Description

[crosbow]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:37.0) Gecko/20100101 Firefox/37.0
Build ID: 20141226030205

Steps to reproduce:

nothing


Actual results:

suddenly firefox will use full downstream and i don't know what causes it.


Expected results:

firefox should have a process manager that will let me find out which site/addon/component causes this traffic.

Use the OS tools to log that.

Comment 2

[crosbow]

1. Google SafeBrowsing database update (Preferences → Security → Block reported…).
2. New tab page thumbnails: https://support.mozilla.org/en-US/kb/new-tab-page-show-hide-and-customize-top-sites#w_how-do-i-turn-the-new-tab-page-off

Open the regular toolbox, go to the settings, enable browser debugging and remote debugging, then open that menu again.

now that download happenend again and i was able to see that the toolbox is useless here:
1. the network manager doesnt capture that request because its already ongoing
2. the timing function only lists it as "function call" not giving any further details.

[Panos Astithas (he/him) [:past] (please ni?)]

Why don't you just use something like tcpdump or wireshark, like comment 1 suggested, to give us a hint about what kind of connections are happening? We may be able to explain to you what is going on.

The Network panel should help you with anything that doesn't happen before it opens.

[Jan Honza Odvarko [:Honza] (always need-info? me)]

The Network panel in the Browser Toolbox should help in this case, closing.
