  • buster

    Captcha solver extension for humans, available for Chrome, Edge and Firefox

    Project mention: AI bots are now better than humans at decoding CAPTCHAs | | 2023-08-17

    The captcha buster extension[^0] along with the service on you computer to move the mouse for you works very very well. It uses google’s TTS (afaik) to transcribe the audio captcha. It’s google verifying another google service works well. I find it very satisfying to not provide my labor to train googles computer vision corpus but instead have the snake bite it’s own tail.

    Anyway, I highly recommend buster, I barely notice captchas anymore with it.

  • floccus

    :cloud: Sync your bookmarks privately across browsers and devices

    Project mention: Can Chrome Sync or Firefox Sync be trusted with sensitive data? | | 2023-08-29

    There are solutions external to the browsers that work pretty well and where you have control on your data :

    Floccus for bookmarks ( : it works also on mobile devices : a great plus ! You need only a webdav server (or a Nextcloud account), I use Dave (

    Vaultwarden for the passwords (

    A huge advantage of this solution is that you can have synchronization also between different browsers and on mobile devices.

  • markdownload

    A Firefox and Google Chrome extension to clip websites and download them into a readable markdown file.

    Project mention: Ask HN: Should we be saving our favorite information locally? | | 2023-09-22

    Yes and no.

    Instead of PDF, use Markdownload (on iOS, use a Safari web content to markdown file extension):

    And save in a journaled folder like "YYYY-MM-DD - Page" with a YAML frontmatter of all available metadata.

    Have this as a folder in your PKM of choice (Obsidian, Foam, whatever).

    These days, point some text embedding at it, and let it generate your own LLM brain.

    But you can also static-site-generate that back into your own web knowledge site or base.

  • Requestly

    🚀 Most Popular developer tool for frontend developers & QAs to debug web and mobile applications. Redirect URL (Switch Environments), Modify Headers, Mock APIs, Modify Response, Insert Scripts & Record web sessions and share it with your teammates for debugging.

    Project mention: Tell HN: Service Workers === Browser Background Tasks | | 2023-08-29

    If you want to intercept and modify a incoming json response for some specific url pattern, would a service worker be a good way to do so?

    To illustrate, assume I frequently browse and want to trick my browser into thinking that I have "favorited" every post. It's trivial to write a for loop that iterates over response.json and sets `is_favorite = true`. But it's not as clear to me where this script should ideally live in order to have the logic always executed before the response is made available to the site.

    Your comment made me think about whether I can replace my overkill solution ( with something lightweight.
