The changes are good. . . Rated 4 out of 5 stars

Thank you for the changes to allow removal of the button from the addon bar and placing the red X button inside the text box. Just a tweak or two as suggestions. . . the red X appears a couple of pixels too high in the text box - can it be centered vertically? Also, on some text boxes, the red X is not right next to the right side border but quite a distance too far left. On other boxes, the X is correctly placed next to the right side border. I don't know why this is only affecting some text boxes and not others.

This review is for a previous version of the add-on (1.8.1-signed.1-signed).  This user has other reviews of this add-on.

Thanks for your suggestions. I updated extension to show red X in input text box for all kinds of text fields. Please let me know if it does not show red X correctly on any input text field. I also fixed the bug of status bar icon settings. Now settings are preserved during close and reopen of Firefox. New version will be available to download as soon as FF approves it.
