Comment on: CSS: The bomb inside your inbox
I view email in Thunderbird and have uBlock installed. Sadly the CSS Exfil addon for Firefox does not exist for Thunderbird but I view emails in plain text either way.

It was never allowed. Microsoft just started doing it in their email client and obnoxiously made it default. There was no standards process where anyone spent time considering the potential downsides with the aim of making HTML email practical and secure.HTML email is just something that people semi-randomly do. It should be rejected/ignored if you are at all concerned about privacy and/or security.

After writing a long article, creating videos, images, and no doubt doing multiple rounds of edits... why should an author also have to ensure that their publication works without JS?From what I can see, they're doing so codeblocks have proper highlighting but also can be copied & pasted. It's a reasonable choice.They're not lazy.

Developers building event‑driven, serverless stacks are frustrated by webhook‑only integrations that force them to maintain extra infrastructure. EventSync converts those webhooks into a simple, pull‑based /events endpoint, letting teams retrieve change events on demand with minimal setup and zero webhook maintenance.
Employees often feel alienated from the dev team, asking 'What do they even do?' while executives make costly layoffs behind closed doors. CodeClarity gives non‑technical stakeholders instant, digestible insights into ongoing software work and decision impact, aligning expectations and fostering a collaborative culture.
Users find current age verification intrusive, exposing personal data to third parties. PrivAge offers a privacy‑first, zero‑knowledge age verification and authorization layer that lets services confirm age without revealing identity, preserving user data ownership.
Designers struggle with clunky rectangle selects and manipulation in both photo editors and CAD suites, causing wasted time and frustration. SnapSelect offers an AI‑driven, cross‑platform selection layer that replaces drag‑and‑drop with gesture‑based, context‑aware selection, dramatically simplifying workflow in both 2D and 3D design environments.
