Pierre-AdrienJust started the work on a new version of my InMyPocket <a href="https://ruby.social/tags/firefox" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#firefox</a> <a href="https://ruby.social/tags/addon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#addon</a> for <a href="https://ruby.social/tags/Pocket" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Pocket</a>. I've already done some behind-the-scenes work lately, now is the time to work on a new release. Not sure how long it will take but it feels good working on the project again 🤓 <a href="https://ruby.social/tags/webextensions" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#webextensions</a> <a href="https://ruby.social/tags/indiehacker" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#indiehacker</a>

𝘋𝘪𝘳𝘬<a href="https://fosstodon.org/@thelinuxcast" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@thelinuxcast</a> Idea idea of browser extensions basing on the <a href="https://gts.0x7be.net/tags/webextensions" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#WebExtensions</a> standard being usable on WebKit is a great promise. I’m looking forward to this – and especially if they go 100% open source with it.

Simeon.__proto__🚨 PSA for folks building <a href="https://toot.cafe/tags/webextensions" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#webextensions</a> 🚨If you're building a Manifest V3 extension, you can have a single manifest.json file that works in all browsers!```json { "name": "Demo", "version": "1.0", "manifest_version": 3, "background": { "scripts": ["bg.js"], "service_worker": "bg.js" } } ```This will use the same background script in all browsers. In Chrome it will load as a service worker while in Firefox and Safari it will load as an event page

Simeon.__proto__I'm a bit behind on hours this week, so I'm going to have to work tomorrow anywayI'm thinking that once I finish out my normal work week I'll work on Background Context, a podcast focused on <a href="https://toot.cafe/tags/webextensions" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#webextensions</a> that I've been thinking about for far too long. I've got two main goals:1. Sort out the tooling I'll use for recording and hosting the show 2. Record an intro episode. Just something to say "Hi! Here's what I'm trying to do. I hope you'll join me on this journey"

Simeon.__proto__Just opened <a href="https://bugzil.la/1907429" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://bugzil.la/1907429</a>. Basically, errors thrown in awaited async event handler never make it to the console's log. It's weird, but it's not nearly as exotic as I originally imagined. I was afraid it was something related to the use of module scripts in MV3 <a href="https://toot.cafe/tags/webextensions" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#webextensions</a> ```js const fn = () => { console.log("Before the error"); // Logged as expected throw new Error("Oh no!"); // Doesn't show up :( } browser.runtime.onInstalled.addListener(async () => { await fn(); }); ```
