Firefox 社群討論區

I would appreciate whatever help or suggestions someone may provide to an irksome problem that only happens in my preferred browser, Firefox. I've attached an image below of a page from a local grocery store. Like most stores these days, it is possible to search within that store and its web site for specific items and prices, etc. It works in at least two other browsers I've tried but not in Firefox so a setting, I'm guessing, has been changed within Firefox in the last few months (because this problem did not occur before then).

As you see in the image, I've inserted an item to find its price; and nothing happens. Before, on Firefox, and now with other browsers, I would get a display of all relevant products, prices, quantities, sales and discounts, etc.

What Firefox setting do I need to change so this information will show up again?

I have Firefox version 137.0.2 on this system running Windows 10 Version 22H2 (OS Build 19045.5737).

Sorry for my ignorance; and thanks again for whatever help anyone can offer.

I have been getting the following message several times: "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window. Close Firefox" I check my programs and I am only running the current version on Windows 10 Pro. Why do I get this message?

Can't use YT picture in picture mode on Firefox when logged into my YT account. When I enable picture in picture on a video and scroll down to the comments, picture in picture mode turns off as soon as I scroll past the bottom of the video.

Happens only when I'm logged into my YT account on Firefox. Logout, it works. Logged in on Edge, it works. Logged into my second YT account on Firefox, it works. Only doesn't work for this one account.

Attached images if that helps. Last image shows exactly when picture in picture mode turns off when I'm scrolling
