User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.1) Gecko/20090630 Fedora/3.5-1.fc11 Firefox/3.5 Build Identifier: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.1) Gecko/20090630 Fedora/3.5-1.fc11 Firefox/3.5 In previous versions of FF, I could click on a URL in other apps (e.g. my mail reader) and get a new window, but if I clicked from *within* a FF window I'd get a new tab. I liked this behaviour, but it seems to be impossible to get with FF 3.5. The option only allows new windows always, or new tabs always. Reproducible: Always Steps to Reproduce: 1.Click on a URL in mail reader 2. 3. Actual Results: With Preferences->Tabs->"Open new wondows in a new tab" is set, I get a new tab, but the main FF window is often on a different virtual desktop from the mail reader, forcing me to switch desktops to see it. Alternatively, with the option turned off, every URL click gets a new window, which is clumsy. Expected Results: Open the URL in a new window on the same desktop, but if I click on a URL inside a FF window, open it as a new tab. This is what previous versions of FF did and it seemed to me correct.
An alternative to adding yet more options to the Preferences dialog would be to have a command-line option "-new-window" (perhaps also "-new-tab" for completeness). Then the action to be taken from other apps -- which generally allow the user to specify a Shell command to execute on clicking on a URL -- could be set up individually for each app. Note that the existing "-no-remote" option is useless for this, at least under Linux (complains that FF is already running).
