Try going to the Tools menu item, and choose Options.

In the popup, select the Advanced screen (cog icon) and under that, the Update sub-tab. On that tab, uncheck the various boxes for checking for updates, and see if that helps?

I hadn't noticed anything other than accept or 'ask me later' but the next time it comes up, I'll look, thanks.

Ooh no, didn't have to wait that long, it's just come up again!

Actually I've realised you don't mean on that nag screen but in FF and yes, I can do that, but then I'm not going to get update notices at all. Ideally I'd just want this to go away for a fortnight or a month, so that as soon as the AV plug-in is updated, I can then install 5.0.

Which AV program are you using?
Are you sure that your AV program doesn't have a Firefox 5 update available, already?

I read that Norton had an update for Firefox 5 available on 6-21, the day Firefox 5 was released - but it has to be installed after Firefox update is installed.

I have searched on their site (avast) and found no reference whatsoever. I might try that on the linux box though, as I can sandbox it.

Thanks.

Sorry, I haven't seen anything about Avast having an update for Firefox 5 available yet.

Overall, you're not going to be any less safe without that Avast plugin, than you are with that old Firefox 3.5.4 version - which is no longer supported and is 15 updates behind the last security update that Mozilla released in March.

I'm on 4.0.1 - as specified in my system details. I see it says I'm on 3.5.4 as well but I don't know where it got that from, I certainly didn't write that.

A beta version of Avast is available: http://forum.avast.com/index.php?topic=80428.0

Or as in the second post in that forum thread "You can also uninstall webrep from your current avast to have the compatibility with FF5."

Thanks - I couldn't even find the forum!

although your second point doesn't really resolve the issue as laid out in this thread, I'm happy to give the beta a go.

You are welcome.

Tip: to find something like the Avira forum, go to google.com, enter "avira forum" (including the quotation marks).

On the main avira.com page, click Support (at the top), choose the type of support, scroll to the bottom of the page and there is a link to the forum.

Or alternatively, companies like Avast could include their forums in their search results so that customers searching on their site for "Firefox plug-in" or "Firefox 5.0" would actually get some meaningful results!
