The Pale Moon browser has a button that pops up a list of sites you've visited recently. You can set it to keep sites for months, so it's very useful for finding sites you visited but can no longer remember. Does Slimjet have a feature like this?
EDIT: OK, I found the answer. Just place the History button on the toolbar.
And if your trying to keep the toolbar slim and trim you can mash Ctrl+H to open the history tab.
And if your recent history from a still open tab is what your looking for, click and hold down the click over the back arrow (like your going to drag it) to reveal the back history, and the same for the forward history on the forward arrow. This current tab history will be available from this method if one or both arrows change color.
For those of you who wear aluminum foil hats, the voices lie, don't believe them!
Mostly my replies are about Windows OS. If not I try to remember to specify Linux.
