Default Firefox and its "where was I?" stack depth when traversing a page tree.

Hello all,

I'm using Firefox, and sometimes dive rather deep into a page tree. The
point is that, when I use the "back" button, the first few of those actions
get me to the exact location on the previous page where I clicked the link.
After that it just lands me at the top of the page (leaving it to me to find
the exit point back).

Question: Is there a possibility to make this "where was I?" stack larger,
and if so how/where do I do that ?

Remark: If need be I have no problem with going into about:config and change
settings there.

Google keywords/search phrases (or even links) are welcome too (currently
can't think of any).

Regards,
Rudy Wieser

"...bfcache, which is a term invented by Mozilla), involved when the user
navigates Back. Unlike the regular (HTTP) cache, it captures the
complete state of the page (including the state of JS, DOM)."

https://stackoverflow.com/questions/...he-back-button

Not every page is preserved that way. Some pages are marked as
needing to be reloaded. That would cause the origin to change
(when the page is reloaded).

Paul,

Thanks for the "bfcache" keyword & link. Though it seems to concentrate on
throwing scripting at it, and giving very little pertinent info about the
former.

Googeling for "bfcache" and "scroll restoration" (something that also popped
up) did not come up with much either.

I did find a reference to "browser.sessionhistory.max_total_viewers", but
alas, no mentioning on what the current value is when its set at "-1"
(default) - or even if its actually related to my described problem.

Oh well ...

Regards,
Rudy Wieser

I believe page states are stored in the memory cache (disk cache only stores
the original resource contents, BTW). e.g. scroll position, form field
contents, JavaScript code contexts, etc. So, try increasing the memory
cache. In `about:config`:

browser.cache.memory.max_entry_size

If you type `memory` to filter the settings, you'll find other memory
settings which may affect the problem (those whose name begins with
`browser.` and `memory.`).

But site scripts may choose to dynamically reset/refresh the page if they
want to.

JJ,

I've just added a zero to both entries, to see if it makes any difference.
If it does I will remove the zero from the disk cache, and see what happens
than.

By the way, the explanation to the "browser.cache.disk.max_entry_size"
setting on developer.mozilla.org says: "The maximum size of an entry in the
disk cache". Which I read as a the size of a *single* entry (but whith no
indication of the number of entries in sight tho).

In that case I read it as if it will just ignore pages with too much
transient data on them (as if they would exeeded the maximum size).

But site scripts may choose to dynamically reset/refresh the page if
they want to.


That won't be a problem in my case: I've got scripting disabled. :-)

Rudy Wieser

Hmmm. Didn't seem to change anything. Just three "back"s and I got thrown
to the top of the page again (and noticed it re-retrieved the involved page)
