Go step by step and test.
1. Quit Safari, launch Safari holding the Shift key down.

It also does a basic check of your startup disk, similar to using First Aid in Disk Utility.
And it deletes some system caches, including font caches and
the kernel cache, which are automatically created again as needed.
3. Clear History
