I found this error was created by an errant URL in a call to xhrGet. By correcting the URL the error was resolved. In Chrome, the error was better identified in the response showing the errant URL. In my case, I'd embedded an undefined value in the URL request by mistake like this: http://localhost:9080undefinedjson/IssueSummaries
Perhaps because the port number was FUBAR, it causes this error to be reported? Anyway, this error was a red herring reported back from the xhrGet call to a bad URL. I'm using version 10.0.10 of Firefox. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/605513 Title: Get uncaught exception when populating a form in FireFox 3.6 Status in The Mozilla Firefox Browser: Confirmed Status in “firefox” package in Ubuntu: Triaged Bug description: Binary package hint: firefox When populating an input field on a form in Firefox (Linux or Windows) where I select or just pass the mouse over one of the historical suggestions that drops down while inputting, I receive the following error: Error: uncaught exception: [Exception...
