@jamesconstance I get a popup saying "opera doesn't support chromium theme format." How did you get round this?

I used Brave browser

Agree.

I quite like this high contast theme from the chrome web store - it uses a different colour for the selected tab :https://chrome.google.com/webstore/detail/high-contrast-colorful/cdfdkmklcjlnnnlnplffpdiekfhkpbme

It seems to me there should be a permission we can set that can prevent an extension from sending data to any website: without this many extensions can harvest our data and compromise our privacy.

Why is this permission not a standard obvious thing to include do you think?

I also notice that under Clear Browsing Data - there's the option to clear cookies and other site data - and it says 'signs you out of MOST sites'. I don't understand why this option wouldn't sign you out of ALL sites??

Maybe those sites aren't using (only) cookies?

I'm not sure - I'll have to keep an eye on it. Thanks.

@jamesconstance
Should you wish to auto remove cookies when closing the browser, one thing worth considering is Private mode.

Go to the Opera folder and find the Launcher application.
Right click and send a shortcut to desktop.
Right click the desktop shortcut, then left click Properties.
In the target field, add "-private" (without quotes) at the end of the address.
Leave ONE space between the target address and -private
Click "Apply", then "OK" and restart.

Your Opera desktop browser will now always start in Private mode, and when closing the browser it auto removes cookies etc, except for anything which you've saved.
Hope this is of some assistance.

Thanks for the suggestion. Private mode does extra things however, such as remove history - and extensions aren't available.

''Keep local data only until you quit your browser – Deletes cookies that have been added after this preference was enabled when closing the browser.'' -doesn't appear to be working - in that I I find that I am still logged into at least some websites even after I have restarted windows. Thanks

Thanks for your reply, sgunhouse.

I'm looking at the Opera Help file on extensions [https://help.opera.com/en/latest/customization/#extensions] but it doesn't give any information for 3 tick box options on the extension page.

1. Allow on all websites
2. Allow access to search page results
3. Allow access to file URLs

Can anyone tell me what these options do or point me to the documentation?

Thanks

Just wondering how much of a security risk extensions are and whether that risk can be mitigated in any way? The info pop up on the extension in the extensions management page says the extension can access your data on all websites - how do we know that the extension isn't sending all this info to a third party? What is the effect of deselecting the check box "Allow on all websites"? Thanks.

(I didn't receive any answers for this question in the add-ons section, so I have reposted it here).
