Site Blocker blocked every site on the internet
Literally. I downloaded an add-on to Firefox called SiteBlocker and when I went to block a site it blocked every single accessible site on the internet (including the homepage and all the search engines). So when I open it up, it just gives me a blank page and tells me the site was blocked. I tried uninstalling and reinstalling the browser but that did nothing. I had to use Microsoft Edge to post this. I also don't know how to delete the add-on because I can't even get to it.

You can start Firefox in its Safe Mode, where all extensions are deactivated, and remove it there. At least, I hope you can remove it there; if it installed externally, you might need to use the Windows Control Panel.
If Firefox is not running: Hold down the Shift key when starting Firefox.
If Firefox is running: You can restart Firefox in Safe Mode using either:
- "3-bar" menu button > "?" button > Restart with Add-ons Disabled
- Help menu > Restart with Add-ons Disabled
and OK the restart.
Both scenarios: A small dialog should appear. Click "Start in Safe Mode" (not Refresh).
Then you should be able to get to the Add-ons page and remove this thing.
To return to normal, exit out of Firefox and start it without holding down the Shift key.
Success?

Also, can you ID this thing specifically? While in Safe Mode, before removing it, you can copy/paste its name and ID from the Extensions table on the support information page (use any of these to access it):
- "3-bar" menu button > "?" button > Troubleshooting Information
- (menu bar) Help > Troubleshooting Information
- type or paste about:support in the address bar and press Enter
