  • local history for easy "undo"
  • active development!

Pro features:
  • Live dials - turn dial into live small page
  • split single dial into multiple smaller dials
  • add multiple search engines into single dial
  • adding all opened tabs to your dials
  • Archive - hide your unused groups into archive

Sometimes the page is just not designed well and the information you are looking for is not visible enough.

Common use-cases:
  • highlight metadata like: 1080p, HDR, UHD
  • hide words (font-size: 0) you can't stand anymore (covid-19? :D)
  • make that "download" link bigger

Movie Meter

Download for:

Movie Meter shows you movie rating and it's popularity on many movie-related pages. For TV Shows it finds information about Next / Previous episode.

It will work on most popular movie streaming sites like Netflix, Amazon, YouTube Movies,, MoviesAnywhere, but also on Wikipedia, Fandango and many others.

If it doesn't work on your favorite movie page, let me know and I will add support for it.

  • movie rating and popularity
  • next / previous episode date
  • additional movie information
  • auto-hide when video detected
  • active development!
  • No Ads!

Note: since there is no "official" integration with target pages, I cannot guarantee 100% correct results. That said, in general it works perfectly.

Send Note to Device

Download for:

Send Note to Device allows you to send text messages (notes) between your browsers.

  • Send link with message! - do you use "Send Tab to Device" feature? This is similar, but you can include a note with the link!

  • No need to create additional account - Firefox Sync will handle everything
  • Inbox - history of last 100 received notes

  • No Ads!

New Window Setup

Download for:

New Window Setup is a small but super helpful addon for all multi-monitor users!

  • Firefox creates new window on the same monitor where the last focused window is. If you use multiple monitors and you have Firefox windows opened on each one, new window can be created on any of them. Using this addon you can force it to a specific monitor.
  • Firefox creates new windows with the same dimension as the last focused window. If your last focused window is snapped on a side, your new window will have this crazy dimension.

Using this addon, new window will be always created with correct size and on correct place!


Download for:

Darko will make your Thunderbird messages dark.

Link in Tab

Download for:

Link in Tab changes how links are opened in your Thunderbird messages:

  • Left click - open link in new tab

  • Middle click - open link in browser and close current tab (if message was opened in a tab)

Save my Password

Download for:

Save my Password will allow you to force Firefox to store your password on any page.

Why? Some login pages are designed in a way that your credentials are not stored by Firefox and you have to type them yourself every time.
