What does CRX stand for?
CRX most commonly refers to Google Chrome extensions—the packaged file used to install add-ons in the browser. It is also the gene symbol for cone-rod homeobox, a transcription factor critical to retinal development. Context will tell you which CRX is meant.
Chrome extensions and the CRX file format
Key points
CRX denotes the packaged extension file format used by Chrome and other Chromium-based browsers. The list below summarizes how it is used and what it contains.
- CRX is the file extension for packaged Chrome extensions (for example, myextension.crx).
- The CRX package includes a manifest file and related resources that allow the browser to load and run the extension.
- Typical distribution occurs through the Chrome Web Store; developers can also sideload or load unpacked extensions in developer mode, depending on browser settings and version.
In everyday use, CRX is encountered when installing or updating Chrome extensions, and the format is tied to Chrome and other Chromium-based browsers, with security considerations guiding how extensions are sourced and loaded.
Other contexts where CRX is used
Beyond software packaging, CRX also appears in biology as a gene symbol. Here is the primary non-software meaning:
- Cone-rod homeobox (CRX) gene: a transcription factor essential for the development and maintenance of cone and rod photoreceptors in the retina; mutations can be associated with inherited retinal diseases.
Outside of computing, CRX most notably appears in genetics as CRX, illustrating how the same acronym can have very different meanings in different fields.
Summary
CRX most commonly stands for Chrome Extension in tech contexts, referring to the packaged .crx file used to distribute browser add-ons. In biology, CRX refers to the cone-rod homeobox gene, a key regulator of retinal development. Always consider the domain to interpret the acronym correctly.
What is the full meaning of CRX?
Civic Renaissance Experimental
The widely accepted acronym is "Civic Renaissance Experimental." It was known by many names -
What does CR-Z stand for?
CRZ can stand for several things, most commonly Coastal Regulation Zone (a term for regulating activities along a coastline) or the Honda CR-Z car, which stands for "Compact Renaissance Zero". Other meanings include Congestion Relief Zone in New York City and the City Revitalization and Improvement Zone (CRIZ) program in Pennsylvania.
Common meanings of CRZ
- Compact Renaissance Zero: This was the name given to the Honda CR-Z hybrid sports car. It signifies a "renaissance" or new beginning for compact cars, a "zero starting point" for Honda to create a new type of sporty and efficient car.
- Coastal Regulation Zone: This is a regulation in several countries, including India, that controls activities in coastal areas to protect them and the environment. It divides coastal land into different zones with specific rules for each.
- Congestion Relief Zone: A zone in New York City that charges a fee for vehicles entering a specific area to reduce traffic.
- City Revitalization and Improvement Zone (CRIZ): A specific program in Pennsylvania designed to encourage economic development in designated areas of up to 130 acres.
Is the CRX engine made by Honda?
No, "CRX" is not a Honda engine; it is the name of a Honda car model. While CRX models are Honda cars and use Honda engines, there is also a separate brand called CRX Engines that makes engines for other equipment, such as pressure washers.

- The Honda CRX is a two-seater sports car manufactured by Honda.
- Honda built various engines for different CRX models, such as the 1.5-liter engine in early models or the 1.6-liter DOHC VTEC engine in later, high-performance versions.
- "CRX Engines" is the brand name for a line of gasoline engines produced by Crosspoint Power & Refrigeration for equipment like pressure washers. These engines are not made by Honda.
What is a CRX?
A "CRX" can refer to a file extension for Google Chrome extensions, a specific model of the Honda CRX car, or a CRX gene involved in vision. The meaning depends on the context, as a CRX file is a browser package, a Honda CRX is a compact car from the 1980s and 90s, and a CRX gene is a specific genetic marker.
In the context of computing
- CRX file: This is a package file used by Google Chrome and other Chromium-based browsers to distribute extensions, themes, and apps.
- It is essentially a zipped archive containing all the files and code needed for the extension to function.
- These files are used to install extensions from outside the official Chrome Web Store or for developers to package their creations.
In the context of cars
- Honda CRX: This was a popular two-door, three-door hatchback sports car produced by Honda from 1984 to 1991.
- The acronym is widely accepted to stand for "Civic Renaissance Experimental".
- It was known for its fuel efficiency, performance, and handling, and the Si (Sport Injected) trim was a particularly sought-after model.
In the context of biology
- CRX gene: This refers to a gene that codes for a protein called the cone-rod homeobox protein.
- This protein plays a crucial role in the development and differentiation of photoreceptor cells in the eye (the cells that detect light).
- Mutations in the CRX gene are associated with certain vision disorders, such as Leber congenital amaurosis and cone-rod dystrophy.
