I loved the firefox extention Super Drag and Go; unfortunately it is no longer being developed. Instead I found its replacement which does the job for me. Its called QuickDrag and allows me to do the following three jobs that I use often.
- select an URL ( e.g. https://awhan.wordpress.com ) and drag and drop it to load it in a new tab !!!
- select a text and drag and drop it to start a search in a new tab
- drag and drop images to download them
well that’s it what I use it for and I like it a lot 😀

Talking about URL and then giving an example – politically correct or underestimating the intelligence of the people reading your blog.
No dear … I am not underestimating the intelligence or awareness of the people reading my blog. I just assumed that it would be easy for those who are not familiar with the technical terms.
oh don’t forget to check the “Open clickable links in new tabs instead of searching or saving.”
that will allow you to simply drag drop links and open them in new tabs instead of searching for them… precisely what i want 🙂
