Firefox issues. DO NOT UPDATE!

No it's not only this site.
Not too certain what's causing it.

What happens is when you access a page it will load really slowly and the scroll bar will switch to the left hand side of the page. At work it was constantly causing Webmarshall to ask for authentication. Spent the best part of the morning chasing it and eventually I uninstalled 3.5.5 and went back to 3.5.0 and all is now good. Happened on both my work PC and this Laptop I'm using now, both XP SP3.

Also, pages that were open in tabs before the update will open OK. Any new pages from the same site were screwed.

Strangest browser behavior I've ever seen..

This article describes it pretty well.

And this one..

and there are a few others on the Mozilla support forum.

I'm on 3.5.5
and have been for since i rebuilt the hard drive...all ok to date

G'day Mr Bitchi,

Thanks for the heads-up. I'm using 3.5.5 on 3 machines with XP SP3 and on 2 running Ubuntu 9.10 and can't say I've had any problems with wandering scroll bars or other display flakiness.

However, I have noticed one of my usual sites (www.theregister.co.uk) now seems to take forever to load (if ever) as described in one of the Mozilla Support articles you posted. I'd put it down to the fact that I mainly read El Reg on an EEE PC that's not exactly endowed with grunt.

Guess I'll stay tuned and see what eventuates.

Cheers,
Chris

And where do they get the 'Millions of users' from. We've been running Win7 here at work on thousands of computers for a few months now (and yes I can back up the total number) and haven't noticed it yet. And yes, the updates are up to date...

I am also running windows 7

Hi Geoff,
I use XP on all my machines, plus AVG (coz it's free!) and I've recently been having a sort of connectivity problem with FF; ie, nothing happens untll one re-tries, then it works. All machines exhibit the same problem. It may still be a problem with my ISP, tho, as I'm also having occasional email connectivity problems and I've got to do a bit more sleuth work. Maybe AVG is causing both problems.
I certainly don't get the above issues with LH sliders, etc. Everything works on FF, it just doesn't do it first time. No probs with IE or Chrome. I find Chrome fast, but it seems to take up lots of resources, but that's only on one slow machine with limited memory.
cheers
Gerry

Niether of my PC's that had issues are running AVG. Have Symantec on the work PC and Avira Antivir on the laptop.

You've described my problems exactly. Removed Avg and problem went away.

Geoff,
thanks, you've pointed me in the right direction. Might give a different virus scanner a go.
Pity, I've always liked AVG (mainly coz it's free!)
