Odd back button behavior in Firefox

Chrome and Edge don't exhibit this behavior. I suspect it has something to
do with the title changing due to the test timestamp combined with whatever
behavior changes in FF.  I have several tests that run every 2 minutes --
UPS monitoring.  I was updating one of them and spent a good while on that
page testing my changes.

Not the end of the world but minor annoyance.

Thanks for confirming my experience and the commiserating.

I'm having odd behavior with Mozilla Firefox's back button while viewing

first
noticed it.

Navigating to the test page is fine.  If I view the test then
immediately use
the back button, Firefox goes back to the page/subpage.  If I stay on the
page for subsequent refreshes, I have to hit the back button once per
refresh
that happens.  If I stay on the page long enough, the back button history
fills and I can no longer use the back button to get to the page/subpage.

Interesting issue :-) I have just tried this with Firefox 95.0.2. The FF
'sessionhistory' setting is set at 50 by default. So leaving a Xymon test
page
refreshing for a while I found that I had to hit the back button 46 times
to
get to the original page. Needless to say if I left it a bit longer, then
I too
would not have been able to get back to the original page using the back
button.

In our case we only have a main page listing the hosts/tests, no sub-pages
and
the like. So to get back from a test page is easy enough anyway.
