Hacks.Mozilla.Org: Safely reviving shared memory
At Mozilla, we want the web to be capable of running high-performance applications so that users and content authors can choose the safety, agency, and openness of the web platform. One essential low-level building block for many high-performance applications is shared-memory multi-threading. That’s why it was so exciting to deliver shared memory to JavaScript and WebAssembly in 2016. This provided extremely fast communication between threads.
However, we also want the web to be secure from attackers. Keeping users safe is paramount, which is why shared memory and high-resolution timers were effectively disabled at the start of 2018, in light of Spectre. Unfortunately, Spectre-attacks are made significantly more effective with high-resolution timers. And such timers can be created with shared memory. (This is accomplished by having one thread increment a shared memory location in a tight loop that another thread can sample as a nanosecond-resolution timer.)

Extension Spotlight: SponsorBlock for YouTube
Have you ever been engrossed in music or a great video when YouTube suddenly interrupts your experience to inject an ad? It’s jarring and ruins the mood of any moment.
[...]
A new SponsorBlock feature offers the ability to skip different types of unwanted sections like intros, outros, and those incessant pleas to subscribe to the channel. Ajay says future plans involve developing distinct section categories that will allow users to submit labels for different parts of the video, in case you want to skip forward or back to certain spots.
The SponsorBlock extension for Firefox is one of the more original content blockers we’ve seen developed in some time. It’s a perfect example of the creative problem-solving potential of browser extensions. So give SponsorBlock a spin and enjoy fewer interruptions while you let loose for your solo living room dance party set to YouTube music.
