I am using Ubuntu18.04.2LFS.
I moved to another office, when I typed
firefox and searched, there is some errors. I can't search. I tried Google, but it doesn't work, too.
However, I can open the page like ask ubuntu.
In other words, I can open the link, but I can't search with firefox and google.
Any ideas? Is it about the wifi ? What can I do to make it working again?
