Useful, but should be enhanced Rated 3 out of 5 stars

Firstly, I gotta point out that it is a fantastic idea. But it is not very user-friendly. I am using FireFox 3.6.13 on Windows 7 64-bit system, and clicking the pause button does nothing. In addition, the only two items showing up in tab context menu is "Pause Tab" and "Pause All Other Tabs". And shortcut to "Pause Tab" does not show up, but I tested my way to find out that it was Ctrl+Alt+P.

You should really add user customization abilities. Features like: "Unpause tab on focus", "Disable pause icon (on mouse hover)", "Custom shortcuts" would be highly appreciated. You could also consider integration with Tab Mix Plus, so that SaveMemory actions appear in the lists of Tab Mix Plus. (Things like middle-click tab="Pause Tab" could be possible through that.)

Rated 4 out of 5 stars

Works fine, but loses a star for changing the favicon on unpaused tabs when my mouse just happens to go across it (latest non-beta FF for Mac), making it looked like unpaused tabs are really paused (when they're not the active tab, that is). Fix that and you'd get the star back.

Maybe it would be nice if it automatically unpaused tabs when you open them, but now its very irritating if you always have to click at "unpause tab". For me, it isn't a worthfull add-on to have! The pause icon is also irritating.

It worked the first time and then it didn't work anymore.

Rated 5 out of 5 stars

Now that the speed of my Firefox is again increased with what we can call the more relaxed version of mozNetworkPrioritizer resulted from a combination of two unique add ons, one imported from Safari and the other from the entertainment world of Kutless band fans we can still be looking around for a replacement of moznetworkprioritizer, but not a relaxed one with just 75% up to 90% of its features, ... if possible lets try having a 100% replacement of that excellent extension of Firefox 3.5+ And I found SaveMemory which is a manual turn off and on of the opened tabs changing their status from active to inactive and back, while almost completely removing them from the RAM visibly gaining more RAM. The difference between this SaveMemory and mozNetworkPrioritizer is just of "user" ... SaveMemory requires from users a manual, human control of the opened tabs ... which works fine when we have under 25 tabs opened. Users of mozNetworkPrioritizer are certainly working with more than 25 tabs or are rather moving fast from a site to another or a tab to another and the add on does its things automatically without the need of manual control. Was just one complaint to this add on (leaving us to figure out) saying that the more we use SaveMemory the higher the paging file will be ... and the uncontrolled increase of paging file is the cause of crush or slow down for many old processors, but the complaint is really one of a kind: the add on doesn't save or cache, doesn't record anything when "pausing" the tabs (setting them to inactive mode). It says "pause" but actually it shuts down the site activity in the browser, leaving the tab opened and storing the address in history. Why would a PC need more paging file when is closing sites previously opened? Sure wouldn't need it and the complaint is a sign of how few things people know about the best extensions of Firefox.

Icon bug :-( ...Everything else :-) Rated 4 out of 5 stars

The tab icon bug where the "pause" icon is displayed in place of the web page's favicon is really irritating.

Other than that, things seem to work as advertised. CPU usage is down to between 20-35% on average, for around a dozen open tabs -- and best of all, no beach ball of death so far.

Haven't yet tried to see how it would handle the normal load I put on the browser (20-40 tabs per session).

This user has a previous review of this add-on.

Additional feature ideas, and Patience required. Rated 3 out of 5 stars

Ok, first, just to get it out of the way- the error with the button not resetting has been fixed for most webpages. However, this still does not work for pdf files being read in the browser. Overall though, the addon does what it says, as my firefox is running on severely reduced memory.

Also a few ideas:
It would be cool to have an auto pause feature, so that after a certain amount of time, an inactive tab will be disabled. Also, something rather opposite that, an option to have tabs reactivate as soon as they are clicked. And, to go along with the first idea, it would be cool to have a whitelist, so that certain pages could be set to not disable ever (atleast on the timer) ie facebook. Those are just some features I'd like to see.

Will eat more memory in PF Rated 1 out of 5 stars

Be careful when use this, after use this software your Firefox memory in Page File will increase, if pause page will increase more!!!!

interesting... Rated 4 out of 5 stars

looks like an interesting product, but looking at the code i found a way to get rid of the "pause icon" on the tabs, make sure of know what are you doing first:
- search your firefox extensions folder
- follow the way searching extension@savememory.com then chrome then content
- open with notepad or similar the file "savememory.js"
- go to line 87 and change "icon.src = savememory.PAUSE_ICON_SRC;" with "//icon.src = savememory.PAUSE_ICON_SRC;" (yeah, just add "//" before that line, you can also remove that line but its not recommended)
- save and exit, then restart firefox (or close it and open it again)

thats useful if youre using another program that changes the favicon (like toomanytabs) or youre tired of seeing pause buttons everywhere, i hope the developers solve this issue soon (or at leaast give an option menu to disable that pause icon appearing in all the tabs, theres already a "preferences.js" with just one preference and no "options" menu on addons window)

Rated 3 out of 5 stars

Yeah, nice add-on, but favicon issue needs to be fixed!

Needs work... Rated 3 out of 5 stars

Potentially very useful, but I agree with Axelock, the pause icon on the tab is strange and highly annoying.

Permanent pause icon bug Rated 3 out of 5 stars

Great idea, good work! But the implementation is bogus.
When I hover above a tab's icon, it changed to a Pause icon, and NEVER change back.
In few minutes I've faced a lot of Pause icons despite of no paused tabs.

Nice idea, but tedious Rated 2 out of 5 stars

It is a nice idea, but you will have to train yourself to click and pause any tabs you are not using at the moment. That can be fairly tedious.
If you don't mind doing that then it is a good product. If your like me and don't need another thing in the right click menu or action to think about on a regular basis then this will not do you any good.

Still have a bug Rated 1 out of 5 stars

This extension still have a bug, that cannot pause unused tab..
firstly appears have pause sub-menu, but after for few days.. they're missing ????

Good start, needs work. Rated 3 out of 5 stars

The addon doesn't start unless I start Firefox(the addon is NOT active) disable then re-enable the addon and then, restart Firefox. This process is easily repeatable and appears to be necessary in order for the addon to become function-able for each use.

Works when I MAKE it work...lol.

No Options on Tabs Rated 2 out of 5 stars

I wouldn't say this here but I see no forum or such for this.
I've tried installing & restarting Fx twice & I see nothing in the tab context to work this extension. I looked in all my extensions to see if they were hidden but were not. I'd love to give this a try as SkipScreen is the best but for now have to fall back on BarTab.

Sounds good, but... Rated 2 out of 5 stars

In principle, it sounds like a great idea... but it doesn't save the tabs that are paused when you close the tabs in a session manager. Also still appears to use huge chunks of memory even when everything is paused. Uninstall.

CPU Tamer Rated 5 out of 5 stars

If you're not using Firefox (FF) because too many tabs slow down your pc, then check out SaveMemory. I typically have 40+ tabs open in FF 3.5.7 (the most stable release, IMHO) but most tabs are just to hold my place till I get time to revisit them (and their backbutton history). Memory used is approx. 300,000k.

I installed SaveMemory, checked Task Damager for memory and cpu use, Paused all Tabs, restarted FF (using the very handy QuickRestart addon), rechecked Task Mangler and found that memory use had been reduced by half. CPU use is nearly down to zero. Sweet!

Memory does tend to creep back up but restarting FF brings it back down. But the reduction in the cpu load is the main thing and something I've been unable to "tame" till I discovered SaveMemory (July 10 '10). Kudos!

Rated 2 out of 5 stars

Nice add-on, it works, but only a little bit of the time, like right now the little pause icon doesn't show up, the only time I could do that was after I installed and restarted, why is it doing this?

Rated 4 out of 5 stars

I like it though I thought it would require less interaction. For example, I expected that all background tabs would be paused and unpaused when in the foreground. Some sites could be whitelisted so they are always unpaused. As it is now, I have to make the pauses happen.
