Reduce Chrome's memory usage by setting inactive tabs to sleep or system memory is low

Description from store
Lightweight extension that reduces Chrome's memory usage by putting inactive tabs to sleep.
Using Chrome's built in tab discarding feature, when a tab is inactive or system memory critically low, the extension discards the background tabs freeing up memory.
Once you switch the focus to the sleeping tab, it gets automatically reloaded. Tabs playing audio or video won't be put to sleep.
=== Main Features===
Tabs are put to sleep when not in use for 10 minutes (the interval can be customized in the settings).
Tabs are put to sleep when system memory is low. The extension will set a default low memory threshold depending by the total amount of system memory. This value can be customized.
The extension will periodically check the amount of free system memory. This interval is set by default to 5 minutes and can be customized.
========================= CHANGE LOG =============================
v.1.6 : support for V3 manifest and small bug fixes

- (2025-09-01) Benjamin Reed: Leaving a bad review because the dev doesn't seem too polite in the reviews.
- (2025-08-26) Dino Dude: Very good, memory went from 35 to 18 great extension would reccomend
- (2025-05-29) AssortedMold268: Works great, cut my chrome memory usage from 5 GB to 1.5 GB (trust me that's good by the standards of my lobotomized gaming laptop). Any problems the negative reviews mention have been fixed by now. Do be warned, it does reload all of your tabs at the same time upon installing which might cause memory usage to go up momentarily, but after that there have been no hiccups so far. Would be even better if there was a feature to choose specific tabs to not auto-close.
- (2025-05-10) kaboom: Works perfectly! I hope people realize that they should read the mechanics of how this extension works. By the way, maybe change the wording from "Discard all tabs" to "Put all tabs to sleep", it made me a bit confused at first!
- (2024-09-16) Daniel “The_AgentBoy” Daniels: pretty good. but chrome already has this
- (2024-08-21) Ravindu Goonewardena: So there's a problem with this extension where selecting to open a link in new tab just returns an about:blank page this started happening recently if that helps No other problems so far
- (2024-07-19) Dank Memer: Bro i installed it then closed all my tabs and i could even change the settings and it conviniently happend after I installed the extension.
- (2024-07-08) Hasan Mansour: Worst extension ever. Closed all my tabs before I could adjust any settings and completely deleted them, couldn't restore them through the extension or with Ctrl+Shift+T before or after uninstalling it.
- (2024-04-27) ajsea1sy: Atleast now Chrome isn't bugging me about memory being full
- (2024-04-27) Dan S: This extension was the cause of not being able to open links to in new tabs (command-click links). I had to disable all my extensions to figure out which app was causing this annoying problem and it turned put to be this. So writing this review as a warning to other users who might be experiencing this problem.

- (2023-09-01) Rant: I'm using windows 7 still, and i just love the old comodo dragon because of its lite use of memory even when opening many tabs in Youtube. (i've open at least 10 tabs of Youtube and less than 1GD ram usage). with this memory saver, i realized when you try opening another link to a new tab, the tab goes blank. Maybe the developer can do something about it? i know and understand its old and outdated versions i'm using if they are not willing. Seems to help a bit with the memory i would think this extension.
- (2023-07-09) Tête à-tête: I'm used to 'freemem' for mac, which can be configured. I installed memory saver to an 8-gig dell vostro and, it needs no configuration. I immediately saved 1.1Gb and swap activity dropped, and levelled off. Excellent!

- (2023-05-08) SenusSuns (Hydracoil): Useless extension. I had tabs I didn't want to snooze and I installed this thinking I could customize it but instead all it did was snooze all my tabs and ruined everything. DO NOT INSTALL!

- (2022-02-11) Mark Solomon: Does what it suppose to do but buggy. Breaks open in new tab. Seems inconsistent as to which tabs to discard.

- (2022-02-09) Kevin Pinel: Need it to leave pinned tabs alone. I think most of us pin tabs for a reason. Be nice to have a bit more configurability in it so that users can set exclusions if pinned tabs aren't going to be excluded
