"Increases the time items will be stored in the browser cache. This increasing the chance that network resources won't need to be fetched. As NVMe/SSD storage is cheap and lightning fast compared to network requests, this has the potential to improve load times significantly".

This extension is very effective to reduce bandwith usage (useful when using tethering, for example). Advice to make it more effective: - Make sure you have disk cache enabled. - You can also increase disk cache size to benefit more (1) - You can check the +6 month expiration date in about:cache?storage=disk (1): If you want to force disk cache to 4 Go, in about:config : browser.cache.disk.smart_size.enabled = false browser.cache.disk.capacity = 4000000 (cache up to 4 Gbytes on disk) browser.cache.disk.max_entry_size = 1000000 (cache objects up to 100 Mbytes)

Is Cache Longer Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Cache Longer requires a few sensitive permissions. Exercise caution before installing.
