As a user of Firefox, I was pleased when I installed the latest update. Then I quickly found the down side; NoScript was no longer working and I was horrified at the time taken for these pages to load.I was looking for a vacuum gauge recently and now Google is hijacking the top 3 or 4 inches of each page with advertisements for vacuum gauges and each page takes an age to load, presumably while Google looks up my recent search history, then contacting the relevant potential suppliers etc etc.
The good news is that NoScript now has a version compatible with the latest Firefox, so a fix will soon be organised!
