Hi all,
I am using Firefox Portable 5 and for the past couple of days external links are opening in a new window, rather than a new tab.
As far as I know I haven't changed anything.
The settings in Tools, Options, Tabs specify external link to open in new tab, as does the Tab Mix Plus extension.
I have tried Firefox in Safe Mode with all extensions disabled and also a clean profile that I have using the 2nd Profile app.
With the extensions disabled on my main profile the problem still occurs.
I have also reset all Tab Mix Plus settings to defaults.
