Certain tabs keep partially reloading
When I leave tabs open for certain sites, the tab will repeatedly say "Connecting...", with the gray and then green spinning ring icon. However, the actual page shown in the tab doesn't flash white or otherwise act like the tab is reloading. If I click the "Stop Loading" button, it'll stop but then do it again within five seconds.
If I ignore it long enough, it stops. It takes about the same amount of time to stop whether I'm on the tab group containing the problem tabs or not. I'm not sure if the tabs keep doing whatever it is when I'm on a different tab group.
When I disable my computer's Internet connection, the tabs still try to do this, but just flash "Connecting" for an instant and then go back to the tab's proper name. This worries me, because it makes me think they're touching my data allowance when they do this.
I've also been experiencing occasional Firefox crashes, especially when I leave the computer unattended. Not sure if that's related.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
- Do NOT click the Reset button on the Safe Mode start window.

Do a malware check with several malware scanning programs on the Windows computer.
Please scan with all programs because each program detects different malware.
All these programs have free versions.
Make sure that you update each program to get the latest version of their databases before doing a scan.

Found the problem. Seems it was HP Product Detection of all things.
Wait, never mind. Blast. Twice now I've thought I had it, only for the problem to to come back a few hours later.
