how to open many tabs in chromium but unload/disable inactive/notCurrent ones, releasing memory and cpu?

Question

So I have 50 tabs opened on chromium, but that is using too much memory and some of the CPU.

How can I have all those concurrent researches I am doing opened but not clog my machine?

I think there should have a way that only the active tab is loaded in memory and running, and all the others should stay closed/unloaded from memory, until I want to look at them...

Any extension can do something like that?

EDIT: tabs outliner seems to do the trick as @Danny Beckett said, but I still wonder if the non active tabs could be unloaded (automatically); may be something like keep only the last newest 10 tabs opened/loaded, and auto-close the older ones; may be tabs outliner can have that feature in the future, just need find a proper way to ask its developer... any other tips?

EDIT: here a link to the idea: auto close old tabs, go there and upvote if you like it!

Answer 1

The Tabs Outliner extension does exactly what you're asking.

Answer 2

• Type command "chrome://kill" (or "chrome:kill") in the address URL bar (like a http:// URL but with chrome:// first) to individually release tabs from memory.

• Otherwise for a GUI, in the standard Chrome Task Manager (type Shift-Esc [or go to menu "More Tools..." then "Task Manager"]), then just "click-to-kill" the tabs you want to release from memory.

That language command is painful/difficult/violent/triggering but will not crash your computer or cause harm, that is the actual English command.

(I too use and love the Tabs Outliner suggested before, but still sometimes type the command.

Pro Tip: Make "chrome://kill" a convenient link in your Bookmark Bar.

Other benefits to the command version, are that if you reload the page, Chrome with chrome:kill still has it cached, so page position and form fields can be restored automatically. However with Tabs Outliner it wil not remember the reloaded page contents, there is not any cache.)
