  1. SingleFile

    Web Extension for saving a faithful copy of a complete web page in a single HTML file

    Project mention: Ask HN: Good Pocket Alternative | news.ycombinator.com | 2025-01-27

    * I really just want pocket as a bookmarking tool than the web reader. The web reader works, but it's very bad in cases with a lot of embeds/code snippets. If a site is pay-walled, only a small section is available in Pocket. I usually open the actual page in this case than read in pocket.

    * Some links I added a long time ago are permanently lost because the original page got taken down. It'd be much better if a permanent snapshot was taken(including all the images, this is pretty easy to do with something like https://github.com/gildas-lormeau/SingleFile) of the page and is available even if the original page is lost.

  12. stylus

    Stylus - Userstyles Manager (by openstyles)

    Project mention: A wonderful coincidence or an expected connection: why π² ≈ g | news.ycombinator.com | 2024-08-10

    Here's a simplified revision of your comment:

    ---

    Totally unrelated to the content, but about the website itself.

    The site completely breaks when I visit it. After some investigation, I found out that if I enable Stylus (a CSS injection extension) with any rules (even my global ones), the site becomes unusable. Since it's built using the React framework, it doesn't just glitch; it completely breaks.

    After submitting a ticket and getting a quick response from the Stylus dev, it turns out that this website (and any site built with caseme.io) will throw an error and break if it detects any node injected into ``.

  16. Reddit-Enhancement-Suite

    Reddit Enhancement Suite

    Project mention: The Return of Digg, a Star of an Earlier Internet Era | news.ycombinator.com | 2025-03-05

    It seems to be OK for me, but I am using https://redditenhancementsuite.com/

    So many that makes a difference. I think it forces the old interface. Like my URL isn't even old.reddit, but all I see is the old interface. Or maybe I don't use subs with newer posts types that are not compatible with old?

    Project mention: Coming Full Circle: It starts and ends with Git and GitHub | dev.to | 2024-12-06

    Browser Extensions: As mentioned in my previous blogs when I worked on the ImprovedTube extension - I have recently been invested in learning more about browser extensions. The work I did for Le Git Graph, has taught me about the complexities of integrating with existing web applications (you have to know a lot about GitHub's interface in order to manipulate it!). Working on this extension made realize GitHub's dynamic nature requires me to carefully handle different page states and navigation patterns - and even then, there might be things that change and I'll have to update the code accordingly.
