TIL that on Firefox you can unload tabs from memory without closing them (lemmy.world)

The feature is called Tab Unloading, and weirdly enough they made it not easy to access despite its usefulness.

You basically have to type about:unloads in the address bar and hit enter. If you then click on "Unload", it will put the least used tabs to sleep. If you keep clicking that button until it's greyed out, you'll have unloaded all your tabs from memory.

This feature is handy if you want to temporarily switch to something that is memory hungry without having to close your 100 tabs.

It doesn’t save form inputs because when you click a suspended/unloaded tab, it reloads the whole page. Everything unsaved on that page is lost.

I really hope some day Firefox will work the way you say, though.

That's weird then, because this says:

The tab’s scroll position and form data are restored just like when the browser is restarted with the restore previous windows browser option.

If it doesn't do that then I'd say it's a bug?
