This add-on works (as my memory drops dramatically in a matter of minutes after install with over 100 tabs open) but nowhere can I find the options to set suspend time, whitelist urls, ignore/disable items (as shown in your screenshot). How about some basic information on where this can be found & what to expect on install?? I've uninstalled/reinstalled/rebooted to no avail. Moving on to another add-on

It works great and has good utility to manage what type of tabs (whitelisted, pinned, audiable) are suspended. Its downside is it can spike your disk usage and cause Firefox to not respond intermittedly.

This add-on does the job it sets out to do flawlessly, maybe a bit too flawlessly if you just reinstalled your browser or OS or moved to using some fork/different edition because other than saving your whitelist and settings locally (as part of the ~/.mozilla directory on Linux, macOS and Windows you are on your own but Google's your friend) but does not take advantage of Browser Sync (nor is able to be parsed automatically by it if that's even a thing, which is not something I would trust Mozilla not to turn into a dumpster fire fast like a NASCAR), does not offer a means of exporting the settings then importing them for the back-up conscious but Mozilla leery among us like myself or save its settings in a way I could at least snatch easily from my profile directory to encrypt right fast and throw on Dropbox.

That means everytime I switch to a new fork/edition or crash my Linux install again and have to reinstall the OS (which in using macOS I found I also did pretty often, what can I say I like to experiment) I have to build my entire whitelist over again at the expense of tabs suspended I looked away from without checking the extension and variable amounts of work lost and years taken off of my life in the resulting fury prompting me to determine that there is no way of easily accessing, backing up and later restoring my settings to prevent that from again happening.

I get why these features, from a Unix philosophy standpoint, might be merely bloat or additional complexity that means additional points of inevitable failure and hours spent working on the extension that has been otherwise feature complete the whole 6 years I have used it but at least an import/export feature to spare me the hours of lost work would have been really nice and is why I dock the one star despite otherwise being impressed with how well this add-on has held up in my otherwise constantly rotating add-on insanity that is part of my firefox web browsing experience I deeply prefer to Chrome, all of its stupid gimmicky forks (brave, edge, arc, garbage the lot of them and all too deeply tied into the ever creepier Google madness under the hood whatever half-baked privacy mitigations they pretend to have and dress up with animations) and even the functional webkit alternatives that exist, or LuaKit (because Lua > Python for configuration scripting qutebrowser is too obtuse even with the active community around it) or the terminal based options that I really want to be good but are just really awkward trash.

It's working great!

But I have a question. I often open the same tab session. There are a lot of tabs. On some of them I used the "Don't suspend this tab" option.

How can I see which tabs have this option activated? Or maybe I can disable this option for all tabs at once? Thanks!

Been using for over a year. Works automatically in the background and I've been able to have close to a hundred brower tabs which are suspended. It allows to modify the time before suspending, from 5 seconds to 1 hour. Highly recommend.

this one actually works

❌ You click on it and it doesn't do anything or suspend any tabs, literally just open the menu and that's it. Useless.

Good for the most part but need the option to never suspend a specific domain.

This works very well, but if you don't want it to interrupt download services like Mega.nz, you'd better add them to its whitelist. If you do, when you switch away from their tabs (even though the tabs are already loaded, right?), it can stop them in their tracks.

Only one extension that correctly works for me. I'm glad to see that it has a options for settings

Serves its purpose, similar to Edge's Sleeping tabs

WARNING! Will suspend tabs with active forms meaning you will lose any information you have entered. I've recently moved from Chrome to Firefox and used Tiny Suspender on Chrome for years and it has this functionality.
