Hi

I have had a look into this and have found this article that will walk you through choosing which elements to Sync between your copies for Firefox. You may need to deselect the option to include your browsing history when you use Sync.

I hope this helps, but if not, please come back here and we will look into a different solution for you.

Well, it's not the best solution, but it looks like it'll have to do.

See, I want history to synchronize between my devices, but I like to clear my history once a month. It'd be awesome if there was a way to get Firefox Sync to synchronize the deleted browsing history, instead of just re-downloading it.

Google Chrome handles this a lot better, but I like Firefox much better.
