This release fixes compatibility with Firefox 147. Please make sure to update to it before Firefox 147 is released on 2026-01-13.

Unfortunately, there remains one known issue with Firefox 147. The address bar will have incorrect width and will not take the full window width. Any help in fixing this is appreciated. See #780 for details.

This release also changes the update checking mechanism. When the extension detects it's outdated compared to the connector and versions are compatible, it will periodically check if the new extension version is already available, and display the outdated extension warning only in that case. However, keep in mind that this will only take effect after this version has already been installed.

• Patches should now load properly in Firefox 148.

• Toolbar should no longer shrink when resizing windows (#759).
• Generating fallback icons should now work properly on Windows.

Important

According to the Firefox Add-ons Policies, communication with the native messaging host is considered data collection and transmission. To comply with that, the extension manifest now declares now declares the transmission of the browsing activity to the native program using the Firefox built-in consent for data collection and transmission functionality.

You may see a popup from Firefox when updating the extension that it may now collect or transmit the browsing activity.

No changes regarding the actual transmission have been made. No personal data leave the computer or are sent to third parties. Browsing data (the current website and manifest URLs) is only sent to the native program when installing a web app and stored locally.

• Updated translations.
• Updated dependencies.

News

There are now GPG signatures available for DEB and RPM packages. This should allow users to verify the origin of packages. This should also fix a warning displayed by some Linux software stores, such as KDE Discover.

Packages are signed automatically on GitHub Actions by the GPG key F17A EF1C 8C47 5B51 B5F3 03C6 912A D9BE 47FE B404, available on Ubuntu Keyserver and Packagecloud. This is a PWAsForFirefox-specific subkey of my main GPG key 7440 07D7 10DD C8E2 0673 F545 2D15 DC76 BD6B 710C, available on Ubuntu Keyserver and GitHub.

Signing for DEB packages is done using debsigs and may be verified using debsig-verify. Signing for RPM packages is done using rpm --addsign and may be verified using rpm --checksig.

Repository metadata are still be signed by packagecloud.io.

As a reminder, MSI and RPM packages are signed with a code signing certificate provided by the SignPath Foundation, and all built artifacts are attested using GitHub Artifact Attestations.

• Signatures for DEB and RPM packages have been added (#645).

For Package Maintainers
