Package: iceweasel Version: 31.6.0esr-1 Severity: important --- Please enter the report below this line. ---
It is well known that iceweasel / firefox often fully uses one CPU core when a page is being displayed (see all the bug reports here and upstream). I am used to it. However, recently, I see it fully use a CPU core and continuing to do so, even when I close all tabs or close it. To reproduce: Start iceweasel, open some pages, wait for some time uintil it starts fully using a CPU core, then close all tabs. It still fully uses a core. When I close it (using the 'x' from the window manager), the process still fully uses a core. Sending a TERM signal using kill works though. --- System information. --- Architecture: amd64 Kernel: Linux 3.16.0-4-amd64 Debian Release: 8.0 500 unstable ftp.de.debian.org 500 testing ftp.de.debian.org 1 experimental ftp.de.debian.org --- Package information. --- Depends (Version) | Installed ===============================================-+-=================== libasound2 (>= 1.0.16) | libatk1.0-0 (>= 1.12.4) | libc6 (>= 2.17) | libcairo2 (>= 1.2.4) | libdbus-1-3 (>= 1.0.2) | libdbus-glib-1-2 (>= 0.78) | libevent-2.0-5 (>= 2.0.10-stable) | libffi6 (>= 3.0.4) | libfontconfig1 (>= 2.11) | libfreetype6 (>= 2.2.1) | libgcc1 (>= 1:4.1.1) | libgdk-pixbuf2.0-0 (>= 2.22.0) | libglib2.0-0 (>= 2.37.3) | libgtk2.0-0 (>= 2.24.0) | libhunspell-1.3-0 (>= 1.3.3) | libnspr4 (>= 2:4.10.3) | libnss3 (>= 2:3.16) | libpango-1.0-0 (>= 1.14.0) | libsqlite3-0 (>= 3.7.12-1~) | libstartup-notification0 (>= 0.8) | libstdc++6 (>= 4.9) | libvpx1 (>= 1.3.0) | libx11-6 | libxext6 | libxrender1 | libxt6 | zlib1g (>= 1:1.2.0) | fontconfig | procps | debianutils (>= 1.16) | Package's Recommends field is empty.
