Zoom applied in private window

[ghost]

I am running a 4k and a HD monitor on linux and it is nearly impossible to set the scale up correctly in the os. Since I use the 4k screen only for a browser window, I tried this addon and it works great setting every site to 180%. Now I sometimes need a browser on the HD screen and it should not be scaled up. I found that your plugin can not be configured seperately across multiple firefox windows, so I tried opening a private window with this plugin disabled.

It works as I want it to mostly, the problem is, when I visit a site that has been scaled up on the main window, for example a search engine, it is still scaled up in the private window and I have to manually reset it back to 100%. When I use the site in the main window again after that and then in the private one, it is scaled up to 180% again.

I saw in the other issues, that it is impossible to set the zoom depending on the dpi, but is it maybe possible to set zoom levels per firefox window independently of one another, or at least prevent the zoom to be set as a sideeffect in private windows?

It's possible to do so https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/extension/inIncognitoContext

But I've lost control over the account I used to create the extension so I can't make any further modifications https://discourse.mozilla.org/t/lost-my-security-code-and-cant-log-in-into-addons-mozilla/37412. I will be closing the repository this week since I realize it's pointless to discuss modifications since I can't apply them.
