Safely use sensitive data with online tools
We have our first bug bounty!
Thank you "dz2742" for finding out  existing connections including websockets are not terminated and has won 100 USD! This is exactly the type of exploit I was hoping to catch.

Style and Grammar Checker for 25+ Languages
On extensions, for example, I use LanguageTool , which is similar to Grammarly. It could be configured with a local server, although I have a “premium” account which sends data to a 3rd party server. I trust this extension to verify my messages on HN, but I can't trust it to have access to my banking account. This is an example of a really useful extension that I'll never be able to fully trust because it has access to all websites, and it sends all that I write to another server.
In fairness, Firefox's advantage has been that Mozilla has a trustworthy manual review process for the “recommended” extensions.
Lets try this again. Got a code for you to break.
