Can't tick, toggle or modify Safari extensions in Preferences. I tried deleting the cache in Library > Safari following one poster's suggestions. Also tried monitoring the console following another's suggestion but no idea what I was doing or looking for.

Installing Safari extensions.

2. Download Safari Extensions from App Store.

dominic23, thanks for the reply. I went through all the steps you laid out: I uninstalled than tried to reinstall the Extensions, downloading from App Store. That didn't help and I still can't "Enable"/tick/toggle the box in Safari Preferences.
Then I restarted in Safe Mode. No issues came up, but it didn't fix itself either. Still can't "Enable"/tick/toggle the check boxes in Safari Preferences.
My OS software has been up-to-date this entire time. In fact, I feel like I'm having a lot of issues BECAUSE of the update to Catalina.
Any other ideas?
I appreciate it!
I would wait a day or so.
Then try again.
First time I tried, I had exactly the same problem.
But next time I tried, it worked.
This is the third or fourth time I am posting fresh screenshots.
Starting up in Safe Mode involves a restart, there is no pointing in restarting again.
One of those problems, I guess.
Try Emptying Safari caches.
Enable Develop menu, click Develop in Safari's menu bar and click Empty Caches twice.
Use the developer tools in the Develop menu in Safari on Mac ...
See if the last post in this discussion helps.
