FF is a buggy piece of crap that gets worse with every release. It leaks memory like a cheap hose leaks water and just loves to consume your whole cpu if given half a chance.
That being said, it’s still my primary browser because of the incredible productivity addons made for it.
1. Look at all of the extensions and addons and disable all that you don’t need, which is most of them. You’ll notice a bunch that were installed behind your back by every crapola program every installed on your computer.
2. After long usage times, exit FF and start fresh, as FF will grow infinitely large in size as well as accumulating other problems from long term usage.
3. Make sure you have the latest adobe flash reader for FF installed.
4. Flashblock and “adblock plus” help too.
No, not infinitely. At least not if you update things regularly!
I’m sitting around 2 weeks uptime, and I’ve had FF open at all times since the machine was last rebooted. There’s a definite minimum, but also a pretty definite maximum it never goes above under normal usage, before it releases some resources back.
I monitor fulltime as I’ve got a rather suspect video card fan (but the potential replacement is no prize either, so I’m staying with this one til it’s *dead*) and the app monitors temps, fan rpm, and resources. This has all stayed very steady over the past year.
All else aside, given how often it goes back down to starting levels, you should be able to keep things going for an impressively long period by just restarting FF occasionally when it asks after an update.
We’re not talking a top of the line machine...it was $300 4 years ago, running 2k Pro, 1.25 GB ram.
Oh, the one thing that can bring FF screeching to a halt? ABP filters! Be very sure if you use this and have multiple subscriptions, you keep an eye on what overlaps and what may cause slowdowns. Every so often if the update server isn’t responding quickly when it wants to update, we have a veeeerrrrrrrry unhappy machine for a minute or two.
