Some sites scroll or flash the title when there is a new message, then there will be notifications without stop. How can I deal with that?
Sorry for the late reply.
In most of the cases you can set a regular expression for that site to show just one meaningful title (e.g. to show the title when it contains "message"). In the other cases (or if you don't want to bother yourself with regular expressions) the internal algorithm to detect cycles helps to reduces the flickering and to close permanently the notifications. Unfortunately the algorithm sometimes needs a lot of time to detect cycles.
Rather that make more complex the algorithm (which could make slower the browser) in the next version I'm going to make the effects of scrolling/flashing titles much less annoying. The size of the notifications box will never change, word wrap will be used and sequential title changes of the same page will never open a new notification on the top but will update the previous one also when the cycle has not been detected yet.
The restyling of the notification box is also the first mandatory step to get to future features like "stackable" notifications.
I'm going to release the ver. 1.2.0 in AMO soon (likely by the end of the week) and it will include your localization.
Thanks a lot to you and to others that translated it, you are great!
