I want to delete the Yahoo toolbar. Selected "Tool" then "add-ons".but add-on page won't load, loading icon keeps spinning for an hour. Re-booted, but same.
I looked at some of the suggested fixes and did click on Extensions then back to Add-ons, but still won't load. I also un-clicked so that add-ons aren't automatically updated, but it still won't load.

First, if the active category on the left side of the Add-ons page is Get Add-ons, click Extensions to bypass whatever is loading and go directly to the area likely to have the toolbar. (I think it's loading a page of popular add-ons, which isn't very relevant to what you want to do.) Does that work?
If that doesn't work, you could try disabling all add-ons first and see whether that makes a difference. You can do this using Firefox's Safe Mode dialog.
First, I recommend backing up your Firefox settings in case something goes wrong. See Back up and restore information in Firefox profiles. (You can copy your entire Firefox profile folder somewhere outside of the Mozilla folder.)
Next, restart Firefox in Firefox's Safe Mode (Diagnose Firefox issues using Troubleshoot Mode) using
Help > Restart with Add-ons Disabled
In the Safe Mode dialog, check just the box to "Disable all add-ons" then click Make Changes and Restart. Does this allow you to access the Add-ons page?
