@burnout426 In my settings the option to sync is already unabled so I'll go directly to the second step of your guide.
Now I'll log out from my profile and I'll try to do some modifies to my favorites after that I'll log into my profile again and I'll enable the sync option for favorite to see if the changes previously applied will be synced in the right way,ok?
If not I'll go back to the step one of your guide and I'll repeat all the passages to be sure.
Let me know what you thinks about that ok?

@burnout426 Rectification : After a while (when I was writing the previous post) all my modifies apported were been reverted and now all my favorites disposition in the browser is like it is in https://www.sync.opera.com/bookmarks....
So I think I'll open a ticket with Opera for this bug signalation.
In the meantime how have I to procede ?

Recently I'm having issues with syncronization on my Opera browser,in another post someone counseled me to use that page to check for infos about sync and to try some actions about from it but I'm not able to interprete that page (even if I suppose to have understood something of the functions and infos showed here ) so coul'd you give me an explanation or maybe provide some learning link ?

Why everytime that I change the disposition of favorites in Opera on Windows 10 (I meen for example if I put a folder inside another one) after a little time all the modifies applied suddenly disappear and all is like before the changes??

@burnout426 Thank you !

@burnout426 Ok I've done this: I've logged out from my profile,then I've do some modifies to favorites settings,then I've closed the browser (not deleting the browser activity like I do every time that I close Opera),after that I've opened it again logging into my profile and I've activate the sync option to sync only favorites.
From what I see at now in the favorites pae of my browser (opera://bookmarks/) my modifies seems to had been maintained,but looking into https://www.sync.opera.com/bookmarks I see that the disposition of favorites is different from my actual one...
So what have I to do now? Have I to repeat the action from step 1 ?
And again it could depend on the constant deleting of my browser activity ? If it is the case let me show which options I've enabled to delete when I use that option (look the screenshots)

You can file a bug at https://opera.atlassian.net/servicedesk/customer/portal/9/group/11/create/6 and post the bug number here.

Infact I've opened a ticket with the Opera's assistance to the issue using that form but which is the bug number ? I've receive a mail of confirmation that is signed with that code BS-88386 I suppose that this could be that "bug number" that you're saying (excuse me for my ignorance -.-" )

Suddenly I don't know why all the pages I had left open in Opera by selecting the appropriate option in settings disappeared, there were many and unfortunately I didn't save them in bookmarks or in any other way, so I don't remember exactly what they were. I lost a lot of research I was doing this way. I tried to restore from a restore point prior to the date of the fact, but without results.
I also received an error message from Windows informing me that the restore was not possible due to the antivirus, I then contacted the antivirus support who provided me with possible solutions, here is the guide: https://www.bitdefender.com/consumer/support/answer/1822/ , https://www.bitdefender.com/consumer/support/answer/9513/
Unfortunately, I haven't been able to fix it with either of the two methods listed for the time being, and I'm waiting for more information from antivirus support. So for the moment even if I restore from a restore point prior to the date on which the problem occurred, after restoring by opening Opera the previously opened pages are no longer present...
Also after one of the attempts made by opening Opera to check I received a message informing me that one of the extensions had been disabled because it was corrupted, however I could not figure out which one it was.
At this point could you tell me if there is a way through which I could return the browser to the previous state in which all my searches were present by opening it??I'm thinking of restoring from a disk backup that I saved in an external hard drive, do you think it can be a solution? I would lose a part of the research done but at least not all of it...
Please let ne know!

@burnout426 yes,but if I make a change into my favorites disposition and then I sync them,than shouldn't have I the changes applied also on the synced datas on Opera's servers?

@leocg said in About Secure DNS function:

@Simone-Brunacci Something like https://cloudflare-dns.com/dns-query

Looking in Settings :
I'm already using DNS over HTTPS (Cloudflare's one for malware and adult content) ..
Anyway I've taken a look here and here,and I've done some test to see if it is working correctly :
here's the first result using the Cloudflare's website to check if the DNS is working : with Opera VPN enabled ; with Opera's VPN disabled
Plus I've done soe test using DNS leak test
Opera VPN enabled :

Opera VPN disabled :

So this means that DoH doesn't works with VPN enabled ?

@leocg ok,perfect

I've installed some times ago an extension for translation (at now is called ImTraslator,before it was named Google Translator it seems to me,I don't know why it have changed name,it is the same one on my opinion),sometimes ago I've noticed that it didn't worked well anymore so I've disabled it..how have I to uninstall it correctly ? And how could I know if there was any issues/corruption with it ?
I've noticed the first issues after the name switch,after that I've tried to use it like I was doing before but it was broken on my opinion,for example contextual menu for it's functions didn't worked anymore and either it's settings were not shown correctly or not shown at all..at now it seems to work (apart for some options like inline translation and popup bubble) but I still think that it could be better to reinstall it ..

@clarkbruce said in About Secure DNS function:

@Simone-Brunacci
Here are some dns over https address

https://dns.cloudflare.com/dns-query

https://dns.quad9.net/dns-query

https://dns.google/dns-query

Thank you,if I'm using for example cludflare's dns on my router or pc and I set up the option to use dns over https in the browser, which of the settings will prevail on the others?

@Alexaali Thank you,I'll let you know how it goes !

@leocg I've done that,I've written a post for this on Opera subreddit,if you want to check the updates that's the topic : https://www.reddit.com/r/operabrowser/comments/1fjdkgl/all_open_pages_disappeared_i_had_selected_the/
I've to try to follow the instructions in this one..

All'improvviso non so perché, sono scomparse tutte le pagine che avevo lasciato aperte in Opera selezionando l'opzione appropriata nelle impostazioni, erano tante e purtroppo non le avevo salvate nei segnalibri o in nessun altro modo, quindi non ricordo esattamente cosa fossero. Ho perso un sacco di ricerche che stavo facendo in questo modo. Ho provato a ripristinare da un punto di ripristino antecedente alla data del fatto, ma senza risultati. Ho anche ricevuto un messaggio di errore da Windows che mi informava che il ripristino non era possibile a causa dell'antivirus, ho quindi contattato il supporto antivirus che mi ha fornito delle possibili soluzioni, ecco la guida: https://www.bitdefender.com/consumer/support/answer/1822/ , https://www.bitdefender.com/consumer/support/answer/9513/ Purtroppo non sono riuscito a risolvere con nessuno dei due metodi elencati per il momento e aspetto maggiori informazioni dal supporto antivirus. Quindi per il momento anche se ripristino da un punto di ripristino antecedente alla data in cui si è verificato il problema, dopo il ripristino aprendo Opera le pagine aperte in precedenza non sono più presenti... Inoltre dopo uno dei tentativi fatti aprendo Opera per controllare ho ricevuto un messaggio che mi informava che una delle estensioni era stata disabilitata perché corrotta, tuttavia non sono riuscito a capire quale fosse. A questo punto potreste dirmi se c'è un modo attraverso il quale potrei riportare il browser allo stato precedente in cui erano presenti tutte le mie ricerche aprendolo??Sto pensando di ripristinare da un backup del disco che ho salvato in un hard disk esterno, pensate che possa essere una soluzione? Perderei una parte delle ricerche fatte ma almeno non tutte...

Oltre a ciò seguendo alcuni consigli del supporto antivirus, dopo il ripristino del sistema ho cercato nella cronologia di Opera ma queste ricerche non c'erano più, gli stessi risultati che ho avuto usando l'opzione per aprire le ultime schede aperte (https://www.chimerarevo.com/guide/ripristinare-schede-browser-264827/), in più ho cercato questo percorso: "C:\Users\YourUsername\AppData\Roaming\Opera Software\Opera Stable" cercando i file denominati: "Ultima sessione" e "Ultime schede" ma non ne ho trovati... Potreste aiutarmi in qualche modo?

Please let ne know!

In addition to that following some advices of the antivirus support,after the system restoration I've searched in Opera's history but these searches there weren't anymore,the same results I've had using the option to open the last tabs opened (https://www.chimerarevo.com/guide/ripristinare-schede-browser-264827/),plus I've searched this path : "C:\Users\YourUsername\AppData\Roaming\Opera Software\Opera Stable" searching for files named : "Last session" and "Last Tabs" but I've founded none... Could you help me in some way ?
