Firefox 3.5.5 'bogging' down.
I've just upgraded Firefox to 3.5.5 and I'm finding it very slow - as if the internet connection is restricted (yet IE8.0.6001.18828 works much faster) - both with Vista Home Premium - Intel DuoCPU T6500 @ 2.10 GHz & 4GB RAM on a laptop (new in August 2009).
Even things like cut and paste (within Firefox) seem to have significant latency (10 to 15 seconds) between instructing and execution.
(IE8 averages 2-3 seconds for this)
Any ideas?
Rebooting seems to ease the situation initially, but the treacle soon arrives.
Is there any way to wind-back Firefox to an earlier version (to see whether it really is the update that has caused the problem)?
