Why does FF continue to slow down as I use it, inspite of using Alt-M and re-setting notification timer for 3 minutes

FF always slows down as I use it. I changed the free-memory minimizer to 3 minutes instead of the default 5 minutes and it does not help. I use Alt-M manually and it does not help. The only way to get full response speed back is to close FF and reopen it frequently. I have Win 8.1 (64) / 8 MB RAM. It is slowing to a crawl as I write this.

Start Firefox in Safe Mode {web link} While you are in safe mode; Press the <Alt> or <F10> key to bring up the tool bar. Followed by;

Windows; Tools > Options Linux; Edit > Preferences Mac; application name > Preferences

Then Advanced > General. Look for and turn off Use Hardware Acceleration.

Poke around safe web sites and see if there is still a problem. Then restart.

It could be the work of one of your add-ons, or even add / mal-ware. Look thru your add-ons list and make sure you know what each one is there for. Also, check the programs that are on your computer

Windows: Start > Control Panel > Uninstall Programs. Mac: Open the "Applications" folder Linux:

  • Ubuntu Unity {web link}
  • Xfce: Applications Menu category sections
  • options depends on the package manager and the desktop environment

Go thru the list. If you find something that you don't know what it is, use a web search.

Also make sure that your security software isn't causing this issue.

It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full, unrestricted, access to internet for Firefox and the plugin-container process and the updater process.
