Why do I always have to enter "captcha" on a site I visit regularly?

We use Vendor Central, an Amazon site for vendors who sell to Amazon, as my husband and I do. No other search engine requires that we have to fill out a captcha every single time we log on to vendor central. Why does MF?

Hi darsani, it is up to a website whether to use a CAPTCHA or not. Have you asked Vendor Central under what circumstances they require it?

Some sites may require extra authentication the first time, and then set a cookie in Firefox so that on your next visit they can see that they already authenticated you. If you are not keeping cookies between sessions -- either because of settings changes, using private browsing, add-ons that modify cookie handling, or external software that cleans up after Firefox -- that could explain why on some sites you need to re-authenticate after closing and re-opening Firefox.

thank you for your message but i don't know what i'd have to do to fix this, even after reading your answer. neither google chrome nor IE, require captcha but amazon prefers we use this site and it is really annoying to have to do this. please advise how i can change settings so this won't be required.

You may have to create a third-party cookie "Allow for Session" exception for involved domains in some cases to avoid cross domain issues where Firefox is blocking some cookies.

You can temporarily enable all third-party cookies to see if that helps and which cookies are created and send.

Thank you, How do I do that?
