Looks like the default value for `loop.gettingStarted.url` is missing a trailing slash '/' at the end: `https://www.mozilla.org/%LOCALE%/firefox/%VERSION%/hello/start` I think (?) this could result in the FTE opening a new tab every time the conversation connects, as bedrock will append a trailing slash when the page opens like e.g. https://www-demo2.allizom.org/en-US/firefox/37.0a1/hello/start/?utm_source=firefox-browser&utm_medium=firefox-browser&utm_campaign=settings-menu When testing locally this missing trailing slash was the reason one of my machines was opening a new tab every time, while the other was not. But then I noticed the default value in Firefox is also omitting a slash.

# History This was determined here: https://bugzilla.mozilla.org/show_bug.cgi?id=1099462#c3 I'll also mention that we'll need to double-check the Tour link from the Gears menu. + :jaws as he worked on the original bug.

Going to fix and try uplift to Beta today.

/r/1625 - Bug 1114486 - Add a trailing slash to loop.gettingStarted.url so switchToTab works properly with the redirect adding the slash. r=jaws Pull down this commit: hg pull review -r 92c5974cabe078f8d12b29605e7293d360a3adc7

For more context, we need the URL path to match for switchToTab.
