If the extension "Feedbro" is opened in the tab, then the tab icon of Feedbro disappears.

[stardepp]

@Gwen-Dragon Yeah, I'm using Sync. Should I delete my sync data and reactivate sync after a Vivaldi restart?

[Pathduck]

@stardepp You need to look in the Elements tab of the devtools, not Console... but it should open there if you Right-click > Inspect on the missing icon. Or click on the next icon that works, then find the Feedbro element in the html above it. Complicated, I know, sorry...

Another idea:

• Close Vivaldi.
• Backup Vivaldi profile folder Vivaldi\User Data\Default\Extension State
• Delete the same folder
• Start Vivaldi

This might reset your Extension icons, but also it will probably reset their hidden/display state. Do at your own risk, that's why we do backups

[stardepp]

@Pathduck No problem...

The other idea I implemented, just like you described, by still hiding the Feedbro icon.

[Pathduck]

@stardepp I have no idea why devtools won't show the correct place. Are you right-clicking the extension icon on the toolbar? In your screenshot you are looking at the tabs-bar.

It should look like this:

@Pathduck said in Tab buttons of extensions are hidden:

...Sorry, I'm sorry, yes I clicked Feedbro's tab... I'm doing it right now...

Finally...

Yes.
It looks OK, the image is there. Try:

• Right-click on the link in "src=" and choose "Copy link address"
• Then paste this in the address bar, Enter.
• Does it show the icon?
• Also paste the string here, in a ```code block``` so we can check it as well.

I assume the number in button-badge the (blue) number of unread feeds?

[stardepp]

@Pathduck Yes, this link shows the Feedbro icon:

I hope I put the string right in the code:

@stardepp OK good. But I don't understand - did you not say the Feedbro icon was not showing? Because in your screenshot it's right there, below the number 4870:

I'm confused

[stardepp]

@Pathduck Ok, I'll explain it again in detail: Feedbro is displayed correctly in the extension bar.

The tab icon of Feedbro is not displayed in the tab bar, that was my original problem. Green arrow in picture:

[Pathduck]

@stardepp Hergot! :smiling_face_with_open_mouth_closed_eyes:

Sheesh, I misunderstood completely, and I think the "dragon" did too

I just read "extension" in the first post and didn't realise they were pinned tabs... we've been looking at the wrong thing the whole time, no wonder you were confused as well when I asked you to right-click the extension icon

That one should just use the regular, web-based favicon. You know the drill by now, and familiar with the inspector mode, just have a look at the tab icon and find out what's wrong

[stardepp]

@Pathduck I apologize again. My native language is German, maybe it wasn't translated well, but I use DeepL...the best translator...

In inspector mode I could only find this one:

[Pathduck]

@stardepp Don't worry about it, I definitely see the humour of the situation

So, same thing there, but open the span above where you are in that picture, with the "favicon" class, and look at the srcset attribute of the image.

Copy the URL from the inspector and try to open it.

[stardepp]

@Pathduck

chrome-extension://mefgmmbdailogpfhfblcnnjfmnpnmdfa/images/reader16.png

[Pathduck]

And does it open in the address bar when you copy it in there?

[Pathduck]

OK so I installed Feedbro and I can confirm the issue here as well.

The code looks like this:

<span class="favicon jstest-favicon-image">
    <img width="16" height="16" alt="" srcset="chrome-extension://mefgmmbdailogpfhfblcnnjfmnpnmdfa/images/reader16.png">
</span>

This should work, and the URL is a valid image::
chrome-extension://mefgmmbdailogpfhfblcnnjfmnpnmdfa/images/reader16.png

Problem is that the computed size of the <img> element for some reason is 0x0px.

Same problem with the uBlock Origin Dashboard page, similar URL:
chrome-extension://cjpalhdlnbpafiamejdnhcphjbkeiagm/img/icon_16.png

And the Cookie Autodelete options page:
chrome-extension://fhcgjolkccmbidfldomjliifgaodjagh/icons/icon_24.png

The Tampermonkey Dashboard page does not have the issue, and it uses a different image-url type:
chrome://favicon/size/16@2x/chrome-extension://dhdgffkkebhmkfjojejmpbldmpobfkfo/options.html
(difficult to see in the screenshot because the tab is inactive and the icon is dark, but it's there)

So I've had the same issue myself, I've just not noticed because I don't pin tabs, and rarely open them anyway.

Not sure if this is something Vivaldi does wrong for these extension-specific pages, but anyway I think you should report it, and link to this thread/post for the details.

[Pathduck]

@stardepp Another thing I don't understand is this:

In this image:
https://forum.vivaldi.net/assets/uploads/files/1574617477180-2019-11-24-18_40_46-greenshot.jpg

You can clearly see the Feedbro icon left of the Last.fm icon:

But in this image with the arrows:
https://forum.vivaldi.net/assets/uploads/files/1574621186567-2019-11-24-19_43_51-greenshot.jpg

It's gone:

What was the difference between these two times?

[stardepp]

@Pathduck Yeah, that works:

[stardepp]

@Pathduck Ok, when I start Vivaldi, the Feedbro tab icon is displayed, when I open the Feedbro tab, the Feedbro icon disappears after a short time.
