Features & Capabilities

Default Zoom is a minimalist Firefox extension designed to set your preferred default zoom level across web pages, enhancing readability especially on QHD or HiDPI monitors. Unlike bulkier zoom add-ons, it’s incredibly lightweight, with just 30 lines of JavaScript, ensuring minimal performance impact.

The extension respects per-site zoom preferences with one exception: it overrides the default 100% zoom on page reload due to API limitations, ensuring your chosen zoom is always applied without storing extensive per-site data. It requires no special permissions other than storing a single setting, making it privacy-friendly. Being fully open source, users can view or modify the source on GitHub. If simplicity and minimalism are your priorities, Default Zoom offers a clean, effective solution for zoom management in Firefox.

User Reviews

The Default Zoom add-on is a small, easy-to-use tool that reliably fixes a default zoom level with minimal fuss and no data permissions. It is praised for its simplicity and effectiveness. However, several reviews note that Firefox already provides zoom settings, making the extension seem redundant or obsolete in some situations. Memory behavior for per-site zoom is inconsistent across users, leading to mixed opinions on its ongoing value.
Pros
  • Reliable default zoom control that works as intended across Firefox versions.
  • Lightweight and minimal with no permissions required.
  • Simple, single-purpose extension that does exactly what it claims.
Cons
  • Redundant with Firefox's built-in default zoom and per-site zoom features for many users.
  • Inconsistent per-site zoom memory across sites or restarts depending on version.
  • Some users feel the addon is unnecessary given Firefox settings.

Is Default Zoom Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Default Zoom does not require any sensitive permissions.

Risk impact analysis details
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
