Open "Link to External Url" in new tab by default in TYPO3
In TYPO3 you can create a pages of the type "Link to External Url". Those pages appear just like normal pages in the navigation, but link to the absolute url given configured for the page. Links to those external pages are generated just like any link to a TYPO3-internal page. This leads to the kind of counter-intuitive behavior that these pages are opened in the same browser tab even if config.extTarget = _blank
is set.
I was looking for a solution to open all external pages in a new tab. The bad news is: There is no built-in way to do that, but depending on your needs there are some fixes. Here are five solutions I found in order of increasing complexity.
