PROGRAMHAPPY  Developer, I have a HUGE feature request that I think will be quite helpful to many users. There is (was) an add-on called "Twicetab" (see "Twicetab 1.3.1.1" here at macupdate), but it doesn't work on Safari 4. One of the optional features of TwiceTab that I desperately miss is the ability to make a URL (or domain name) in my clipboard open in a new tab. For instance, if I copy the text "http://www.google.com" or "google.com" and then double-click on an empty space in the Bookmarks Bar, it will open the Google home page in that new tab. However, if there is no URL or domain name at the top of my clipboard, the double-click action in the Bookmarks Bar will perform the user's default preference (home page, blank window, etc.) for a new tab. Whadaya say, guys? Hook us up!

Thanks in advance!

PROGRAMHAPPY  It does NOT work with Safari 4.03 and SIMBL 0.9.2b.  
(Version 0.6.5)

TWISTED  Finally a simple tab manager for Safari without bloated features :)  
(Version 0.6.5)

DROOPYSIGNAL  It would be nice to have the option to open tab sets or none with a key modifier at start up.  
(Version 0.6.5)

MACSOLU  Just installed this update, along with CosmoPod and TabExposé -- now I cannot use my mouseball/wheel to scroll up or down web pages while viewing them in Safari. I have yet to troubleshoot, but at least one of these three plug-ins is the culprit.

FUHAYER  could not find SIMBL folder to move this patch. i use snow 10A432 :S

NEIL_M  @Chrisza

Read the requirements above;

Mac OS X 10.4 or later, SIMBL, Safari 4

Have you installed SIMBL?

In the time it took you to write your comment, you could have searched for it and installed it.

SIMBL - http://www.macupdate.com/info.php/id/18351/simbl  
(Version 0.6.3)

CHRISZA  Err, it says to install I must drag bundle to a SIMBL/Plugins directory.

No such directory on my new powerbook 10.5.6  
(Version 0.6.3)

SHANE C SMITH  Search for Glims, it will do this and so much more.  
(Version 0.6.3)

CALL ME YO DADDY  Sorry to crash the party but I was using Saft for better tab functionality before this came out. However a simple terminal command is all you need to make Safari's default tab functionality mirror Firefox and Opera's. This commands simply opens links in a new tab instead of an annoying window. Expert from MacUser:

You are required to launch Terminal (which can be found safely nestled within /Applications/Utilities) and enter this command:
defaults write com.apple.Safari TargetedClicksCreateTabs -bool true

Once you hit return and relaunch Safari, you’ll find that it will never steer from the noble path of the single window web browser now, no matter how trying the circumstances. The gates to ultimate web surfing joy will part and you and Safari will live happily ever after. 

COLIN  The option to force links that open a new window to open in a new tab doesn't work with Safari 3.1.  
(Version 0.6)

ALEXIUSCA  Very promising, however it's frustrating that the plugin asks you if you want to restore, even when there are no windows to restore. Please make this a bit smarter!!  
(Version 0.6)

DRUMMIST53  crashes my MDD G4 Safari 3 every time..had to remove it..  
(Version 0.6)

LANOUVELLECHAIR  It's nice but it will be great if this plugin force windows to open in tabs too.  
(Version 0.5)

FFASS  Works fine for me. Running Safari 3.0.4 on Mac Pro, OS 10.5.1. Session history is recalled spiffily.  
(Version 0.5)

BRAZIL  does not seem to work at all-I see no changes in Safari Prefs,,  
(Version 0.5)

BILLY THE BIKER  Seems to be boken with the Leopard update.  
(Version 0.4.1)

A J BENAMU  It still crashes Safari... very very bad!  
(Version 0.4.1)

ANON BUD  Let’s hope it works better now. It does not warn me when closing a window with more than one tab open.  
(Version 0.4)

A J BENAMU  Safari crashes after installing. Bad bad!!!!  
(Version 0.4)

GANNET  Don't suppose it would be possible to make it so that tabs may be moved around (re-ordered)?  
(Version 0.3.1)

CUNEYT  In the latest version (0.3) there is a problem with the cooperation of SafariTabs with one of the functions of the Saft plugin. With Saft installed when you quit a tab in Safari you can restore/reopen it back with command+Z (its called Restore Closing Tab).. In the previous version of SafariTabs there was no problem. But in version 0.3 when you choose Restore Closing Tab or use shortcut command+Z it opens the same Tab/same webpage 2 times in stead of just 1 time.

I hope you can fix this issue, in the previous version there wasnt a problem like this one..  
(Version 0.3)

SPRINGHEELMAC  Ok, I guess I'm an idiot, but can you put in a 'read me' file for installing? I can't seem to locate the library that the plugin goes into.  
(Version 0.3)

MONTRAK  There seems to be a bug with the recent version. Couldn't close Tabs and Windows. I had to use a forced quit. I went back to version 0.24. No problems.

NORAA  Seems a new bug has popped up in this latest release - the Google search in the menu bar no longer seems to work. When I type something in it, and then hit enter, nothing happens. Minute I uninstall SafariTabs all is well again.

Otherwise, great little plugin.  
(Version 0.2.3)

MYSTICALOS  one thing that's always annoyed me is the contextual menu when you click links and you want to choose "open in new tab" and assidently get "download link" instead. I do this a lot. sure I could just command click but I'm just too used to doing it this way since ie 7 works same way. perhaps some tweaking could be done there by chance?  
(Version 0.2.3)

CUNEYT  Thank you Developer for fixing the problem which I mentioned below.. Thanks for your quick update.  
(Version 0.2.3)

CUNEYT  When downloading something, and you have just one tab open.. It quits immediately when doing command+Q or choosing Quit Safari from the menu.. It doesnt even give a warning that you have downloads running, it quits immediately.. That made me uninstall this bundle, because I had to start download everything all over again.. I think it should give you a warning when quitting while there are downloads running.. That is also a default thing in Safari..  
(Version 0.2.2)

HENRIKTEKNIK  I previously used TabStop, which does the same, but TabStop didn't offer what SafariTabs does, namely the option to choose a custom webpage to open, when you make a new tab.  
(Version 0.2.2)

CALLE  This functionality should be built in. I suppose SafariTabs does the job well in the meantime, though I don't like to have too many plugs installed and have instead put a never-used button right below to close button, to minimize the number of times that I accidently closes the window when all I wanted was to go back.
