Will need to take a look - if I'm lucky, maybe some firmware is now needed. If not, the joys of finding an easily reproduceable test case: perhaps the time to untar firefox from nfs, followed by finding a "good" kernel (and I suspect this goes back some time). At the moment I don't think I've seen the problem on other machines, but I suppose I ought to check in case it is something on the server that is the problem. Objectively, less important for the general user than the libssh2/vlc problem - so I'll concentrate on that. ĸen -- It is said that there are two great unsolved problems in computer science: naming, cache invalidation, and off-by-one errors. -- Ben Bullock -- http://lists.linuxfromscratch.org/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page

Just testing firefox 66.0 with alsa and kernel 4.19.30 on a Dell Latitude E7240 and experiencing absolutely no performance issues, as I type this mail into thunderbird 60.6.0. I gues my problem was somehow kernel/disk related.

The machine seem to be not much better off, so, it seems to be totally unrelated. As I type this mail, the box randomly hangs for seconds while typing. I'm sure this is recent, otherwise, I would have gone mad by now. Will check a few other things now. Just to inform you. I now upgraded my kernel to 4.19.30, rebooted the machine and now all seems well. So in short. firefox 66.0 seems to work well with alsa and youtube, no issues here.
