One way is to use whatever version is installed via the distro's package management system as primary, and use Mozilla.org's static builds as additional, which is a relatively simple process. Simply download the Firefox .bz2 build of choice, and extract into a dir such as ff4, ff2 or ff5 in /usr/local, /opt or even /home/<username>.

Startup can be facilitated by adding the specific versions as new menu items and using -no-remote -P profilename as startup options, but starting from a term or shell provides the option to see error messages that may occur running or starting up. -no-remote as a startup option allows you to have multiple versions open concurrently. I typically have at least 6 Gecko versions open 24/7, save for restarts.

Ubuntu Linux 10.04.  Serious testing/benchmarking is beyond my time constraints.  As per what David suggested, I seem to recall disabling the developer toolbars in the past and seeing less if any performance hit. It's more of a feeling than reality.  Next time this happens I'll monitor more closely if I disable the toolbars. I also have Seamonkey, Epiphany and of course Konqueror installed of course with no additional toolbars. They 'feel' quicker but it may be because I don't run them long enough for any latency build up.  Yes it does seem to be related to time.  No it's not related to a particular website.  When one is impacted all are impacted.

Anyhow, I will monitor better.  Was really wondering if anyone else had encountered the same.
