so i checked now and then if an update work correctly, which didn't until now.
yesterday everything worked and so i'm really happy with the "new" 25.3.1.
maybe it's interesting for others how to do. anyway, it is not a great thing, don't expect any problems. on three others winxp systems there were absolutely no problems
- Palemoon 24.7.2. --> update to 25.3.
- updated Palemoon 25.3. --> restart
- then update your add-ons and restart
- check again for updates, Palemoon 25.3.1 will occur --> update & restart
- again check for add-on updates ('https everywhere' finds updates again) & restart
- now you can download your language pack ( http://www.palemoon.org/langpacks.shtml) and restart browser for the last time
all of my add-ons working correctly, except "minimize to tray" which is known not to be compatible and is not longer in development (edit: simple workaround here: viewtopic.php?f=16&t=5890&p=51383#p51383) and of course ad-block, which i dont use.
i hope this will help to take the fear away for updating from the old 24.7.2.
edit: i'm aware it's the 1.april today
