The latest Release is Firefox '''31.0''' as the only way you would get updated to the current Beta build which is Firefox 32.0'''b2''' (b2 = Beta 2 as there can be say six to twelve Betas) build is if you were on the Beta channel due to having installed a Beta build and continued using it since. If the Firefox 31.0 you installed is updating to 32.0b2 then the 31.0 you installed was a Beta build (make sure the file name did not have say 31.0'''b'''# as there were nine Betas) and not the Firefox '''31.0''' Release say from mozilla.org or https://www.mozilla.org/en-US/firefox/all/ The typical reason for a new version (on Windows) not being able to connect after a new major version Firefox update or install is usually due to a software Firewall blocking the new .exe yet it may stll have the previous version allowed. *https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can *https://support.mozilla.org/en-US/kb/configure-firewalls-so-firefox-can-access-internet
