Specific Website Tips¶

Websites With Multiple Domains¶

Some websites use multiple domains, for example for Single Sign-on (SSO). This is normally not a problem, but if you have enabled the "Open out-of-scope URLs in a default browser" option, those functionalities may not work properly (for example, you may not be able to log in), as any out-of-scope domains will be redirected to the default browser. For those websites, you will have to additionally use the "Domains always allowed to be opened in the app browser" option to set domains that should always be opened in the app browser.

We maintain a list of recommended values for some popular websites and services where this is needed. If you know another popular website that is not already listed, or would like to change something in this list, please create a new issue or PR.

Websites With Invalid Manifests¶

Some websites cannot be installed with the manifest enabled because their manifests are invalid or do not follow the specifications properly. To install such websites, you can try disabling the use of manifest for determining the app properties.

We maintain a list of known websites with those problems. If you have a problem installing another website that is not on this list, please create a new issue or PR. If you believe that a website on this list follows the specifications, but cannot be installed because of a bug in PWAsForFirefox, please create a new issue.
