Firefox, by default, makes an annoying sound everytime you type an additional letter in the “Find” field which it cannot find. A quick trip to about:config will easily resolve this problem.
Type about:config into the URL bar and in the Filter, type the following:
accessibility.typeaheadfind.enablesound
One entry should show up, and the value should by default be true. Double click it to change the value to false. Restart your browser, and changes have been applied.
Thank you thank you thank you!
I have been looking for this for awhile now!!!!
