Firefox 34.0 Linux autocomplete address bar issues. How to cure?

Question

Mozilla Firefox

Good afternoon!
Recently there was a problem with the address bar autocomplete in the beloved fox.
For example, after entering www.google.ru, it redirects to www.google.ru/cgi-bin/luci (the error occurred after experimenting with iptables on a router under dd-wrt, as can be seen from the url).
The problem is not only with Google, but also with several other sites.
Tell me how you can cure?

Answer 1

Hm. Clearing the cache helped.
My apologies for distracting anyone.
