Hi

It is not possible to change the sort order, but the default in Firefox for Android is to have the most recent at the top of the list and later history further down.

History on Android is not sorted in the order in which I've visited the websites, instead some websites are added while others are not, and websites are often grouped together.

The people who answer questions here, for the most part, are other users volunteering their time (like me), not Mozilla employees or developers. If you want to leave feedback for developers, you can go to the Firefox Help menu and select either Share ideas and feedback… or Submit feedback…, depending on your Firefox version. Alternatively, you can use this link. Your feedback gets collected by a team of people who read it and gather data about the most common issues.

You can also file a bug report or feature request. See File a bug report or feature request for Mozilla products for details.
