Since I updated Firefox, it seems my internet connectivity in that browser has dropped. I can Google things (not in the URL box, but in the Google box) perfectly, with the exception that sometimes the link clicked from Google doesn't load. However, I cannot actually visit an individual site by entering the URL. If I directly enter the URL, it comes up with a 404 error, site not found. If I try to navigate to some pages from a Google, it comes up with a connectivity problem page. I would really like to be able to use my Firefox again. In the meantime, I'll have to use Google Chrome.

Try clearing Firefox's cookies and cache

Do these steps and then reload the website you're having trouble with.

  • Click the menu button New Fx Menu , choose History and select Clear Recent History....
  • In the Time Range to clear: drop-down, select Everything.
  • Click the arrow next to Details to display the list of items that can be cleared.
  • Select both Cookies and Cache.
  • Click Clear Now.


Moreover, normally such issues are caused by a firewall/security software which doesn't recognize & therefore blocks new firefox versions:Fix problems connecting to websites after updating Firefox

It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full, unrestricted, access to internet for Firefox and the plugin-container process and the updater process.
