Vivaldi Snapshot, Win10 21H2

@barbudo2005
as @slysnake96 already said, the problem is the same with your recommended extension manager

If anyone facing this issue still, please delete the paon package immediately.

The reason I am saying this is that, it's a virus which may have come with some file you have downloaded from internet. I have also faced this and it changed lots of things of my browser.

It may sound weird but I was getting lots of weird youtube history which I haven't even watched. besides, there were multiple issues. It normally happen in your default browser/chrome.

So, I have done these steps, hope it will fix yours too...

go to chrome://extensions/ turn on developer option on top right. You will see ID of that extension (sheets)

I have already deleted it, so using an example here
then goto C:\Users\USERNAME\AppData\Local\Google\Chrome\User Data\Default\Extensions and delete that folder named with same ID

goto shortcut of all the browsers and see if target seems right to you. for example, chrome will be "C:\Program Files\Google\Chrome\Application\chrome.exe" not C:\Users\USERNAME\AppData\Local\Packages\Rnews or something like that. change target to correct directory and save. also goto startup C:\ProgramData\Microsoft\Windows\Start Menu\Programs and check other browsers shortcuts

at last goto C:\Users\USERNAME\AppData\Local\Packages and delete the folder. Also if you see any suspicious folder in that directory, scan with antivirus though it wont get caught most likely, but hope that's gonna be enough

I think I figured it out. Typical, once I start digging the solution comes, I just give up too fast 🙂

Seems RPS uses a pseudo-element on the thumbnail element, with some strange clip-path stuff I have no idea what's there for.

.summary[data-size=large] .thumbnail:after { background: #fff; content: ""; ... border: 1px solid transparent; -webkit-clip-path: polygon(0 97%,8% 83%,92% 100%,0 100%); clip-path: polygon(0 97%,8% 83%,92% 100%,0 100%); }

Using pseudo-elements for anything but adding some content is nasty, and so easy to miss when looking at the code... 🤦♂

So this removes it:
.thumbnail:after {content: unset !important;}

Thanks for the encouragement needed to actually invest some time figuring it out 👍

@Jonathan169 Thanks it worked but took 3 attempts could not auto update, had to: back up, uninstall, and re-install with "advanced/all users/".
Now Ubersuggest loads. Appreciate the help.

I personally think to move to Firefox if Vivaldi wouldn't keep and support Manifest 2. I need at least Tampermonkey beside uBO and Manifest 3 kills both.

But that's neither here nor there right now considering Google postponed switch to 2024 and already working on adding user scripts API, so TM might work for me (depending on level of access these scripts will have and ability to start before the page load) and with userscripts it might be possible to work around most of missing uBO features.

It has been fixed by developer 😉

OneTab is really nice, it actually is very similar to my session manager extension, but it still has the same problem, backing it up requires manual exporting. Session managers already allows changing, adding and replacing tabs for different groups, syncing has never been the issue, the main issue is backing up all those groups of tabs that I would have saved in such extensions. If my laptop dies or gets stolen, vivaldi can sync my bookmarks, passwords and settings, but not all the dynamic tabs that I have in the extension.
There doesn't seem to be anyway to do automatic backups for such a scenario 😞

Oh my god it works perfectly! Thank you very much for being patient with me. The Help Page has it all there ( https://help.vivaldi.com/desktop/navigation/start-page/ ), and now I understand it that Vivaldi had long ago provided that option to use alternate Speed Dials.

Now I have the perfect browser! So happy about this.

@adfslasdgiksda
Hi, if you have an extension as .zip file you can open the extension page with Ctrl+Shift+Esc and drag/drop it from the file manager to the Vivaldi page. You need to have the developer switch on.

@eugenesv LOL, my old UserJS url2title from 2006 does the same and works nice.
Just download, save as url2title.user.js, open Extension manager, activate Developer mode, and drag file into extension manager on extension icon in middle of page to install.
Will never be removed by troublesome Chromium extension management, Chrome & Co. do not use blocklist for userJS, i checked this.

@dubh Vote for Move extension buttons around interface.

@Crabb99 It may be just because you are new, and your reputation points were too low. Now that you have two, you might be able to edit the post. If not, never mind.

If you remember next time, you can submit a new topic as a question, and mark it as resolved when a suitable answer is given (if you find one for yourself, mark your own reply as the correct answer).

@Pathduck
Have sent them a query.
Thanks.

This may be fixed, at least partially, in 5.4. You can visit the bookmarks, calendar, history, and notes pages with the new tab page set to controlled by extension, but the startup options might still be broken.

You can use the startup option Last Session without issue and Homepage and Specific Pages as long as they aren't the start/new tab page. Using the Start Page option or setting chrome://newtab/ as a specified page will lead to a startup with a blank page, but all new tabs work correctly.

Might need a new bug report since it is a new broken behavior.

@Pesala: done, thanks for the description. 😉

@DoctorG: I was doing that already before reading your response, but thank you as well.

@DoctorG There are no YouTube downloaders in the Chrome Web Store. You're not supposed to download YouTube videos, so they don't allow them in the Store.

There are some you can install outside of the Store though. You just have to search for them.

Tested with that extension. When the Vivaldi "new tab page" is set to be "controlled by extension", these bugs happen...

The address field doesn't auto focus after opening Vivaldi.

The extension doesn't show in private window, despite setting the extension to "allow in incognito".

When opening a secondary normal window, the extension doesn't show in the first default tab.

Please fix.
