Hi, there was a bug in one of the 5.2 version of Vivaldi but it is fixed in Vivaldi 5.3.
There are some issues in this version therefor the auto update is disabled at moment. You can download it and install as a standalone install to test or wait a few days.
Check the block/forum for news about the new 5.3 status.
