I use Explorer at work because copy-and-paste works better with it for my purposes than Chrome. (I could use Chrome and just open Explorer for the one page I need to C&P from, but I don’t like a lot of things open.)
Periodically Explorer will pop up a box at the bottom of the window that says ‘Speed up browsing by disabling add-ons.’ I can ‘Choose add-ons’ or ‘Ask me later’. If I click the former, the only add-on is Adblock Plus. I don’t want to disable that. If I choose the latter, I can choose ‘Don’t disable’. So I’m telling the browser to leave me alone about this add-on. But the annoying window keeps coming back after a time.
Would an update of Ad-block or Explorer fix this annoyance? I’m grasping at straws here. I was gonna ask what add-ons you were running – currently Firefox asks whenever I want to start a Flash plug-in. I have to approve it if I want to play a Flash game. Which is far, some Flash applets are real dogs on a system. But it seems like the powers that be are determined to annoy you until you shut off Ad-Block.
Next time you get that message, click the “Choose add-ons” button. When the window listing your add-ons opens, look at the bottom—you should see “Tell me when the delay caused by add-ons exceeds:” with a drop-down menu. Click that drop down menu, select the highest possible value (10 seconds), and click “Done.” That should help.
