i'm currently writing my own firefox user.js configuration and now i'm at the topic "unloading inactive tabs" like microsoft edge does.

so what are the preferences for this kind of topic?

i want inactive tabs which have not been used for more than 5 minutes to be unloaded.

chatgpt gave me this "browser.tabs.unloadAfterDelay" preference but this one doesn't even exist in the about:config preferenes, would it still work if it doesn't even exist?

You could look at the following preference in about:config. browser.tabs.min_inactive_duration_before_unload

Try the following settings: 

browser.tabs.unloadOnLowMemory = true
browser.tabs.min_inactive_duration_before_unload = 300000   (5 minutes in milliseconds)
browser.low_commit_space_threshold_mb = 1000000   (1TB arbitrarily large amount of memory)
browser.low_commit_space_threshold_percent = 100  (Linux-only)


The last two "low commit space" values ensures it always detects a low memory state so it immediately triggers tab unloading after the minimum inactive duration has elapsed. This may have a performance hit though, it causes stuttering for me on Linux if it can't get out of the low memory state. It may work better on Windows.
