Opera 12 security
As our old Opera is ageing we have to take a bit more care with how we use it. It is already a little lacking, and the defaults MUST be changed, such as enabling TLS 1.2 and 1.3 Looking for some info on extended settings, I found an excellent resource with all the important settings explained http://anonymous-proxy-servers.net/wiki/index.php/Opera_Browser_en http://anonymous-proxy-servers.net/wiki/index.php/Opera_Browser_de If you want an alternative user agent string to put in the custom user settings you can find one here; http://www.useragentstring.com There are occasionally some advantages to spoofing as GoogleBot or Bing etc. as they can often access closed forums and sites.
Some of the settings might break some website layouts, so you should know what you do and how to revert it. Best if you save a copy your operaprefs.ini (can be found in %appdata%\Opera\Opera if you use win and a default install) before tampering with the settings: That way you can always compare and revert settings afterwards.
Very good point.
Yes unfortunately tightening browser security too much can break many sites.
I should point out I have not set my browser that tight, but found the page useful for explaining the use of certain features.
I don't require that level of anonymity, and am more interested in malware protection.
However as this forum is "Private Browsing" I thought others may like the anonymity options.
Hopefully this thread will turn into a more normalised list of options useful for a wider audience
