Firefox не может загрузить страницу в 16,04

Моя система запускает Ubuntu 16.04 LTS, и я сталкивался со странной проблемой с тех пор, как я начал использовать его. Много раз, когда я пытаюсь открыть веб-сайт на своем браузере (Firefox), мне говорят "Сервер, Не Найденный" и только после обновления страницы многочисленные времена, которые я могу получить к веб-странице. Эта проблема всегда не происходит или для каждого веб-сайта одновременно, но это, действительно оказывается, достаточно часто раздражает ад из меня.

Кто-либо может пролить какой-либо свет на это?

PS. Эта проблема, кажется, уникальна для 16,04. Я использую соединение LAN, и ни у кого больше использующего это соединение нет этой проблемы (ни один из них не работает 16.04 хотя). Кроме того, я имел 12.04 прежде в той же системе, и она хорошо работала.
