Hi Community,
I have spent some time researching this issue and, according to the articles I have read, I believe this problem is associated with add-ons that may be installed on your Firefox web browsers.
In order to reslove this problem, please select "Add-Ons" from the Firefox "Tools" menu. Then, click disable next to the first add-on, return to the Auctiva website to check if the error is still being generated. Repeat this process for each additional add-on until the problem is resolved or you have disabled all of your add-ons. If the problem is resolved after you have disabled a certain add-on, feel free to re-enable all of them except for that specific one.
