This is a brilliant idea, and in my opinion should be engineered directly into Mozilla Firefox alongside whatever functionality https://addons.mozilla.org/en-US/firefox/addon/suspend-background-tabs/ brings to the table. Firefox is a cumbersome bundle of uselessness the moment one opens more than a half-dozen tabs, and these add-ons definitely help.
Alas, this add-on has some very significant flaws which make it (for now) unusable. Specifically, the renaming of retired to "data:text/html…xyz&l;/title>". If this can be fixed and/or retired status be signified with some sort of on tab emblem iconography (a'la TabMix Plus tab protection and reload features), this little add-on would get 5 stars from me.
Is this add-on still under active development?

Hibernated tabs get a "data:text/html...xyz</title>" as a tab title (where "xyz" is the last part of the page title - it gets truncated to fit tab width). Their favicon is not removed though - which is a good thing in that it helps you guess what site/page was there before. For some of these tabs, this text replaces their url too, so reloading the tab produces an error.
(some) Tabs with google searches that get hibernated loose their search query part of the URL. The actual URL that was there before the hibernation gets replaced by the domain only part of the URL. Don't know if it is relevant, but my home page is set to Google and is fired on every new tab.
Giving the addon 2 starts for the effort and the idea behind it. The mechanics behind the procedure that fires the tab hibernation seem to work. The code that is executed in order to do the actual tab hibernation though is buggy. I'm confident this will be fixed in time. Keeping the addon disabled for now (in order to be notified of future updated versions so I can give it another spin then).

Experiance and report to improve Rated 3 out of 5 stars
There seems no change in memory used before and after installing this add-on (checked through task manager) but looks like pages are loading comparatively fast.
Only title of tab is not showing correctly (shown from history of tab), but when opened it by clicking it opens correct page. Is this a bug or is in accordance to warning "EXPERIMENTAL. MAY EAT YOUR SESSION OR DO OTHER BAD THINGS." ?
There is scope to improve this add-on otherwise very good functionality (thearotically)
Nooooooo Rated 4 out of 5 stars
there must be an option to not unload tab videos for example through a whitelist for youtube/dailymotion and so on because i don't wanna have to buffer the video from the starThis review is for a previous version of the add-on (1.0.1-signed.1-signed).

Works, and does what it promises. Good replacement for BarTab, doesn't have the problems Bartab has since FF 4.0 (some pages don't load).
Caveeat: if you decide to disable it - your session may be lost. So, maybe you should activate all tabs before saving the session (didn't tried it)
1) The settings in about:config should be created by addon itself.
2) Selective tab unloading, possibility to have some tabs (the interactive ones) always loaded.
Comparing to Memory Fox - works faster and frees more RAM. I don't know why, maybe because of Memory Fox somewhat ineffective swap file usage.

Has this been tested on FF v7? It doesn't complain when installed but it appears to do absolutely nothing to the memory ... waiting for it to unload all tabs (about 60 of them) leaves the memory completely unchanged (around 450 MB).This review is for a previous version of the add-on (1.0.1-signed.1-signed).
Maybe Memory Fox Rated 3 out of 5 stars
Just found Memory Fox addon. Seems to be well received. May be a better approach to the purpose of Dormancy.This review is for a previous version of the add-on (1.0.1-signed.1-signed).
It needs bug fixing Rated 3 out of 5 stars
1. I don't like the system with check intervals. In my opinion - every tab should have some internal timer, which starts counting time since the tab became inactive. And when that timer reaches extensions.dormancy.TabDormancyAgeMs value - the tab should be put to sleep
2. I use Tree Style Tab and your extension breaks trees, when putting tabs to sleep. Sometimes, they get back to normal trees, when re-activating the tabs but only sometimes...
3. Titles of the hibernated tabs look like this: data:text/html,<title>The actual tab's title</title>, but when they get restored - usually their titles get fixed, but sometimes they do not.
4. Hibernated tabs have crop=center instead of crop=end.
5. Bug 675541 should be marked as dependent to the Bug 675539. This bug is about styling the stalled tabs, I suggest adding opacity: 0.8; to them.
6. Sometimes it wrongly stalls a pretty fresh tab (e.g. I'm sure that the tab was too fresh to be stalled: it was inactive for like 3-5 sec [I just switched from it to another tab] and the Age pref is set to 300000.
