Vivaldi 7.5 browser update brings colored tab stacks and DNS over HTTPS

Just one day after Opera received an update with new translation tools and general improvements, its spiritual successor Vivaldi has released version 7.5. The Chromium-based browser, created by a team led by Opera co-founder Jon S. von Tetzchner, is rolling out a new build focused on usability, privacy, and customization.

The headline additions to Vivaldi 7.5 are colored Tab Stacks, a cleaned-up tab context menu, and new privacy controls including DNS over HTTPS. The update also includes a number of smaller fixes and UI tweaks that improve day-to-day use.

Tab Stacks have been part of the browser's lineup for years, allowing users to group related tabs into collapsible collections. The long-requested new feature now lets you assign a unique color to each stack, making it easier to organize everything from work tasks to travel research, and identify tabs at a glance. This will come in especially for heavy users juggling multiple projects. As someone who rarely has fewer than 50 tabs open at a time, it's a big help.

Vivaldi has also introduced a new dialog for editing browser Tab Stacks. Right-clicking on a stack brings up an Edit Stack option, where you can give the group a name and pick a custom color.

The tab context menu has been reorganized as well. This is the menu you see when you right-click a tab in the browser, and it now offers quicker access to essential functions like opening a new tab, stacking, or moving tabs between windows.

Browser refinements improve navigation and built-in tools

Behind the scenes, there are plenty of other improvements across the entire browser. The address bar has received tweaks to how suggestions are handled and how the dropdown behaves. Vivaldi’s built-in ad blocker now supports additional rule types like badfilter, strict3p, and strict1p.

For anyone who relies on built-in browser tools like bookmarks, notes, and mail, version 7.5 introduces smoother drag-and-drop behavior and visual polish. The mail and calendar apps inside the browser now handle invites more intuitively and thread conversations more reliably.

One of the more technical but important updates is support for defining a custom DNS provider within the browser. This includes DNS over HTTPS, which encrypts domain name queries to prevent third parties from seeing which websites you’re visiting.

Quick Commands, the power-user feature that lets you control the browser from a pop-up keyboard panel, now displays synced tabs and shows errors more clearly. The settings menu has also been cleaned up, making features like workspace rules and DNS inputs easier to find and configure.

On top of all that, Vivaldi 7.5 includes a broad set of bug fixes.
