Firefox 101 is out, this time with no 0-day scares (but update anyway!)
2022-06-01 14:31

This follows an intriguing month of Firefox 100 releases, with Firefox 100.0 arriving, as did Chromium 100 a month or so before it, without any trouble caused by the shift from a two-digit to a three-digit version number. No doubt in part due to the efforts of both Google's Chromium and Mozilla's Firefox coders, the 100.0 release of both browsers was ultimately uneventful.

Firefox out-of-band update to 100.0.1 – just in time for Pwn2Own?

Late last week, our Slackware Linux distro announced an update to follow the scheduled-and-expected Firefox 100 release, which came out at the start of the month. The blog article, entitled Improved Process Isolation in Firefox 100, actually came out the day before the 100.0.1 release was uploaded to the FTP server, as though the changes were already accomplished in the 100.0 release.

Firefox hits 100*, fixes bugs… but no new zero-days this month
2022-05-03 18:42

At its current release rate of once every four weeks, Firefox has just over 23 years to go to equal Lara's quadruple century, and almost 30 years to reach 502*. No trouble at the version number mill. Back in February 2022, a few mainstream sites didn't seem to realise that 100 was greater than 99, presumably because they were hard-coded to use only the first two characters of the version number, millennium bug style, thus turning the text 100 either into the number 10, or into the number zero.

Firefox 99 is out – no major bugs, but update anyway!
2022-04-05 20:21

The once-every-four-weeks security update to Mozilla's Firefox browser officially arrived today. The regular version of Firefox is now 99.0, while the Extended Support Release, which gets security fixes without any feature updates, is now 91.8.0 ESR. Add together the first two numbers in the ESR release triplet and you should get the same value as the first number in the regular release.
