Can I use… is an invaluable resource that we all (hopefully) use on a regular basis, but what if you have an existing codebase that you want to evaluate for browser support? You could go through it manually, but that could be a lot of work. Thankfully, someone has put together an app and a Node.js module that can crawl your CSS and list what will break in what browser.
This seems like a useful tool to point users to when you need some information about their browser following an error, to make debugging easier. It also seems to be in active development, so new features will be added over time.
Need a quick way to generate the necessary icons for your site, from the lowly favicon.ico to high resolution icons? I found this really helpful:
No hard decision
With so many platforms and icons, it’s hard to know exactly what you should do. What are the dimensions of favicon.ico? How many Touch icons do I need? RealFaviconGenerator did the reseach and testing for you.
Done in 5 minutes
You spent hours on design, colors, graphics… How much time left for the favicon? Probably not much. But no worries, you only need a few minutes to tackle this task.
Compelling design, a platform at a time
Each platform comes with its own design requirements. You can’t just use the same picture everywhere. RealFaviconGenerator knows this and lets you craft your icons platform per platform.
How will Android display my icon? How will iOS round my Touch icon? No more guesswork. RealFaviconGenerator instantly shows you how your icons will look like.
Firebug caught people’s attention — and more than a million loyal fans still use it today.
So it’s sad that Firebug is now reaching end-of-life in the Firefox browser, with the release of Firefox Quantum (version 57) next month. The good news is that all the capabilities of Firebug are now present in current Firefox Developer Tools.
The story of Firefox and Firebug is synonymous with the rise of the web. We fought the good fight and changed how developers inspect HTML and debug JS in the browser. Firebug ushered in the Web 2.0 era. Today, the work pioneered by the Firebug community over the last 12 years lives on in Firefox Developer Tools.
