Firefox hanging
This started yesterday. Firefox hangs, using 50-60% CPU and no network
activity. I restored the C drive and MBR from a week ago (Aconis image) and it got better for a little while but it was back. Then I tried refreshing Firefox, same thing, OK for a while then it started slowing down again. There is no particular page activity. Event recorder shows this Warning TCP/IP has reached the security limit... Error ...DCOM got error the service cannot be started because it is not enabled or no enabled devices attempting to start gupdate with argument /comsvc Another alarming info message is remote console app started. I thought I had that turned off. To make matters worse Internet Exploder is broke too so I don't really have a way of comparing them. IE8 says it thinks I have a firewall setting wrong but I turned Norton and Window firewall off still no joy. I am starting to think I have been hacked or that Firefox is the virus. My next step may be to unplug the other drives to be sure they are not infected and putting the bug back on, Format C: and reload with an even older image from a remote drive. See how long that runs OK |

See how long that runs OK Did you install extensions into your Firefox profile? In Google Chrome, extensions can continue to run in the background when you "exit" Firefox. I disabled that featu when I exit an app, I expect it to actually unload from memory (and why I'm still a bit ****ed how Google lets apps continue running in the background in Android). If I "close" an app, I expect it to also exit or unload (unless it is just a frontend GUI to a background process or service that I know about). I don't know if Mozilla copied this "feature" of Chrome: there's just too many settings in about:config for me to waste digging in there. Did you check if Windows is using a proxy? Control Panel - Internet Options - Connections - LAN settings. While Firefox can have its own internally configured proxy setup (menu - Options - General - Network Proxy), it usually uses the system settings; however, check what Firefox is configured to use. Since both Firefox and IE are affected, and if a proxy snuck in, tis likely the global Internet Options settings are used by both and a proxy is defined there. In Windows' settings, make sure all the LAN settings, including for proxy, are unchecked (not used). Some programs use their own proxy. Some anti-virus programs work by have the proxy settings point at their own local proxy, so all network traffic goes through the AV's proxy. It's been a long time since I've seen that method used. Usually the AV uses a transparent proxy to interrogate network traffic. I have a video stream capture tool (Applian Replay Media Capture which is a rebranded Jaksta) that uses a proxy to capture video streams (and doesn't require to play the entire video in the web browser, just to find where is the source and begin capturing it as though it were a separate web browser). I've seen where the AV or RMC proxy has become unresponsive which killed all web traffic (which to many users is the Internet but the web is just part of it). I can kill the proxy for an AV and get it reloaded (but sometimes it's just easier to reboot) and killing the RMC proxy is easy. Killing the proxy won't work if the OS is still configuring to direct network traffic through the proxy (that isn't running anymore). Did you check your 'hosts' file (that it only has an uncommented entry for localhost to go to 127.0.0.1)? Did you try booting Windows in its safe mode with networking and then testing the web browsers? |

This may all be academic at a certain point because time is catching up on this old XP machine and I may be going up to 7, kicking and screaming all the way. I may have a guy sending me 7 pro in the box. |

Disabling an add-on does not remove its settings (that you can see in about:config). While safe mode is a troubleshooting step by disabling all the add-ons, that doesn't change back to default any settings that were changed by the add-ons. That's why the next suggestion is to to create a new profile and load that (make it the default) when you load Firefox. Sometimes uninstalling the add-ons will remove their settings but not always. I've found lingering settings from add-ons that were uninstalled long ago when I happened to do some cleanup in about:config. Since all those add-ons are disabled, you aren't using them, so why not uninstall them. If that still doesn't help, try using a new profile. |

I may have a guy sending me 7 pro in the box. Any site can bog down the client (web browser) by getting stuck in a Javascript loop or waiting for content that doesn't get delivered (for example, by an adblocker that blocks content the script is waiting for, like more scripts from off-domain). You could try disabling Javascript when you visit the target site to do another download; however, that will likely make the page unusable or the download link won't work. I played with it some more and this really seems to be a Java script hang. I am not sure where to go but I assume when I get the gray box I could glean something from debugging the script. I only saw it a couple times but now I am guessing I left the smoking gun on the ground and walked away. |
