It’s a weird pissing contest that still makes people angry for no reason, is what it is.
It’s not the 90s, you’re not trying to parse a bunch of tables on a creaking chunk of barely cooked sand. You’re basically running standalone software through your browser anyway.
Honestly, the one performance thing that bothers me on any modern browser is that some extension in my stack somewhere is memory leaking and makes me restart Firefox to restore performance every few hours. Can’t tell which one, but I need all of them, so hey, frequent reboots it is.
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?
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.
I’m actually having similar issues. Seemingly at random, my PC will freeze up due to lack of memory and killing Firefox fixes it. Im also sure it must be an extension causing it.
Here are my extensions, let me know which of these you are using and maybe we can narrow it down from that:
- Neat URL
- uBlock Origin
- Return YouTube Dislikes
- Firefox Multi-Account Containers
- SponsorBlock
- Vimium
- Decentraleyes
- Enhancer for YouTube
- Privacy Possum
- I don’t care about cookies
- First Party Isolation
- Startpage Privacy Protection
