A new update has appeared for Firefox – 18.104.22.168 – that claims to fix a number of memory leaks. I’m trying it out now. So far, it looks ok – seems to get to just over 70Mb, then stop growing.
The proof will only really come after a day or so of heavy use, though – 1.5 was getting up to over 370Mb, which was enough to make it pretty much unusable for me. I do hope it’s better – I do miss all the nice extensions when I’m using IE. Unfortunately, the new Google Toolbar that supports our PigPog Toolbar Button isn’t available for Firefox yet, but I doubt Google will take too long to sort that out.
