octomate

adds shiny download button to download files, a TOC, and favorites bar

octomate

octolinkr

octolinker

klim reader

prettier even than Safari which is second prettiest

note to self: you can find stylesheets for extensions the same way as any other (n it might be well-commented too)

feeling lucky

tl;dr guessing / poking around in the dark / deleting everything has never worked and if it has it's infinitely less preferable to the ^ method

feeling lucky is almost always right, if howdoi didn't quite get you there

  1. edit ur search engine settings to include a shortcut to i'm feeling lucky query

  2. mine being l <space> "query"

  3. read the resulting page and weep

my own experiences in debugging (to tears) and watching other developers is the immediate googling of a well-ish worded question will produce the intended result

bonus tip: this is failsafe provided that you've clearly defined distinct steps you need to take & make it happen

double bonus: reading documentation

triple bonus: reading and then practicomg what u read in a sandbox

quadruple bonus: spaced repetition of 1-3

operabrowserjs=no

today in browsing around the file system, i saw this interesting (kinda funny) script whereby opera "pretends its Chrome" for every site from Lufthansa to Australian sports websites to blend.io

simplest example yet mb the most informative of any bookmarklet (second maybe to Axe for accessibility)

javascript: 
  window.location=`
    https://uitest.com/en/check/results/?url=${window.location}
  `

html code sniffer

tests 4 different standards (WCAG2[A]AA, standard 508), with links on how to pass on the relevant whatwg guideline

javascript: (function () {
