Why does Firefox 12 quit opening emails after it has successfully opened many beforehand?

When I click on an emails label, Firefox opens it so I may read it. However, after successfully opening several such emails, the system will then stop doing so. Instead all it does is change the unread email's label from being 'bold' (indicating an unread email) to just normal (indicating the email has been read - even though it has not).

Please give more information. What email client are you using?

Does the problem still exist if you start firefox in Diagnose Firefox issues using Troubleshoot Mode?

Hi, I'm not sure what you mean by 'email client'. I am running Firefox 12.

The system hangs at various random points. For instance, it will hang if I click to open an email; if I try to delete one; etc. It does this after I've been using Firefox for 15-30 minutes.

Now lately (in about the last week), it has not frozen on me. But I can't rule out that it won't again because it does not hang consistently every day.

As for trying it is Safe Mode, I could try that, but it may take at least 2 weeks of usage before I would feel comfortable giving you the results. Even at that, they would be questionable - simply because of the randomness of the problem.

Wish I could be of more help...Morgan.

Hi Morgan,

I just meant are you using hotmail / gmail / yahoo etc?

But from your response I can see that the problem is more general. Not just with your email client. It seems more like an intermittent hang / freezing problem.
