4. Web Developer

The web developer extension for Chrome adds a little toolbar with different tools available. The original concept of this Chrome extension for developers came from the PNH Developer Toolbar.
The chrome extension web developers has a lot of handy tools a developer can use in their day-to-day work – for designers as well as programmers. It allows you to do a lot of more then the standard Chrome Inspector, like being able to easily add outlines to elements just by clicking, displaying rulers, finding all broken images on a page, and lots more.

5. ColorPick Eyedropper

An eye-dropper & color-picker tool that allows you to select color values from webpages.
If you feel the need to alert the developer about a bug use the feedback forum instead of writing a review.

If you are having problems with accuracy use the arrow keys, and enter to pick colors once you get the mouse in the approximate location.

Please note that colors are picked from a snapshot of the page that is updated only when you scroll. To take a new snapshot press r or use the re-snap button. Sometimes if you just changed tabs, you may see a snapshot error - this is an intentional security feature. Press R or scroll to correct this, or exit color pick and try again.

I am a developer and in addition to some of the above, I use the following

  • AdBlockerPlus & uBlock Origin
  • Google Calendar because I time-block myself and want to be notified on computer and phone
  • LastPass, I assume every dev should be using some sort of password manager
  • Web Server for Chrome for quick testing
  • ColorZilla
  • JsonFormatter
  • Postman & Interceptor
  • Google Docs

AdBlockerPlus & uBlock Origin

why don't you just pick the latter?

WHOA! I hadn't heard of any of these... It amazes me what's out there that "every developer" knows about, but clearly there's a ton of room for sharing knowledge still. 😉 Thanks for the list!

So everyone can take that as a lesson: it doesn't matter how obvious you think something is - you can still share it! Someone out there hasn't heard it before :)

Ghostery is a great tool. But once you install it, you'll start getting pissed off, seeing what every website tracks.

uMatrix gives a nice breakdown of how nice a website is

It becomes really hard not to ask myself 'wtf is all this crap'

Here's a couple extensions for devs that I have developed, and open sourced at github too:

Quick source viewer, to quickly see the HTML, CSS, JS of a page:

Page size inspector, to quickly report the total page size, number of requests, cache use:

I'll throw mine into the mix.

It's a super simple "Cookie Crusher" that clears all the cookies on the current site and reloads the page in one click:

I would replace the following:

Also, there is an extension slightly similar to Wappalyzer, but for a WordPress site analysis: WordPress Theme Detector and Plugin Detector.

Awesome list Jay!

I use the Dark Mode, JSON View, ColorPick Eyedropper, and Page Ruler. Apart from these, I use:

  • Adblock Plus
  • Dashlane
  • Daily (New Tab Extension)

I wonder what do you use as your new tab extension, and why not an adblocker?

Usually, I tend to not promote OctoLinker myself in comments, but it's essential for every GitHub user 😉

I'd recommend GhostText - a great extension that allows you to sync a textarea on a webpage with your IDE.

You should really check out

I don't really see the benefit of a colour picker. For development its more effective to use the debugger to alter the page and pick a colour.
