since the half-fix was back ported to ESR and thunderbird, assume that selectAllChildren() doesn't set the primary selection on *any* version of firefox anymore.

Disable the deceptive text highlighting in newer versions of firefox on X11, since selectAllChildren() no longer sets the primary selection. The breakage is caused by the half-fix for the exploitable pastejack bug[1] that I have reported.

Use css to still allow users to copy the code to the primary selection with a single click.

Add a more direct explanation on why saving the keys may fail.

add the extension button to the navigation bar by default
select and highlight the generated text on all non-touchscreen devices
set minimum version to 63.0: the first which supports navigator.clipboard
get rid of the invisible iframe target kludge

allow for keys not multiple of 40 bits; for instance, mozilla's bugzilla is using a 128 bit key (130 bits / 26 chars with no padding in base32)

revert to using a checkbox for the show password toggle

cut a bit on css-for-functionality abuse

use <ouput> for parts of the page which are dynamically modified (the code and errror)

Save an extra click on X11 by automatically copying to the primary selection upon generating the OTP.

Give some visual feedback on whether copying to the clipboard has succeeded or not.

Use a single file for both the popup and the tab page; use css to trim stuff out.

Various css tweaks

use an opaque icon (still not pretty, but at least visible in dark mode too)
in the popup: select the OTP code (and copy it to clipboard) when clicking on it
minor css fixes

simplify totp.js
also reset the input's validity when autocompleted
let the "show" text act as a label form the "show" checkbox
allow wrapping of text in buttons
other css fixes and tweaks

handle invalid input

separate generating an OTP from triggering the password manager

other minor fixes

disable the minlength attribute on the input for now
