Tampermonkey: [Vivaldi] Twitter, Tweetdeck, Twitch not loading properly as long as Tampermonkey extension is enabled

[KillyMXI]

Expected Behavior

tweetdeck.twitter.com shows my decks,
twitter.com/{user} shows user tweets

Actual Behavior

Yesterday the behavior changed to the following:

tweetdeck.twitter.com shows infinite spinner,
twitter.com/{user} shows the layout, but only error and retry buttons in place of content. ("Something went wrong. Try Again.")

browser console shows that all XHR requests to Twitter API are failed with net::ERR_FAILED

Specifications

Vivaldi - 2.12.1843.5 (Official Build) (32-bit)
OS - Windows 10 OS Version 1909 (Build 18363.657)
JavaScript - V8 8.1.307.20

Script

I can confirm the same behaviour. It also happens on twitch.tv.
Requests to https://gql.twitch.tv/gql fail with the following headers:

Seems to affect all POST (JSON) operations.

Vivaldi 2.12.1843.5 (latest snapshot) is based on Chromium 81 beta so I suspect the issue lies somewhere there. But could be worth looking into for Tampermonkey devs for when Chrome 81 is publicly available.

Same problem for me.
Workaround : use Good Twitter extension, and now, Twitter evert to old style but surf is okay

Looks like this is a Vivaldi issue. 2.12.1843.5 is based on Chromium 81.0.4044.41, but Chrome 81.0.4044.43 working fine.

Working fine with

• Vivaldi
  
  
  
  • 2.11.1811.47 (Stable channel) (64-bit)
  
  
• Chrome
  
  
  
  • Version 80.0.3987.132
  
  
  • Version 81.0.4044.43 (Offizieller Build) beta (64-Bit)
  
  

Not working:

• Vivaldi
  
  
  
  • 2.12.1843.5 (Official Build) (64-bit)

Reported to Vivaldi, got issue reference VB-64468.

UPD: Got a response:

Thank you for reporting the issue.

This issue has been confirmed and it has been passed to the team for further investigation.

In the meantine, you should be able to work around temporarily by disabling certain extensions that you have on Vivaldi as you pointed out. Alternatively, we recommend you to use, for instance, a clean profile to view the certain webpages that are affected by this issue. Here are steps to create one:

1. Click on the Profile button in the top right corner of the browser window and select 'Manage People'
2. Click on 'Add Person' at the bottom of the popout menu.
3. Pick a name for the new profile (or leave it as it is) and click 'Add Person'

Hope this helps.
Thank you for being patient with us and for using Vivaldi!

Fixed in latest Vivaldi Snapshot 2.12.1849.7. Tampermonkey is back enabled :)

[KillyMXI]

Yep, it is resolved now.

Relevant line in the change log:

[Extensions][Regression] If an extension uses webrequest it could cause breakage on some websites: e.g. Twitter VB-64275

Thanks for reporting this to Vivaldi.

This issue still exist in Chrome 85.0.4183.102 (64 bit). Websites in the list below:

• https://twitter.com
• https://open.spotify.com
• https://apps.apple.com/tw/app/id425073498
• https://hahow.in

are all failed. Requests URI with api.* are all response net::ERR_FAILED when Tampermonkey enabled.

@howar31 It's not Tampermonkey doing this, check your ad-blocker settings. And this thread was related to a specific case in the Vivaldi browser, not Chrome.

@Pathduck
I'm pretty sure it is Tampermonkey's issue since everything is working good after Tampermonkey being disabled, and error while it's enabled. Tested in incognito mode on fresh installed Chrome.

I saw the symptoms are quite similar so I commented on this thread. Sorry and I'll create a new issue to discuss about Chrome case if needed.

I'm pretty sure it is Tampermonkey's issue since everything is working good after Tampermonkey being disabled, and error while it's enabled.

And so I thought when opened this issue.
It was then confirmed by Vivaldi devs that it was on their side, as you can see from comments above.
It is totally possible Google devs did something similar this time.
(Browser developers are the ones responsible for the API and everything behind that allows extensions to exist, after all.)

Twitter and twitch work fine with up-to-date Vivaldi and Tampermonkey 4.10.

I have the same problem with the latest version of google chrome.
Google Chrome version: 86.0.4240.111 (Build officiel) (64 bits)
Tampermonkey: v4.11
