Extensions Goodlib - An extension that opens any Goodreads book on Anna's Archive, Z-Library & more in one click.

31 Upvotes

"Open Books in Zlib Or Anna's Archive with a button on Goodreads in one click."

Hello i have been working on this Open Source extension (Source code ,available on Github)

I built a free, open source browser extension that adds buttons directly onto Goodreads book pages. Instead of copying titles and searching manually, you just click the badge for whichever source you want.

You can also toggle sources on/off
so say if you only want Z-Lib and Anna's Archive badges and not Gutenberg, you can do exactly that.

Supported sources:

  • Anna's Archive

  • Z-Library

  • Project Gutenberg

Planning to add more sources based on feedback.

it is available on :

-chrome

-firefox

Available on Chrome and Firefox.
Also for firefox mobile

Anime.js used for animation

No data collected , you can verify that yourself via the source code on GitHub or the privacy page.

Extensions I built a Firefox add-on that changes the browser identity websites see

Thumbnail

27 Upvotes

Websites can read more than your IP, including your user agent, language, timezone, screen size, and device properties.

I built Spoof Me to let Firefox users switch these signals together as one browser identity.

It includes ready-made profiles, custom profiles, and a warning badge when a website accesses fingerprint-related properties.

It does not change your IP address or promise complete anonymity. The add-on does not collect browsing data and is MIT licensed.

Firefox Add-ons:

https://addons.mozilla.org/en-GB/firefox/addon/spoof-me/

Project website:
https://spoof-me.com/

I’d appreciate feedback on the profile consistency, permission explanations, and any fingerprint signals that should be added.

Extensions I built a minimal new tab extension to organize sites by folders and projects

Post image
24 Upvotes

Hey everyone,
I built a Firefox extension called Minimal New Tab.

I originally made it for myself because I wanted a simple place to keep the sites I use every day, organized by folders and projects. Most new tab extensions I tried had too many widgets, so I wanted something calmer and more focused.

You can:
- save and reorder favorite sites;
- organize them into folders;
- customize the background and overlay;
- use keyboard shortcuts to add sites, create folders, and open settings;
- sync lightweight settings between Chrome/Firefox installations;
- export and import your setup when moving to another browser.

I didn’t originally plan to publish it, but I thought it might be useful to other people who organize their work or projects in a similar way.

I’d appreciate any feedback, especially on what could be improved without turning it into another overloaded dashboard.

I made a Firefox extension that lets you view Reddit NSFW/sensitive content without logging in NSFW

Thumbnail
addons.mozilla.org
23 Upvotes

Hey folks,

I recently built a simple Firefox add-on for Android called Be Anonymous. It helps you browse Reddit—especially NSFW or sensitive content—without being forced to log in or deal with blurred posts, popups, or constant redirects.

🔹 How it works:

It redirects Reddit to the old layout (old.reddit.com) where sensitive content isn't blocked behind login walls.

Just tap the extension icon and Reddit will switch layouts instantly—no settings, no hassle.

Works great on Firefox for Android and supports one-click toggling.

I made it mainly for people like me who just want to browse freely without creating an account or being tracked. If that sounds useful to you, feel free to try it out and share feedback!

Would love to hear your thoughts or feature suggestions 🙂

I built a Firefox extension to search inside YouTube playlists — v1.0 submitted!

Post image
21 Upvotes

Have you ever been looking for a specific video in a massive YouTube playlist, only to end up scrolling through hundreds of videos?

That was the problem I wanted to solve.

I built YouTube Playlist Search, a browser extension that lets you search for videos directly inside YouTube playlists.

Instead of manually scrolling through a playlist, you can search for a video by title and navigate through matching results.

After building, testing, and refining the extension, I've finally reached another milestone:

Version 1.0 is out!

I've submitted it to the Firefox Add-ons Store, and it's currently waiting for approval.

The project is open source, and you can check it out here:

🔗 GitHub: https://github.com/migueld51244/youtube-search-playlist

I'd appreciate feedback, especially from people who regularly use large YouTube playlists.

This is one of my first projects that I've taken all the way from an idea to a browser extension submission. I'm looking forward to seeing where it goes next.

Return YouTube Dislike Extension now asking for permission to collect personal data

Is there a reason this extension is now asking for permission to collect personally identifiable information? It doesn't say exactly what information will be collected or how it will be used.

Extensions My Firefox extension just got its first 2 downloads!

Post image
11 Upvotes

A small milestone for a project I've been working on.

I built an extension called YouTube Playlist Searcher because I wanted an easier way to find specific videos inside large YouTube playlists.

It lets you:

  • Search video titles directly inside playlists.

  • Highlight matching results.

  • See how many videos match your search.

  • Navigate between matching videos.

I built it with JavaScript and recently got it approved and published on Mozilla Add-ons.

Today, I checked the developer dashboard and saw the first 2 downloads!

It's a small number, but seeing people download something you built yourself feels different.

I'd appreciate feedback from anyone willing to give it a try.

GitHub: https://github.com/migueld51244/youtube-search-playlist

What would you improve or add?

I just got my first Firefox extension approved! YouTube Playlist Searcher v1.0

Post image
10 Upvotes

Hey everyone!

I've been working on a browser extension called YouTube Playlist Searcher, and it just got approved on the Firefox Add-ons store!

The idea came from a simple annoyance: finding a specific video inside a large YouTube playlist can be a pain.

I built this extension to make that process easier.

This is my first publicly released browser extension, so getting it through Mozilla's submission process is a pretty exciting milestone for me.

You can check it out here:

https://addons.mozilla.org/addon/youtube-playlist-searcher/

I'd genuinely appreciate it if some of you gave it a try.

I'm particularly interested in hearing:

  • Does it work as expected?

  • Did you encounter any bugs?

  • What would you improve?

I'm still learning, and real-world feedback would be extremely useful.

Thanks!

Hey folks,

I’m not super experienced with building extensions, but I wanted to try making something useful to learn from. So I built Fluxboard, It is just a minimal new tab replacement extension for Firefox.

It's just your bookmarks, quick notes, and a simple to-do list. I made it mainly for myself to stay focused and organised, but figured I’d share it here in case anyone finds it useful too.

Firefox Add-on: https://addons.mozilla.org/en-US/firefox/addon/fluxboard/

GitHub: https://github.com/manisharavindh/Fluxboard

Would love any feedback, UI suggestions, code improvements, anything really. If you’re interested in contributing or have ideas, I’d really appreciate it.

Thanks!
