So... where is the crowdfunding to get webextensions working with WebKit GTK? (not asking for a friend)

I mean, I know giving to Gnome is already a good way to help it happen some day, but I'm wondering if there is something more specific already in the making. For instance is there someone who said they'd be interested in doing it but don't have the funding, or a specific intent statement from the Gnome foundation?

Hey @delta! Reading this https://delta.chat/en/2025-05-22-browser-edition got me thinking. I live in Firefox but miss Chrome’s one-click “Install PWA as app”. What about a Tauri-based helper + a Firefox extension that wraps a PWA into a desktop app in one step? Hosting stays light: the PWA is cached; relays/self-hosted instances can serve the client. Keeps control with admins. Interested? 👍🏻

edit 2026-03-26: actually, after some discussion in the comments, i have been using this extension for quite some time after all and it's become essential for me

edit 2025-10-08: i cannot vouch for the extension i linked and no longer recommend it. when i extract it and look at its background.js, there's a lot of stuff that i can't explain and i am not comfortable with. sigh... but it seems like a good concept.

one of the things that concerns me about private windows / incognito windows is that you only get one session at a time. this is a downgrade from the isolation that firefox-based browsers offer you with container tabs, especially if you have a tracker-licious website open alongside something else in your private session.

Temporary Containers Plus is an interesting idea - with Automatic Mode, you get a new container per tab: https://addons.mozilla.org/en-US/firefox/addon/temporary-containers-plus

came across a nice browser add-on that disables the generation of AI overviews in search engines like duckduckgo: https://addons.mozilla.org/en-US/firefox/addon/disable-ai/

super useful if you don't keep site data across sessions or if you mostly browse in private windows.

for firefox / librewolf / whatever.

What the fucking fuck that #Chrome doesn't support `background.scripts` in its Manifest v3 for #WebExtensions.

That is stupid.

If you wanna know why I haven't released BlogCat for Google Chrome and by consequence for Vivaldi, Edge and the other Chromiums, it is because of that.

I will also be grateful if you put 👍 a suggestion that will make life easier for developers of userscripts and browser extensions.

Let's not forget that the #web is made for people, not website owners and companies. Browser extensions should help people.

The #Chromium update that drops #WebExtensions v2 is finally here. A sad day for the open Internet.

Ok. Just culled ~20,000 of 25,000 #tumblr posts accumulated via #RSS over a month. I've gotta get to work on my own project applying basic statistics to this stuff. Think "reverse chronological + $all_your_own_filtering_and_sorting_and_bucketing". Not sure if I should do that within the confines of a #thunderbird add-on, or try some other approach. I really, really want to be able to use #sql for this stuff. It's a natural fit. But #sqlite seems to be a no-go for #WebExtensions. There is only #IndexedDB, which, in my limited experience with it, is absolute garbage to work with.

Поддержка webextensions под Андроид, вторая серия

Очень добрый день! Меня зовут Тимур и я программист. Сегодня я хочу продолжить разговор о поддержке расширений браузера (хромиум) на Андроид. В прошлой своей статье я рассказал о том что у меня получилось завести расширения но народ так занят стенаниями по поводу закрытия проекта Kiwi что никто особо на это внимания не обратил, поэтому буду краток, это скорее промежуточный отчет чем анонс.

Just started the work on a new version of my InMyPocket #firefox #addon for #Pocket.

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 🤓

#webextensions #indiehacker

Lots of great #WebExtensions features and fixes just went out with #Safari 18.4 for #macOS 15.4, #iOS 18.4, and #visionOS 2.4 — including new WebKit APIs, temporary installs on macOS, and support for Developer ID–signed apps.

Поддержка webextensions под Андроид

Добрый день! Меня зовут Тимур и я программист. Сегодня я хочу представить очередную свою работу, точнее рабочий черновик. Да, я в курсе — дураку полработы не показывают, но так и на хабре то не дураки сидят. Итак, сегодня я расскажу как перенес поддержку webextensions в chromium под Андроид, что работает а что не работает, как пользоваться тем что работает и когда будет работать то что не работает.

#WebExtensions #malware #browserPerformance

@trentskunk Welp, not surprised.

Vivaldi experiencing, as they put it, "a performance drag" from considering a proper implementation is the probable result of trying to pluck so much stuff in the browser, so they choose a status quo of OBEDIENTLY following Google's version of the Manifest V3 spec. How come they don't take a page from Firefox that keeps both Manifest V2 and V3 that doesn't impede extensions' capabilities as much as Chromium?

I give $AAPL a lot of shit, but I'll admit that it's good to have their skin in the game adding support for #ContentBlockers and #WebExtensions.

I'm updating my no_downvote_display extension to add support for Manifest v3 since I figure it's worthwhile to do so because downvotes can be bad mentally even with Google's anti-adblock thing. Officially I don't support Google Chrome or Chromium, but I do support #Vivaldi if you need a Chromium-based browser. Preferably I'd say to use Firefox if you can, though.
