  • GitHub repo Surfingkeys

    Map your keys for web surfing, expand your browser with javascript and keyboard.

    Project mention: Vimium | | 2021-11-27

    I read several comparison articles and a lot of people seem to settle on Surfing Keys. I'm pretty happy with it although there's probably more default key bindings than you'll ever use and I find across these extensions the keymappings aren't as intuitive as in VIM... but of course, you can always customise them and make your own!

  • GitHub repo treestyletab

    Tree Style Tab, Show tabs like a tree.

    Project mention: Ask HN: What browser extensions are a must-have for HNers in 2021? | | 2021-11-22

    Also on Firefox. It appears that I'm not as privacy/security conscious as are most in this thread, but I heartily second HTTPS Everywhere.

    However, the single Firefox extension that's indispensable to me is Tree Style Tabs. See:

    Is it possible (for a Web page hoarder like me) to organize and access 500+ tabs across seven Firefox windows? You betcha it is, with Tree Style Tabs.

  • GitHub repo user.js

    user.js -- Firefox configuration hardening (by pyllyukko)

    Project mention: Don't you feel that Firefox is now father than Chromium ? | | 2021-11-25
  • GitHub repo multi-account-containers

    Firefox Multi-Account Containers lets you keep parts of your online life separated into color-coded tabs that preserve your privacy. Cookies are separated by container, allowing you to use the web with multiple identities or accounts simultaneously.

    Project mention: Multi-Account Containers to “Exchange messages with programs other than Firefox” | | 2021-11-25

    There's no obvious reason to grant the nativeMessaging permission during extension installation, nativeMessaging can be declared as an optional permission since Firefox 87 [1], and Firefox Multi-Account Containers 8.0.2 only supports Firefox 91 or newer.

    There could be a bug related to declaring nativeMessaging as an optional permission, though that is not mentioned in the pull request [2], so this was probably a mistake or oversight.

    A neutral new tab page accented with a chosen colour. Customise the layout, style, background and bookmarks with nightTab.

    Project mention: Any good new tab extension recommendations? | | 2021-11-25

    I use what I like about it is you can customise pretty much anything but if your lazy you can keep it simple too. If you scroll down the github you can see a bunch of ways you can customise it.
