CentOS 7 Firefox display

math.qe · 02-16-2020, 07:49 AM

Hi everyone,

I'm totally new with Linux and I do have an issue with opening a web browser (firefox).

In the moment I double click on the firefox' icon nothing is displayed. I didn't find some specific logs in /var/log.

Right now to only one way I can open the browser is using:

#ssh -X hostname firefox

But I'd like to figure out what's the problem to open the browser by simply clicking on the icon.

Any help will be much appreciated.

Thank you in advance!

HOW did you install Mozilla Firefox?
What version have you installed?
Which CentOS desktop are you running? (The default is fine, but tell us that if it is so.)

Hey,

Thanks for the quick reply!

Well, I didn't install anything specific. Just installed the KDE desktop, but the same is happening with GNOME.
No specific installation over the cli, I think it's already installed. Not sure if I can paste a picture here, but in the moment I double click on the firefox icon it looks that it starts loading .. and then just stops.

If this can help:

[addie@addie ~]$ firefox -v
Failed to open connection to "session" message bus: Unable to autolaunch a dbus-daemon without a $DISPLAY for X11
Running without a11y support!
Mozilla Firefox 68.4.1esr

That tells us quite a bit, actually. It appears to me the command portion of the shortcut was malformed. (Guessing somewhat here) It is just possible that you could fix it, and that is what I would do on my machine. The quicker fix may be to totally uninstall FireFox from the machine, Purge the settings and ensure that the shortcut is gone from the desktop, then install Firefox clean. My thought is that it does not matter if it is wrong now, as long as that install process builds a correct shortcut on your desktop you are good.

And that makes the software do all of the heavy listing, so you do not have to research the proper shortcut settings and possibly still fail. We can come back to that option if the install fails to correct the issue.

in your home folder is a folder called " Desktop"

in that folder is a file called "firefox.desktop"

this is what should be in it when you open the file in "kate"

Code:

#!/usr/bin/env xdg-open
[Desktop Entry]
Categories=Network;WebBrowser;GTK;
Encoding=UTF-8
Name=Firefox
GenericName=Web Browser
Comment=Web Browser
TryExec=firefox
Exec=firefox %u
Icon=firefox
Terminal=false
StartupNotify=true
MimeType=text/html;text/xml;application/xhtml+xml;application/vnd.mozilla.xul+xml;text/mml;application/x-xpinstall;x-scheme-handler/http;x-scheme-handler/https;x-scheme-handler/ftp;
Type=Application

Actions=PrivateBrowsing;

[Desktop Action PrivateBrowsing]
Name=New Private Browsing Window
Exec=firefox --private-window %u

if yours is different then edit it to match mine

Thank you very much for the responses!

Currently it is working fine, without reinstalling it .. I will search for the "firefox.desktop" file and will compare it >> will share the outcomes as soon as I take a look.

Once again thanks a ton!
