    If you use Metamask, make sure to use the official site https://metamask.io/ because there are copycat phishing sites that look very similar. Use your Trezor to manage the private keys & seed phrase, because without a hardware wallet some people have typed seed phrases onto extensions like Metamask and been hacked.

    Tree Style Tab, Show tabs like a tree.

    Project mention: How do I shift the favicons of websites in tree style tab to the right ? | reddit.com/r/firefox | 2021-08-21

    There is no option to just move the favicon over next to the close button. I am not sure you can change something like this via CSS as you basically need to change the DOM structure of a tab. You could consider posting this question over in the TST discussions section to see other people's thoughts. (https://github.com/piroor/treestyletab/discussions)

  • GitHub repo saka-key

    A keyboard interface to the web

    Project mention: Helix: a post-modern text editor | news.ycombinator.com | 2021-06-01

    I'd say that pointing is inherently slow because it involves checking where the cursor is, where the target is, moving it in that direction, then stopping at the right time. With a typical keyboard-based browser interface clicking the update button would have been a 2 combination.

    Check demo animation on Saka Key's readme: https://github.com/lusakasa/saka-key
