As of Firefox 152.0, the browser no longer defaults to directing to https://start.fedoraproject.org. Instead, Firefox simply sets the URL to `data:text/plain,browser.startup.homepage=https://start.fedoraproject.org/` and renders the plain text string:
```
browser.startup.homepage=https://start.fedoraproject.org/
```
Note: This is not the same bug as some users have experienced in the past where the Fedora Start page is overwriting their custom homepage preference. This is a separate (possibly related, possibly not) issue where the Fedora's config no longer correctly sets the homepage.
Reproducible: Always
Steps to Reproduce:
1. Update to Firefox 152.0 on Fedora 44 without a custom homepage set prior
2. Restart
3. Open Firefox
Actual Results:
Page will render plain text config setting instead of loading the actual Fedora start page
Expected Results:
https://start.fedoraproject.org should be set as the URL and loaded instead of the text data literal.
