From the documentation talk page:
The Problem: The auto-start download in the ExtensionDistributor makes the Opera web-browser reload the page after 5 seconds, instead of auto-starting the download.
Version: Opera v10.10 stable-built:1893 Windows7 --FarwayK 14:09, 24 January 2010 (UTC) BTW I've never experienced this problem anywhere before.
This problem still exists and this ExtensionDistributor is still the only place where this happens.
It makes downloading extensions manually almost impossible with Opera. The refresh sends you to http://www.mediawiki.org/wiki/Special:ExtensionDistributor thereby losing the chosen extension and version data.
The only way to stop this is hitting the stop button immediately when the page starts refreshing, before the current page turns blank.
Current Version: Opera v11.00 stable-build:1156 --FarwayK 19:05, 30 December 2010 (UTC)
Version: unspecified
Severity: normal
