Just the one MN tab open on my browser

I get the above message often when I browse MN, especially on longer threads such as the current one in AIBU re ambulance services. This message usually follows my laptop overheating and usually precedes me having to completely refresh the page as everything will start to feel sluggish. Anyone else experiencing anything similar?

Hi @zagaraz can we check if this happens when you have several tabs open? This might be the cause if so.

Please also try force quitting Safari:
Click the Apple apple logo in the upper-left corner.
Select Force Quit from the dropdown menu.
Choose the Safari application

If it's still happening after force quit, please clear the browser's cache. Instructions can be found here.

Let us know how you get on.

I get this too
