I recently had techs install an SSD in my laptop. Now in Thunderbird, I can't open links to web pages. I've tried making changes in the Thunderbird Config Editor, but this didn't help. When I click a link in an email, the color briefly changes to red, then nothing happens. When I right click the link and click "Open in Browser," the little blue "processing" circle shows for an instant, then nothing happens. Thank you for any help you can give.
