I find that firefox 105 or 107 are almost unusable on a laptop running NetBSD 10.0 BETA.

But on Linux I can use the same laptop with firefox 107 without any problems. [ I have yet another laptop with 2G RAM, on which also firefox works fine on Linux. On yet another laptop with 8G RAM, with amdgpu, on NetBSD 10 BETA, firefox simply crashes sometimes taking down the OS. (PR already logged). ] Can the difference have something to do with drm not working properly on NetBSD. (There is a different thread "i915 observations" on these issues. Linux uses SNA acceleration which is somehow not working on NetBSD.) On the other hand, wonder why firefox has to start so many processes and occupy so much of RAM in the first place. This is just a pristine installation without any extensions or plugins and top snapshot when nothing is opened in the browser as yet - just a single and blank tab. And are there ways to trim its memory and CPU footprint, at compilation time or using config or CLI options? -- Mayuresh
