Oh Firefox, You Little Resource Hog

I love using Firefox as my primary browser. I prefer using it for a variety of reasons. Lately, though, I’ve noticed that it’s become a bit of a resource hog, and I can’t work out why? I’ve disabled add-ons that I don’t need, and it still uses about 1.4GB of RAM at a minimum for pages that Chrome uses a quarter of RAM for.

Has something changed in Firefox’s architecture? One thought I had is that maybe this has to do with something like page pre-fetching (I think Firefox does that), or something along those lines. I want to sort this out. Chrome seems to be so much better at resource management at the moment.

Update (2018-03-18): Mozilla shared this page to help troubleshoot Firefox memory issues: Firefox uses too much memory (RAM) – How to fix | Firefox Help

    1. I’m using v59 Stable and v60 Developer Edition. It runs pretty well on my MacBook Pro but I noticed it uses 1.3GB Ram minimum. I’ll try a refresh and see if that helps.

    1. Fortunately my work laptop has 16GB of RAM but it would be great not to have to use it all in Firefox.

  1. I don’t like it, I stream and encode video overlays on the fly and need a browser and 1.529 GB is appalling ontop of playing a game. It’s a shame there’s no way to run it in a streamer mode or lightweight mode/profile.
