[SOLVED] Cannot reopen Firefox

TSquaredF · 09-26-2009, 02:26 PM

I am having problems when I close Firefox, then attempt to open it later, without logging out of KDE. I get a dialog box that states

Quote:

Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.

I issue

Code:

killall /usr/lib64/firefox-3.5.3/firefox-bin

then all works OK. I am using Slackware64-13.0 (no Multilib on this machine), stock KDE & most recent Firefox, however the same thing occurred with FF-3.5.2. This is not happening on my laptop, where I have an almost identical install. It's not a major deal, but is a hassle to always have to open a terminal & kill FF. Can somebody tell me what I can do?
Regards,
Bill

Hi -

As you know, this *shouldn't* be occurring.

There are a number of (completely different!) reasons why it *might* be occurring.

Here's a link with a number of good ideas (many Windows-related, but many also likely candidates for your Slackware/Firefox):

I had a similar problem when using gtk-qt-engine.

Thanks for the link. I didn't know about the lock files & the rest of the thread is interesting.

mattydee: Thanks. That was my solution. I have no idea why gtk-qt-engine is interfering with FF, but removing it solved my problem.

Hi -

You can read more about the KDE4 gtk-qt-engine here:

This appears to be the bottom line:

Sadly, gtk-qt-engine is a quite broken piece of software and has been removed from distribution. (See bug 404930)
Unfortunately this means that the large number of bugs will not be seeing fixes.

For now, the best integration option for KDE is the QtCurve style, (gtk2-engines-qtcurve) which offers a theme quite similar to the default Oxygen theme. The configuration module for gtk-qt-engine has been salvaged and is now living in the kcm-gtk package, which will be available and installed by default in Kubuntu 9.10.

Thanks for understanding. This package tried its best, but in the end did not live up to the standards required by anybody who doesn't like looking at a broken Oxygen imitation.

Your welcome. I use qtcurve-gtk2 (available at slackbuilds) as a replacement and am happy with it.

edit: Just saw the quote by paulsm4. Anyway, I second the recommendation for qtcurve.
