Issues with Firefox

by Early4 / March 1, 2007 1:23 AM PST

I just upgraded Firefox today. Nine times it has frozen and stopped responding.

Any ideas what would cause that and how to correct it?

I've had some issues before

Can I ask your operating system and your system config?

I've had issues with Firefox working on old versions of Windows. Your crashes could also be caused by a lack of memory.

I have Windows XP and I'm not at my computer right now (at work) so I don't know the system config. Could post them later today.

I know I have plenty of I don't think that's the issue.

firefox not responding

In reply to: Reinstall?

i have the same problem with firefox not responding far too frequently. ive uninstalled and re installed several times and even installed a previous version was running 3.5.3 now running 3.5.2 which is now worse.
i have 149 gb with 54gb free. i have a feeling it may be my ram i think i have 2gb and have used 1.95gb. if this is so what would you recommend my next step to be? thanks in advance from a frustrated learner

I would start looking at that RAM usage.

In reply to: firefox not responding

If you have 2GB of RAM installed and 1.95GB is used, then that's a lot. The RAM is there to be used of course, but not that much continuously on any normal everyday system that we would use.

That usage needs to be investigated. If you are using Windows, (you didn't say), open up the Task Manager, (right click the Taskbar, select Task Manager), click the Processes tab, and look to see what processes are using up all the CPU usage time. CPU usage isn't exactly the same as RAM usage, but if any process is using a lot of the CPU's time, that could be an indication of problems.

If that Processes tab does not show a column for CPU, goto View > Select columns, and select CPU Usage. To help identify which processes are using most of the CPU time, click the CPU header column twice. See what is there and you can research that process.

Also, check what size the Page File is. Also called Virtual Memory, it is recommended that Windows should manage it, but sometimes that is changed and a manual size limit is set. If yours is like that, return it to System Managed. The advice in the link below will help;

Often excessive CPU usage can point to malware. What do you use as your firewall, anti-virus and anti-spyware utilities?

One more thing. How often is this computer rebooted, (restarted or turned off, then back on)? Some users never reboot, and I often find they have RAM problems as the RAM never gets cleared.

The RAM usage is reasonable

In reply to: firefox issues

My own Firefox is using 120,000 Kb at the moment, so that RAM usage is not bad.

But the CPU at 99% is. That shows a problem, and like you say, it could be an Add-on, or it could be a particular web site you are currently viewing in the browser. It may be that Firefox has become corrupted in some way, but we will leave that possibility until later.

I see you have removed a plugin. It won't be an ActiveX plugin as only Internet Explorer, (or the browsers with different names but based on IE), use ActiveX because that is Microsoft's own type of plugin. Firefox and other 3rd party browsers do not use ActiveX. But if disabling that plugin solves the problem, then that is good news, and an easy fix. The only 'not so good' news is if that plugin is required to enable you to play that bridge game.

You could try uninstalling that plugin, restarting Firefox, then revisiting the site where you play that bridge and let it install the plugin again. May be it has been updated, or perhaps installing again will solve the CPU usage symptom.

If you still have high CPU usage problems, try this test;

Goto Start > Run, type in either;
* firefox -safe-mode
* "C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode
whichever works.

That will open Firefox with all add-ons and plugins disabled. See if CPU usage remains high like that.

I have had a problem with Firefox for sometime now. I have 3.5.2 which I thought was the problem. After reading this thread I removed and re-installed it two different times and even loaded a previous version. and still have the problem.
It is slow, hangs up and I get a lot of "Server can't be found" errors.
I also have IE8 on the computer and that works great.
I like Firefox better, but am about ready to remove it and leave it off my computer as it is starting to be just too much of a hassle.
My computer is running Windows Vista 64 bit. Has a i7 920 CPU, 6 gig of tri-channel ram, 506 gig unused disk space so I don't think I have a hardware problem.

i would first of all

In reply to: firefox

consider your Firefox add-ons, and run Firefox in it's Safe Mode configuration as I showed above.

If that runs well, then that points to add-ons and/or plugins.

since disabling the "yahoo active x bridge addon" in firefox tools it seems to be working alot better. however, it hasnt totally solved it. but the "not responding" is definatly less frequent. also now in the task manager process list the firefox cpu is 00-01 and running at 144k. the cpu usage below the list is also nice and low flicking around 12% i have just hotmail and this page open. the comp is also running much quieter. i am thinking the yahoo active x plugin bridge was the culprit. will keep posted how my pc runs in the near future. thanks for your help and time mark its been very much appreciated. this site is proving to be a bible to absolute beginners like me. keep up the good work and keep it free lol

Glad we could help

and let us know how things go.

I don't think we addressed your first question about the total RAM usage specifically, but may be sorting out the CPU usage is the key with yours.

Good luck.

hi just to inform you my cpu usage at 100% seemed to be because of shockwave flash plugins. disabled shockwave flash and comp is running like a dream

Ahh, in that case

In reply to: firefox eating cpu

I would uninstall Adobe's Shockwave, and reinstall it. That should solve the problem.

Adobe has advice about this;
How to uninstall Adobe Flash Player

And Install Adobe Flash Player.

If you are using Firefox's latest browser, v 3.53, it should alert you if the Adobe Flash plugin is out of date.
