Re: Why is " Ant Video Downloader 2.4.5" not compatible with FireFox 10.0.2, and will it ever be.
You can try to right-click on the + after the last tab, Customize and check if it's hidden behind another icon or inside the Customize Toolbar mini-window. Please see Customizing. You can also check the status and try the add-on's Options in Tools (Alt + T) > Add-ons > Extensions (on the left).
See the big green download button? DON'T click on that (it's for version 2.4.5)..
Instead, look underneath it, and see the fine print, which says:
"You can also try our Beta version of Ant [dot] com Video Downloader!"
Click on THAT.. (the actual words "Beta version" in the middle of that fine print).
You will be taken to a page where you can download Ant Video Downloader 184.108.40.206.
THAT one will work with your Firefox 10.0.2
Hopefully, Ant Video will SOON update their stuff, so that 220.127.116.11 is out of beta stage, and BECOMES the main download.. Until then, I hope I have helped you. Good luck.
