gz83/thorium M156.0.8078.80

M156 Beta V1 Release!

on GitHub

Hello everyone, I am gz83, a collaborator on the Thorium browser project. Since Alex is currently unavailable to update Thorium, I have temporarily taken over the task, and this release is a minor update to the stable version of M156. The code is available here:

https://github.com/gz83/thorium

I think the current version is quite stable, and I'm only marking it as BETA because it hasn't been officially released by Alex yet.

Welcome to use Thorium. Please submit any issues you encounter in the main Thorium repository using the issue template:

Here are the release notes for this release:

(Due to space limitations, not all changes are fully summarized.)

Updated Chromium from 156.0.8078.28 to 156.0.8078.80.

Thorium changes

• Added Install CRX file to chrome://extensions on desktop and Android, requiring developer mode. Installing third-party CRX files directly from downloads additionally requires chrome://flags/#allow-offstore-extension-downloads (off by default). Signature checks, permission prompts, and extension policies remain enforced.
• Added setup guidance and a clearer disabled state for experimental Android extensions. Enable chrome://flags/#enable-extensions-android and relaunch to use them; they remain off by default.
• Fixed Android extension menus, toolbar recreation, and Incognito cleanup, including handling of multiple Incognito windows.
• Restored Chromium/system menu delays by default. Enable chrome://flags/#instant-menu-show to restore the previous 1 ms submenu delay.
• Added chrome://flags/#downloads-show-full-url to control full URL visibility on the desktop Downloads page; full URLs remain enabled by default.
• Fixed V8 snapshot generation for macOS ARM64 builds cross-compiled on Linux, and corrected the Thorium 2024 tab-strip gap above the toolbar, including in fullscreen.
• Corrected first-run branding on desktop and Android. --disable-thorium-icons now also applies to the Incognito new-tab page icon and favicon.

Chromium updates

• Integrated upstream security and memory-safety fixes, including stricter file-system access checks, cross-origin event isolation, and HTTP range-response validation.
• Improved rendering, media, WebAudio, and WebRTC reliability, with updates to V8 and other core components.
• Fixed Android extension-popup crashes with third-party autofill and improved file-picker and clipboard handling.

Build and maintenance

• Added native macOS x64/ARM64 smoke tests and fixed dependency-sync rebase conflicts when switching Chromium revisions.
