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.

IMPORTANT: 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, only new versions of Firefox (147 onwards) fully implement the Navigation API, so in older versions it's impossible to know if Back or Forward are really possible, meaning the corresponding arrows will show up on every site.

PERMISSIONS: Swipe Navigator requests permission to run on all websites because gesture detection happens inside each page. This allows the extension to recognize edge swipes and show visual feedback, then trigger browser back/forward navigation. The extension is designed for gesture handling only, not for collecting passwords, form entries, or browsing content.
