As you can see, the forum is just a few pixels too wide to be able to show the ad next to it, thus bumping the menu down as well. It's no big deal, just thought I'd let you guys know. I have the same in FF, it really is my screen (it's a 17"), but I am thinking there will be more people with this screen size.
I had WoW open, then I use IE - it also saves my Addon dev tabs. Opera is for java and c++ tab saving. Firefox my general browsing :P (Yes I know I could just use save session for each of those in FF). Firefox seems to use a shitload of memory, and when I am in WoW I can't miss too much. I am a poor woman with an AMD64 3400, MSI K8N Neo Plat, 1GB Ram, ... You get my drift ;)
And Thottbot, I don't know. When I first played WoW, this was recommended to me by a clan mate (DOD Clan), and I never looked for something else. I am very open to suggestions, extremely open actually. (Please suggest something else :P)
slightly maybe OT, but quick tweak to bring Firefox's memory usage down to managable levels:
First, type about:config in the address bar. Then,
Fetch only what you click
Fx .6 and up: Firefox has this wacky little feature that downloads pages from links it thinks you may click on pages you view, like the top result on a page of Google results. This means you use up bandwidth and CPU cycles and store history for web pages you may not have ever viewed. Creepy, eh? To stop that madness, set the network.prefetch-next key to false.
This one actually helps my memory usage as well as cpu.
Limit RAM usage
All versions: Goodness knows I've done a good amount of belly-aching about Firefox's voracious appetite for RAM. (It's consistently the most memory-intensive process on both my PC and Mac.) Happily a simple config tweak got Mem Use right back down to a more comfortable number. Along with the previous prefetch mod, set your browser.cache.memory.capacity to a value that fits your total RAM.
* Key: browser.cache.memory.capacity
* Modified Value: Depends on your system's total memory. According to Computerworld:
For RAM sizes between 512BM and 1GB, start with 15000. For RAM sizes between 128MB and 512M, try 5000.
