Well, on desktop it worked. So you could do it that way. But on mobile, what you had to do was go to a website like Google, add it as a bookmark, and then edit the bookmark and change the web address from Google to the IPv6 address.

Probably because most people are not accessing routers and web servers through their IPv6 addresses and instead they are using IPv4s like 192.168.1.1. I mean, come on, who does that?

That patch was my only contribution to Firefox, and I didn't research how to update the user-facing changelog. When 122 hits my phone I'll ping the bugs, to notify the 20 nerds who actually care about the problem. Typing IPv4/IPv6 literals is a pretty niche feature on the modern web.

Currently https://play.google.com/store/apps/details?id=org.mozilla.firefox says "Version 121.1.0, Updated on Jan 19, 2024"

It's not in the linked article, but it was part of it in the beta release notes. Now it's on the dedicated Android release notes page (https://www.mozilla.org/en-US/firefox/android/122.0/releasenotes/):

• Firefox for Android can now be set as the default PDF reader.
• Firefox for Android now supports enabling Global Privacy Control. With this feature, Firefox informs websites that the user doesn’t want their data to be shared or sold. This feature is enabled by default in private browsing mode and can be enabled in normal browsing in Settings → Enhanced Tracking Protection -> Tell websites not to share & sell data toggle.
• To reduce user fingerprinting information and the risk of some website compatibility issues, the OS version is now always reported as "Android 10" in Firefox for Android's User-Agent string.

There's a link at the top: https://www.mozilla.org/en-US/firefox/android/122.0/releasenotes/.

Not sure why that's a new thing. I've been using Mozilla's PPA since canonical introduced this snap-by-default crap back in 22 I think.

How do I log a bug?
