I'll let a dev answer that side of things but a couple comments, for what they are worth... 1) The firefox issue is likely related to the sqlite database files it uses. Database random-rewrite-pattern files are always a challenge for cow-based filesystems such as btrfs, tho with small ones like those firefox typically uses, the btrfs autodefrag mount option can help. Be aware, however, that it can trigger performance issues with larger (typically half-gig plus) random-rewrite-pattern files such as VM images and large databases, tho. But if you're not running anything like that and don't have autodefrag in your btrfs mount options, I'd suggest trying it. If you /are/ running VMs and the like, it's worth doing a bit more research on the topic both on the btrfs wiki, and on the backlist, here. There are workaround, but they can get a bit complex... Meanwhile, the problem file is likely in your firefox profile. You could try starting with a clean firefox profile and see if the problem disappears, and if so, bisect the profile to see what file it is and delete it or restore it from backup. 2) Just noting, I'm running kernel 3.19 here without issues, but I run multiple smaller btrfs (largest is <50 GiB) than some people, and I'm on fast SSD, so I don't tend to see the issues that people with TB-sized btrfs on spinning rust see. And I mount with autodefrag... -- Duncan - List replies preferred. No HTML msgs. "Every nonfree program has a lord, a master -- and if you use the program, he is your master."
