Description of problem:
After installing the newest "firefox 17.0.1" VirtualBox 4.1 (i don't have the package now) or 4.2 (VirtualBox-4.2-4.2.4_81684_fedora16-1.i686) does not work, and I "feel" that K3B (k3b-2.0.2-5.fc16.i686) and QGIS 1.7.4 (qgis-1.7.4-1.fc16.i686) sometimes hangs, when they are "working hard". I dont use KDE, but it's maybe problem with Qt programs after installing the newest "firefox 17.0.1".
After "yum remove firefox", "yum remove xulrunner" the problem still appeared.
With the newest "firefox 17.0.1" came nspr and nss like below:
Version-Release number of selected component (if applicable):
I've downgraded those to the last, what I had before:
...and problems disapeared.
After that I've installed Firefox from original Mozilla site - still no problems. I use the newest version of VirtualBox, like You see. I can't use the newest QGIS, becouse it has errors (not technical, but essential errors).
I didn't test with VirtualBox as KVM is what we ship on Fedora. I understand that VirtualBox may be your only viable option with older systems. On older i686-based systems without the hardware support for virtualization and VirtualBox may be the only way.
An update to 3.14 should appear in f16 updates-testing in a few days. The update set you were using, as explained in the notes, was intended to be a short-lived set for bootstrapping your system to prevent any possible conflicts when updating nss/nss-softokn/nss-util to 3.14. I had run into some install conflicts while testing as some headers moved around and ended in different -devel packages causing such conflicts. I pushed that set as a precautionary update to spare folks any pains. Additional testing suggests it may not be absolutely needed. The previous set would have been okay.
If you prefer to remain on the 3.13 line then the one with nss-3.13.3 you tried that worked for you is not the latest. The set just before the one where had problems using is 3.13.6 but it has -1 instead of -2. You can get it from https://admin.fedoraproject.org/updates/FEDORA-2012-15556/nss-util-3.13.6-1.fc16,nss-softokn-3.13.6-1.fc16,nss-3.13.6-1.fc16.
I wonder if it makes a difference.
nss 3.14 for f16 should be showing up in a day or two and it's available now from https://admin.fedoraproject.org/updates/nss-util-3.14-1.fc16,nss-softokn-3.14-5.fc16,nss-3.14-7.fc16.
This message is a reminder that Fedora 16 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 16. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '16'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 16's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 16 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged to click on
"Clone This Bug" and open it against that version of Fedora.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
