Zen Browser says Boost sharing is available. You can share a Boost, a customization you've made for an individual website, so someone else can use it.

The team also says it’s been improving performance, with more improvements on the way.

Zen Browser 1.23.4b is out. It adds an updated OneCRL block list and fixes a batch of sidebar, window, and crash bugs.

Mozilla blocked compromised eMudhra intermediate certificates through OneCRL on October 17th and sent the blocks to clients through Remote Settings the same day.
