When Using Firefox With Google Search I'm Required To Do A Captcha Everytime Since Recent Update

Hello, Since receiving a recent update to Firefox (I am a long time user), when using Google as the search engine, I am required to complete a Captcha every time, because Google says it has detected unusual activity from my location. Firefox is/has been installed on my computer for many years without any problems. It is used as supplied with the following extensions:- Ad Blocker Ultimate; Duck Duck Go Search & Tracker Protection; Enhancer For YouTube; Firefox Relay; Malwarebytes Browser Guard; Privacy Badger. If I change the search engine to say "Duck Duck Go" I don't get any Captcha requirement. I use Bit Defender Antivirus protection. Malwarebytes Free is used as a periodic check and is not activated to work full time. This problem didn't exist until a recent Firefox update. The Captcha requirement happens every time I use Firefox with Google search and if I boot up the computer and immediately use Firefox and no other program I get the Captcha requirement. How can there be "unusual activity"? If I use Google Chrome Browser, I don't get the Captcha requirement, it's just Firefox. With all the extensions from Firefox removed I still get the Captcha requirement. Any assistance would be welcome.
