Release notes for 3.2

Changes

About the Next Version

If no new issues are discovered, this version will be the last one to support Firefox 59.

My intention for the next released version is to implement support for Manifest V3. This migration from Manifest V2 to V3 will require raising the minimum supported browser version to Firefox 109.

To put it simply, if you are using Firefox 109 or higher, you will be able to receive the upcoming version from Mozilla Add-ons, which will include various improvements resulting from the discontinuation of support for older Firefox versions.
