Works amazing. Please do not add the watermark back as that is a deal breaker for OLED users.

Hotkeys don't always work in firefox. Whyyyyy is there a watermark? I'm uninstalling and searching for an alternative simply because of the dumb watermark.

Watermark in Firefox..

Big ups to this dev for listening to feedback

This was originally a 1-star review of a version that had a watermark added in the non-Pro version. After kindly listening to our feedback, the developer changed this, and I can now wholeheartedly recommend the add-on! Much appreciated.

5 stars now, thanks!


OG: Works great for cropping widescreen to 4:3. Although in 3.5.0 a watermark was added for free users, shame it used to be open-source too :/

Well done awesome..love it 👏

This fixed the problem where when I would try to watch anime on my websites this allowed me to force a true full screen aspect ratio thanks

Works great for the most part. Only problem I have is that it makes Plex fail to change the video (next/previous, changing a stream etc.) when in fullscreen mode.

AWESOME

i don't have an ultrawide monitor, but since every video now has some other aspect ratio than the regular 16:9 monitors, this extension is a must.

thank you and good job!

I had to downgrade to Version 3.3.4 because the Addon doesn't work on some sites it used to work with. Example 1: "heute.de" (reroutes to zdf.de) videos show a black screen, when viewed in fullscreen mode. Example 2: I sometimes watch videos via the Plex Web App and since the newest version the Addon doesn't seem to register the player anymore and stays in 16:9 in fullscreen mode.
Both sites work fine with the downgraded version.

EDIT: regarding Plex. I just tried it again, even deactivated all other firefox extensions except UltraWideo and when I use the Plex Webb App Player with Version 3.4.3 and load up a Movie or Series from my server, going fullscreen only shows the video in 16:9 with black bars on the side.
Doing the same thing with version 3.3.4 and it works as intended and stretches it horizontaly, so no more black bars. Not sure what else I can do to help in this regard.

It worked for me. Thanks.

a good portion of the video on the top and bottom is gone due to the zoom of this extension. It does go fullscreen but you lose video as a result.

If you don't mind that, it works! otherwise I'd like to see the whole video and it doesn't work well enough.

Perfectly Work on Jio hotstar.

ti amo, estensione migliore al mondo per monitor ultra wide

Works perfectly with my 4:3

Wonderful addon for those of us with a secondary or primary CRT monitor, since a lot of people forget to encode youtube uploads in 4:3 even if they contain no data outside that resolution.

My only request would be to allow it on a per-tab basis or restrict it to certain aspect ratios, since my primary monitor is ultrawide and I'd have to disable it manually every time I wanted to switch monitors. It looks like that's a work in progress for the pro version, but I'm not sure. Excellent addon nonetheless. It works instantly and flawlessly.
