how do you use this thing? Rated 1 out of 5 stars

there seems to be no interface and it doesnt make any difference in my system that is worth while. that along with the terible lack of information involving how it works or what kind of results to expect make this extension pretty much worthless.

RAMBack works just great ! Rated 5 out of 5 stars

Before I have installed RAMBack, I had often hangs of Firefox due to big RAM consumption (approx. 500 MB). After RAMBack installation, now Firefox take only 280 MB and works fluently! :-)

Works. Not very well documented, though Rated 4 out of 5 stars

It does what it claims to.
Why the developer didn't simply add "Go to Tools and then click on Clear Caches" to the About this Add-on section of the add-on page is beyond me. Seems like most of the negative reviews are from people that didn't know where to look and it could all be made better with that simple note.

RAMBack DOES NOT WORK! Rated 1 out of 5 stars

And if you read some of the reviews, the developer is pretty rude, as well.
Too bad you can't give it 'No Stars' because that's what it deserves! In fact, I have a feeling the memory usage will go down a good amount once I remove it. =/
LMFAO!

Освобождает около 8% используемой Firefox'ом памяти Rated 1 out of 5 stars

Работает только по нажатию кнопки. Firefox потреблял 915 Мб, после нажатия кнопки в течение 40 секунд потребляемая память уменьшилась до 815. Пока я писал эти строки, Firefox стал использовать 900 Мб. И нахрена козе баян?

Can not find where to use Rated 1 out of 5 stars

just added see in extensions but not how to turn on to use. have firefox 45.0 any1 can maybe help? would be appreciated.

Simply does not work. Rated 1 out of 5 stars

I wanted to like this plugin, I really did. Everyone except for the Firefox development team is aware of the horrible memory leaks in Firefox, so the idea of a quick fix button was great.

Except, you know, the button doesn't do anything at all.

Maybe it's because I'm on a Mac, but watching the memory usage of Firefox in Activity Monitor shows little to no change when using Ramback. I tried letting it sit, I tried pressing the button... alas, nothing worked.

Well, that's not true. Closing Firefox worked. And it's possible that deleting Firefox and going with a different browser would work too, but I digress...

In any case, good idea, poor execution.

Works! Rated 5 out of 5 stars

Use the menu bar, tools->clear caches. See a huge drop in RAM usage. Thank you for this add-on.

Fixed Firefox consuming gigabytes of RAM Rated 5 out of 5 stars

Firefox would consume 2 gigabytes or more of RAM before I found this fantastic add on. Firefox would slow down to a crawl if I were on a video page and I'd watch the RAM usage climb.
RAM would be used up regardless of whether I was using HTML5 media player or Flash to watch videos. It was absolutely terrible dealing with Firefox slowing down to a snails pace.

Now, I have 4-5 tabs open and watching a youtube video. RAM usage is under 360k although I saw it go as high as 402k before it dropped to around 360k again.

Testing still going well. I watched a long video and noticed RAM climb to 500k. Ten seconds after closing the Firefox tab, RAM went back down to 360k. Before using RAMBack, I had to totally close Firefox, wait nearly a minute before RAM was released. Thank you RAMBack for making my day!

Not User Friendly! Rated 1 out of 5 stars

What I mean by that is not all of us are 20 something computer wizards, and need a bit more clarification on how this works. Since Mozilla uses it as a link to help with Memory issues that are plaguing Windows 10. It would be nice to know if we need to or don't need to press a button or if it is internal. 1 star for lazy description of product.

Very helpful Rated 5 out of 5 stars

Having almost given up using Firefox because of increased RAM use since v42 taxing/overheating my laptop, I am very pleased with RAMBack for reducing per-tab use from over 100M per tab down now to about 60M per tab. Good work!

Does absolutely nothing Rated 1 out of 5 stars

It does not force FF to release memory when tabs are closed. Documentation on its use is non-existent. No mention of the "Clear Cache" option installed in the Tools drop-down menu, which does nothing more than the "Minimize memory usage" button in about:memory. A totally useless addon.

Very good! Rated 5 out of 5 stars

Works very well. My memory used to go as high as 1,500,00, and now RAMback keeps releasing memory after closing tabs and it is around 650,000. It works in the background, the user doesn't need to do anything. If you want to watch it work, bring up Windows Task Manager and watch firefox memory before installing and after installing. Watch how the memory goes up after opening tabs, and how it is released after closing tabs. Firefox did not do that before installing RAMback. I am using Flash Control addon for stopping flash. Do not use "Youtube Flash Player" addon with "Flashblock" addon, it seems to make things worse.

BROKEN! Rated 1 out of 5 stars

Negative 1000 stars. I put this add on in and instantly over 100 new tabs opened up WTH? !@# Piece of crap, stay away.

Rated 5 out of 5 stars

Whilst it didn't reduce it to something magnificently small, it did reduce my memory usage when using about 6 tabs from 700,000k to 265,000-300,000k. Definitely better!
