Fair enough. 7z offers basically the same functionality as winRar including windows shell extensions (right click -> extract here, etc). It has slightly better compression ratios than WinRAR, and it’s open source. It doesn’t nag you to register.

It also supports an insane number of file formats. It will extract files from every pretty much every obscure archive you can think of (.ace, .cab) and all kinds of file types you wouldn’t expect like self-extracting executables, isos, .msi installers, vmdks, and more.

Just use 7zip. It’s so much better.

This is one of the dumbest things I’ve ever read.

Mozilla is a non-profit whose mission is to keep the internet freely available and privacy focused. See https://foundation.mozilla.org/en/who-we-are/

Firefox is built by open source developers who overwhelmingly have those same values. They have also been at this for many years now and have given us no real reason to doubt this commitment.
