hmm why would firefox start doing this without updating and any changes to settings/drivers/hardware.

SfZgX.jpg

tried fresh profiles, reinstalling firefox and video drivers. issue is on both 32 and 64 builds and does not occur on other browsers.

incase anyone has this issue, I solved it by removing windows update kb 2670838 that came with IE10.

Azure and DLBI both sped up rendering, you can see as much from tests.

No disrespect Decryptor, and not because your a Mod, but because you seem a really cool guy here in the forums, those are just benchmarkings that in real life matter little. again 1ms faster, oh my god!!!

It's like when they implemented "Load tabs only when selected", that was just to hide the poor performance on Firefox when booting!!!

The feature is nice but it's timing was exactly when people were complaining about start times. And yet on a i5 2500k, with 16GB Ram, and Nvidia 570, with this option off and no tabs to load, Firefox can take 5 seconds to load. Now you might say, "Oh but 5 seconds pass on a blink of an eye", yes but IE9/10 is instant, why can't Firefox be too.

And this is just one example, if sure if I think a little harder, I'll find many more!

Now don't think I'm hatting Firefox, cause I'm not, I want it to be faster on all levels, but Mozilla seems more focused their own OS and mobile stuff than what made them popular on the first place, their DESKTOP BROWSER!!!

I'm not talking about 1ms here or there, I'm talking about things getting 10x faster (One "benchmark" went from 1fps to about 30fps on my Mac with the SVG DLBI stuff) In the best case, it won't help much (because it's already the best case), in the worse case you see a huge improvement.

And on my computer (Which funnily enough is an i5 200k with 16GB of RAM and a GTX 570) Firefox launches in <2 seconds (Nightly is closer to 1s, but it also has less tabs/extensions to load)

Edit: And their mobile stuff is driving desktop enhancements, All the work on off the main thread compositing (for example) is driven by a need to make the mobile UI more responsive, work of which also applies to the desktop.

Should I post regarding Important bugs landed but backout like currently did or not?

  • Like 2

the more info, the better!

Then I will cover backout information of Important bugs like I do as well since it sometime indicate that they will land sooner in exception cases it is not but majorly it is. So it will be help for users I think.

Thanks Zlip :)

I'm not talking about 1ms here or there, I'm talking about things getting 10x faster (One "benchmark" went from 1fps to about 30fps on my Mac with the SVG DLBI stuff) In the best case, it won't help much (because it's already the best case), in the worse case you see a huge improvement.

But that's the problem, You're assuming in the worst case you'll see huge improvements, when in fact the "laggy UI" is still there, what good is a 1000hp engine is, if the body can't hold more than 100hp without starting to fall apart?

In most i5 and i7 the problem is just hidden because of so much HP, but as soon as you get a less performance CPU and a intregrated GPU you'll notice how laggy Firefox UI is! The body is just top heavy!

And on my computer (Which funnily enough is an i5 200k with 16GB of RAM and a GTX 570) Firefox launches in <2 seconds (Nightly is closer to 1s, but it also has less tabs/extensions to load)

I'm not seeing that in my end, sure if you "open a new window" with Firefox as a process sure, but closing Firefox and re-opening it does take seconds and not 1.

Edit: And their mobile stuff is driving desktop enhancements, All the work on off the main thread compositing (for example) is driven by a need to make the mobile UI more responsive, work of which also applies to the desktop.

I think that decision is wrong and that's why we are where we are.

It should be the Desktop browser the priority.

Seriously how many users does Mozilla mobile have? On the iPhone? There's no Firefox browser (I have to use Opera)... On the Windows Phone? Not that I know about.. On Android? How many? 100k? 200k? A million?

How many Firefox Desktop users? Chrome is eating Firefox share and they are concerned with a very small % of their users on mobile platforms (and like I said before not even that many, actually just one, Android) and then they backport changes to Desktop months latter, if ever?

And using the few resources (man power) they have to build their own mobile OS? Great another dead project from the start! There's already 3 main OS's for mobile, then there's RIM, ex-Palm, etc... There's just no point!

This is Mozilla wanting to be relevant in other areas. But not only are they failing on doing so, they are neglecting their champion!

[update] Firefox Mobile share in %: http://marketshare.h...d=0&qpcustomd=1 0.1%

Posting only two bug currently because these are SUPER AMAZING::

https://bugzilla.moz...g.cgi?id=799315

It is to enable system wide codec to support MP3 and H.264 codecs for Windows Vista+, it is preferred off due to few reasons.

To enable it, go to about:config and toggle this to true:

media.windows-media-foundation.enabled

Remember it is in Inbound which is not merged to mozilla-central yet so try it after one or two days.

What I like the most about using Nightly builds is that you never know what fixes are included untill hours after you update.

I think we can track the builds from TBPL and see which Nightly build cooking and then estimate with update release time. Means build take times. So overall not very surprise process for me at least.

This is true but there was a time when the builds thread was updated as it should be. I long for those days. Without the updates all they need to do is post the change log for the build.

Agree!!!!

what you should do is just copy what Arjen or Peter6 Nightly Threads ( Bugs etc ) an Paste it into the forum, that way i wouldnt have to visit Mozillazine forum anymore

    • Signal accuses UK government of using child safety as cover for mass surveillance by David Uzondu Recently, the UK's Home Office announced a sweeping set of proposals to make Britain the "first country in the world" where children cannot share or view nude photos on their smart devices, an initiative that authorities claim will protect children from online predators and combat pornography. In response, Signal believes that while the government must keep children "safe" and "protected," it should do so through social services and education, not by "surveillance, funding cuts, and cover-ups." The company called the plan "dystopian" and warned that it violates everyone's fundamental right to privacy, arguing that scanning on the presumption of nudity will only strengthen the market dominance and data control of giant corporations like Apple and Google. The statement continues by accusing the government of hiding its true intentions under the guise of child safety. Signal argues that the Home Office is building an invisible surveillance infrastructure that remains ripe for exploitation by future administrations and authoritarian regimes. According to the company, this aggressive approach completely ignores the actual needs of young people, such as properly funded schools and mental health services. Tech companies like Apple and Google have a three-month window to implement these mandatory device-level filters across the United Kingdom. If these tech firms refuse to comply with the mandate, the government will pass emergency legislation to force them to comply, threatening massive fines and even going after the CEOs of these companies with criminal charges. The technology will work by blocking explicit images directly on the operating system of all smartphones and tablets by default. This system monitors the device camera and third-party apps to intercept nudity before anyone can upload or send the image. Adults can still view explicit content, but only after completing a strict age verification check to unlock their devices. Several bodies like the NSPCC and Barnardo's praised the Home Office's decision, arguing that device-level intervention stops the cycle of grooming before it starts. The Internet Watch Foundation (IWF) also supported the policy, claiming that tech companies can implement on-device checks "without threatening privacy or collecting any data."
    • Did you watch the keynote? It is way beyond what is described in this article. Looks interesting. Now it is time for them to deliver unlike what happened in 24.

    • Incredible deal gets you free NVMe 512GB SSD with AMD AM5 B850 motherboard for only $150 by Sayan Sen Earlier this week we covered the story of an interesting PC case wherein you can build two full-size computers inside it as in it can house and run an AMD and an Intel system simultaneously. Speaking of building PCs, these are hard times to make one for sure as prices are often very high except during flash sales or discounts. If you are in the market for a 1080p gaming PC then Nvidia's 8GB RTX 5060 Ti is currently on sale for just $330 and you get the latest James Bond game too, for free. Speaking of which, right now there is another incredible sale going on as we can get a free 512 GB NVMe SSD from TeamGroup in the form of the G50 alongside the purchase of an AMD B850 socket AM5 motherboard for only $150 (purchase link under the specs table down below). Getting an AM5 motherboard now in 2026 will be a wise investment for sure, especially since AMD confirmed its commitment to support the socket till at least 2029. The MSI PRO B850M-P WIFI is a micro-ATX motherboard that is compatible with AMD Ryzen 9000 series processors. Since it is AM5, the motherboard works with DDR5 memory and includes MSI’s Memory Boost technology, along with EXPO and XMP support. Connectivity features include built-in Wi-Fi 7 paired with a 5G LAN solution. The board offers a PCIe 5.0 M.2 slot with MSI’s EZ M.2 Shield Frozr II thermal solution, that is said to help maintain SSD performance by providing ample cooling against overheating. The technical specifications of the MSI PRO B850M-P WIFI motherboard are given in the table below: Specification Value Form Factor Micro-ATX (mATX), 243.84 × 243.84 mm Chipset AMD B850 Socket AM5 Supported Processors AMD Ryzen 9000, 8000, and 7000 Series Desktop Processors Memory Slots 4 × DDR5 UDIMM Max Memory 256 GB Memory Speed DDR5 8200–5600 MT/s (OC), DDR5 5600–4800 MT/s (JEDEC) Display Outputs 1 × HDMI 2.1 (up to 4K 60Hz) 1 × DisplayPort 1.4 (up to 4K 60Hz) PCIe Slots 1 × PCIe 5.0 x16 (CPU) 3 × PCIe 3.0 x1 (Chipset) Audio Codec Realtek ALC897 Audio Channels 7.1-Channel High Definition Audio M.2 Slots 3 × M.2 slots M.2_1: PCIe 5.0 x4 (CPU) M.2_2: PCIe 4.0 x4 (CPU) M.2_3: PCIe 4.0 x2 (Chipset) M.2 Device Sizes M.2_1: 2280/2260 M.2_2: 2280/2260 M.2_3: 2280 SATA Ports 4 × SATA 6Gb/s RAID Support SATA: RAID 0, 1, 10 NVMe: RAID 0, 1, 5, 10 Rear USB Ports 4 × USB 2.0 2 × USB 5Gbps Type-A 1 × USB 10Gbps Type-A 1 × USB 10Gbps Type-C Front USB Headers 4 × USB 2.0 4 × USB 5Gbps Type-A 1 × USB 10Gbps Type-C LAN Realtek 8126VB 5Gb Ethernet Wireless Networking Wi-Fi 7 (802.11 a/b/g/n/ac/ax/be) Tri-band 2.4GHz / 5GHz / 6GHz MU-MIMO, MLO, 4KQAM Up to 2.9Gbps Bluetooth Bluetooth 5.4 Internal Power Connectors 1 × 24-pin ATX Power 1 × CPU Power 1 × PCIe Power (8-pin) Cooling Headers 1 × CPU Fan 1 × Combo Fan/Pump 3 × System Fan RGB Headers 3 × Addressable RGB Gen2 (JARGB_V2) 1 × RGB LED (JRGB) Additional Internal Headers 2 × Front Panel (JFP) 1 × Chassis Intrusion (JCI) 1 × Front Audio (JAUD) 1 × COM Port (JCOM) 1 × JDASH Tuning Controller 1 × TPM 2.0 Header The free TeamGroup T-FORCE G50 NVMe SSD is a PCIe Gen4 and as such it promises to deliver sequential read speeds of up to 5,000 MB/s, helping accelerate game loading, file transfers, and everyday computing tasks. The SSD features an InnoGrit controller and SLC caching technology to support consistent performance. An ultra-thin, patented graphene heatsink is included to aid in heat dissipation. The NAND flash is based on TLC which means it has plenty of endurance up its sleeve. The random performance may not be as amazing as other drives with DRAM though. Still it should be very good since it can access system memory via HMB to use it as its DRAM cache.

    • RapidRAW 1.5.7 by Razvan Serea RapidRAW is a beautiful, non-destructive, GPU‑accelerated RAW image editor designed for speed and simplicity. It uses a lightweight (~30 MB), efficient code base built with Rust, React and Tauri. Ideal for Lightroom workflows, it offers rich editing tools—exposure, contrast, highlights, shadows, whites/blacks, tone curves, HSL mixer, dehaze, vignetting, film grain, sharpening, clarity and noise reduction—processed in real-time on the GPU. Features include intuitive masking (brush, linear, radial, AI-powered subject and foreground detection), generative edit layers (via ComfyUI), 32‑bit precision, and full RAW format support through rawler. RapidRAW also provides library management (folder navigation, ratings, metadata, EXIF viewer), batch operations, export presets (JPEG/PNG/TIFF), sidecar editing (.rrdata), undo/redo history, customizable UI themes, smooth animations, resizable panels, and preset copy/paste. A modern high-performance Lightroom alternative with polished UX and creative tools, RapidRAW brings powerful photo editing to photographers seeking speed, responsive GPU feedback, and streamlined workflows. RapidRAW v1.5.7 release notes: This update serves as a direct follow-up to the core architectural migration introduced in v1.5.6. While the transition to a more modular state management system marked a significant step forward for RapidRAW's stability and long-term maintainability, it also introduced several edge cases and regressions within the library and editing workflows. This release focuses on addressing those issues, with a particular emphasis on a complete overhaul of library performance to ensure smooth and responsive browsing following the refactoring. It also resolves inconsistencies in the copy-and-paste workflow and expands RapidRAW's accessibility by adding support for eight additional languages.
