MacOS – How to disable search suggestions for Safari 6

That approach is more of a straight-to-hard approach. An easier method would be to retain one browser (Safari), and import your old bookmarks into the new Safari under a specifically titled folder to separate them, and sort/delete them at your leisure.

If you would like to make it more difficult on yourself and you don't care for FireFox, Chrome, etc. I would suggest using Webkit, since that's the underlying guts of Safari, and the experience will be the most streamlined for you.

I have a similar workflow that I've used in Safari and I've used the Edit Name Feature to make it easier to move from one site to another.

If I bring up a chart of SSO in Stockcharts.com and create a Bookmark, the Bookmarks Toolbar Menu shows it as SSO - Stockcharts Workbench - Stockcharts.Com.

Then I "Show All Bookmarks", right-click (control click) edit the name SSO - Stockcharts Workbench - Stockcharts.Com to be just SSO.

This now appears as SSO on my bookmark toolbar list. To switch to this bookmark, I can choose it under the Bookmarks menu or Bookmarks Toolbar. What I usually do is use Cmd L which highlights the address bar, type SSO and Safari displays a short list of History and Bookmarks. I scroll down to SSO under Bookmarks and hit "Enter" for my SSO chart. This bypasses using the mouse and gets me right to the chart with just a few keystrokes.

As another example, I get to Apple with CMD L, AAPL, cursor down to AAPL site I want and hit Enter.

Here's a screenshot for AAPL with several bookmarked sites that include AAPL.

I like using Cmd L for two reasons. I can move from one bookmark to another without needing to use my mouse or trackpad. Plus the shortened SSO Name sits on my Bookmark Toolbar using much less space than if I added it to the Toolbar with the original bookmark title.
