Web UI Constantly crashes



this is very frustrating and keep happening on basically any FG i have deployed. Most of them are 5.2.2 or 5.2.4. No matter what browser i use, after 2-3 minutes the GUI simply crashes and i need to refresh the page (F5 refresh). With long configuration changes i always lose and need to start from the beginning. The actual http server in the FG works, i dont have to restart it, is the GUI itself the crashes and a refresh of the page always fix it.


I cannot be possibly the only one having this issue. Any help is appreciated.

Internet Explorer seems to work fine for me (V11) and MS Edge. do you tried without any add-ons?

I only see something like this happening when the fgt goes into conserve mode and/or on firmwares with "memory leaks"; mind you this is mostly on 4.1/4.2/4.3 firmwares.  On one of the 5.0.x firmwares, I have to be careful about editing long MAC Address reserves lists (like 60+ entries) via the GUI - otherwise I'll end up loosing the entire list just by adding one address change.  Browse-wise, I mostly exclusively stick with Firefox - a colleague uses Google Chrome and we noticed certain page elements don't show up in that web browse.  (Didn't ask which version of GC he was using).
