How to open a browser in Safe Mode

Internet browsers

Some web browsers feature a Safe Mode that temporarily disables features that are not necessary to use the browser. If your browser is running slowly, or frequently crashes, Safe Mode may help you troubleshoot the problem.

In Safe Mode, any installed extensions are temporarily disabled. If the problem with your browser goes away in Safe Mode, one or more of your extensions might be causing the problem.

Tip

To disable extensions individually, or remove them completely, see: How to disable or remove browser extensions.
