Chrome: published as beta.

Firefox: published as 2.3.18, but because of bugs discovered in Android Firefox, this version was rolled back in AMO to 2.3.17 re-published as 2.3.19, so if you want to test it either use the link above or click the attached xpi file, also disable auto-update of extensions in browser preferences on desktop or in about:config -> extensions.update.enabled on Android.

Known bugs:

• #2037: Patch CSP option is broken.
• #2039: [Firefox Android] config and menu buttons in the popup aren't working

• Required minimum is Chromium 86, Firefox 68.
  Targeting older versions of Chromium seems to be no longer relevant since Supermium and other forks of reasonably recent versions of Chromium offer Windows XP support. Increasing the minimum allows us to remove the dead weight of nontrivial workarounds for bugs in older versions of the browsers (workarounds that no one have been testing anymore for several years) and use various additions to the JS and CSS platforms that we didn't use previously as polyfills would be either slow or inordinately big.

• Favicons in installer and editor:
  

• Allow deleting extra styles after import so you can effectively replace the entire database:
  
  
  

• New option: [x] Open popup in a side panel.

• New options for popup actions to open in a side panel: Style editor, Style manager, Options, Search, UserCSS config.

• New options to set custom sites for advanced options: Instant inject, Patch CSP, Expose iframes, Circumvent CSP via ASS

• Allow /regexp/ syntax in personal included/excluded sites in the editor and in the advanced site-restricted options.

• [Popup] Menu to force-include/exclude style for the current tab or domain/url/prefix:
  
  Hold Enter or Apps key and press a digit to open the menu.
• [Popup] Hold Alt to toggle styles only for the current tab.
• [Popup] Right-click or long-press on an action button to force-open in a side panel.
• [Popup] highlight force-applied styles

• [Editor] New option: [x] override style in Style settings -> Personal included sites, so your list overrides the intrinsic sites of the style.
• [Editor] Fix double-click to select unicode tokens.
• [Editor] Colorize more modern color functions.
• [Editor] Prevent browser from hanging on long lines.
• [Editor] Improve autocomplete.
• [Editor] The option [x] as UserCSS is moved to the editor page from the manager/popup. Toggling the option in a newly created style before you modify it switches the style's format as well.
• stylelint 16.25.0, csslint-mod 1.0.5, less 4.4.2

• New hotkey and a context menu: Toggle current tab, the hotkey is customizable in chrome://extensions/shortcuts in Chrome or in about:addons in Firefox.
• fix Opera detection + show search page option hint.
• fix installation on userstyles.org.
• increase some paddings on touch device.
• show uncaught Stylus errors so you can report them to us, click the text to copy it to clipboard and remove it from the screen.

It's the only UI-facing difference so far between the attached firefox-mv2 build that is optimized for Firefox (previously we only submitted it to AMO, now it's added to releases and nightly builds) and a generic/universal mv2 build. There should be no detectable difference in performance.
