Using TAC 4.0.1 in Fx 64.0 in Linux Mint 18.1. I'm not sure, but guessing the same reason is causing TAC not to save entered text on https://support.mozilla.org/. Has anyone checked if NoScript is somehow involved? Most of the Mozilla sites are whitelisted by default in NoScript 10.x (quantum). What else NS does for specific sites, can't say.

But, I totally disabled NoScript 10.2 in Fx 64, disabled uBo on support.mozilla.org's site, reloaded the site, and TAC still doesn't save text there. This has gone on for some time on the Mozilla site. So unless it's a very unusual way that NS or uBo could interfere, when they're turned off or disabled on a site, it appears to be something else.

I've read some sites (banks, etc.) give instructions to browsers NOT to save entered data - for safety. But they were talking about the browser, not an addon. I'm not that much of an expert to know if that could be the issue here.

I looked at the support.mozilla.org page source code - didn't see anything about "don't save..." but I really don't know what to look for.

I think WebExtensions will not work on mozilla.org. This was a Mozilla decision.
