24 hr format no matter what? Rated 3 out of 5 stars
I would have posted this on your site but I'd rather not give up my email (which you require).
There is a bug that prevents time from being displayed in a 12 hour format. Even when you are only using the standard formats (all of them being in a variety of 12 hour time) or customizing it so that the time shows up in 12 hour format, every single thing shows up in 24 hour time.
The only way to change it so that it works correctly is to go into about:config and manually modify the appropriate fox clock string. I haven't restarted ff yet so I don't know if it will stick, and if it doesn't that will make this an even more annoying bug. For one, ppl shouldn't have to go into about:config to change a program that used to change the strings when you hit okay or apply - but no longer does - and for two, a lot of ppl won't feel comfortable doing that and will just be stuck with this annoying bug.
I hope this is something that you will fix.
