Since the recent FF update, the one addon I had for randomly-loading up a gif for every new tab got deprecated.

Sad stuff, but this addon does the job perfectly fine as well.

I didn't need links or URLs for my new tabs anyway so I just turned the shortcuts off. What I needed was something random every time I opened a new tab, and this addon fills in that niche gap for me perfectly well. Now I can have nice random gifs of animu grils and the occasional rekt and cute puppies.

Unfortunately, local file support doesn't work for your image choices. The HFS solution provided by the dev seems like a great idea, but I found that making an imgur album and dumping all your stills and gifs in it seemed to be a better choice. Sad that the images only work if you're online (no proper way of making local images work besides mentioned HFS workaround), but considering I'm almost-always in a place with a decent-enough connection, it's not so bad!

To dev: I wouldn't mind dropping a dollar if you got local file support for images! :D
