Status: NEW

(SeaMonkey :: Tabbed Browser, defect)

User-Agent:       Mozilla/5.0 (X11; Linux i686 on x86_64; rv:2.0.1) Gecko/20110531 Firefox/4.0.1 SeaMonkey/2.1pre
Build Identifier: Mozilla/5.0 (X11; Linux i686 on x86_64; rv:2.0.1) Gecko/20110531 Firefox/4.0.1 SeaMonkey/2.1pre

In Seamonkey 2.0.x, middle-clicking the "new tab" button opens a new tab
and loads the URI from the clipboard.  However, in the 2.1 release candidate,
it opens two tabs: a blank one, and the one you wanted.

Reproducible: Always

Steps to Reproduce:
1. Copy a URI into the clipboard
2. Middle-click on the "new tab" button

Actual Results:  
A blank tab is opened before the tab containing your URI.

Expected Results:  
No blank tab.

Do you have an extension installed like the Tab Clicking Options extension?
Please test with SeaMonkey in safe-mode:

[Ian Collier]

The only extension I've installed is Scriptish.  It still opens two tabs in safe mode.

Comment 3

Is this Linux specific?

In Windows, I can /only/ get a new tab?

I have the following settings, any more I may be needing?

browser.tabs.opentabfor.middleclick;true
middlemouse.contentLoadURL;true (modified)
middlemouse.openNewWindow;true
middlemouse.paste;true (modified)
middlemouse.scrollbarPosition;false

Is this still reproducible with modern SeaMonkey versions?

Probably fallout from: Bug 603095 - Accept middle-click for new tab button
> Recommendation:
> When middle-clicking the "New Tab" tab, open a new tab. :)

Yes, SeaMonkey 2.8 still opens two tabs.

Comment 7

[NoOp]

Confirmed:
Build identifier: Mozilla/5.0 (X11; Linux i686; rv:11.0) Gecko/20120312 Firefox/11.0 SeaMonkey/2.8

Middle-clicking the New Tab button results in two 'Untitled' tabs. The second 'Untitled' tab has the clipboard contents (in this case the Build Identifier info pasted above) in the URL bar.

In Tab settings I only have the followng choices ticked:

Tab Display
- Switch to new tabs opened from links
When opening a bookmark group
- Add tabs
Open tabs instead of windows for
- Middle-click...
- Ctrl+Enter in the Location bar

I have the same settings on a Win7 install (SeaMonkey 2.8) and middle-clicking New Tab button results in a magnifier icon with '+'. The cursor can be moved away and the magnifier icon remains over the New Tab button.

Um.
1. Make sure that the clipboard contents is a valid URL.
2. On Windows, I think you might have the OS Accessibility->Magnifier turned on or perhaps an extension installed.

Re: Comment #8

> 1. Make sure that the clipboard contents is a valid URL.

It pastes whatever is in the clipboard to the URL/I bar. As you wish:

1. I copied this URL to the clipboard:
<https://bugs.gentoo.org/show_bug.cgi?id=409455>
2. Repeated the test (linux) in Comment #7. The results are the same; the data in the clipboard are pasted into the URI bar. In this case the URL opens the URL in the second tab.

This is the same behavior as mentioned in Comment #1.

Windows:
> On Windows, I think you might have the OS Accessibility->Magnifier turned on or perhaps an extension installed.

The settings for Advanced|Mouse Wheel are the defaults:
- Vertical & Horizontal scrolling are set to 'Use system default' nothing else is checked.
- No clue what 'OS Accessibility->Magnifier' is.
- Same behavior when restarting with Add-on's turned off (Safe Mode). Also the same behavior with a clean test profile (no add-ons/extensions other than what is bundled in SeaMonkey: Chatzilla, DOM Inspector, and JavaScript Debugger).

> - No clue what 'OS Accessibility->Magnifier' is.
Start->Control Panel -> Ease of Access Centre -> Make things on the screen larger
[X] Turn on Magnifier  <=== turn this off!

Or just:
Start->Control Panel -> Ease of Access Centre -> Start Magnifier

Comment 11

[NoOp]

@Philip + Accessibility->Magnifier; I seldom use Windows any more, but I can assure you in Win7 that the 'Start Magnifier' is *not* enabled. Recommend that you find a regular Win7 user to test in that OS further. 

I can recreate the symptoms of Comment #1 and Comment 9 in linux (both 32bit and 64bit Mozilla installs) at will on multiple machines. However I've just tested on a new install & found that I *cannot* reproduce. So the issue must be in the user profile settings somewhere. If you can give me about:config settings to look for I'll compare against the 'clean' machine to try and pin it down.

[Philip Chee]

NoOp: what is your about:config setting for middlemouse.contentLoadURL on those profiles with the problem vs those without the problem? Also compare the other middlemouse.* preferences.

[Phoenix]

Is this still present in latest SeaMonkey version?

Comment 14

[Ian Collier]

I have Seamonkey 2.46 (20170120202356) and yes it still opens two tabs.

Comment 15

[NoOp]

I no longer use Seamonkey so I am no longer able to help troubleshoot or verify.
