I'm trying to use both Firefox Quantum 68.10.0 ESR 64-bit and TOR browser 9.5.1 (= based on said Firefox 68.10.0 ESR) on a Linux Mint Debian Edition 4 machine. What's with the resources squander of these browsers?
Both show up in gnome-system-monitor
with several processes, for Firefox Quantum it's
firefox.real
Web Content
WebExtensions
and for TOR browser it's
firefox-bin
Web Content
WebExtensions
The culprits are the two main processes, firefox.real
and firefox-bin
(one per instance), and the process Web Content
(up to several per instance). Just running a YouTube video or surfing around causes CPU load to spike to 40-60% and RAM usage to 600-900 MB, with the latter usually not decreasing by itself anywhere fast enough. To make matters worse, the audio in all YouTube videos is extremely choppy, i.e. there is a high-frequency "glitching/crackling" that directly modulates with the volume (if someone speaks up, the crackling gets worse).
What's the matter with Firefox these days? Just 10 years ago, this would have simply and inevitably crashed/freezed any normal PC - as a matter of fact: Both do tend to freeze-crash any live Linux system running on USB 3.0 flash drives or external SSDs with high reliability, which is why I cannot use them on live systems.
How can a mundane web browser demand this much resources and underperform compared to literally any of its competitors? It feels like looking after a badly spoiled, hyper-entitled brat - and it's both Firefox and TOR browser which are affected, so clearly this is an underlying Firefox issue. Disabling all extensions, disabling Javascript, and resetting all settings is not helping, neither is purging and reinstalling. Plus, I'm positive that more people are experiencing exactly the same issues as anyone can easily tell from a quick web search - but Mozilla so far has not been able or willing to present working solutions. If I'm wrong with this statement, I would be glad to be pointed towards the right source!
What exactly is causing this abnormal behaviour? Are there any diagnostics that one could run?
I'm happy for any suggestions and will provide any information requested. Furthermore, this topic will be up for bounty shortly. Looking forward to your ideas!
