Firefox high CPU usage: How to find out which addon is guilt

Post by Clemens.Ratte-Polle »

hi
FF runs on to high CPU when starting for 15 Minutes :(

Is there the possibility in the Inspector (CTRL+Shift+C) to find out CPU and memory usage for Addons ??
Why there is no extra tab for addons?

thx

It does not function by change the option afterwards :(
ok, i finally solved it in the User Control Panel - not easy to find.


Topic FF:
I just killed Firefox because it ran to hot and loud by 60% CPU usage... o_O
Only 1 empty Tab open but 2 "Sub-Processes" are running wild! >:(

Have you tried starting the program in Mozilla Safe Mode? http://kb.mozillazine.org/Safe_mode

Post your list of add-ons and maybe someone will know if it is one of those. And try out safe mode. Maybe it's something else causing it.

But here's the "usual" way to find out:
http://kb.mozillazine.org/Standard_diag ... ion_issues

But, no. There is no direct way to identify which one might be causing the problem. Sometimes it's a conflict between two extensions.

Here's the list of known troublemakers. Not sure how up to date it is in the quantum era.
http://kb.mozillazine.org/Problematic_extensions

Could also be caused by hardware acceleration. You could try turning that off.

You have to do trial and error with your add-ons, turning each one off and on, until you find the problematic one.

Hi Clemens.Ratte-Polle,
Just a little more on Firefox "Safe Mode."

Don't add any extensions or themes until it's working O.K.
If Firefox is O.K. in Safe Mode then it's an extension/theme...etc causing it.
Run Firefox in normal mode & disable them all. Re-start Firefox.
Enable each in turn, or by ½'s, re-starting Firefox each time, till the faulty extension is found.
Either update or un-install it.

When in Safe Mode...
* The status of plug-ins is not affected.
* Custom preferences are not affected.
* All extensions are disabled.
* The default theme is used, without a persona.
* userChrome.css and userContent.css are ignored.
* The JIT/Javascript compiler is disabled.
* The default toolbar layout is used.
* Hardware acceleration is disabled.

Moving this to Firefox Support...

Solved!! :)
It is possible to see the effect of deactivated Extensions at once - i did not know this.

Call in Firefox:
about:addons
then deactivated 5 in a row and looked for CPU-Usage.
Then activate them and deactivate the next 5 Addons beneath.

So i found systematically the guilty addon:

Video Downloader by Dirty Little Helpers
https://addons.mozilla.org/en-US/firefo ... nloader-1/

I will also post there my complain.

WHAT FF needs: Not only difficult memory about:memory display, also CPU live measurement.

thx a lot :)

you better stick with the german forum
https://www.camp-firefox.de/forum/viewt ... 1&t=124978

btw no reason to be rude to helpful hands.
if they suggest a new profile its better to follow that advice - you wont lose the old one.
a new profile indicates a profile caused or a system caused issue - its just testing methode.

nobody shall follow anybodies "nice advices" with no doubts.
To cite here the same case from another forum is... o_O Srry.
I will look and wait what other solutions will be suggestet and not follow the first one - what is never the best.
A new profile only would have found out what i meant before: An Addon runs Amok.
With it you can surround it, ok.
