Well, done some testing and so far I've noticed the following:

Generic bookmark icon is different/missing? (Dashed rounded edge box, recall it being a globe or document.)

Several of the "about: " pages were not working on the first time launch of TFF 8.0b1 (Upon second launch, they now work fine.)

Clicking on a bookmark in the bookmark menu while holding the Command key does not open the bookmark in a new tab, but Instead opens in the current tab. (Works fine if it's a link on the page or the bookmark is in the bookmark bar.)

I haven't noticed any major performance improvements... But then I haven't been browsing on my PBG4 in a while. I'll have to download TFF7 and see if there is any noticeable difference in performance.

Otherwise another successful release.
