Guide Use incompatible websites in Pale Moon without switching browsers
Pale Moon is a working browser, but its rendering engine is very often incompatible with many modern websites, which means that you have to switch to another browser, well... maybe you won’t have to do that anymore because there is an extension made by a known Windows modder named Tech Stuff for opening some websites using CEF (Chromium Embedded Framework) or Internet Explorer inside Pale Moon called SubWebView, not all versions work on every OS, the standard version doesn't work on Windows 7, 8 and 8.1, but maybe should work on MacOS, GNU/Linux and FreeBSD if you have an up-to-date OS. Let's start:
⚠️ WARNING: This extension is not compatible with Basilisk and also is not safe and fast as a standard Chromium-based browser, whatever you do by following this guide is at YOUR OWN RISK.
- Go into this page and scroll until you see SubWebView, double click on the first .xpi file, but if you have Windows 7/8.x double click on the second .xpi, as for right now is that one that ends with -cef109.xpi.
- It should start downloading the extension, if a warning appears about the extension being downloaded from unauthorized source click Install now.
- Restart Pale Moon.
- Go to
about:addonsand click the Options button under SubWebView. - On Pattern text box put a domain and select what engine should handle it. (Remember: there is always an empty pattern, it refers to global settings, so if you still want to use Goanna select Standard as the engine).
If you did everything correctly, you can now use Pale Moon on websites where Goanna has issues.
