Adblock extensions have moved on to Webextensions, and hence don't currently work in Thunderbird. The hope is that Thunderbird will include the corresponding API in a future release to support Webextensions. Don't hold your breath though.

Seriously? Mozilla just seriously jeopardized the security of its users with Thunderbird 60.7. Ad Blocker addons are the only thing that blocks malicious scripts from within ad image files from affecting your computer.

This is a GAMESTOPPER level issue, and needs to be addressed immediately!

Gosh! Glad I didn't try to hold my breath for more than three months on this one.

Seriously, ads are part of getting free stuff. I only object to the ones that flash obnoxiously. Maybe I have a bit of ADD, but can't we have an accommodation? I totally can't focus on text when there's a flashing ad nearby. Like, it takes me about ten times as long to grasp the message in the text if it's at all complex...

Sorry to see your thread hijacked by someone that does not know Thunderbird simply does not execute scripts. So what you see is what you get only HTML and images. Most flashing is a gif image, so perhaps block images from the sender or domain in Thunderbird.

Another alternative is to "sanitize the HTML or view it in plain text form. View menu > message body as as pick a format that is not annoying.

Thanks! I'll look harder for these options next time the problem arises.

You may have allowed some remote content to display. Menu icon > Options > Privacy' Under 'Mail Content' section: If you have selected 'Allow remote content in messages' then suggest you uncheck it and only allow remote content for emails you are really certain of source and what remote content they contain.

Click on 'Exceptions...' button see if 'li.seekingalpha.com' is listed, if yes, then select it and click on 'Remove site' click on 'Save changes' click on 'OK'

Wow! I never looked in that list before. There were DOZENS of addresses that had been given permission without my recollection. And "Allow Remote Content" had been unchecked all along. I guess I've been promiscuous in allowing all sorts of sites access. So I deleted them all and await with interest...

How are things at Toad Hall these days?

This isn't true for RSS feeds.
