Why am I seeing this Ranked on source trust — TechPowerUp
It ranks mainly on source trust: TechPowerUp is the most reliable outlet we track on this subject, and is the only one on the story so far.

| Factor | Weight | Score | Contribution | Where it came from |
|---|---|---|---|---|

| Pickup rate | 0.20 | 0.00 | +0.000 0% | One counted organisation, so there is no spread to measure — nothing has picked this up to set a rate. |
| Freshness | 0.20 | 0.81 | +0.162 33% | Halves every 10 hours from the newest item on the story. This is the only factor that rewards a story for nothing more than being recent. |
Corroboration counts distinct organisations, once each, and only from tiers 1 and 2. Freshness halves every 10 hours, so this ranking is a snapshot and will differ at the next build.

What happened
Mozilla has officially updated Firefox, releasing version 156 for macOS, Windows, and Linux and adding several improvements to the open-source browser that should make it significantly easier to live with. Firefox 156 can be downloaded directly from Mozilla's website, and existing Firefox can auto-update using their preferred software manager or Firefox's built-in updater where applicable. The headline changes to Firefox all relate to performance, with a claimed 45% faster start-up for the built-in PDF reader, improved memory and CPU usage when displaying scaled JPEG images, and H.264 decoding for video calling using WebRTC on Arm64 processors.
