Hi yinguozhi,

Thanks for reporting this bug.

In which version of Firefox did this happen? Were you browsing any site in particular? how many tabs were opened?

Please try the following:

• Download the latest version of Firefox Nightly from here https://nightly.mozilla.org/ and retest the problem.

• If you still have the issue, create a new profile, you have the steps here: https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles?redirectlocale=en-US&redirectslug=Managing-profiles#w_starting-the-profile-manager
