MRC  Hmmmm... not sure why my reply to O5220803 got posted as a new post in this thread, but it did. But Thx for your input O5220803, see above for my reply.

MRC  yup, I purged cache, cookies and history when the issue first emerged (I should have mentioned that in my original post).

GORDON142s idea seems to have worked somewhat... I still get very slow page loads, but at least the entire page loads. Before, I would often get a page that was "done" but still had not loaded the main body of text. I had to refresh to get the page to load completely.

I think I will use Appcleaner and Easyfind to remove all of FFs components and then reinstall the browser from scratch.

MRC  Thx GORDON142. I will give that a try after backing up bookmarks etc. Your help is greatly appreciated. And... here... we... go!

MRC  Since upgrading to Snow Leopard has anyone noticed that FF 3.5.x takes foreverrrrrrrrrrrr to load pages and that sometimes those loads are incomplete? I removed the 3 add ons I had installed to see if they were the culprit, but it has not solved the problem.

I have been a longtime user of FF and while not always the fastest browser for Mac, I always felt it was a very solid product. But for the first time I find myself looking for other options, like Chrome, which seems to run very well and QUICKLY. So far FF Support has been useless telling me that "FF is being evaluated with Snow Leopard." (Thx guys, that is very helpful).

Anyone with bright ideas are welcome to chime in.

Running:

MacBook Pro early Core 2 Duo

OSX 10.6.2

Firefox 3.5.5

MRC  Odd, I have an Intel Mac running 10.5.8, but for some reason I get a message that I can't install this version of Chax?! Anyone have any ideas?

MRC  Yeah, with the most recent update I noticed my cooling fans working very hard too... I used Activity Monitor, but could not find the culprit. It seems that certain Flash heavy web sites cause FF to go nuts and push my MacBook Pro's fans into overdrive!?

MRC  About to add this app and take it for a test drive. Just wondering how it works... is it an application that runs in the background like Hierarchy or OldFolder?
