Hover Zoom+
Version: 1.0.180 Web: https://github.com/extesy/hoverzoom
Many of us spend most of our screen time using a web browser. Why not enhance the browsing experience with some open source browser extensions? This time we’ll address the issue of content scaling, which seems to be a frequent complaint from high DPI screen users. Even if the UI fonts and other desktop elements scale up correctly, the content rendered by web browsers is a different story.
Instead of zooming in and out the entire web page manually, why not bring select images closer on demand? That’s what the Hover Zoom+ extension does. Hover the mouse over any image on a web site and the extension will enlarge the image to its full size, or make it even larger if you increase the scaling factor in the extension’s settings. The enlarged image will always fit the page view and never exceed it, therefore the actual scaling factor may be lower for already large images.
Accessing Hover Zoom+’s Options dialog reveals many extra configuration settings. The extension can zoom into images and video, and it can alter audio volume or mute videos, configure delays, show/fade animation duration and more. Customising the Hover Zoom+ settings allows for a fine-grain per-site control (see the Sites section), including the whitelist mode.
In our tests Hover Zoom+ worked fine with almost all sites, with a few exceptions. This was because the extension relies on a list of supported domains and site building frameworks, which you can review under the Plugins section. The list covers many news sites and other popular online destinations.
Hover Zoom+ is available for Firefox, Chrome and Edge browsers. Other Chromium-based browsers such as Vivaldi and Opera also support it via their Chrome Web Store integration.
