Firefox addons for Android do not have the ability to modify the history because the History WebExtensions API is incompatible until now. I'm referring to this API: History.
I really want my browser to delete history older than X days unfortunately Firefox doesn't do it. This is one of the most requested idea. If Mozilla isn't able to do this feature request, can they at least enable the History API so that addons can fulfill this request? The History Cleaner addon could do this if only it had access to the History API.
