Hello, I used some add-on that are not available anymore, since FF changes. I need help to find extensions that could help me. - Image Toolbar helped me to download images from websites that don"t allow to download, specially when a click on the image gives the next image and/or the right clic is not available. "Image toolbar" didn't do it everytimes, but it worked often. - Tab mix plus is not available. I need the X on the right of the tab line. And I need to re-open closed tabs by double-clicking.

Thank you !
