 When updating multiple citations in a batch, it may happen that citation queries are blocked by Google Scholar for multiple automated requests. If a blockage happens, the add-on opens a browser window and directs it to http:https://scholar.google.com/, where you should see a Captcha displayed by Google Scholar, which you need to enter to get unblocked and then re-try updating the citations. It may happen that Google Scholar displays a message like the following "We're sorry... but your computer or network may be sending automated queries. To protect our users, we can't process your request right now." In that case, the only solution is to wait for a while until Google unblocks you.

 ## Extra Column Info
 Currently, Zotero doesn't have any special field for the number of citations, that's why it is stored in the "Extra" field. To sort by this field you have to add it in the source listing table.
