[Issue] Slow on Firefox but fast on Edge

I love your product and have been using this extension on Microsoft Edge for months. However, when I switched to Firefox, I noticed that the extension for Firefox was much slower than Edge's.

Sometimes even a simple search takes more than five seconds, which is definitely not a pleasant user experience. It is so slow that I have to turn it off frequently.

I would be grateful if you could fix this problem asap. Thank you!
