Filipe Espósito, writing for 9 to 5 Mac:
As reported now by CNET, Apple and other big tech companies have discussed at the World Wide Web Consortium (W3C) how they can make the process of developing web extensions easier by reducing the differences between web browsers. The idea is that these universal extensions work effortlessly in Safari, Chrome, Firefox, and Edge.
I’m not holding my breath on these efforts bearing fruit on iOS. But as a recent convert to Firefox — on both Mac and iOS — I would really appreciate some improvements to the third-party browser situation on iPhone and iPad.
