Back tab limit

Questions and suggestions about how far back you can back tab the linked sites. I noticed that when there are too many links in a tab, the oldest drops off and you can no longer back tab to it. (1) Is there an option to set how many links are allowed before drop off occurs? (2) When that happens, how does it affect the JAVASCRIPT history.go() function? (2a) For HTML the first time the <body onload='function()'> the function can find the programs position in the link chain by using history.length. However, later (like returning from a link) is there a way to find that position? Saving it has hazards. Maybe you can suggest a history.current element. (3) I would like a way on browser screen to make the current link the first link (drop all the prior ones). It would reduce memory requirements. (I know, this should go in the suggestion box, but it is closed).

For #1:

The Back button history is limited to 50 entries by default. Obviously not all of these are visible on the list, it takes many steps to get back to them.

The preference for that in about:config is browser.sessionhistory.max_entries (applicable to current session).

At shutdown, the list is trimmed to 10 entries by default.

If you need more back button history in a restored tab, the preference for that is browser.sessionstore.max_serialize_back (for restored tabs).

For #2/2a, I'm not sure I understand the question.

For #3, I'm not aware of a way to erase all the back history in one go, but if you click in the address bar and press Alt+Enter, the current URL will be re-launched in a new tab that has no tab history (and then you can close the old one).
