Firefox should suspend tabs to better performance

[EduardoBernal]

Firefox isn't with useful tool, which is tabs suspender, it saves of much hardware consume and doesn't allow your PC stay slowness and/or your own internet, because tabs can consume internet and recourses in background without you use it, so that's important and should be in all popular browsers including Firefox. I recommend they base on auto tab discard and possibly performance tool (by Microsoft Edge), because auto tab discard extension is really complete and very useful, mainly it saves where you stop on certain time video and performance tool saves much your recourses on your computer and is very efficient:

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

I swear I've seen an idea about sleeping tabs, but, surprisingly, I can't find it now, strange

I think attempts to optimize performance based on PC specs should be incorporated.

I support this because for a machine with 16 gigs of ram I only got twitter open in 1 tab and 1 window but this doesn't look healthy to me

So this would be like ‘sleeping tabs' in Microsoft Edge, right? I like that feature when I have to use Edge at work and occasionally at home.

@steel835 great memory! It was an idea from Ideas@Mozilla (25 votes). We'll keep that in consideration when looking into this idea 😃

[KERR]

Yes please! I use Auto Tab Discard for this, as I have tabs that I haven't used in days but need to come back to. Makes no sense leaving them running and consuming resources - and they really do end up eating RAM/CPU/battery.

I think the key here is to ensure there's an obvious way to "never sleep" a particular tab. Eg you may not want to miss an ebay auction or a web notification (email, instant message, MS Teams).

As a start, sites like Youtube, pinterest, web search could be snoozed with minimal impact.

I feel that memory consumption has increased since the number of content processes can no longer be changed in the settings. Is it possible that it is not adjusted according to the physical memory capacity?

[Thatsygure]

I swear they announced a feature like this was implemented, but only automatically on certain circumstances (that I can't remember) and not on command, but I can't remember which version it was.

Kind or like seat belts in cars today, should be a standard feature to help with Memory Foot Print of FF, Don't tell anyone but I had to move to Edge at work as no Group Tabs , kind of embarrassed. Can't wait to go back to FF when the Group Tabs comes back and becomes standard built in feature. Keep up the good work on the new Features FF Dev Team. Thanks 😎👍👍👍

Hey all,

Here with an exciting update…

Your idea has quickly received a great deal of votes (kudos) and support here in the Mozilla Connect community, so we are upgrading the status to “Trending idea.” This means it’s now one step closer to reaching our internal teams for review—learn more about The Idea Journey.

Please keep the conversation going and stay tuned for updates 😃

I'd wholeheartedly appreciate this feature. Auto Tab Discard and the like has long been staple extensions on lower-end systems, but even I see significant improvements in responsiveness on a high-end systems as well (i7-12700K / 1 TB SSD / 32 GB DDR5-6000 / 400 Mbps cable).

Microsoft Edge has also released some statistics on how well the feature works: pretty dang well.

Sleeping tabs in latest Insider testing in Microsoft Edge typically increases battery life as a sleeping tab uses 26% less CPU on average compared to a non-sleeping tab. It also reduces memory usage by 16% on average. Your overall savings with sleeping tabs will vary based upon your browser usage and the total numbers of tabs you use. The more tabs you have, the more savings you’ll see. While individual device performance can vary and depends on configuration and usage, Microsoft Edge Insiders have shared that this decrease in resource and battery usage has improved their browsing experience.

I'd like to add a few notes to this idea, if possible:

1. Allow users to control how long a tab should be idle (e.g., unclicked / unopened) before it's put to sleep. I'm quite aggressive and have set mine to 30 seconds of inactivity.
2. Fade the colors / text somewhat on the tabs to let us know it is asleep.
3. Ensure there is "instant" wake-up, e.g., a user shouldn't be able to tell the site is restarting / being woken up, within reason of course.

To @Jon and whomever it may concern:

1. Especially under memory stress, serialize to disk and completely remove from memory.
2. Give a warning on new tab open (or even when tab has been active for a while!) that the machine FF is running on is about to get really ignorant if the user continues what he/she/etc is doing.

Why FF devs believe in the myth and mystery of infinite memory is beyond me, especially when an empty tab takes tens of megabytes...

@tripleo

1. this option would be interesting if page scroll state and page navigation history would be preserved upon reopening the page(extensions like OneTab and BetterOnetab(Chrome addon) don't preserve such states.)

Also AutoTab Discard addon is better than any other solution including Edge's (per Edge's performance info that its options only allow for partial saving of PC resources - AD saves both CPU and RAM as nothing? is left of the targeted tab(s) in the background). 

Why the need for a native feature?

[Yangu_Hury]

Firefox uses too much CPU time when minimized. I need to create a new tab and then minimize to avoid the high loads because the non active tabs gone to low priority.

I suggest to put all tabs in the window no matter if active to low priority when Firefox window is minimized.
