Google claims that Firefox AdBlock Obstructs Gmail Chat

firefox logo big Google Inc. is recommending users of Gmail Chat to disable the Firefox browser plug-in AdBlock while using the new instant messaging feature set in within the search engine’s Web mail service.

In a response to a support question, Google said that AdBlock, which is used to block advertising on Web pages, “often interferes with Gmail’s chat features, causing Firefox to crash.”

The Mountain View, Calif., company said its engineers are trying to solve the problem, but advised, in the meantime, to disable AdBlock, clear the Mozilla Corp. browser’s cache and then log back into Gmail.

Google said, “If disabling AdBlock resolves the problem, but you’d still like to use it in conjunction with Gmail, you may want to contact AdBlock’s support team for help.”

Google released Gmail Chat on Monday. The IM software is embedded into Google’s existing email service and is being unveiled gradually among Gmail users.
