INSTALL

How to install

Windows installerRun the setup; it installs for your user only, no administrator rights. The installer is not signed yet: Windows SmartScreen asks once - choose "More info", then "Run anyway".
Windows portableUnpack the zip anywhere and run psippr-browser.exe inside the psippr-browser folder.
Debian, Ubuntusudo apt install ./psippr-browser_…_amd64.deb - or from our repository update.psippr.cz: sudo apt install psippr-browser. Needs Java 21 (installed with the package).
Other LinuxUnpack the tar.gz anywhere and run psippr-browser/psippr-browser; Java 21 must be installed for PSippr Services.

Updates come as new packages from this page, the store and the PSippr repository; Mozilla's own update is off, it would undo the PSippr changes.
