Firefox slows after opening many web pages (despite sufficient system resources)

Hey there,

I'm just wondering: Is there a built-in limitation to how well (slowness and responsiveness) firefox can handle a large number (>40) of web pages opened (and used), regardless of system resources?

I'm asking as my system has comfortably enough resources to run firefox with a large number (>40) of web pages opened (barely 5% cpu usage, 14% ram usage, 0% disk usage - I do have a good computer; nothing telling on task manager as to fully utilized system resources), however, I experience (some) slowness and unresponsiveness in this use case. I also feel that firefox slows my whole system down (where if I close it, my system responds better).

Thanks for your advice!

Hi there, for the question, I don't know whether there is a built-in limitation or not. However, I do know that there could be a noticable slowing down if your system is running on traditional HDD as the drive is slower compared to SSD. Besides that, there is also a difference in terms of performance usage between opening 40 tabs of webpages playing videos and 40 tabs of article webpages. So I would like to ask that what type of drive that your system is running on? (HDD or SSD)

My system has an NVME SSD (therefore, disk speed should not be problem). The webpage use is pretty active (ie. resource intensive) however.

If you don't know why its sometimes slow, that's fine. This is a pretty niche problem anyways and only really affects 'heavy' users.
