GitHub Flex Firefox

GitHub Flex

Expand GitHub's interface - wide layout, expandable tables/images, GIF picker, sidebar toggle, edit history diff viewer

Features & Capabilities

GitHub Flex enhances GitHub's interface with powerful productivity features that make your daily workflow smoother and more efficient.

Features:

• Wide Layout: Expands GitHub pages to use the full width of your browser. No more wasted screen space - see more code, diffs, and content at a glance.

• Table Expand: Expand, resize columns, and hide/show columns on large tables. View tables in fullscreen mode. All customizations (column widths, hidden columns, expand state) persist across page loads.

• Image Lightbox: Click any image on GitHub to view it in a fullscreen overlay. Easily inspect screenshots, diagrams, and visual content without opening a new tab.

• GIF Picker: Insert GIFs directly into comments, issues, and pull requests. Search from a huge library powered by Giphy - add reactions and fun to your conversations.

• Sidebar Toggle: Hide or show the GitHub sidebar with a single click or the Alt+M keyboard shortcut. Reclaim horizontal space when you need to focus on content.

• Edit History: Enhanced diff viewer for comment and description edits. Click "Split View" in any edit history dialog to compare changes with word-level highlighting in split, unified, or rendered markdown preview modes.

All features can be individually enabled or disabled from the popup settings. Your preferences sync across devices via browser sync.

Lightweight, open-source, and built with Manifest V3. No data collection, no tracking - just a better GitHub experience.

Is GitHub Flex 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.

GitHub Flex requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details
  • Critical Request access to the following domains: github.com
  • High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
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.

GitHub Flex is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.

Risk likelihood analysis details
  • High This extension has low user count. Unpopular extensions may not be stable or safe.
  • Medium **** ********* *** ******* ** *** **** * ******* *** ******* *** *** ** ****** ** *****
