Hey i can't move icon of cache status.

Good add-on Rated 5 out of 5 stars

This add-on is MUCH EASIER than going to about:cache and converting the kilobytes to megabytes.
Instead, it sits on your add-on bar and tells you the size of your cache in a more "friendly" unit (MB).
And, for those of us with small screens, allows a more compact mode.
Nice job.

Speed up FF by clearing disk cache. Love it. Rated 5 out of 5 stars

Sits in the Add-on bar. Displays the status. Works on FF 21 perfectly. I agree with Mark M's comments. It a "must have" to manually clear a bloated disk cache - quickly.
P.S. The OK button in options works for me. Win7Ultimate.

great addon - thank you :-)

Buggy Rated 2 out of 5 stars

2 bugs that needs fixing:
1 - Nothing shows up in the status bar.
2 - The OK button in options doesn't work, however, if you change your options and press cancel, it will be saved!!

Please fix these bugs as it is a very good and useful add-on, thanks for your efforts.

Lacks a lot of features. Doesn't show on the addons' bar for me in firefox 15.0.1. Cannot access it other than from the status bar which does not exist. Clicking Ok in the options does not close the window... Needs a refresh maybe the compatibility isn't there anymore.

Gotta love this one!!
I have been using CacheStatus since 2006 when I was searching for something that would make it easier to clear my browser cache. Little did I know this add-on would become part of my browser workflow. As an online educator, clearing cache is a common troubleshooting and preventative measure when operating in our learning management systems. Going to Tools>Clear Recent History and specifying clear cache takes too long when compared to CacheStatus. This add-on is more than just a cache clearing tool, it allows the user to see the build-up of browser cache. This is great to prevent issues related to bloated cache. As an Ed Tech Coordinator, I recommend this tool to my colleagues as a great way to track and clear nasty browser cache.
Love it!

RE: Disk Cache Not Loaded Yet Rated 5 out of 5 stars

If you chose to have Clear private data at shutdown then the disk cache is disabled. Not a bug but a feature in Firefox 11.0 to help with faster shutdown.

Good addon but please add a "clear cache" button

Deceptive, creates problems & useless Rated 1 out of 5 stars

This is deceptive, creates problems and is next to useless (totally useless for many users).

It looks good on first glance. Allows you to see in real time what megabyte levels your disk and memory cache are.

But as another reviewer below noted, *this does not actually clear your disk cache when you tell it to*. When you right click the MB numbers the add-on provides, then select "Clear Disk Cache" (or "Clear All Cache"), this doesn't just delete the cache as the Firefox built-in "Clear Now" button does. Instead, it oddly shifts your entire disk cache to a new folder called "Cache.Trash".

If you put your cache folder on a limited-space different disk drive to improve performance and save space on your system drive, this behavior both causes your disk to fill up substantially faster and potentially run out of space. For those who don't move their cache to a different disk, this poorly designed add-on instead increases your disk fragmentation needlessly, as well as uses up disk space.

As well, if the poor disk the cache is on runs out of space due to the idiocy of how this works, the add-on can't actually "clear" any cache at all. The number shown on the status bar (etc.) never actually changes and nothing is done. Due to the fact, as noted, it doesn't actually clear the cache; it instead shifts the entire cache contents to a new folder.

Finally, it fouls up the built-in Firefox 7.x cache clearing function (which actually works properly). When you go to Options, Advanced, Network, it no longer tells you "Your cache is currently using ***** of disk space". Instead, that entire line is blanked out. As well, clicking the "Clear Now" button no longer functions.

So highly recommend to find a different add-on to clear your cache and stay away from this one. At least until the author changes it to actually function as they claim it does.

(EDIT: replaced ampersands that this forum can't handle with "and")

No deception intended...

I originally wrote this back during Firefox 1 and I needed an easy way to clear the cache and it grew from there. I admit I haven't kept up with Firefox's progress through the ages that well, but I welcome code contributions. :)

If you're experiencing issues, it may be a conflict with another add-on.

I admit I'm no JavaScript / FF expert, so I definitely welcome patches and pointers on how to do things right. :) My code is publicly available at:



How do you get this addon? Rated 1 out of 5 stars

Every time that I try to get this add-on, from different areas on Firefox I get the following message:
The add-on could not be downloaded because of a connection failure on addons.mozilla.org.
I read some comments on the forum pages and none of them work for me to download plugins.

You can download it from here...

I really enjoy this add-on. I'm looking forward to the update to Firefox v5.0. Thank you!

Works perfectly for me :-)
Great add-on, thanks!

cache.trash folder? silly Rated 1 out of 5 stars

what good is clearing cache if it just dumps the old cache in a cache.trash folder? waste of time

Rated 1 out of 5 stars

Kind of cool. Although it does not auto clear RAM usage. "It can also automatically clean your cache when it reaches a specified level" I watched FF go from 420MB to 528MB (the limit I set is 512) and beyond with out much of a peep from this to control it.
FF was minimized and left for a few hours, RAM usage just kept climbing up and up too over 1GB. Any other RAM limiters for FF out there?

Rated 5 out of 5 stars

great add-on. works well for me in FF4.

@ commus: icons should be in the 'Add-on Bar'.

How is this possible with 4.0? Rated 1 out of 5 stars

How can it work on FF 4 when there is no status bar? I also lost my weather bug because of this.
