I have a hard time deciding between Konqueror and Firefox, but Firefox has so many great extensions that it really is hard to give up. One of Firefox’ best extensions is AdBlock Plus, which blocks ads on websites that you visit.
There is also an AdBlock extension, which is different than AdBlock Plus, and regular Adblock has a downloadable list of blockable items. Getting this list from here, you can then save it to your hard drive and Import it into Konqueror, banishing ads from your browsing there as well. Pretty simple, just:
1. Download the dated .txt file from the site, and save it to your hard drive.
2. In Konqueror, Settings Menu > Configure Konqueror > Adblock Filters (on the left), click [Import] and browse to your file. Done, and much nicer web browsing!
