It’s been over a year since we last posted about the current state of Lightning usage. Since that day Thunderbird 5, 6, 7 and 8 have been released with their Lightning counterparts 1.0 beta4, 1.0 beta 5, 1.0 beta7 and finally Lightning 1.0.
Now it’s time to look at things again and I’m happy to report, that Lightning is more popular as ever before with nearly 30% more daily users than one year before. Right now we average nearly 1,400,000 users each day during the workweek and about 775,000 users on the weekends, which brings to more than 1,200,000 users on average over the course of a week.
Most of our users (64.2%) are now on Thunderbird 8. Most of the rest still uses Thunderbird 3.1 (15.0%) and Thunderbird 7 (13.4%). The remainder (7.4%) is mostly distributed to Thunderbird 2 (still at 2.3%), Thunderbird 6 (2.6%), Thunderbird 5 (1.0%) and other installations (other Thunderbird releases, SeaMonkey and Firefox) at 1.5%.
