I have downloaded and used Adblock Plus so far without problems with Chrome - installation was simple and the advantages are obvious.
I have downloaded IE 11 as a backup and wanted to do the same by taking Adblock Plus from the IE 11 "Gallery". Much more involved: You have to download, save and run it as if it was a new program (which it seems to be). Then in spite of several attempts it won't run /install - something to do with the time certificate being out of date (most unhelpful). Then to cap it all Avast comes on warning that Adblock Plus is a dodgy program that ought to be removed - even though at present it is no more than a stored exe file awaiting activation!
What is going on - is Adblock Plus just incompatible with IE and is there something else that does the same job and works??? The choice in the IE Gallery seems to be much more restricted than with Chrome
