My Firefox browser on my Windows 10 Surface Book is being extremely slow at loading web pages compared to my other browsers like Chrome. I have tried running exclusions on Firefox for both the Windows Defender antivirus & firewall. Moreover, I've tried reinstalling Firefox, disabling add-ons, configuring the performance settings, and restarting it in Safe Mode. Now that I think about it, this issue has been plaguing me for months, but Firefox will go back to running perfectly for weeks at a time, and then goes right back to being horrendously slow at loading web pages again. Heck, even a simple Google search seems to take ages to load! I really don't want to switch to Chrome or any other browser so I really hope the community can help me out since I'm not sure what else I can do. Thank you for any help on this!

hi, please see if the following change in configuration can fix the performance problems: go to the firefox menu ≡ > options > privacy & security panel, under the permissions section enable the setting to prevent accessibility services from accessing your browser and restart once.
