Greetings... I’m using Firefox Quantum - 61.0.1 (64-bit) as my default web browser. For as long as I can recall, I’ve been able to select hotlinked text or images that appear in e-mail messages that I’ve received and the content would open in my Firefox web browser without difficulty. Suddenly and recently (within the past two weeks), when I select any of these hotlinked text or images that appear in e-mail messages, nothing happens – absolutely nothing – no error messages, and Firefox doesn’t open. However, when I change my default web browser to Internet Explorer or some other web browser, the hotlinked text or images that appear in e-mail messages will open in the default web browser when selected. My hunch is that a recent Firefox version change may be the source of this difficulty. I use Windows Live Mail as my e-mail client software. I routinely receive WLM e-mail messages that contain textual and image hotlinks that I’ve been able to click on, which would open the information in my Firefox web browser. Then, sometime in the past week or two, I’ve noticed that when I’ve clicked on the WLM e-mail message textual or image hotlinks, nothing would occur – nothing. My first diagnostic step was to copy the textual or image hotlink source information and paste it into my Firefox web browser - the information would open in my Firefox web browser without difficulty. Based on these results, it appeared that Firefox was no longer recognizing the WLM e-mail message textual or image hotlink as a hotlink. My second diagnostic step was to change my default web browser from Firefox to Internet Explorer. Next, I opened a WLM e-mail message that contained a textual and an image hotlink and clicked on each of the hotlinks – both opened immediately in Internet Explorer, just as they *used* to open in Firefox. So, it’s my hunch that sometime in the past week or two, my Firefox web browser version was updated, which resulted in this difficulty that I’ve encountered. I can't recall making any changes in the Options section of my Firefox web browser in the past two weeks, which is why I attribute this difficulty to a version update of my Firefox web browser. I'd prefer to use Firefox as my default web browser, so I'd appreciate any thoughts you might have as to the source of this difficulty and any corrective action that I might be able to implement to restore this functionality for my continued use. However, if this difficulty is associated with a version update of my Firefox web browser, I'd appreciate your recommendation what next steps I should take to share this information with Mozilla so that they can investigate and implement appropriate corrective action. Thank you very much for your assistance! ...trbenjeski
