I was checking the Unanswered section in SO. Then I clicked java tag to get Java related questions. The url was
https://stackoverflow.com/unanswered/tagged/java
Then I clicked on javascript tag. The URL became
https://stackoverflow.com/unanswered/tagged/javascript
This happened today only. Yesterday and all when I click another tag, the URL would append the tag. ie,
https://stackoverflow.com/unanswered/tagged/java+javascript
Why its happening? Earlier was easy. Now for more tags, we need to type URL, instead of clicking each tag?
