Cool extension :)
Super useful for monitoring lazy load images... and great for lazy (sorry "low effort") dev tasks! Colour-coding makes it super easy to see quickly where potential issues are; roll-overs give more detail where needed. Super useful.
Lazy Spy is an impressively simple yet powerful extension that takes the guesswork out of image optimization. It’s an essential, no-nonsense tool for anyone looking to boost site performance without digging through endless lines of code.
Interesantă aplicația, sper să fie bună în continuare.
