Tried all of your suggestions and still receive "Unable to connect" when using ANY search engine.
Cannot use any search engine in FF 40.0.3 on Macbook Pro model 9,2 with OS 10.8.5. Receive "Unable to connect" message when attempting to use a search engine. Websites other than Mozilla and search engines connect fine. FireFox 40.0.3 on a different Mac works fine with no problems.
In addition, I cannot access the FF "Get Add-Ons" page or the Mozilla home page. Search engines will not connect from either the search bar or their home page. Problem just started. I had previously updated to, and have been using, FF 40.0.3 without problem when it was issued. Attempted solutions have included FF refresh, run FF in safe mode, run with all plug-ins disabled, disabled hardware graphics acceleration. None of these corrected the problem.

Had already tried your suggestions without success but did them again to be sure. No success. However, I did some other exploring on my own and discovered that IPv6 was set to "Local Link Only" in my router. I reset that to "Automatic", the router reset to update this, and my problem was solved. So it was either the IPv6 setting (not likely) or the router reset (likely) that solved the problem, or it was your suggestions which I attempted and did not work, COMBINED with the router reset that solved the problem (very possible).
Thanks for the input!
