Using openSuse 13.1 with KDE and FF 25.0

In my bashrc -- both for root and user -- I use

xset b off

to disable the "beep on error" for all programs. FF seems to be the only one to ignore this, which is quite a nuisance as I do work frequently in a library where silence is imperiative. Using earplugs every time i search a website (strg-F) and the word is not found the "beep on error" -- always on full blast -- almost blows my brains out.

Is there an (advanced) FF setting I have overlooked?

Open in Firefox:

Search for:


and set the value to: false

Then restart Firefox.

Use the alsamixer command. Hit F6, select your sound card. Use right arrow to navigate to the Beep bar. Either hold the down arrow until it is at zero or just hit the number 0.

Also, maybe you want Auto-Mute enabled. It's hard to tell. This will make it so you can have your laptop speakers at 0 and then plug in earbuds/headphones and they will have sound at a different setting. The disable of beep will still carryover, however.

  • Ecept the normal sound card, there is Console Audio Control, and I can't change the volume of it, even with sudo. – lolesque May 28 '16 at 9:17

To prevent any beep, sudo rmmod pcspkr will remove the kernel module that makes beep.

Writing blacklist pcspkr in /etc/modprobe.d/blacklist will prevent the module for being loaded again.
