If you try to write in the box, or paste using CTRL+V, does it work that way?

Or if you're in the field, would using the ALT menu Edit › Paste work instead perhaps?

No control v doesn't work Its like fire fox doesn't see description box If I use edge and write in it or paste in it Then fire fox sees it and I can paste on top of edge wording

But not anywhere else

Thanks for being concerned

Using fire fox i click inside the description box I get what I have attached.

There are some fixes around the "editable" context menu for a similar site issue, but the inability to start "entering" anything at all, i.e. not seeing the element as editable at all, even for keyboard input, is new and concerning:[

Could I ask for a favor and some help with figuring out how the issues relate if you feel comfortable trying out a non–release version to compare? If you can download the separate Firefox Nightly nightly.mozilla.org that will come with its own clean profile and won't interfere with your normal release, so you can experiment with it safely in isolation — and try creating and editing the listings using this Nightly build to help inform how that's working for you in that experimental version? Thank you!

downloaded. haven't figured out how to get to ebay thanks doug

Right — after installing the separate Nightly, it won't have any of your bookmarks and logins from your release version, it's a clean slate. You'd need to copy&paste the link from your original bookmark or address bar to the Nightly, and also copy or write down your username and password, as the Nightly build won't know any of it.

copy and paste works with nightly
