after an upgrade from v7.6 to v8.7 and executing the upgrade wizard every link in content and navigation has a target="_blank".

Can anybody help me?

Best regards

In your Typoscript:

To open internal links in the same window:
- either set config.intTarget = _self (TYPO3 11 documentation)
- or completely remove config.intTarget, as _self is the default <a> target attribute value
To open external links in a new tab/window:
- set config.extTarget = _blank (TYPO3 11 documentation)
