Issues with Firefox hogging resources...
I have several issues with Firefox intermittently consuming 99-100% of my CPU memory. Now, let me preface this by saying that I am NOT an advanced user, and can only tell you what I see on things like the Task Manager and such. Furthermore, I know that you guys know about some of this stuff - at least, I am pretty sure you do - but I am nowhere near comfortable enough to mess with any command line... stuff... in Firefox. I just am not knowledgeable enough about the program, and I don't want to 'break' it (lol). Anyway, down to business. Here are the issues I am having:
1. Upon startup, Firfox takes between 30 seconds and a minute and a half to load 5 tabs. When I first downloaded and installed it, these same tabs took less than 10 seconds to load. I have tried clearing my cache and history but nothing seems to help. If it matters, I have been using Firefox for going on 5 years now.
2. Once the program has loaded, any keyboard shortcuts I use in it (ctrl+a, ctrl+c or v, alt=tab, etc) cause the CPU memory usage of Firefox to spike to 99 or 100 percent. In affect, it freezes my computer for anywhere between 2 and 30 seconds, roughly. It does this usually, but not always, and I frequent all the same sites, so the page I am on does not seem to matter.
3. I have noticed that some of the addons I use with Firefox, mainly Multi Links, lag as well when the above issue is occurring. Not sure if the two are connected in any way (also not sure why that feature is not built into Firefox to begin with) and would have checked this but I will not risk not being able to get back here again. See below.
4. This is unrelated, but I felt it merited some small mention. This is effectively my SIXTH attempt at posting my query. The first time, I created an account and it forwarded me to some page basically saying 'Yup, you're logged in alright.' Then it KEPT doing that every time I tried to flesh out and ask my question, until I navigated COMPLETELY away from the page four times and attempted this one last time. Very frustrating. I even tried going to Live Chat for help, but somehow got off the chat window page and then suddenly chat was closed... right. Anyway, point being, it was difficult to get this posted and it has me even more annoyed. >.<
I have always loved Firefox because it was faster and more reliable than IE. But here recently... it just seems to be going downhill. For instance, I have seen others ask questions about what's going on with the plugin container and that stupid flash plugin - I happen to have that issue rather severely, to the point that I must leave Flash off entirely until I have to turn it back on (which is wearing down my last nerve, I might add, since I use sites that require that particular plugin daily), and while I did see a couple rather nice solutions about editing/tweaking internal Firefox settings, I must profess that I am nowhere near competent or comfortable enough to even think about attempting them. Furthermore, I do not believe I should be required to make such changes in order to get the program to function properly and risk ruining it completely so that I have to uninstall and reinstall just so I have Firefox. This is all rather exasperating, and judging from the replies I saw on those topics, I do not expect much help here (a couple of people were rather rude on one of those topics, I am afraid I am a minority here, not knowing my way around program language and all =( ). My main goal is to make you aware, if you are not already, that issues exist and if you have tried anything on your end to rectify them, it has not worked for some. I am at my wit's end here, I do not know what else to do to try to solve these issues other than clear cache and history, restart Firefox, so on and so forth. *sigh* I'm seriously thinking about going back to IE, and you have no idea how much that really ticks me off; I think, out of all of this, even all my wasted time, that's what upsets me the most.

Issues of this sort are, unfortunately, more common and the we'd like them to be. However, they tend not to be cause by Firefox itself, but rather by software that is running either inside or alongside it, such as add-ons or firewalls. Since these issues have a broad span of possible causes, you need to diagnose your problems before fixing them. Follow these instructions to the line, as they'll probably help you diagnose and fix the problems you're having.
- run Firefox in safe-mode to disable all extensions, themes and plugins. If this fixes your problem, be it with RAM or CPU usage, then you know it's a problem with add-ons (plugins, themes or extensions). Proceed to number 2. If safe-mode doesn't fix your problem, then read bellow, after this list;
- update all extensions (go into Tools > Add-ons > Extensions > Find Updates), themes and plugins (see this page in your Firefox. If this doesn't solve the issues, proceed to the following number;
- disable all extensions, themes and plugins in your Firefox (not running safe-mode). This is temporary and for diagnostic purposes only. Being certain that, as in safe-mode, the problems you're having have gone away, enable one plugin at a time. You should be certain that you actually want that plugin to be enabled. It's best to keep the overall number of enabled plugins as low as possible. When you encounter problems, you know you've found a problematic plugin, so disable it for good. Keep enabling all plugins (except problematic ones) until you've gone through them all. If you need support for a problematic plugin, you need to contact its author for support;
- enable one extension at a time. Again, be certain that you actually want that extension to be enabled. As with plguins, it's best to keep the overall number of enabled extensions as low as possible. Also, try the theme you want to have installed so see if that is what's causing the problem. When you encounter problems, you know you've found a problematic extension/theme, so disable it for good. Keep enabling all your extensions (except problematic ones) until you've gone through them all. Just the same as with plugins, if you need support for a problematic extension/plugin, you need to contact its author;
- if you've followed my instructions above, you're done! You've fixed your problems with problematic add-ons. If you want to keep using those problematic add-ons, please contant their authors for support.
Ok, now... If disabling all extensions and plugins through safe-mode didn't work to fix your problems (or, in other words, if you've just read number 1 on the list above and come straight here), then you have different issue. The most likely scenario is that you have a third party software running on your computer that is messing with Firefox. Detecting which program it is may be tricky, but the following list should help you. Make sure you follow it carefully. Don't forget to answer the question on the last point, if nothing else helps.
- try reinstalling Firefox. No data will be lost. You can get the latest version (for free, as always) at getfirefox.com. Make sure you uninstall Firefox prior to reinstalling it. For help installing Firefox, see this support article. If that doesn't fix the problem, proceed;
- do a virus/malware check on your computer. See this support article for help on this point. This is a very important step, so please pay attention to it. If your problem is not due to viruses/malware, proceed;
- disable all software running in the background that you don't want to have running in the background (in Windows operating systems, this is done by pressing WINDOWS+R in your keyboard, typing msconfig and pressing Enter; now, under the Startup tab, you can uncheck the software you don't want, and reboot your system for changes to take effect; if you're unsure of what software you want running, ask someone with more experience). If this doesn't fix your issues with Firefox, proceed;
- check if your firewall/antivirus/security suite is conflicting in any way with Firefox's normal behavior. Check for enabled functions/features that you don't want and/or may be causing problems with Firefox. You'll find that these features are most likely tied to Internet Security features, such as link scanners or URL checkers and the like. If you're not sure they are conflicting with Firefox, simply try to disable them temporarily to see whether or not that's true. If this doesn't solve the issues, proceed to the following number;
- check your operating system security options, mainly advanced options that are not configured by default. While it's very unlikely that this may be the cause of the problem, it's remotely possible. If this doesn't work, proceed to the following point;
- update your modem/router software. There have been some reports that some modem/router software may cause Firefox and other browsers to loose performance and/or stability. If updating doesn't fix your issue, try other versions of the software, if possible. If you need support with this, contact your modem/router manufacturer. If this doesn't help, proceed;
- if you are using a Windows operating system, clean up your OS registry using appropriate software. There have been reports that badly maintained Windows Registries may case problems with Firefox. If this doesn't help, see the following point;
- please try creating a new temporary Firefox profile (managing profiles) and see if the issues persist. Please report the results, so we can help you further.
