Hi Roy,

You can set Firefox as your default browser in its settings.

Open the Firefox menu, select Settings, then General. Under the Startup section, click Make Default. If Firefox is already set as your default browser but links still open elsewhere, you may need to check your operating system's default app settings as well.

You can find the full instructions here: https://support.mozilla.org/en-US/kb/make-firefox-your-default-browser

Which operating system are you using: Windows, macOS or Linux? If Firefox keeps losing its default status, that information will help us narrow down the cause.

Or since you appear to be using the Firefox web browser for Android see https://support.mozilla.org/en-US/kb/make-firefox-default-browser-android
