Hi, IMO this is asking for more trouble than it probably could solve. A browser that is listed as supported, Firefox [3], requires a workaround [2]. It offers an option that "may lead to privilege escalation" [4]. Let alone that I'm sceptic that a quite complicated hack adds "Transparent user experience" [1]. Apart from this I'm allergic against the "Reduced wear to physical drives" argument. I know that some people buy sneakers and instead of wearing the sneakers, they keep them boxed, to reduce wear. I prefer to walk in shoes, to open doors by wearing out handles and I use SSDs without taking care of write cycles. Apart from trimming, I treat them like I treated HDDs and didn't experience SSD lifespans shorter than those of HDD lifespans. My guess is, that the tmpfs approach does offer better performance for some use cases, but it unlikely does affect my usage of Firefox, used to have 2 Wiki tabs opened or similar. I can get rid of hangs by migrating back to 4.19.x kernels and the "intel" driver, which additionally allows me to use Chrome again and would not take extra space from my 3.9G tmpfs (8 GiB RAM). Anyway, thank you again, at least it is interesting to know that this approach does exist. It might be handy in the future, it's just not the right thing for my usage at this moment.
