Firefox Community Forum

After a recent update, I noticed that my toolbar changed suddenly. I was able to rebuild it how I like and most of it stays, however, the "Open A New Tab" button refuses to stay where I want it.

Whenever I open a new window of Firefox, the "Open A New Tab" button is found on the leftmost side of my screen beside the new tabs. If I go to the "Customize Toolbar" page, I am able to move it so it stays to the right of the rightmost tab, which is where I want it to be.

Anytime I open a new window, whether it's through dragging a tab onto another monitor, or opening Firefox the first time after turning on my computer, my change gets reversed.

How can I permanently move this button to the desired position?

This did not become an issue until an update about a week or so ago.

using Firefox Developer Edition Version 130.0b5 (64-bit)

https-only mode is enabled for all windows enabled, with a couple exceptions. one of those exceptions is www.bom.gov.au , which does not support that mode. anytime someone tries to open a page from there in said mode, leads to a page that redirects to it's homepage, highlighting that it is unsupported, and changing from any specific url to the redirect url.

in the past it worked well to have this page listed under the exceptions for https-only, always loaded without a hitch. but now it's treating the page as not an exception. i've removed it from the exception list and tried loading, re-added and tried loading, but the result is always the same. can anyone please help?
