What's new in this version:

Web Compatibility:
- Attempted compatibility improvements for Chase and Discord by adjusting how Waterfox presents itself to the site
- These changes are compatibility workarounds rather than fixes for a technical limitation in Waterfox. Some sites appear to rely on user agent checks to decide whether a browser is supported, so Waterfox now makes a better effort to identify itself in a way those checks will accept. There is no guarantee these fixes will work, but I have not found a technical reason why these websites would not work that hasn't already been implemented in Waterfox.

Site Data:
- Added a new Always store cookies/data for this site toggle to the site information panel. This gives you a quick way to let a trusted site keep its cookies and site data, which can help when a site keeps forgetting logins, preferences, or other saved state because of stricter cookie settings. Thanks to Defelo for the PR, and to LibreWolf for developing the original patch.

Ad Blocker:
The built-in blocker has received another round of reliability and performance improvements:
- Modern filter lists should now be handled more reliably
- Some site specific ad-blocking fixes should now be picked up correctly instead of being ignored or misread
- Pages loaded immediately after opening Waterfox should be less likely to briefly show ads or annoyances before the blocker catches up
- The blocker now does a little less background work when a page starts loading
- This will hopefully enable greater compatibility with websites like YouTube, working around their anti-adblock messages
