I use Firefox. You should too. It’s fast, secure, and more privacy-focused than the leading browser from the big G.
Yesterday, I got the Calibre newsletter, which always has handy performance-related links from Karolina. She pointed to a Lighthouse extension for Firefox. “Excellent!”, I thought, and I immediately installed it. But I had some qualms about installing a plug-in from Google into a browser from Mozilla, particularly as the plug-in page says:
This is not a Recommended Extension. Make sure you trust it before installing
Well, I gave it a go. It turns out that all it actually does is redirect to the online version of Lighthouse. “Hang on”, I thought. “This could just be a bookmarklet!”

Stuart’s ideas for Lighthouse sound a lot like the resilience validator tool that Scott mentioned recently.
This is our chance to help stamp out sites that don’t do things right, and help define that a progressive web app should actually be progressive.
If you have ideas on this, please file an issue.

This looks like it’s going to be a great evening event. Charlotte and Rosa are both speaking at it, which makes it unmissable in my book.
The very affordable tickets go on sale on Friday, and all the proceeds go to charity.

If you’re already in Brighton for dConstruct this week, there are two art shows you might want to check out:
Timo Arnall and friends are presenting their Immaterials exhibit at Lighthouse, 28 Kensington Street. Timo has written a few words about the exhibit. The exhibition is open from tomorrow, September 5th until October 13th, and the opening is tonight, Wednesday, at 6pm.
Just around the corner at the Ink-d gallery on North Road, the opening of Jon Burgerman’s exhibit is happening at exactly the same time: 6pm this evening. His Failure of Judgement exhibition runs from tomorrow, September 5th to October 6th.
Jon’s opening will also include the debut of the world’s first “Jon Burgerman Veggie Burger” courtesy of Burger Brothers next door.
