Firefox 技術支援討論區

I have different login forms on different sub domains so I always get a huge lists of different logins. and also I get my password for the basic auth from the web-server on my login form.

I also consider this as a security risk when different sub domains belong to different parties and I accidentally put my password into the wrong form.

Can I config Firefox the way that I get only passwords in the list that match the exact url or at least the (sub)domain?

Another Question As a Web-developer can I do something that my client don't experience such a mess (like giving the login form a special id so passwords are restricted do this particular form.

I've been making my own Firefox theme using the Firefox Color extension. I uploaded an image but I can't figure out how to show the image on the new tab screen. Setting the new tab page color to transparent only makes everything white. I know the image is uploaded correctly because I can see some of it in the toolbar and tab list. Is it possible to show the image on the new tab page?

I am using a Mac and have no idea what this is or how to turn it off, image attached it comes up down the bottom of the taskbar even when firefox is not running. Thanks
