Hover PDF

Minimalist PDF reader packed with power for academic reading. Read academic papers with easy navigation, split mode, embedded annotations, and in-place citation preview.

Features & Capabilities

=========================================================== Hover is a minimalist PDF reader built for people who spend way too much time reading academic papers in the browser.

Features

  • Inline Citation Preview Hover over any citation and instantly see the full reference. Say goodbye to scrolling to the bottom of the page. Click once to browse the paper's abstract without ever leaving the current page.
  • The Navigation Ball A compact, beautifully designed controller that replaces the traditional toolbar clutter:
-- Left-click to open the standard toolbar -- Double-click to jump to the top of the document -- Drag vertically to scroll freely without touching your mouse wheel -- Drag horizontally to reveal the table of contents and jump to any section
  • Split Mode Open two views of the same paper side by side for cross-referencing methods with results, or appendix with the text.
  • Paper Trail system (Experimental): Tracks your trail from one paper to other through citation abstract preview jumps. Up to 8 trails can be saved, you can star trails to prevent them from being erased.
  • Action Tool system: Search tool button at the top-right corner now becomes an action button. Drawing tool: Smooth line drawing support that can be embedded into exported PDFs. Crop Tool: You can crop any area on the paper and get a high resolution rendering image to add to your clipboard. You can customize the default action tool in the settings.
  • Night Mode A true night mode that inverts and dims the entire page for late-night reading sessions.
  • Search With Range Limit any search to a specific page range or document section, so you're never wading through irrelevant results.
  • Persistent Annotations Highlights, underlines, and comments are saved directly into the PDF file. The annotations are fully compatible with other PDF readers and easy to share.
  • Direct BibTeX Access Copy any citation format, including BibTeX, with a single click from the Cite button.
  • Vim Keybindings Supports hjkl for scrolling, J/K for page navigation, and gg/G to jump to the top or bottom. More coverage coming soon.
  • Fully Customizable You can choose a wallpaper (upload or from url) and pick a color scheme for your navigation ball to make it feel like home.

Is Hover PDF 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.

Hover PDF requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

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.

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