that should say clear the browsing cache.

I think going back these used to be separate but don't quote me on that.
sometimes it would be nice to be able to clear the browsing without that meaning having to log into dozens mof sites again.

anyone with me on this ?

exactly, that's not a playstore download, if you tried more than once and gotten the same message it's probably a good thing as it might be a badly altered file.

@leocg I use operas adblocker AND adaway (which regularly updates host files for spamming pop ups and tabs) and still get those ads that use Javascript (I'm guessing) to keep the page open and sometimes requires a confirmation being ticked before you can even dismiss the tab completely. I think disabling that part of Javascript if that's possible would be a good thing. I've rarely seen it used for a genuine reason by a site.
you still will get these messages regardless of the number of times you've clicked on do not show again.

if you're on a newer version of android you should be able to use the expanded desktop feature on a per app basis. check in settings / display / expanded desktop to see if you can choose. otherwise you'll have to toggle it on and off as needed.

I can confirm the above, after every download opera hangs and becomes unresponsive. eventually an ANR notice pops up so you can close the app. this only just started happening with the last playstore update. I have a HTC one m8 on google play edition marshmallow.

I keep getting an option at the bottom of the screen after typing into a text field offering me the option to search for the terms I've just typed. I want this gone but there's on option in settings for it.

with marshmallow's permissions opera for Android is intended to be able to write to external SDcard. I have all permissions granted in settings/apps and independent of writing to the external SDcard I can type file://localhost/storage/ into the address bar and read any folder on my external SD so it looks like it's an opera side issue in not being properly updated for marshmallow as google has seen the error of it's ways since kitkat.

the strangest thing about not being able to select folders on external SDcard for downloads is that for uploads of local files on the external SDcard there's no problem. because the documents dialogue is brought up you can select a file using in built or 3rd party means and opera will upload that file without any issues.

embarrassing !

zero chance of opera spending time to develop a new browser for a dead platform. nobody anywhere is supporting Symbian, whatsapp are giving up dailymobile has closed so it's time to move on (not to cheap Android though)...
