Links in Apple Mail not opening in Firefox 15

Links in messages in Apple Mail have recently stopped opening Firefox tabs and windows. The Mail window fades, as if a new window or application were being accessed, but nothing happens. I have reset my default browser (according to Mozilla instructions) in both Firefox and Safari. I have also checked all add-ons to see if they might be causing the problem and nothing changes when all are disabled. If I set Safari as default browser, it works fine.

Any thoughts? (FYI, while not totally incompetent or technically illiterate, I am also not all that schooled in the details of computer know-how and haven't gotten much beyond the options available on the toolbar and the limited information found through a quick Google search. It seems others have had this issue in the past, but I haven't found a fix that works for me yet.)

Thanks.

Hi!

Is Mail the only external app that has that problem?

I remember having a similar issue and that was caused by an add-on who was messing up with the Firefox behavior.

If this is the case, you should see the same behavior when opening links from other apps.

To resolved, you have 2 options. Either use Firefox Reset (Refresh Firefox - reset add-ons and settings ) or try to use Safe Mode (Use Troubleshoot Mode in Firefox ).

Firefox Reset will reset the majority of your Firefox settings (including the add-ons) while keeping the most important information safe (Bookmarks, etc). In the other hand Safe Mode will allow you to test Firefox with a clean profile and then it will allow you to disable all the Add-ons. If that solves the issue, you should activate the add-ons one by one until you find the one it's causing the problem.

I hope this helps you.

Hi Ibai, and thanks for your help. I had already checked all add-ons and plug-ins, but tried opening Firefox in safe mode in any case and the problem persisted. It also appears that it is not just an issue with Mail; if I click on a hyperlink in a word or pdf document, nothing happens. So the issue appears to be with Firefox. I went through the various steps you suggested and those you directed me to on Mozilla's site, including the troubleshooting process and even the Firefox reset, but the problem is still occurring.

Does anyone have thoughts on what can be done about this? It really is quite frustrating.

Thanks.

Hi speakec!

Have you checked if Firefox is defined as the primary browser? Now that you mention that is not only Mail, that's my strongest theory.

Make Firefox your default browser 

I hope this solves the issue.
