About Firefox Klar
Firefox Klar is an Android communication application published by Mozilla under the package name org.mozilla.klar. It belongs to the communication category, and this listing presents the verified technical details you need before putting it on a handset. Version and release information The build supplied here is 157.0.1, released on 2026-10-06. Holding the current build is the simplest way to keep the app in step with the developer's ongoing work, since Mozilla regularly issues newer builds of its products. Space the install needs The package occupies 227.0 MB, so it counts as a fairly substantial download rather than a lightweight utility. Make sure your device has that much free space available alongside your existing apps and media, or the installation may fail partway through and leave you to clear room and start again. Compatibility and device support The build requires Android 2026 or newer, which sets a clear floor for handset compatibility. Owners of that generation or newer devices are the intended audience, while anyone running an older system release should confirm their software version first, since the app is not offered for setups below the stated threshold. What this listing does not state No content rating has been provided for this package, and the file type is likewise unlisted, so the entry relies on the numeric size and version figures alone. The developer is identified simply as Mozilla, and no additional tags or feature categories accompany the record.
