Currently broken by JavaScript changes in Firefox 44 Rated 4 out of 5 stars

As others have noted, this extension is currently not functional due to a change to the JavaScript functionality in Firefox 44. This was a "breaking change" that was expected to impact many addons, but needed to be done at some point.

Github user @InternalError503 has produced a patch for the breakage in about:addons-memory under Firefox 44+, and submitted it on github. There's no word yet from Nils (the author) about when or if a new version of the addon might be released with this fix, but it's only been a few days:

Doesn't work after Firefox 44 Rated 5 out of 5 stars

I used this extension for some time, it really was very useful as it gave the user a real sense of the use of computer resources, especially RAM.

However, from version 44 crashed, displaying the following message when trying to access about: addons-memory in the address bar: "The address is not valid. The URL is not valid and can not be loaded".

It seems to me that the extension was abandoned by the developer as it is for more than one year without updating.

If it were possible, it would be good that the author actualize it to solve the problem and again allow their use. But I do think it very unlikely.

Firefox update 44.0 breaks this addon. Rated 4 out of 5 stars

I can't find the page now, and if I directly enter about:addons-memory in the address bar, FF gives an "address not vaild" error.

with Firefox 44 does not work

Nice! Works as expected. Rated 5 out of 5 stars

As the dev said, the purpose of this add-on is to check whether an add-on behaves out of the ordinary. As long as everything works as expected (eg. nothing consumes more memory than adblock) then disable the add-on and be happy! Otherwise disable any potentially offending add-on and be happy! Kind of like the Extension Defender works.

Works in FF 43.02 as far as it can. Rated 5 out of 5 stars

Does what it claims except it may not show all the load due to processes. Paste about:addons-memory in address bar and hit Enter.

But what is more needed is an ext. that will show the cpu load for each ext and each tab. There is one for the memory use of each tab. but not cpu.

Doesn't Work Rated 1 out of 5 stars

Shows that Firefox and installed add-ons are using far less memory than they actually are.
You'll just have to check memory usage the old fashioned way:
Disable all add-ons & restart Firefox, then open Task Manager (ctrl+alt+del) and monitor the memory usage of firefox.exe as you enable your add-ons one-by-one (I recommend restarting Firefox after enabling each add-on, even if the add-on doesn't require a restart).

Rated 3 out of 5 stars

The idea is very fine and it looks good on the page, but why does it always show only about 25-30% of the memory reported by the task manager? I can see no point using it as it is.

Slows Download Speeds Immensely! I'm Glad it Can be Enabled/Disabled without a Restart Rated 3 out of 5 stars

This add-on is nice, but it's kind of annoying having to disable it when I'm not using it, as it slows my download speed so much. If I had to restart Firefox every time I wanted to use this add-on, I would have given it a one star review.

Eats Download speed on wired internet Rated 1 out of 5 stars

After troubleshooting with Time Warner discovered it was only Firefox that was eating 15Mb/s speed. Adding Add-ons back one by one discovered it was this add-on that was the problem. Now I have gone from 11.38 Mb/s back to 32.00+ Mb/s for my wired Arris modem/router. As this computer was a direct connect to the Internet without a firewall (for testing).
Either the code is not working or it has a hitchhiker with it?
Testing was done with a complete restart for each Add-On

Does not show the real difference between all enabled and all disabled add-ons Rated 1 out of 5 stars

I have installed about 20 add-ons and Firefox uses up to 300MB on startup. If I disable all add-ons it is around 140MB. This add-on unfortunately tells me nothing about these 160MB difference.

Very helpful Rated 5 out of 5 stars

Finally I can see clearly which add-on uses how much memory.
