Joyron, I'm pleased that it brightened up for you today. Like you, my weekend doesn't look too promising, but I think you will find that Sunday is better than Saturday, and Monday looks really sunny at present.
Yogi, it's strange that you are having problems with Firefox, I haven't had any problems today. I have recently cleared the browser cache, so I wonder if you cleared that it might help. Tools - Options - Advanced tab - click on Clear Now, then on OK to do this.
I'm fairly certain that Firefox and IE use different caches, so clearing the cache on one browser doesn't clear on the other one.
squiggle, it's a nightmare if you have to delete the firewall and anti-virus to get online, and rather risky. I've never needed to do that. Sometimes if I have installed a new program, I need to switch them off during installation, but before I go back on the web, I switch them back on. Switching off the antivirus s/w is less serious as it is used for checking stuff on your computer, so unless you are looking at emails and other things you can get away with it for a short time. But if you have to switch off the firewall, that is much more serious and if I have to do that I actually take the broadband cable out of my computer so that whilst the firewall is off, it is impossible for baddies to get access to my computer. I get frequent firewall messages that it has prevented access from certain hacking sites. In my case, it's always the same criminals - they are based in China which makes it near impossible for the authorities outside China to do anything about it. It's not known who is behind these attacks, though the Chinese authorities may have an idea, but - I'm not going to start speculating as to who it may be.
What I do know is that if I switched off my broadband, my computer would be infected within a few minutes, possibly seconds.
I have to sign off now as I'm off to see another new client - very small and a one-off.
