@rec00k Please try the troubleshooting steps, including testing in a clean profile and disabling adblocking/extensions: https://help.vivaldi.com/desktop/troubleshoot/troubleshooting-issues/

Thank you both of you, Impetuous and in a hurry, I went ahead and copied the entire vivaldi folder over., before I read your two responses. It worked with one hiccup--I lost the only two passwords that I had saved, both for email accounts. I had to reset these--no problem. If I had followed DoctorG's advice, It probably would have gone perfectly. Perfect is an absolute. Something is perfect or it isn't. There are not normally degrees of perfection. But in this case, I can break rules. The migration went mostly perfectly.

@DoctorG Thanks, I kinda figured this came down from Chromium. I will try your posted fixes. Thanks for the info.

@Omnimaxus The report is not even confirmed in the bug tracker and such graphical glitches get mostly low priority. Vivaldi also works just fine with dark tile bar.

I just came back to say that it proved necessary to re-install Linux Mint, which cleared up a number of other problems that had developed with my main user account. I haven't yet re-installed Vivaldi, but I have no reason to believe that the re-installation would not have cured this problem.

@rec00k said in Custom search engines lost after upgrade (since about 5/2025): at least after the upgrade to 7.4.3684.55 (Stable channel) stable (64-bit) on my Linux Mint 22 (XIA), my custom SEs stayed in! Good. be happy.

actually, it was vivaldi all along. They were doing a system upgrade, breakdown, power outage, or whatever it was they called it. i had never been to Vivaldi Status at the bottom of one of the pages i was on and sure enough, it seems that was the problem. Go Vivaldi Go...b³

What do you mean by "change settings"? I can't stand it when people try to push everything onto the user just because the developer can't figure out how to program it properly and doesn't bother with it. But that seems to be normal these days: to throw something together and then leave it to itself. The junk will just fly off the disk again, bug report is clever, it won't be taken care of anyway, so screw it.

@DoctorG It doesn't stop me from using the site so it is no big deal. Thanks

Well, so far it seems to be working. I hope it doesn't fail again. Thanks to both @AlexPortfoy @mib2berlin

@marchernandez Muchas gracias. Mañana lo intentaré

@npro So after comparing most every other flag/extension/etc with a vanilla install on a VM, I found the setting. I should have looked at them first, since a sync caused the same issue. This had to be enabled... Settings/Tabs/Tab Features/Tab Selection/Include Active Tab in Initial Selection I guess it's the price of having so many options. Thank you for the suggestions.

I see!!!! Thank you

Great ! Thank you ! This helped me a lot, when fixing up different computers EMails hierarchies. Sycronizing is much more easy goes smoothly. And "Show folders size".

@Ensio Thank you for an good advice. Now I have fixsed this problem. I build up, same a like, GMail and Thunderbird folders by hand and after that I was syncronizing Vivaldi's GMail.

How many Vivaldi users are in Finland and how many Linux users ? Have you ever thought that we have Forums to debate your attitude to Vivaldi clients.

Now, on both Linux Mint Vivaldi is working. My messing with "Profiles" was one reason. I made "Profiles" newly and berhaps "Vivaldi crash-Team" was also helping me. Now I have to learn new trics with "Vivaldi browser" after "Firefox and Thunderbird" ! "Vivaldi Crash-File" is empty ? I do not know why ?

@acosta01 Ungoogled Chromium works where Vivaldi doesn't. It's my second browser, I'm thinking ab out making it me first. Last few days I've been tracking a couple of packages coming via USPS and the blank page when clicking on a tracking link is driving me nuts. UG always works so I've started not even trying with Vivaldi. I'll try disabling ad blocking and see if that helps. EDIT - I disabled ad and tracker blocking and tried with VPN and still no joy. But it does seem that if i hit refresh continuously the tracking eventually populates.
