Memory leak may have been a misdiagnosis. The issue is clearly with Youtube, which is what most extensions I use are about, there is nothing obvious in the memory snapshot (not that it’d be easy to see, because video is a resource hog anyway) and the profiler seems to label the stutter with the very useful label of “jank”, so…
Someone more familiar with web dev than I am may be able to take the profiler logs and debug this, but a) that’s not me, and b) not my job.
Jank means that the renderer was delayed due to a resource conflict - usually because there’s something on the main thread that’s taking too long. Basically your issue is probably a CPU (or GPU) one, not a RAM one - It’s hard to help you out without knowing more about your environment, so all I can really give you is vague advice: if you’re using an adblocker other than uBlock Origin, switch to uBlock Origin, it has much better performance. Check the plugins and extensions and make sure there isn’t something you don’t recognise, if your computer was compromised at some point, cryptominer plugins can really tank performance.
Figured that much. I’m not a web developer, but I can read a profiler, and the CPU usage spikes before those gaps are a pretty good sign that this isn’t a memory leak. I use uBlock Origin, by the way, but there’s likely some weird interaction between it, other Youtube extensions and Youtube’s own attempts to nuke adblockers from orbit. And no, it’s not a cryptominer as far as I can tell. This looks like either a bug or an unintended behavior of the very popular, very sanctioned plugins running on Firefox (or Firefox itself).
Which is why, as I said, I have settled for periodic reboots. Convenience wins over principle often, but I happen to be stubborn.
Gotta say, though, I appreciate the attempts at troubleshooting, but the OSS and privacy communities in general have a tendency to respond to comments on poor performance, compatibility or UX with tech support, and I think it’s kinda missing the point.
Once it’s slower, hit F12 -> memory -> snapshot
Should be pretty easy to check out which extension has shitloads of storage. Then you can decide how to go from there - maybe contact the author?
