Dimensions

I NEVER write reviews for anything, but I've been using this extension since it was first released many years ago and didn't realise just how much I rely on it in my day to day as a FED until it was gone due to this whole manifest clusterfu*k thing. MANY THANKS for updating it! Appreciate!

You're welcome! I only did a small part in that: I pushed the update live. Adriano Valumin (https://github.com/xDhii) did the programming work and submitted a pull request.

It was a great and useful tool until Chrome killed it by revoking its support for the old manifest.

this is the best measurement tool I've ever used - I've been using it for years - it so quick and easy to use - and now Chrome have disabled it - and there's no alternatives that are anywhere as near as good as this

Such an amazing and useful tool for designers. Please add shortcuts to enable and exit.

I use "Option + D" to toggle Dimensions. You can set a shortcut here: chrome://extensions/shortcuts

A tool every frontend engineer should have

This is so simple to use and makes it easy to measure exactly the thing you want. I tried Measuremate and Designer Tools, but they were buggy and confusing to use. (They make it hard to measure a particular thing; you just click randomly and pray. They also don't play nicely with the responsive view of dev tools.) Dimensions is perfect. Plus, this extension apparently doesn't collect or sell data. 5/5.

Thanks for the kind words. Yes, the extension doesn't collect any data. It can't access your surfing data because it's only getting information about the website your on when you enable it to measure.

very useful

A very useful tool. Works great even on macOS.
