Thunderbird: MalwareBytes Add-On

Recently Malwarebytes offered an Add-On for Mozilla Thunderbird. I added it.

Instead of improving the appearance of spam and such, Thunderbird immediately began presenting me with spam I had not seen before. (I began receiving spam that has appeared daily on my Android phone running AquaMail, that does not have a Spam Filter function.)

Thunderbird's Spam Filter function appears to have stopped functioning. A few moments ago I attempted to remove the Malwarebytes Add-On from Thunderbird. No such Add-On was found. What?

Can you shed light on this for me, and help me reverse whatever has happened?

Thank you, rsw1941

tanstaafi,

Thank you. You're absolutely correct. I added that to Firefox, NOT Thunderbird. Duh.

Other than being absent-minded, another event contributed: Thunderbird went to v.78.2.2 on or about the same day. When I realized that I went back through Settings and attempted to put Spam/Junk email bits back together. Hopefully, that will get better over the next few days.

look in your malwarebytes settings. If I recall correctly they actually act like the virus's they are supposed to stop and inject their own code into the running process. This also has a side effect of making the program unstable and prone to freezing and crashing. Undoubtedly it will be like all the times in the past and their addons is simply not compatible with Thunderbird 78 which drastically restricts addons access to the programs source to try and reduce the instability these type of things cause.

I've used the commercial version of MalwareBytes for Windows for about 9 months and it doesn't seem to have caused me any problems. I used the free version for years beforehand. The only other security software I run is Windows Defender.

I'm not aware of MalwareBytes offering an add-on for Thunderbird and can't find any mention of it on their web site or by googling for it. What is it called? They do have one for Firefox (Malwarebytes Browser Guard).
