This is for those using the Opera Web browser and the Tampermonkey add-on to run UserScripts. This week the Opera store wrongly pushed an incompatible update for Tampermonkey, which broke this vital add-on for running UserScripts in your browser. Windows 7 users will now need to copy certain folders, so as not to loose their scripts. Then install Tampermonkey Legacy, and only then uninstall the old corrupted Tampermonkey. It's all explained here, with links. Tested and working.Tampermonkey extension stopped working on Opera . Issue #2297 . Tampermonkey/tampermonkey . GitHub

One more fix. After the above, go... Opera extensions page / Tampermonkey Legacy / and tick "Allow access to search engine results". Otherwise your UserScripts will not run on DuckDuckGo, Google Search etc.
