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.

    Firefox does this automatically to prevent crashing. There’s no real reason to unload tabs manually. If your operating system or Firefox needs more memory, then it will unload the tabs automatically. Unused ram is wasted ram. Don’t be scared by ram usage going up, it gets freed on demand.

      There are reasons, and there are addons that allow you to unload tabs via their right click menu.

      For me it is a way to keep tabs in a window for organization without them using cpu. In some sense it’s like replacing tabs with bookmarks that integrate into the browser like tabs.

      Especially for school, I would have 10 to 15 tabs open per research rabbit hole. With lots of different assignments due, I’d have maybe 3 or 4 of these going at a time. It’s much easier to keep them open than to bookmark them and try to find them later.

      That’s fine, do what works for you. I usually have 50+ tabs open, sometimes >100. I’m a software dev, so I’ll typically have the following:

      • a dozen or so JIRA tickets
      • a dozen or so GitHub PR tabs
      • a dozen or so documentation tabs
      • several background tabs with stuff in listening to (usually music or streams)
      • several SM or news pages (for breaks)

      When I finish a project, I’ll close everything and start it all over again. I basically use tabs as a mixture of to-dos and bookmarks, but only for things I need in the short term.

      My personal computer usually only has 20 tabs or so, mostly with gaming wikis or shopping pages.

      It works well for me.

      Personally I use simple tab group that allow you to separate tabs into groups that you can open in different windows. It’s extremely useful but it means sometimes if you switch between multiple tab groups you might have a lot of tabs open, but using this would allow you to majorly mitigate that problem.

      This, if you want to act on something later, just create a bookmark and set a reminder, act on what you need, then close and move on, don’t clutter your browser and your head.

      Usually, i open one window for each task, so i don’t get a lot of unrelated content mixed up and loose focus. I rarely need more than 1~5 tabs.

      They cannot juggle 100 tabs.

      Simple as that

      Its not possible to manage for anyone.

      Theyre just too dumb to close them

    I would like the opposite though. When I used chrome, my WhatsApp web tab would load even if I didn’t open it, so I still got notifications. In Firefox I have to manually switch to that tab every time I open it.

    “Auto tab discard” is the name of the add-on I use that also uses this functionality. Highly configurable for automatic discarding (based on total count for example), and also allows manually discarding with a click (or shortcut, I think).

    I use the addon Sideberry (for vertical tabs) and it brings the option to unload specific tabs with it’s context menu.

    I don’t get why about:unloads doesn’t let the user decide which specific tabs they want to close.

    • From what I understand it basically just saves the minimal state possible (URL, form inputs), which is lighter than keeping all the rendering details in memory, so maybe that minimal representation still stays in RAM as its footprint would be negligible.

      It gets thrown away. When you go back to the tab it will effectively reload.

      (It will attempt to save some extra information such as scroll position and form inputs but this isn’t 100% reliable so I would treat it as a nice-to-have not something to rely on.)

    IceRaven, Android FF fork, has this feature as an option, and it’s very cool when using permanent private browsing mode. It makes it less likely that the OS will kill the browser in the background.

    I’m pretty sure that Chrome does this automatically. When I work I usually need about 98,000 tabs open at a time and often I don’t actually click any of them but I need them.

    Anyway I will often open a tab and have to wait to it for it to load. But I’ve played around with it and I don’t seem to be able to get consistent results so I’m not sure what parameters it’s using.

      No, no you don’t. IF you aren’t accessing stuff on them, you don’t need them open. Keeping 100 tabs open for later, is stupid.

        It also doesn’t affect performance because Chrome closes them as needed so why not?
