Thanks for the info and having already reported it to Mozilla.

I can confirm it?s working correctly now in FF 96.

I've been seeing the same thing here! Running Xymon server 4.3.30 (Terabithia RPMs). My guess is it was a Firefox update at some point that is causing the behavior...no idea what or why....

I did notice that if I hit the back button enough times, it eventually

goes

to the actual previous page...most of the time...

But glad someone else is seeing this....thought I was going crazy!

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 Xymon tests. This started somewhat recently but I don't recall when I 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.
