What kind of sound is this?

Is it one of the Windows sounds?

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).

• Do NOT click the Reset button on the Safe Mode start window.

its like a muffled thunder sound or similar not a windows sound i have never hear it before its horrible

Did you try Safe Mode in case it is caused by an extension?

got it it was the culprit gmail manager 6.5.2

i have another issue some websites like this one i saved the username and password however it wont auto load any reasons why?

when i enter the username and password it does not prompt me to save as its already in my saved username and password list suggestions?

That website might be using autocomplete=off to prevent Firefox from saving and auto-filling the name and password.

You can remove autocomplete=off with a bookmarklet to make Firefox save names and passwords and other form data.

You will have to double-click the name field to get a drop-down list where you can select the name in such a case.
If the list doesn't open then try to remove the focus from the input field by clicking elsewhere or use the Tab key and Shift+tab.

the annoying sound is coming from no scripts not from the gmail manager how do i get rid of it i like no scripts hate the sound!
