Ability to enable, disable and configure tab unloading from the Firefox settings page

[GammaRay]

Firefox has a feature that unloads some tabs to save memory, but there is no way to configure it from the Firefox settings page. You can only turn it on or off in about:config, and there is no way to configure how it behaves.

There should be a setting in the Firefox settings page that allows you to turn tab unloading on or off without navigating to about:config (similar to the 'memory saver' feature on Google Chrome). Additionally, there should be options in settings to configure tab unloading, such as changing how aggressive it is, or changing the weightings of certain types of tabs (eg. making pinned tabs just as likely to be unloaded as normal tabs).

The option to change the weighting of tab types, in particular, would be very useful to me. I personally pin the tabs that I access less often, and leave the ones I access more often unpinned. Which means the tab unloading feature does the opposite of what I want, and I often have to unload my pinned tabs manually.

Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.

This is a feature that would make using Firefox a better experience, IMO.

I currently have about 50 tabs open due to the tree style tab manager. Configuring tabs to auto-time out would be nice!

Please put an option, "put to sleep all tabs in the background."

+1!

Unload feature need to be more transparent and configurable. Especially when ff is really ram consuming

It would be great to be able to disable tab unloading on Android when there is enough RAM available. Since v134 update, it seems that tab unloading is more aggressive, and it's a problem with one specific site I would prefer it never unloads.

This needs to be implemented, especially as it seems unloading at low RAM usage is disabled on Linux. Many websites are very RAM heavy nowadays (like new reddit) and I usually have a lot of tabs open, to get back to later. On Zen browser which implements unloading after a timeout, my system's RAM usage only ever reaches 5GBs which leaves room for so much other stuff, the same thing on firefox easily crosses 13GBs which is dangerously close to my available ram (close to 15GBs) and so my computer freezes a lot.

I like how lightweight Firefox is, but this makes it kind of unusable. It would be so much better if Firefox did this by default or gave an option to do this, which afaik cannot even be done by tweaking about:config
