despite your warning not to mention "ancient web browsers", I have to point out that any browser designed to work on your version of OS X will, invariably, be sluggish.
Since those browsers were designed, web sites have moved on considerably and those browsers do no handle all the new fancy stuff, well.
Does this "sluggishness" happen with all three of your browsers?
I am new here but used to get help at deal mac.
Firefox is acting up... gets sluggish. Please do not yell at me for an old machine and OS and ancient web hrowsers. I am happy thus far. I have limited resources right now.
Will this work to reset my older Firefox?
Go to "Applications > Utilities > Terminal"
