When Firefox is on, and I shut down or reboot my PC directly without closing Firefox, it shows a problem. When I click the '''restore session'' or '''start new session''' option, it takes some time to load the webpage. Sometimes, it takes 3-4 minutes to establish a connection. After resetting all data from Firefox, it fixes, but then it gets slow from time to time again. However, it is a problem to reset all the data regularly.
