Lost all my buttons with 102.0. Will an update for the new version be possible?

Edit: thanks for the reply.

Ok found the problem. Your addon is indeed still working however the code for creating separate buttons with .uc extension no longer does. You posted it previously:

let protocolHandler = Services.io.getProtocolHandler("file").
QueryInterface(Components.interfaces.nsIFileProtocolHandler);
let userChromeDirectory = Services.dirsvc.get("UChrm", Ci.nsIFile);
for (let file of userChromeDirectory.directoryEntries) {
if (! file.leafName.endsWith(".uc.js"))
continue;
let url = protocolHandler.getURLSpecFromFile(file);
Services.scriptloader.loadSubScriptWithOptions(url, {
target: document.defaultView,
charset: "UTF-8",
ignoreCache: true
});
}

If the code is placed in userchrome then it's good.

This review is for a previous version of the add-on (1.0).  This user has a previous review of this add-on.

I'm not sure what you mean by "buttons" or what "buttons" have to do with userChromeJS. I just tested userChromeJS with TB102 today and it seems to work just fine. If there is code in your userChrome.js file that's creating buttons of some sort, and that code is no longer working in TB102, then I don't think that's because userChromeJS isn't working, I think it's because the code isn't working, and that's not anything userChromeJS can fix.
In any case this isn't the right place to seek support for the add-on. Please see the support email address on the add-on home page for further assistance.
