@mjz2325 Unfortunately, in my experience, trying to get any sort of support from Facebook is a waste of time. You never even get a response or even an acknowledgement of receipt from them. In fact, it's several years since I tried to get help, and I doubt if it's even possible to "contact" their support any longer.

@leocg I thought the extension called "Super Auto Refresh" worked. At least it seemed to reduce the frequency of refreshing, but now I'm finding that Facebook still refreshes annoyingly often. I find this really annoying! If, for example, I am reading comments to a FB post and one of these includes a link that I want to check out, when I come back, FB automatically refreshes and I have to search to find the post I was reading!

I installed this because I wanted to STOP auto refresh in Facebook and it seemed to be the only extension that had such an option. At first it seemed to at least reduce the frequency of refreshing, but now I'm finding it really doesn't work at all.

@leocg Thanks for your response. Yes, I had noticed that this was a solution that's suggested online, but I couldn't find an extension in Opera. Now, thanks to you, I looked a bit more closely and realised that I had misunderstood the Extensions page. I was using the search field where it says "Search extensions" at the top, and was finding nothing. Now I realise that this only searches the extensions that are already installed. To me that seems a bit pointless, as I only have a couple, but maybe other users have a lot more? Anyway, I now remember that you have to click "Get more extensions" first, before searching! When I did so, I found several auto refresh extensions. Most of them seem to be for setting up auto refresh after a certain number of seconds or minutes, but I found one that has an option for "no auto refresh", and set that up. And sure enough, Facebook now only refreshes when I ask it to (by clicking on the "home" icon).

I'm trying to to turn off Facebook's annoying auto-refresh feature. I have searched for a solution online and all the solutions either assume you are using Opera on a phone (which I'm not: I'm using a PC) or, as is almost always the case, the instructions provided online describe a procedure (either in Facebook or in a browser) that isn't possible because at some point you will be told to do something that is impossible because an item you are told to click on doesn't actually exist!
Does anybody know of a way to turn off auto-refresh that actually can be done?

Here's an update. I sent a bug report to Opera and received an acknowledgment e-mail saying that they could respond by e-mail but had noted the issue. I don't know whether they actually did anything about it, because I haven't been notified, but after a week of using a different browser and missing Opera, I tried again today and now find that I can print web pages from Opera, as before.

Since setting up a Lenovo Thinkpad T480, I find that I can no longer print web pages in Opera, as I was able to do with my previous PC. Pressing Ctrl-P results in the message "Print preview failed" and everything in the dialogue box is greyed out. What is causing this and how can I set up Opera so that it will print on a Canon Pixma TS 3420?
I've tried printing from MS Edge and this works fine, so It seems this is a specific Opera issue.

@leocg Aha! I've found that setting now, and it works. Thank you for making me aware of this!

@leocg I didn't know there was any such option. Where do I find that?

If the VPN is active, searching in DuckDuckGo is blocked. Whatever I search for, I get the following message:

What's the point of a VPN if you can't browse while it is active?
