Firefox 18.0.1 does not work on Mac OS 10.7.5


Dear colleagues,

Lately my firefox 18.0 got automatically updated to 18.0.1. Since then I'm not able to load any page, firefox starts normally, but it can not load any page (the load animation goes on forever). Version 18.0 was working perfectly untill the update. I tried to reset firefox completely (deleting all folders in Application Support, removing everything related to it), I tried reinstalling and nothing seems to help. I'm using Mac OS X 10.7.5, I have all latest updates insalled, I don't use any proxies, and the only firewall I have - system firewall is set up to allow firefox to connect. If I delete everything and install back the old version 18.0 I have no problem but as soon as version 18.0.1 is installed it can't load any web page. I'll appreciate any support on that! Thank you in Advance!

Try to disable IPv6, also check for other solutions.

You can try to reset (power off/on) the router.

You can also try to uninstall (trash) and reinstall Firefox.

You can find the latest Firefox release in all languages and for all Operating Systems here:
