Microsoft Update using KB5005292, provided the required prerequisite updates have already been installed. Microsoft is also introducing a new Defender Update Service as part of the change. Following installation of the first update, devices will automatically create a new directory located at %ProgramData%\Microsoft\Microsoft Defender\Defender Update. Microsoft notes that restarts may occasionally be necessary in case of "rare" failure scenarios. For most organizations, the tech giant says no action will be required as long as Microsoft Update is already permitted within their update management strategy. Admins who rely on manually deployed update packages, however, will need to adjust their processes to ensure the new Defender update package is included. Microsoft also recommends reviewing internal documentation and notifying helpdesk and security operations teams about the updated delivery mechanism to avoid confusion during the transition. As a prerequisite, the tech giant notes that systems must be running Sense version 10.8798.25857.1000 or later and have one of the following Windows updates (or later) installed: Win11 24H2 KB5062660 (2025-07 Cumulative Update Preview) Win11 23H2 KB5062663 (2025-07 Cumulative Update Preview) Win11 22H2 KB5062663 (2025-07 Cumulative Update Preview) Win10 22H2 KB5062649 (2025-07 Cumulative Update Preview) Win10 1809 KB5063877 (2025-08 Cumulative Update) Server 2019 KB5063877 (2025-08 Cumulative Update) Server 2022 KB5063880 (2025-08 Cumulative Update) Server 2025 KB5063878 (2025-08 Cumulative Update) As always, organizations should verify that their update policies align with the new servicing approach before the broader rollout reaches all supported Windows platforms later this year. In case of major problems, the EDR update can be rolled back to the inbox version stored in %ProgramFiles%\\Windows Defender Advanced Threat Protection (ATP) using: MpCmdRun.exe -RevertMde -Product Edr -ToVersion Inbox For those who have access to the Microsoft 365 Admin Center portal, you can view the message here under ID MC1381119.
