why does firefox slow down my machine? If I leave the browser open with web pgs open, slow>?

If you have an old version, memory leaks can make it slower as you let it sit.  Also if you have lots of extentions, some of them may slow down.  Try removing some, or  upgrading Firefox.

usually, PC slowdown can be attributed to unwanted programs running in the background. by typing in 'msconfig' in start>run\nyou can select which programs to turn off...\n\nas a useful guide of which things you need or don't need, try answers that work...\n\nhttp://www.answersthatwork.com/Tasklist_pages/tasklist.htm\n\nthis gives a list of processes and what they do, so you can tell if you can get rid of them...

It takes a few seconds before the program loads, but after that Mozilla Firefox runs quickly and smoothly. It is easy to add extensions for pretty much anything you may need. I have one that'll quickly create RSS feeds. And pretty much any browser is more secure than Internet Explorer.

The 1st thing I would do is to delete your cookies and temp internet files. Then I would run a defrag, and see from there.

The most likely cause for this is that your computer's memory, or possibly its virtual memory is too low.  Try running defrag on your hard drive.  You might also try shutting down any other windows or programs that are running.  Other than that, it depends on your processor speed.  If you computer is more than a couple of years old (e.g. it has pentium II or earlier processor) It may be too slow to handle the newer yahoo and other programs.

It's not adblock that slows your computer down, it's the stuff that you didn't block that's searching for the stuff adblock is blocking that's slowing your computer down. Try adblock and script blocks and faster fox for the fastest surfing experience with firefox.

Intriguing indeed. I know what you mean about speed--I have dial-up (my only option due to location) and after I used Firefox, IE suddenly seemed prohibitively slow. It seems that I have become a kind of walking advertisement for Firefox. I've been using FF for a year or two now and I love it more every day.  In that time I have picked up a few extensions and tricks that make my browsing experience much faster and easier.\n\nMy favorite extension is definitely Tab Mix Plus. This extension has an almost overwhelming number of settings and features, so I’ll list a few of my favorites. Tab Mix Plus let’s you merge windows, duplicate tabs (very useful), highlight tabs you haven’t seen yet (great for keeping track of a large number of tabs--I have it highlight the text blue), highlight the currently selected tab (which can make it easier to see which one you’re looking at--I have it bold the text),  and display a progress bar on each tab (since I have dial-up, this is a great feature to let me know how far a tab has left to load without having to leave the tab I’m on--I have it use a progress bar with a white background so I can still read the text). Tab Mix Plus also has an undo close tab feature and a session restore feature; both of which are newly included in FF 2, but I still prefer to use Tab Mix Plus for these (the session restore gives you the option to restore the previous to last session in addition to the last). Any or all of these features can be used, and I am excluding quite a few of them.\n\nI also use and recommend the following extensions:\n\nAdblock Plus; which--when you sign up to a filter subscription (which is absolutely free and doesn’t require giving any information about yourself [in case you’re wondering])--stops most ads on the internet from loading (this is especially important to me since ads take up so much precious bandwidth).\n\nGoogle Notebook; a tool from Google that makes it easier to add notes to your Google Notebook account (which you can get for free and access from any computer with an internet connection).\n\nIE Tab; which--since not every webpage supports FF--can embed IE in a tab in FF. The pages load just as slowly and you are just as insecure as if you were using IE in its own window--but it can make things easier when you’re forced to use IE. IE Tab also lets you easily open the page you are currently viewing in FF in a real IE window\n\nCustomizeGoogle; which can change the way different Google sites are displayed. I use it mostly to remove the ads from Gmail, but it can do a lot more.\n\nDownload Statusbar; which puts a list of your current downloads on a bar at the bottom of the screen.\n\nAnd finally Image Zoom; with which you can easily zoom pictures on websites in and out by holding down the right mouse button and scrolling up and down (most pictures become too pixilated for this to be of too much use, but I still like it).\n\nDon’t forget the search bar! I use it much more often that I thought I would at first. My most often used search engines are: Google (which is included), Wikipedia, FILExt (which tells you what the file extension [such as .exe or .txt] you searched for is used for), and, of course, Yahoo! Answers. \n\nI use the find bar (shortcut: Ctrl + F) all the time; it lets you find a string of text in the page you are viewing very easily. This is especially great when you come across one of those webpages that seem to have no end or means of organization--but really, I tend to use it everywhere.\n\nI love the page source viewer (shortcut: Ctrl + U)--which also has the find bar. If you know HTML you’ll probably agree that it is much better that IE’s page source viewing system (open in notepad). \n\nThe new spell-check-as-you-type feature is nice. If you want FF to spell check a field that it isn’t checking, right-click the text field and select ‘Spell check this field’.\n\nYou can also drag and drop the tabs to reposition them (if find this

Internet Explorer on my CPU does the same thing sometimes. \nTo get around it, right click on the link and select "open in new window".

IE7, Netscape, Firefox (http://www.mozilla.com) are all browsers that use more system resources than IE5.1.  This means it takes more for your system to run them than the old browser.\n\nThis may be a case where in order to run the new software you may need to have a more powerful computer.  What are the specs on your system?

Just go to edit, then preferences.  Under 'General'  check the box to have Firefox check if it is the default browser.  It should do the rest for you.  Unless you're a Linux user (like me), then it all depends on your desktop manager.

Go to www.pcpitstop.com and run its diagnostics.\n\nThis will diagnose whether your problem is:\n- processor too slow\n- not enough RAM\n- disk fragmentation, speed or capacity\n- spyware installed/ OS patches not installed\n\nor a combination of these.\n\nDeinstall any applications you no longer use, and delete, compress or archive any unneeded data.

I like Firefox better for several reasons. More User control: over special sub programs, called "extensions"  over appearance with lots of themes, over popups, java script, and web site redirect stoppers. It loads fast, is highly reliable, and constantly being improved and updated. It sends no data to Bill Gates, loads fast, and is FREE.

Have you installed any programs? Those programs could be running in the background eating up speed. I would recommend you try uninstalling them. Also you may want to download and run an anti-spyware programm. You may have inadvertantly gotten some  ad programs on your PC that could be slowing you down.
