Does anyone have this issue were firefox becomes slow if left open for a long time. In my case after a couple of weeks rendering becomes slow and when I use youtube for example if is laggy, just trying to change volume taka few second to show the volume bar. It also happens to my laptop at work. I have around 30 tabs open.
Most software in general has hard to detect issues after several weeks of uptime. Its something that’s fundamentally hard to test and fix. Its a big reason why “did you turn it off and on again” is such universal advice.
Even if the software was perfect, virtually all desktop RAM isn’t ECC equipped, so you potentially have even the hardware corrupting the state and requiring restarting because of that.
