@burnout426 Thanks very much for your reply. I was under the impression that Firefox was also Chromium based, but I guess not (it does have a Chromium License covering certain pieces of code, but I guess the main browser engine is Mozilla's own). That's a shame.

Thanks for the link, I'll check it out

Hi Folks
I've been using Opera for about a year, and love it. I've been using Zimbra for email for many years. Yesterday evening, apparently out of the blue, Opera stopped showing email body in the reading pane, and it's also not shown if I double click on an email. It's bizarre. I tried rebooting the laptop, clearing the browser cache etc. but nothing changed. I have tried other browsers (Edge, Brave) and they show the email body correctly, so it seems to be an issue with Opera.
Has anybody else come across such an issue? Any ideas on how I might fix it? Perhaps a setting I'm unaware of?
If you need any more details, let me know.
Best regards
Billy

@leocg I just went back and had another look. Ads were blocked on the site, and always have been (even though there are no ads), but when I turned off ad blocking for the site, the email bodies are back. So it looks like I'm good to go. Thanks for taking the time to reply.

@leocg Thanks for replying. Just as stated above, rebooting the laptop, clearing out the 3 options in the Basic clear browsing data option. I'm not sure what else to try.

@leocg Thanks for your help, again - the User-Agent 007 extension did the trick and seems to work great.

@leocg I tried User-Agent Switcher by esolutionsnordicab (first one in the list, and most reviewed), but it did not work to allow me to run the Oracle Cloud software. There appear to be several - is there one in particular you have used and/or would recommend?

@burnout426 Although the command line prompt option worked great for Oracle Cloud, my extensions were not enabled and I am unable to enable them because the Extensions site thinks I'm not running Opera! I guess I'll have to run with different options depending on what I will be doing. Pity.

@l33t4opera thanks very much for the details

@burnout426 Thank you very much for your very informative response - your command line prompt (modified for my launch path) worked perfectly, and I can now use my Oracle Cloud software within Opera.

The extension I had tried was User-Agent Switcher by esolutionsnordicab (first one in the list, and most reviewed).

Is it easy to locate documentation on things like the command line options? I could not seem to find it in the help.

@leocg Thanks for your very prompt response, again. Unfortunately the browser user agent switcher did not do the job. I guess I will have to contact Oracle.

Supported Browsers
Oracle Cloud Infrastructure supports the following browsers and versions:

Google Chrome 69 or later
Safari 12.1 or later
Firefox 62 or later

I'm using Opera Developer edition version 69.0.3638.0 on a Windows 7 64-bit Dell laptop.
Can I tweak any settings in Opera to make it "look" like one of the supported browsers above?

Interestingly, I tried the Brave browser and it seems to be supported i.e. it works.
I don't want to use Chrome or Firefox, but obviously I would prefer to continue using Opera.
