From my experience using Safecache on a dialup account does cause dramatic slowdowns in page loading on all sites.
If you have Stealther installed and have FF set to clear Cache etc. at close isn't this enough??
I am seeing that and I doubt safecache is long for this life on my system, but I'm trying to be patient and give it a fair test.
I do have stealthier, but very rarely use it, so much so I almost forget it is available and as for the deletion of the cache on shutdown, that to would contribute to a major slowdown. In much the same way as safecache having multiple caches relating to a particular origin/page, having no cache at the start of each day I feel would be even worse.

I don't see how pocket firefox would make surfing faster (I don't care much about how long it takes to load), over the standard firefox. If it has the same, functionality, extensions, caches in the same way, etc. then I can see how it would be faster and if so why have standard firefox if pocket firefox is better
