Bugzilla

Hello, thank you for the bug report! 
Unfortunately I could not reproduce your issue. Would you be so kind as to answer a few questions so we can investigate this further?
- If possible, could you please detail the STR? 
- Do you mean that the URL’s are not removed at all if using the Shift+Delete key combination, or are removed from one tab but reappear in the next? 
- Does this issue happen with a new profile? Here is a link on how to create one: https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles
- Does this issue happen with latest nightly? Here is a link from where you can download it: https://www.mozilla.org/en-US/firefox/channel/desktop/
- Does this issue happen when Firefox is in Troubleshoot Mode? Here’s a link on how to enable it: https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode#w_how-to-start-firefox-in-troubleshoot-mode

Any additional information you can provide would be very useful.
