Before I download, I need to know the file size of the update because I have a bandwidth restriction.

approx 25mb

I will be curious to see if this question is answered because no previous questions have been.

https://support.mozilla.org/en-US/user/prairyk indicates you haven't asked any previous to this

The previous question which I referred to was through support—and I find Mozilla/Thunderbird support very poor indeed. Seems the only way to get an answer is through the forum here. Thanks, for this answer, Wayne. I think the file size should be listed in the product's description.

Not likely to happen on downloadload pages because file sizes vary by local, version and OS. Firefox shows the file size when it asks you whether to safe the file before it is downloaded. (Typically the only time file size will be greater than 10mb is when updating major versions, like from 31 to 38, and 38 to 45.)

"here" is https://support.mozilla.org/en-US/questions

So what do you mean by the other location "Mozilla/Thunderbird support"? Do you have a URL?
