Not sure if I’ve fixed anything yet, but so far, I haven’t had problems running Firefox for the past 15 minutes.
Starting this morning, I noticed that Firefox kept hanging. It repeatedly stopped responding, and I had to force it to close. I got home tonight, and the same thing happened. I ran a virus scan, nothing. I ran a tune-up program and found 229 registry errors. I fixed that, but still the same. It still stopped responding. I upgraded Firefox to the latest version. Same thing. I restarted Windows. Still no change. Finally, I went into control panel and fiddled with the settings in power options, changing the hard disk power down to 60 minutes. That seems to have solved the problem…I hope.
