When Firefox is running, the memory usage continues to grow without stopping until windows begin to drag as if I were really taxing my computer and internet, when I'm not. I also cannot download anything through Firefox, unless I reboot my computer to Safe Mode.

I have run through all of the tutorial/knowledge trouble shooting. Cleared all my history cookies, changed folders, removed extensions, disabled plugins, Refreshed Firefox, use the Firefox Safemode. None of it has changed anything.

I can use Chrome to download just fine, even when my computer is not in Safe Mode.

This all seemed to start within the last 4 days or so, and I remember that Firefox made me update about then. My laptop does not have the update and Firefox works fine. I'm currently at a loss. I prefer Firefox, but I have to use a different browser in order to continue working. My business is heavy with internet communication and this has been a nightmare. Until I hear back, I will begin setting up preferences in Chrome. Hope someone can find a solution. [Windows 7prof 64bit]

I'm not sure what you mean by "changed folders," but have you tried this:

Clean Reinstall

We use this name, but it's not about removing your settings, it's about making sure the program files are clean. As set forth below, this process does not disturb your existing settings. Do NOT uninstall Firefox, that's not needed.

(1) Download a fresh installer for Firefox 37.0.2 from https://www.mozilla.org/firefox/all/ to a convenient location. (Scroll down to your preferred language.)

(2) Exit out of Firefox (if applicable).

(3) Rename the program folder

(64-bit Windows folder names)

C:\Program Files (x86)\Mozilla Firefox

to

C:\Program Files (x86)\OldFirefox

(32-bit Windows folder names)

C:\Program Files\Mozilla Firefox

to

C:\Program Files\OldFirefox

(4) Run the installer you downloaded in #1. It should automatically connect to your existing settings.

Any improvement?

Note: Some plugins may exist only in that OldFirefox folder. If something essential is missing, look in these folders:

  • \OldFirefox\Plugins
  • \OldFirefox\browser\plugins

Unfortunately, I think malware is also a possibility. You can supplement your regular security software with the on-demand scanning/cleaning tools in our support article: Troubleshoot Firefox issues caused by malware. These programs are free and take considerable time to run. If they finish quickly and especially if they require payment, you may have a serious infection. I suggest the specialized forums listed in the article in that case.
