# Customization

As user, it is possible to override all options set by this project. Usually it
can be done in the preferences (which are now adaptive, so you can actually use
them on your phone).

To remove elements (e.g., the reload button, if you do not use it often) you
tap and hold the extensions Menu and select "Customize Toolbar".

If you don't like that the Firefox UI is moved to the bottom, or you don't like
the tabcounter, you can go to our custom `about:mobile` page and change things
to your liking.

Feel free to
[create an issue](https://gitlab.postmarketos.org/postmarketOS/mobile-config-firefox/-/issues)
if you run into problems. Or even better, attempt to fix the problem yourself
(see development instructions below) and submit a
[merge request](https://gitlab.postmarketos.org/postmarketOS/mobile-config-firefox/-/merge_requests).
