[Bug 1017427] [NEW] Since Firefox 13 tabs are reloaded automatically after starting Firefox when focussing them

[Micha Rabe]

Public bug reported:

Up to version 12 the user could determine by himself when content was
being reloaded.

Since version 13 firefox reloads every tab after starting the programme
when putting the focus on this tab, even if the content is stored in the
cache memory. So the user gets the new content from the internet, which
is very often the error page 404.

I have received some tips that didn't help yet, e. g. to change the value of
browser.cache.check_doc_frequency
to 2 (= always use the cached version).
That does, what it is supposed to do (only load a new version of the page if the user gives the command to do so), but it doesn't prevent reloading cached tabs when visiting them.

How can I either
- stop this unrequested behaviour
- or go back to Firefox 12 (under Xubuntu 11.10)?

Thank you for your help!
Micha
