Short note: My previously unknown issue occurs in connection with the e-Browser v131.0.6778.140
e-Browser
When entering the characters . (= dot), e.g. e.foundation or slash (“/” ) in the URL search field, the entire content in the search field is deleted. This means that e.foundation cannot be typed in completely and the URL cannot be called up. The alternatively installed FOSS Browers from the F-Droid Store, on the other hand, does not have this problem and works perfectly.
