Anyone know?

I want to either decrease the file size allotment for history, or be able to delete 'forum'-related history entries, or 'eBay' entries, etc.

I do not want to 'Delete Browsing History'.

What browser would that be then?? Sounds unlikely whichever one it is.

Nearly all browsers have some option for specifying the size of the cache used. In Firefox it's found in the "advanced >> network settings" panel. There's also usually a setting for how many days your history entries will be saved. Firefox has this in the "privacy" settings tab.

You should also be able to delete specific pages from within your history list display, the one that usually opens up in the sidebar, though this may or may not delete the corresponding cached files.

There's a "cache viewer" extension for Firefox that lets you browse, and optionally delete, individual files in the cache.

I do FF browser; not sure which version...

I found the 'MINIMUM' days to keep history, but 'MAXIMUM' is what I'd prefer.

Cache viewer extension sounds like what I seek; how do I launch that one?

Which browser are you using? If firefox, enter "about:config" in the address bar and then "history" in the search bar. You can change the maximum history value there.

Try Help->About. It gives you the version and release in most GUI programs.
