@rekrul Try to use http:// instead of https://

i dunno if this wiil help..

--disable-notifications

@edbj i dunno if Use 'n this Opera flag will help..

Disabling autoplaying videos in Opera by use 'n Autoplay Policy flag..

1 Visit opera://flags/#autoplay-policy

2 Select ‘Document user activation is required’.

3 Restart the Opera browser to apply the autoplay policy.

Note that this won't block autoplaying media completely, as media starts to play as soon as you interact with the page. It helps with opening pages in the background that play audio or video content..

@tartack you do not the N nor the KN edition of Windows..

for peeps that do not know..

Go to Control Panel > Clck Programs and Features > Click Turn Windows Features on or off and look for Media Features.. If it is there, you do not have N or KN..

if Media Features there and not checked in box.. then check the box..

Note - Also under Media Features make sure Windows Media Player is checked..

@tartack said in Opera doesn't play some videos:

@nvmjustagirl I dont have any Intel graphic, all is handled by the Nvidia Geforce GTX 660
I tried to do what you said in your steps, but there is a problem at step 6. : Opera does not appear in the second drop-down menu.

as for step 6 make sure its the reguar install of opera, not sure about Portable Opera..

here is a Better guide that explains the steps better found here

scroll down that page to find steps..

i would select the High performance in step 10..

hope ya get things work 'n soon.. *hopefully..

@tartack could ya answer burnouts queston *pls..

those Intel I7-2600 cpu @3.40GHz are still pretty hot.. 4 core 8 threads but the K version had Unlocked Multiplier great to over/clock lol

umm.. does computer also have intel graphics too ?.. along with the Nvidia GE Force GTX 660..

and is the Windows 10 - 64 bits version 1803 or so..

if so and ya wanna leave hardware acceleration on in opera settings..

ya might could try this..

1.Open Settings.
2.Click on System.
3.Click on Display.
4.Click the Graphics settings link.
5.Use the "Choose an app to set preference" drop-down menu and select the Universal app option.
6.Select Opera using the second drop-down menu.
7.Click the Add button.
8.Select Opera from the list.
9.Click the Options button.
10.Select the High performance option. (If you want lower performance to save battery, then select the "Power saving" option instead.)
11.Click the Save button.

Once you've completed the steps, open Opera and it should now be using your PC's discrete graphics card for rendering tasks.

If you end up experiencing problems, such as high GPU utilization or another performance issue, you can also use these steps to change the Opera graphics preferences to troubleshoot and fix hardware acceleration issues. Bear in mind that rendering issues can also be caused by other problems, such as graphics driver issues. If this is the case, you also want to update your video card driver to resolve any graphics problems.

Note - To Undo - If you want to revert the changes, or you're experiencing other issues,

you can always follow the same instructions, but on step No. 5, make sure to click the Remove button for Opera..

@wrangler11 said in After 1803 and 1809 windows update opera dont load web pages:

opera version is 56.0.3051.36 (latest).I don't have any 3rd party anti virus just clean install windows 10 pro to find out why is that problem persists.I tried without any firewall or defender on also..no luck.Sometimes opera can load pages for a few minutes then struggles to open them and stops.

this part you said (Sometimes opera can load pages for a few minutes then struggles to open them and stops)

maybe try different proxies
