v1.19b
New live folders auto-fill with opened GitHub issues, PRs, or RSS feeds, and can be added via the sidebar. It also brings tab splitting by dragging, macOS native popover UI, an improved icon picker, plus security fixes and performance improvements.
Security
Various security fixes.
Fixed
- Fixed private mode windows having dark text on dark background in the sidebar.
- Fixed popup windows not showing at all on certain occasions.
- Other bug fixes and performance improvements.
Added
- Updated to Firefox 148.0
- Added live folders. Automatically fill your folders with opened GitHub issues, pull requests or RSS feeds. To add a live folder, click the + button in the sidebar and select 'Live Folder'.
- Dragging a tab on top of another tab for one second will now allow the option to split those tabs.
- MacOS users now get to use native popover UI, making the experience more consistent with the rest of the operating system.
- Improved the icon picker for folders, tabs, etc. It now let you select icons without closing the picker.
- Pressing the "Un-split" button while holding shift will not focus the un-split tab, allowing you to stay in the current split view.
Change
- Bluring the window will no longer close the urlbar if its open.
- Emojis at the space switcher will now be larger and more visible.
Theme
- Removed the
-zen-window-transform-originCSS attribute as it is not needed anymore

What's New in Web GPU (Chrome 146)
Chrome 146 introduces WebGPU compatibility mode for OpenGL ES 3.1, broadening accessibility across older devices. It also adds transient attachments, WGSL texture_and_sampler_let, and Dawn updates, plus new shader and validation improvements.
Support WebGPU compatibility mode on OpenGL ES 3.1
While WebGPU is designed to align with modern graphics APIs like Vulkan, Metal, and D3D12, many users have older hardware that does not support these standards. To bridge this gap and ensure broad accessibility, Chrome introduces a new opt-in feature called compatibility mode.
This mode lets you run WebGPU on older graphics APIs like OpenGL ES 3.1. By targeting a slightly restricted subset of the WebGPU spec, you ensure your web app is accessible to everyone, from the latest gaming rigs to older laptops and mobile devices. While starting with Android, the team is exploring support for other devices, such as ChromeOS with OpenGL ES 3.1 and Windows with Direct3D 11.
For many web apps, you can enable compatibility mode by passing featureLevel: "compatibility" when you call requestAdapter(). If your device supports Core WebGPU, Chrome will return a Core-capable adapter, but your web app will know to stay within the compatibility limits unless it enables the "core-features-and-limits" feature (or enables all available features). More complex applications might require minor adjustments to fit within the mode's restrictions.
// Request a GPUAdapter in compatibility mode.
const adapter = await navigator.gpu.requestAdapter({ featureLevel: "compatibility" }); const device = await adapter.requestDevice();See the WebGPU Fundamentals guide for detailed information about the specific architectural restrictions of this mode. Additionally, all WebGPU samples now support compatibility mode. You can also read the intent to ship.
Transient attachments
You can use the new TRANSIENT_ATTACHMENT GPUTextureUsage flag to create memory-efficient attachments. This lets render pass operations stay in tile memory, which avoids VRAM traffic and can avoid VRAM allocation for the textures.
By declaring a texture as transient (or "memoryless"), the GPU knows that it only needs the texture's contents temporarily—specifically, only within the current render pass. Moreover, because the texture's contents are discarded after the render pass, the driver may not need to allocate VRAM for it at all.
The following example shows how to create a transient texture.
const adapter = await navigator.gpu.requestAdapter(); const device = await adapter.requestDevice(); if ('TRANSIENT_ATTACHMENT' in GPUTextureUsage) { const transientTexture = device.createTexture({ size: [42, 42], // The TRANSIENT_ATTACHMENT flag indicates the texture content is temporary, // potentially keeping it in fast on-chip memory. usage: GPUTextureUsage.RENDER_ATTACHMENT | GPUTextureUsage.TRANSIENT_ATTACHMENT, format: 'rgba8unorm', }); }See the Hello Triangle MSAA - WebGPU Sample and the intent to ship.
WGSL texture_and_sampler_let extension
The WGSL language extension texture_and_sampler_let lets you assign texture or sampler variables to a let within a WGSL shader. This feature currently provides an alternative naming mechanism and prepares for bindless support where methods returning textures or samplers can be stored directly into local variables.
See the following example and the intent to ship.
@group(0) @binding(0) var tex : texture_2d<f32>; @group(1) @binding(0) var store : texture_storage_2d<r32float, read_write>; @fragment fn main() { let a = tex; var res : vec4f = textureLoad(a, vec2i(1i), 0); textureStore(store, vec2i(0i), res); }Dawn updates
The following new limit tiers are available:
- maxStorageBuffersPerShaderStage supports up to 16. See issue 366151398.
- maxSampledTexturesPerShaderStage supports up to 48. See issue 475255737.
SPIR-V validation is enabled by default on Android to provide an additional security layer and prevent driver instability from malformed input. See issue 473526182.
This covers only some of the key highlights. Check out the exhaustive list of commits.
