Be sure to check out the NextPlease! User Guide at http://nextplease.mozdev.org/usage.html for information about how to customize NextPlease! for your browsing pleasure. It's very customizable and if a site doesn't work by default, there's a decent chance that you can get it to work fairly easily by adding a phrase or image using the context menu. Check the user guide for more info.
If you don't like the position of the toolbar buttons, you can use the Firefox customization dialog to drag them where you want, or to remove them.
If you find any bugs, or sites that just won't work, please log a bug at https://www.mozdev.org/bugs/enter_bug.cgi?product=nextplease, or send an e-mail to alexey.v.romanov on gmail.com
Don't just post the bug reports in reviews, since we won't be able to contact you in this case.
If you want to help with development, artwork, or localization, you are welcome. Please send email to the address above.
