Simple Swipe Navigator od usemoslinux

Swipe Navigator makes browsing more fluid and natural by adding gesture-based navigation to Firefox, as seen on other popular mobile browsers, like Brave. This extension allows you to:

• Swipe right-to-left from the left edge to go back
• Swipe left-to-right from the right edge to go forward

As you swipe, a subtle animated icon appears to let you know which action is about to be triggered: an orange back arrow, or a forward arrow—all styled to stay visible and separate from page content.

Designed with mobile devices in mind, but also works great on touch-enabled laptops and tablets. Lightweight, responsive, and works across all websites.

No settings. No ads. Just smooth gesture navigation.

Note: Due to Firefox security restrictions, swipe gestures do not work on addons.mozilla.org and all mozilla.org pages, Reader Mode pages, or internal about: pages.

Also, due to Firefox's lack of implementation of the Navigation API, it's impossible to know if Back or Forward are really possible, so the corresponding arrows will show up on every site. In those cases, swiping will do nothing.
