Feedback and FAQ

Before sending feedback, it may be helpful to read these FAQ:

1. Help! Websites look weird / squished to the left ever since I installed this extension!

• I have had some issues with the extension's CSS overwriting websites' CSS, and hopefully all those issues are fixed now. If not, please let me know and I'll fix it soon. For now though, you can just disable the extension when it's not needed and everything will be fine.

2. How do I know my instrument's A4 frequency?

• Go to this site, (which is a tuner, Google will warn you about a redirect) and play the key/string/whatever that is supposed to be A4 on your instrument. Finding that note varies by instrument so I'd just recommend a quick google of "how to play A4 on the trombone" or figure out how to play middle C if that's easier.

A4 is the A above middle C, see the image below.
