Linda,
Firefox is what I use. I tried Chrome and did not care for it..
As professor trots said, one needs to keep a bunch of stuff from accumulating which is easily done but FF is fast also.
If Chrome works for you, stay with it. ALl of the add-ons you can get for firefox will make your surfing more secure and less problematic with ads.
There are some great ones available and all are free to use.
Worth looking at.
the best,
micro...
