Make git public. You stated license is - Mozilla Public License. Don't lie to people, private gits is not public. People have to be aware of what is inside the code used in this extension in convenient way - for security matters. It is good practice to publish code so people can inspect code and submit bug reports.
Make repository public or I will register 500 Firefox accounts and give 1 star to this extension.

No, I actually won't. But otherwise I won't use this extension either. Someone will make an alternative with good and friendly presentation for users.

Exactly the extension I was looking for.
This damn interface is designed for mobile and doesn't take PC users into account, there isn't even an option for that. I'm sick of these corporations spitting on PC users and monopolizing only the center of the screen.

thanks you for your plugin, maybe add a screenshot
to reassure future users of the expected results.

also, do you have a github? it would be interesting to share with others who have had the same idea as you, wouldn't it?

it just works

Works - makes it wider, the end 10/10

Works great when the sidebar is open, nice wide area to read. Does not work when the sidebar is closed, however readability is still so much greater even with the sidebar open, that this gets a 5/5 from me.

Really nice i love that kind of feature, BUT it crunch back when the sidebar collapse :)

- update 29 november 2023:
it work on a "new chat"
but when i switch from one chat to another,
it crunch back the body width of the answers
(only the text field keep it wideness"

+ i don't have any other extension that could overlap

Works again after recent update. Thank U

⭐⭐⭐⭐⭐

update: working in both views now. 5 star.

It extends the page nice. Would be perfect if it also extended the page when the left-sidebar was hidden. Currently it only widens the answer window when the left-sidebar is on view.

It's actually a good Add-on, tnx
