WhatFont 4+

Hello, awesome plug-in, but I've found that some items may flicker on the page load, if your plugin is installed in Safari.

usually it happens, when item has "transform: xxx" property in css. Then it flickers while loading and it happens only with your plug-in on and makes debugging more complex.

Could you make it stop flickering? So much help!

While it’s new to the App Store, I’ve been using WhatFont for a while; it’s great for font geeks like me, designers and developers. When you open WhatFont the first time, it’ll ask you to activate it in Safari preferences; then it’ll install a little button next to the search window on Safari. When you click the button, it activates Whatfont, and when you hover over text on a website, it’ll display an elegant little “tooltip”-style bubble that tells you what font you’re seeing. Then, if you tap/click, a larger window opens that shows you the font family, stack info, style, weight, size, line height and hex number. An “Exit WhatFont” bubble-button sits at the top right of the Safari window, so you can deactivate it and get back to regular viewing as soon as you have your info. Truly helpful, very simple.

Been using it since it was still hosted on GitHub. In the macOS Mojave update Apple shut down all extensions not from the Safari Extensions Gallery, so I'm quite happy it's come back on the App Store!
