So you have some old sites that you frequently use, and some of them work better with Flash Player 9, or in my instance use an uploader that has not been rewritten for Flash Player 10.
You only need it now and then - what do you do? Can you have both? Yes you can and here is how I did it.
Everyone is different, so to commence with I have a MacPro running 10.6.1 - you could be on 10.5 on a MacBook - shouldnt really make a difference, but I could be wrong.
You could download the flash player uninstaller, but when i tried it just sat there wheeling away and basically doing bugger all - so I canned it. Perhaps it's not 10.6 ready...
1) I went to
Macintosh HD > Library > Internet Plug-Ins
2) Then, I selected the following files:
Player Enabler.plugin
Flash Player.plugin
flashplayer.xpt
3) I then created a new folder called 'FP10' and put the 3 files above there. As long as these files are not in the main folder, your browsers wont find them and thus no flash player.
4) Here is where Adobe make things hard. You have to download the a 200mb download just to get to a 4mb file - thanks Adobe!
Download this
http://fpdownload.macromedia.com/get/flashplayer/installers/archive/fp9_archive.zip
Then unzip it and go to
fp9_archive > 9r246 > flashplayer9r246_ub_mac.dmg
That puts two new files into
Macintosh HD > Library > Internet Plug-Ins
Flash Player.plugin
flashplayer.xpt
And these are the Flash Player 9 pluggins.
Thats it - your now using FP9.
If you want to flip back up to FP10 - put those two files above into a new folder and call it FP9. Place the other 3 files back into the root directory from your F910 folder and your ready to rock again.
Hope that helps!
