I got this search engine when I switched to Firefox. Both have been working great for me.

A person would have to be nuts not to use StartPage & use it in advanced mode. 25 yrs. with computers & this is the best yet!

** Troubleshoot Adblocker PART II **
REBOOT and return to the BROWSER and then re-install the add-on. Close the browser when complete and after all of the browser processes have closed then READD the add-on, when add-on completes installation of itself then you must close the browser and allow it to restart as normal. If you skip this step the blocker may or MAY NOT complete the process of blocking adds but if you do it will probably function without flaw, since you have installed the latest version from the add-on's author, at this point in time) There are no other focused troubleshooting protocols, that I know of, to resolve issues with this particular add-on. However, problems are quite rare with this browser extension but when they happen they are a simple matter to clear and if you simply leave everything proceed normally, then the browser and add-ons will likely self repair; such as through normal browser process cycling or system reboot. I have had memory of this particular browser add-on acting lively and allowing adds but they are rare and long periods of time will pass before it occurs again. There have been 1 or 2 times where a repair of the add-on became a necessity since the add-on was passing large volumes of ads that were causing slowness and disruption to operations, ie booting, sleeping, restarting browsers, etc. alone they may indeed complete the repair operations on its own. I doubt that anyone will find themselves in this situation but if you do then please contact me so that I may have the opportunity to assist you in completing diagnostic operations with your PC, browser and the add-on.
Consider focusing on any SYSTEM VARIABLES, temporary directories, registry entries, PAGEFILE.SYS, searching file system for errors, rebooting and power cycling. If you've done everything else than pursue the PC system health and/or browser reinstall. Getting to a stall point like this is exceedingly rare and will likely not occur but the only real rule with PC's that you should keep in mind for yourself and that is that PC's will never actually demonstrated absolute ordered predictability is that you can never expect them to behave like a human being but if you keep your OS in a maintained state it will not fail and leave you hanging from a cliff' ledge. That said, of course feel free to contact me at any time for assistance, all the while concentrating on system repair and/or completing thorough system diagnostics on the filesystems, caches, OS an/or registry. You may also consider reinstalling the browser from the authors website.
