This is usually because of either:
- A collision with another extension like LastPass. You can right click in the text field and click "Authorize with Throttle" as a workaround. We're looking into longer-term solutions.
- Cookies are disabled, or only allowed for certain sites. Whitelist Throttle in your browser to enable it to save cookies, so that the extension can generate your Throttle addresses.
If Throttle doesn't automatically place a button in a field that you would like to generate an address in (it happens every now and then), just right click that text box, and click "Authorize with Throttle".
So far, this has been because of AdBlock. Try whitelisting Throttle in AdBlock, and everything should work fine.
It appears to be a bug affecting some users on El Capitan. https://discussions.apple.com/thread/7254177?start=0&tstart=0
There are two reported solutions:
- Reboot into safe mode to install extensions (not ideal)
- Use the keyboard to select 'Trust' rather than the mouse.
I think option 2 would be the way to go. Here's how to do that:
Go to System Preferences > Keyboard > Shortcuts. In the bottom section there is the text "Full Keyboard Access: In windows and dialogs, press Tab to move keyboard focus between:". Under that, select "All controls". Now the user can use Tab when the prompt to install the extension
Make sure you're using Chrome when you click the button to install the Chrome extension, it should open the Chrome Web Store panel with the Throttle extension to install.
Usually this happens when cookies are disabled, or only allowed for certain sites. If you whitelist Throttle in your browser to enable it to save cookies, the extension can generate your Throttle addresses.
