| 6 // Test Summary: | |
| 7 // 1. Open about:sessionrestore where formdata is a JS object, not a string | |
| 8 // 1a. Check that #sessionData on the page is readable after JSON.parse (skipped, checking formdata is sufficient) | |
| 9 // 1b. Check that there are no backslashes in the formdata | |
| 10 // 1c. Check that formdata doesn't require JSON.parse | |
| 11 // | |
| 12 // 2. Use the current state (currently about:sessionrestore with data) and then open that in a new instance of about:sessionrestore | |
| 13 // 2a. Check that there are no backslashes in the formdata | |
| 14 // 2b. Check that formdata doesn't require JSON.parse | |
| 15 // | |
| 16 // 3. [backwards compat] Use a stringified state as formdata when opening about:sessionrestore | |
| 17 // 3a. Make sure there are nodes in the tree on about:sessionrestore (skipped, checking formdata is sufficient) | |
| 18 // 3b. Check that there are no backslashes in the formdata | |
| 19 // 3c. Check that formdata doesn't require JSON.parse | |
