Ublock 1.24.2 does not work properly on Thunderbird 68.2.2 (64-bit)

[WPFilmmaker]

Prerequisites

• [x ] I verified that this is not a filter issue

• [x ] This is not a support issue or a question

• [ x] I performed a cursory search of the issue tracker to avoid opening a duplicate issue

• I tried to reproduce the issue when...

  • [ x] uBlock Origin is the only extension
  • [x ] uBlock Origin with default lists/settings
  • [x ] using a new, unmodified browser profile

• [x ] I am running the latest version of uBlock Origin

• [x ] I checked the documentation to understand that the issue I report is not a normal behavior

Description

I could manually download ublock file from FF addon page and install it. I can go into options and do stuff like update lists. It also seem to block ads on rss feeds (however I am unable to verify this as I have js disabled so it might be because of that). However several functions are broken as detailed below.

Steps to Reproduce

Download and install Ublock 1.24.2 on Thunderbird 68.2.2 (64-bit)

Expected behavior:

Ublock works like in Firefox

Actual behavior:

Ublock is downloadable and shown up in TB addon list and from there one can access ublock's options (tbh it is a big improvements since a few months ago it would not even work to that point). As I said it also seem to remove ads (but this can't be verified atm), but it has several issues:

• No ublock icon like in FF shown on the feeds bar (old adblockplus had it for TB pre-60), right click on the feeds bar and 'customize' does not show any ublock icon to add, so it is simply not there.

• The only way to interact with ublock on a feed page is to rich click on an object and the popup 'block element' appears however it does not do anything.

• Because ublock icon is not present there is no way to manually use the picker, enter zapper mode and other options. Options can be entered only on the installed addons list in TB options.

Your environment:

Ublock 1.24.2 on Thunderbird 68.2.2 (64-bit) on Lubuntu 18.04

No ublock icon like in FF shown on the feeds bar

What is "feeds bar"? Screenshot? uBO button is added in main toolbar. I don't think WebExtensions will be able to put buttons anywhere they want.

The only way to interact with ublock on a feed page is to rich click on an object and the popup 'block element' appears however it does not do anything.

I don't see uBO entry in any menu. Only button in toolbar. And, what exactly you mean by "feed page"?

TB 68.3.1, uBO 1.24.0

Ublock 1.24.2 does not work properly on Thunderbird

Because support for WebExtensions in Thunderbird is still a mess. #194

@gwarser Thanks for the reply, I meant that bar (orange square):

Adblock plus used it in TB pre-60 and was very handy, I supposed (expected?I could be wrong) that webextensions could still use it, if it is the cause IMHO ublock should be there, if not then it is another story.

Hook up, is there support for filtering embedded graphics/texts/nodes in emails?

Currently, you can only filter an addon store "page" or a domain opened in a new tab with:

https://addons.thunderbird.net/en-US/thunderbird/addon/open-tab/

@krystian3w only for rss feeds displayed as webpages afaik.

An fyi: Tb Bug 1641345 has landed and will be on 78. It fixes web-ex tabs for the shared messagepane browser and makes uBlock badge work on multiple message tabs.

Of course, the toolbarbutton can only be seen on the main toolbar, so it isn't available on content tabs. See BrowseInTab to configure this, and for other useful link things.

[alta88]

Tb Bug 1504475 - Add an API for running content scripts in message display browsers has landed on trunk. It seems it will enable element zapping/picking modes in messages. Perhaps just adding the "messagesModify" permission to uBlock will be sufficient to make it work.

Edit: it's highly likely special handling will be needed for mailnews urls, ie url schemes in ["imap", "mailbox", "news", "nntp", "snews"].

[r-a-y]

TB 78.4 landed with the messageDisplayScripts API to filter email content: https://thunderbird-webextensions.readthedocs.io/en/latest/messageDisplayScripts.html (ignore the part where it says the API was introduced in TB 82, it's in TB 78.4 as well)

Should be roughly the same as FF's contentScripts API, but this is for email content.

Update - To avoid confusion, uBO still needs to implement the messageDisplayScripts API before it will work on Thunderbird.

I see only in right click menu, but option no works, how test working networks filters?

because: ##body a do not hide links on all opened mails.

These addons are not popular to recover few function form old ThunderBrowse:

https://addons.thunderbird.net/en-us/thunderbird/addon/open-tab/
https://addons.thunderbird.net/en-us/thunderbird/addon/browseintab/

[gwarser]

Current stable Thunderbird is 91.1.1, and uBO 1.38 seems to work fine. uBO button is present, Element Picker work.

What else is not working?

[gwarser]

Filtering email content does not work:

this.browser is null ext-tabs-base.js:242
    get _uri chrome://extensions/content/parent/ext-tabs-base.js:242
    matches chrome://extensions/content/parent/ext-tabs-base.js:619
    matches chrome://messenger/content/parent/ext-mail.js:810
    query chrome://extensions/content/parent/ext-tabs-base.js:2074

    from self-hosted:488

   *        @readonly
   */
  get _uri() {
    return this.browser.currentURI;
  }

[gwarser]

New permission will need to be added to support content scripts in messages view: https://webextension-api.thunderbird.net/en/78/messageDisplayScripts.html

Does not work alone, maybe what alta88 said is needed:

Edit: it's highly likely special handling will be needed for mailnews urls, ie url schemes in ["imap", "mailbox", "news", "nntp", "snews"].

[krystian3w]

Also nice will be create file to auto-update addon like this:

gorhill/uBlock@8263351

Gorhill no reccomend put addon on domain:

https://addons.thunderbird.net/thunderbird/
(https://addons.thunderbird.net/en-US/thunderbird/addon/ublock-origin/)

[alta88]

this.browser is null ext-tabs-base.js:242

I've made numerous comments about fixing the Tb tab implementation, for precisely this reason of seamless operation with Fx extensions, and it's been useless so far. See Bug 1649035, for example.

In actuality, this error is likely to be on a 'special' tab type (calendar, chat) or in a transitional situation that may or may not be fatal.

mailnews urls

But this is uBlock's todo, if Tb support is a goal.
