I really liked Firefox but I have moved over to Chrome (

) almost exclusively now because of Firefox startup problems.
The trouble is I miss some features in Firefox and the extensions I was using and I prefer not to have all my web traffic tracked by Google!
The problem is that when I click on Firefox it loads quickly enough with my usual 6 tabs but then the tabs stop loading for about 30-40 seconds, I get an error that LastPass can't connect to its server (not actually true it is just the delay starting up giving a false error). Finally when it loads it works fine but it is really annoying that I have to wait everytime I open FF.
Leaving it running in the tray would, I suppose, solve the problem but I don't want it running all the time.
I have reported this issue with LastPass a number of times to LP support and they have helped sometimes - usually with non-binary test builds - but the issue always returns when LP updates to a new version. It isn't PC specific, it happens on all the computers attached to my network (currently 5).
This problem stops if I disable LastPass and it doesn't seem to affect other browsers at all.
Any one else experiencing this or have a solution?
