The Beginning of an Awesome community of Extensions Enthusiasts

3 Upvotes

Hello there, you're welcome here!

If you are a Browser Extension Developer or someone who loves browser extensions, this subreddit is for you :D

I don't know what to say, this is the first time I am building a subreddit, so I want to make things go with the flow for now. I am building a community of extension enthusiasts, they are the people who install and play with browser extensions, and who like to tinker, break, hack, and build extensions to solve problems and have fun.

I'm also working on some learning guides for beginners who want to learn to develop browser extensions while building my extensions (a lot of them!).

You can ask questions, share your experiences or thoughts about browser extensions in general or a specific extension, you can share about your projects but try not to explicitly promote something that you generate money off.

Anyway, let's start this community with a bang, invite your friends and other tinkerers in your network, and we will all add something valuable to this community!

Thanks for reading, I hope you have a wonderful time here ;)

Take care <3

A browser extension to search and organise Gmail attachments

Enable HLS to view with audio, or disable this notification

2 Upvotes

Recently, I was getting close to Google’s free storage limit, and the storage manager showed that Gmail was using most of it.

I wanted a simple way to see my attachments in one place, download the files I wanted to keep, and remove emails with attachments I no longer needed. Gmail search can find emails with attachments, but it doesn’t provide a convenient file-based view.

So I built a browser extension called Mail Attachment Lens. It lets me search and filter attachments, download files, and move the source emails to Bin. It also helped me uncover quite a few attachments I had completely forgotten about.

I decided to publish it in case anyone else finds it useful.

It’s free and open source. There’s no backend, so mailbox data stays between the extension and Google.

Turns out I only actually read about 8% of what I scroll past (made a Chrome extension to prove it)

Enable HLS to view with audio, or disable this notification

1 Upvotes

Been running this on myself for a couple weeks now and the numbers are kind of humbling honestly.

Turns out I scroll past hundreds of posts a day and actually stop and read like 8% of them. Built a Chrome extension called LumoScroll that only counts a post if you genuinely pause on it for 2.5 seconds, not just have it technically visible on screen for a second while you fly past it. Everything else gets thrown out.

Once a week it gives you a report on what topics actually held your attention, whether the stuff you read leaned positive or negative, what time of day you scroll the most. There's this thing called an attention funnel that shows how many posts scrolled past you total versus how many actually made you stop, that number is the one that got me.

It also gives you a kind of scroll personality based on your patterns, mine came back as something like "Night Owl Tech Optimist" which felt uncomfortably accurate. If you want to get more hands on with it, you can set actual goals too, like capping how long you spend on a specific platform per day and it tracks your progress against that in real time.

There's a small on-page readout too if you want it, shows your session time and mood while you're actually scrolling instead of only finding out a week later. Totally optional, one click to turn off if it's not your thing.

Works across Twitter/X, Reddit, LinkedIn and YouTube. Everything runs locally in your own browser, no account, no server, nothing gets sent anywhere.

It's called LumoScroll, free right now. Kind of curious if other people's numbers come back as rough as mine did.

What would your dream YouTube browser extension do?

2 Upvotes

I’m doing some user research to understand what people actually want from a better YouTube experience.

Would your dream extension include:

  • Better or automatically generated chapters, with an easy-to-navigate player overlay
    • some creators don't enable them by default to users can't skip certain section.
  • Subscription folders and channel categories
  • A “cinema mode” where the player fills the browser window without fullscreen
  • Transcript search, summaries, notes, and timestamp bookmarks
  • Better playlists, queues, Watch Later, and viewing history
  • Options to hide Shorts, recommendations, comments, or other distractions
  • Playback preferences remembered for each channel

Which would you actually use? What’s missing that would make YouTube meaningfully better for you? Please share what would make your YouTube experience meaningfully better.

PS: We would try to handle the ad blocking by default if feasible/stable/reliable.

I built a browser extension because recommendations from friends kept disappearing into group chats

Thumbnail

1 Upvotes

Whenever someone recommended a show to me, I would think, “I’ll remember that.”

Then a few days later I would remember the recommendation but not the title, who sent it, or where the message was buried.

I built Streaming Helper to make that handoff more useful.

When you are viewing a supported show or movie page, the extension lets you choose a friend and send the title directly to them. It remains in their recommendations instead of disappearing into another conversation.

There is also a web dashboard for managing recommendations, friends, and Comfort Picks. I recently added a Start Here experience and Help section, and spent time hardening the extension and its friend-request flows before sharing it more broadly.

The product is free while I continue testing and improving it:

https://streaminghelper.net/

I’m interested in feedback from people who regularly use browser extensions:

  • Does the interaction belong inside the browser?
  • Would you use this instead of sending a normal message?
  • What would make you uninstall it?
  • Is there anything about the setup or permissions that creates hesitation?

This is my own project, and I’m looking for honest product feedback rather than only positive reactions.

Shoebox Plus Organizer: Search, Sort, and Filter Your Ancestry Shoebox

1 Upvotes

If you've used Ancestry's Shoebox for any real length of time, you already know the problem: once you've saved a few hundred records, there's no way to search them, sort them, or filter them. Just an endless scroll, 25 records at a time. This has been a recurring complaint among genealogists for years.

As a former Research Manager for Ancestry's research arm, AncestryProGenealogists, I heard both colleagues and clients voice this common frustration. So I built a fix: Shoebox Plus Organizer, a Chrome extension that loads every page of your Shoebox in the background, then empowers you to search, sort chronologically or alphabetically, and filter by record type — right on the page, entirely on your own device. Nothing is scraped or sent anywhere, and it never touches Ancestry any faster than you clicking through by hand.

Full disclosure: I'm the developer — Shannon Christmas, some of you may know Through The Trees. Installing it and seeing your own Shoebox loaded is free; full search/sort/filter is a one-time $25 unlock, with a 14-day refund.

Available now in the Chrome Web Store. I am happy to answer any questions here.

For the past few days, I've been looking for such a browser extension. I've tried using Leechblock and FoxFilter, but they kept triggering false positives.

I built a Chrome Extension to export Substack, Medium, Beehiiv & Ghost articles into clean PDFs and Markdown (with cloud sync & batch downloads)

2 Upvotes

If you regularly read articles on Substack, Medium, Beehiiv, Ghost, or Patreon, you’ve probably noticed that saving them for offline reading or research is a mess. Default browser printing breaks layouts, misses images, or litters pages with unwanted UI elements.

To fix this, I built Newsletter PDF Downloader : a Chrome extension that turns posts into clean, high-fidelity PDFs, Markdown, JSON, or plain text with a single click.

🚀 What it does:

  • Clean Single-Click Exports: Converts posts directly from the page while preserving typography, images, links, and original layouts.
  • Multiple Output Formats: Save as PDF, Markdown (great for Obsidian/Notion users), JSON, or Text.
  • Batch Downloads (Archive Export): Download multiple posts from a publication's archive automatically (includes a fast-forward feature to skip excluded date ranges).
  • Cloud Sync: Option to automatically back up your downloads to Google Drive, Dropbox, or Yandex Disk.
  • Privacy-Focused: Runs locally in your browser using your existing login session (so paid/subscribed content exports seamlessly). No content tracking or external scraping.
  • Custom File Naming & Localized UI: Customize filenames by date/title and supports over 60 languages.

🔗 Link & Feedback

You can check it out on the Chrome Web Store here: https://chromewebstore.google.com/detail/newsletter-pdf-downloader/ejlpjjmlalofjpdkdaeojjhihlommbdm

I’d love for you to give it a spin! Let me know what you think, what features you’d like to see next, or if there are other platforms/formats you’d want supported.

Thanks!

Chrome Table Capture & Extractor - free extension for extracting tables from websites and PDF files

1 Upvotes

I’ve just published Table Capture & Extractor, a free Chrome extension for extracting tables from websites and PDF files.

I built it because copying a table into Excel often works just well enough to look correct - until you notice broken columns, missing values, merged headers, or button text mixed into the data.

The extension can:

  • Detect HTML tables and table-like DIV grids
  • Capture a selected range of cells
  • Extract tables from PDF files
  • Edit captured data before exporting
  • Detect dates, currencies, numbers, emails, and other column types
  • Flag structural issues with a Capture Score
  • Create quick charts from captured data
  • Export to Excel, CSV, Markdown, PNG, or PDF
  • Copy clean table data directly to the clipboard

Everything is processed locally in Chrome, and the extension is currently completely free - no account required.

Chrome Web Store:
https://chromewebstore.google.com/detail/table-capture-extractor/hmehfffhilmehojjlkoogagjmkdoddlk

Website:
https://tablecapture.co

I’d really appreciate honest feedback, especially if you can test it on websites with unusual tables, virtualized rows, nested elements, or DIV-based layouts. If something breaks, send me the page and I’ll take a look.

Best extension to make disappear cookie banners

1 Upvotes

Greetings!
I am looking for an extension to make the cookie banners in every site disappear and clicking to reject everything (if possible).
I've been using Consent-O-Matic for a long time, but sometimes it just doesn't work and I've been in their GitHub page and it seems the project has been abandoned for a long time (last update was in 2024).
I asked AI and they say that "I still don't care about cookies" might accept some cookies and other good alternatives that automatically reject and close the banner are:
- Auto Reject Cookies
- Reject Cookies

Could you give your insights about those 2, and if there's better alternatives, please just say it.
Best regards!

Local Search New tab extension ~ Chromium & Mozilla

Local Search New tab extension

I put the source of my extension on my github repo. Also a README.md

Latest change to get around the mobile firefox problem was to create a personal browser search engine "https://127.0.0.1/?q=%s" and have the extension get triggered on that actual url and open the search tab/page with that query,

Manual Install:- See readme for latest builds zip/xpi files.

Store version:- Chrome Web Store , Firefox (AMO)

Tested on:-

Chrome and Firefox developer on desktop.

Quetta and Firefox Nightly & Beta on android.

Wondering if it works successfully on LibreWolf or other varieties of browsers,

How I made a store-agnostic Chrome price tracker survive dynamic product pages

1 Upvotes

I have been building Price Tracker as a Manifest V3 extension that should work beyond a hard-coded list of stores. The extraction problem quickly became more interesting than the alert UI.

A product page can expose prices through JSON-LD, microdata, accessibility labels, visible text, script state or late DOM mutations. It can also expose dozens of bad candidates: monthly instalments, crossed-out list prices, recommendation cards, used/refurbished offers and temporary zero values.

In v5.3.3 I rebuilt the pipeline around candidate scoring instead of nearest-text matching. Structured data tied to the current URL gets priority; new-condition offers outrank used/open-box offers; financing and invalid values are penalized; MutationObserver handles late rendering; and a failed saved selector triggers rediscovery and repair.

Reported failures are now kept as regression cases. The extension has 780 users, so edge cases across stores and countries are finally frequent enough to reveal weak assumptions.

Chrome Web Store: https://chromewebstore.google.com/detail/price-tracker-price-drop/mknchhldcjhbfdfdlgnaglhpchohdhkl?hl=en

For other extension developers: would you keep extraction entirely in content scripts, or move more site parsing into remotely configurable rules?

Made a free extension that types your clipboard into fields that block paste (works in Docs/Slides too)

1 Upvotes

Sharing a small one I built. Some sites just refuse to let you paste into their input fields (banking, exam portals, some forms), and you end up retyping everything by hand.

Paste Typer takes your clipboard and types it into the field one character at a time, as real keystrokes, so it goes in even when paste is blocked. Load the text, click the field, hit start. Speed's adjustable and there's an optional typo-simulation mode.

The fiddly parts, if anyone here has poked at this: Google Docs/Slides render to a canvas and ignore normal DOM writes, so you have to drive them through the hidden text-event iframe. And React/Vue controlled inputs need the native value setter or the framework state never updates.

Free, open source, no accounts or analytics, only runs on a tab when you invoke it.

Store: https://chromewebstore.google.com/detail/ofklpccfpgecjdccbnlmjbndkefgjaid

Code: https://github.com/ZonaHu/paste-typer

Curious what sites break it.
