New to Thunderbird (TB). TB v 102.1.1 (64bit) Mac Mini late 2012 macOS 10.15.7 Catalina. Situation: My coach sent me a link to download a PDF. She sent the email with both an image link and a text link. I use "Choosy" as my browser, a nifty Mac App that allows me to choose any of my four browsers. The Problem: I have normally been using Kiwi for Gmail v3.5.0. IMPORTANT:''' Both links work.''' The image link AND '''the text link are clickable'''. I also checked using MailPlane, another Mac App, and again,''' Both links, the image link and the text link were clickable.''' However, '''only''' in Thunderbird does the "'''text link not work'''". The image link does work, i.e. it will open in my browser. What I've done: > Cleared the cache > Open in Troubleshoot mode > Referred to this help link (nothing helped): https://support.mozilla.org/en-US/kb/hyperlinks-in-messages-not-working > Tried Message Body "Simple HTML" ==> Only the 'image link' becomes an HTML clickable link. The text link remains as text. > Just for funzies: Copied the text link and pasted into Chrome, it opened the PDF. > Another for funzies: I copied the PDF link from my browser, pasted it into another account using TB, send the email with the "text link" to another account. batta-bing-batta-boom, the link showed up. My Conclusion: I'm a bit mystified. There has to be some setting problem in TB. Because as I mentioned earlier, both the image link and text link open in my browser when using Kiwi for Gmail and MailPlane App. Only in TB the text link will not open. Open to any suggestions. Please note: no biggie as the image link is clickable.
