Try to redo the default browser setting and temporarily set another browser as the default browser. You may have to do this in the Safari Preferences.

Thank you for your reply. Getting Firefox to work as my default browser is not the problem. The problem is: when I click on a link (eg in an email), Firefox comes to the front without problem (it's my default browser); but nothing more happens - no new tab - if I already have one or more tabs open. I have to shut all tabs first before the new link will open in a new tab. This has not happened in any previous version of Firefox - it's new to version 32.

You seem to be running Firefox in Private Browsing mode.

• browser.privatebrowsing.autostart: True

Make sure that you do not run Firefox in permanent Private Browsing mode (Never remember history).

• https://support.mozilla.org/kb/Private+Browsing

• Firefox > Preferences > Privacy > Firefox will: "Use custom settings for history"
• Deselect: [ ] "Always use Private Browsing mode"

Other users noted that if Firefox was hidden in the dock, they had to click the link twice, once to unhide Firefox and again to actually load the link. Not sure if you have the same issue or that is a different issue.

It's a different issue, but thank you for your reply.

Thank you for your reply. If this is the only way to solve my problem, I think I shall switch to Safari as I wish to retain "never remember history". I'm also puzzled as to why this setting (which I've had for years) has not caused a problem in earlier versions of Firefox but (apparently) does now.

Hi outthere1000, could you try the nonprivate just as a test? It might not actually make any difference, which would be useful to know in troubleshooting this.

Hello, thanks again for your reply, As it turns out, I was already running "Use custom settings for history". So I guess "Never remember history" isn't the problem.

You could try the Private Tab to get Private Browsing mode support per tab.

• Private Tab: https://addons.mozilla.org/firefox/addon/private-tab/

about:config page:

• extensions.privateTab.allowOpenExternalLinksInPrivateTabs = true

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

Thanks for this. I'm not any sort of expert so I'm not clear what the above suggestion will do to save any time or solve my original problem. As things are now, I can simply copy the URL and paste it into a new tab and keep all my current settings - but what I want is for the old system of simply clicking on a link to get it to open in a new tab to work again.

Further to jscher2000's suggestion yesterday: I think I misunderstood the suggestion, which I didn't find very clear. I've now discovered that if I send a Firefox open window (with one or more open tabs) to hide in the dock first, then clicking on a link twice (once to bring the mail program to the front and again to open the link), this will cause the hidden tab/s to come out of hiding AND a new tab for the link will open. Cumbersome, and I still maintain there is a bug in version 32, but this workaround is at least quicker than copying and pasting the link. Thanks to cor-el and jscher2000 for your responses.
