Hi,

Please also try right-clicking the Firefox icon and Run as administrator.

Hi,

Thank you for that.

It did work, but with problems.

When Firefox restarted after telling it to update, it was running in standard user mode and said that there was another instance running, so I had to close it down and run it again as administrator.

When it finally restarted, it had lost all of the tabs I was using, including all of the App Tabs. History showed no previous session, no recently closed tabs, and no recently closed windows. Still, I've got most of them back now. Is there any way to stop this happening in future? Is there a way to save the entire current state?

Firefox run as administrator now shows, under Help|About Firefox

Firefox

11.0

Firefox is up to date

When run in standard user mode, it shows

Firefox

11.0

Apply Update

Does this mean that I must always run Firefox as administrator if I want to get updates automatically? Or is there some way to persuade it to look for updates even when run in standard user mode.

Thanks again,

Mycroft

I have done as you suggest above, but when I close and re-open Firefox in a standard account, Help|About Firefox still shows

Firefox

Unfortunately this did not happen. I have also lost all tabs in the past when Firefox has crashed (not every time). Fortunately History|Show all History has kept all its data, so I can reconstruct most of what was lost.

I will keep my fingers crossed about this, but given the "Apply Update" shown in a standard account, compared with the "Firefox is up to date" shown when run as administrator I am not sure whether it will get that far. I shall wait and see what happens when the next update is rolled out.

Thank you very much for all the help you have offered. It is much appreciated.

Best regards,
