Hi Fred, I'm using Google mail. I haven't yet tried another browser. I will try that. Meanwhile, when I did use the basic config, it worked ok. Of course I don't want to be stuck there.

Are you talking about safe Mode?

Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes). If the problem goes away, that tells us one thing. If it does not, that tells us something else.

No I'm talking about the basic mode display that I'm advised to use when I get that error message.

What basic mode?

This is the msg I get. Something I failed to mention before (I hadn't made the connection) that's independent from Google: Firefox has started to show some pages as code either just before it loads the actual page or it sticks there and doesn't load the page. Basically symbols and question marks. This occurs randomly as far as I can tell. Not every time.

Contact G-mail support. The message is from them.

Clear the cache and remove cookies only from websites that cause problems.

"Clear the Cache":

• Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"

"Remove Cookies" from sites causing problems:

• Firefox/Tools > Options > Privacy > "Use custom settings for history" > Cookies: "Show Cookies"

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
