What's new in this version:

- All security and stability fixes from Firefox ESR 45.9.0
- Further improvements to the efficiency of machine code generated by our custom PowerPC JavaScript JIT
- The font blacklist has been updated and is now able to block incompatible data-URL fonts, fixing bad font errors on most pages on Medium and most sites using Medium-based blog assets
- An issue preventing permanently changing the default search engine should now be repaired. However, certain users may need to create a new profile for the setting to stick in the future. This should only be necessary once. If you require assistance with this, please open a ticket at Tenderapp
- Further improvements to font rendering speed
- HTML5-based geolocation should now properly invoke the Mozilla Location Service
- Certain runtime internal function calls are now more efficient
