A new version of alternative web browser Vivaldi improves window and tab handling, and includes a new window management sidebar panel. Download management is also improved: downloads can now be resumed after interruption. Bookmark handling is slightly improved, although in my opinion there’s still more work to be done in that area.
A variety of bugs were fixed in Vivaldi 1.13 as well. This Vivaldi blog post lists all the significant changes in Vivaldi 1.13.
Vivaldi remains an excellent alternative to the more popular browsers. Although it has some quirks, it also has features not found in other browsers, such as tab stacking. If you’re looking for a different browser, Vivaldi is worth checking out.
