UI Rated 3 out of 5 stars

Is there a user interface for this extension, or does it keep memory freed up automatically?

Not working with FF 12 Rated 1 out of 5 stars

Well,I just installed it,and found it in the disabled section of my extensions,where it is labelled not compatible with FF 12..
Badly in need of an update..

Rated 5 out of 5 stars

Using Firefox 12.0 on a Windows XP SP3 machine and RAMBack works exactly how it's intended to and works great for me. I've been testing it for hours now since I first installed it and thrown all kinds of flash and such at it that would add to the plugin-container.exe memory usage, and it handles freeing up that memory perfectly. I think the negative and low ratings are people that simply don't understand how it works, and/or are using it wrong...

+1 for a more recent version. I would be happy to contribute testing.

Please update, its been over 4 years since the last update, does it even work anymore on Firefox 10 or 11 beta?

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

Inadequate Description Rated 5 out of 5 stars

Best add-on to clear browser memory cache which is stored in RAM. Misunderstood by many as to its actual working due to inadequate description.

Doesn't do anything on my Firefox 6.0 on Linux.

"does not seem to do anything. it is a bit suspicious how the program should stil be able to do anything when it was never updatet since the initial release in late 2007."

This is spot on.

The only useful addon to free up memory

Tools Menu Rated 3 out of 5 stars

Still testing this add-on on Firefox 3.6.21. Minor issue, the "nondescript" entry under Tools Menu. If you want to change this entry to, for example, RAMBack Clears Caches, you can do so by decompressing the ramback.jar file and then by changing the ramback.dtd file as follows:

<!ENTITY ramback.label "RAMBack Clear Caches">
<!ENTITY rambackToolbar.label "RAMBack">
<!ENTITY rambackToolbar.tooltip "Clear internal caches!">

Then, re-compress (e.g., using IZArc and the fast setting) all the folders into a new ramback.jar file and place it where the original file (renamed ramback.jar.old) resides. This worked for me ..! Best, CBA

Really does make a noticeable difference in Firefox 5 but stopped working in Firefox 7 Rated 1 out of 5 stars

Stops Firefox 5.0.1 'going to sleep' when I leave the computer for a few hours.
For some time now when returning to the computer I have to wait several minutes for Firefox to 'wake up' and sometimes Windows will also display the message 'unresponsive'.
Since installing RAMBack I no longer have this problem and even in normal use I can see that Firefox is more responsive.
I have been constantly watching the memory usage of Firefox with StatusbarEx and in normal usage with say 6 tabs open it will show memory constantly being cleaned and dropping to 10mb before stabilising at around 30mb. If I leave the computer it will stabilise at around 18mb.
This means I am not constantly having to worry about my workload hiking the RAM up to near 70% or 80%.
While typing this review the maximum memory Firefox is using is 35mb out of an available 488mb.
Only takes a mere 12kb on disc as well.
I think that it does a great job.

Edit: October 17, 2011
With Firefox 7.0.1 RamBack no longer works at all.
I suppose it has done well to last up to Firefox version 5 without modification since 2007.
It is a great pity that it no longer works and that the developer has not updated it for 4 years.
It could of course be an add-on conflict but I doubt it as I have not added anything since FF5.
I have had to change the star rating from 5 stars to 1 star as a result.

FreeRAM XP Pro for Windows XP is the better choice (but note this is not an add-on)
I have now installed FreeRAM XP Pro which works brilliantly if set to 'Try to Free 100mb' and the CPU: Aggressively. There are extensive settings for full customisation to the individual system requirements. It works independently of Firefox so there are no compatibility issues to worry about. Set it and leave!

Hopefully one day the developer will update RAMBack.

Disappointing Rated 1 out of 5 stars

No effect on 4.0.1. Anyway why should I need some add-on to stop firefox eating up memory? Explorer doesn't do this, Chrome doesn't. I'm not going to upgrade to the next Firefox until they sort this out. I am fed up with this program slowing down my computer, the fan constantly running, etc.

Didn't impact memory usage much, but seemed to drop CPU usage, perhaps coincidentally.

Works well at reducing the RAM usage, however at a cost. When opening a new tab after Firefox was minimized, Firefox will hange while it retakes the RAM it wants.

If Firefox is idle, the RAM usage will drop to 30 to 50 MB. When Firefox is active the RAM rockets up. Without this addon the Firefox will slowly eat your RAM (even without any addon's installed). My Firefox will use up to 1.5GB of RAM. When Firefox gets to about 700MB of RAM, Firefox becomes 'sluggish'. With this addon, Firefox get up to about 500MB of RAM, even when active.

All in all, a good addon, however, restarting Firefox is the fastest way to reclaim the RAM Firefox wants.

This does not seem to do anything, or at least very little, no more than 60ish MB released which is nothing compared to the 1.5 GB I sometimes reach when I open a lot of tabs. Even after closing them the memory does not change much. This seems to be a problem with firefox though and not necessarily this add-on.

does not seem to do anything. it is a bit suspicious how the program should stil be able to do anything when it was never updatet since the initial release in late 2007.
