Tor Browser 4.5.1-build1 is up at: https://people.torproject.org/~mikeperry/builds/4.5.1-build1/
This release updates us to the upcoming Firefox 31.7.0esr release, fixes a meek launch issue for Windows 7 users, fixes a NoScript UI update issue when switching security slider levels, fixes download and display issues with PDFs, relaxes our domain isolation to TLD instead of FQDN to reduce breakage with file download and other sites, and disables NoScript's clearclick protection (due to false positives with ReCaptcha and other sites).
The windows exe's are not yet signed with our DigiCert key.
