UltraWideo 제작자: nonwip

4.5 / 5

SirPoopsAlot 님의 리뷰

My Oneplus 6T developed a problem after getting an update. If I'm not using YouTube then all videos are cropped in to take up the whole screen, chopping off content. This happened for whatever browser I was using, including Chrome. Getting Firefox and this add-on solved that. I guess the only thing I could ask for is being able to pinch or unpinch to change the modes (normal/upscale/stretch) or something like that. That way I don't have to open the menu to change it if I ever want to.

Edit: for those of you unable to use this, check out F-Droid and Fennec. F-Droid is an open source Android repository (think of it as a 3rd party app store for free/open source apps. Fennec is a free and open-source version of Firefox, and using Fennec you can download the specific older version of Firefox(Fennec) that allowed non recommended add-ons like this. I believe it was version 68.12.0

Thank you for the review. Please explain what is F-Droid and Fennec to those Android newbies or to non-android users that might want to switch and try.

I am personally not familiar with it and I find it unfortunate that Mozilla doesn't want to select this add-on as "Recommended", so that everyone can install it on their Android devices.

I've been using it for a long time - it always works great!
I haven't had any problems with this extension, and I hope I won't.👍

Hello,

Last update was: 3 months ago (Jan 4, 2026)

So nothing was changed "recently". It's either something related to Linux or an extension that you have installed that is conflicting with UltraWideo. If you have any extensions that have similar purpose, uninstall them.

Also, have you tried uninstalling entirely and installing again? If you did, and it still does not work, I am happy to check it out over AnyDesk or something that you have on Linux.

I have no clues otherwise why it would stop working for some users. I've been getting straight 1 star reviews with no helpful feedback on GitHub that would help me to debug and resolve the issue.

Aside, working fine for me in Firefox 148 on macOS.

Any help is appreciated!

Best,
Nenad Novakovic.

EDIT:
Thanks for editing your review. Don't harm yourself with such words, over it.
I would appreciate to hear what was the issue that you encountered, as it may be the same reason why two/three users below gave me one star.

Перестало работать, на любом из сайтов... (p.s. версия 3.5.4 работает отлично, версия 3.5.5 не работает

This isn't helpful at all. Mind telling me how 3.5.5 isn't working? There's literally only change for the scaling option that makes scaling of X or Y axis - reflect the change of the other that's modified.

Tested in latest firefox and in nightly and it seems to work fine for me still.

Works better for me than the other one, Ultrawidify. Also, the UI is nicer. Only annoyance so far for me is that I can't support it/purchase Premium with just a one-time purchase. I would if that was an option.

Just after a couple days using the video doesn't show correctly. Only half the screen. It cuts off the bottom half

Works well on most pages but recently subtitles stopped working on fullscreen mode on some of them, notably Disney+

It works decently well, but important features are locked behind a paid subscription that somehow requires a github account. I'm usually happy to donate if an extension is useful, but to not even be able to use it outside of fullscreen if I don't? And I didn't see a way to try the paid features and verify they actually work before paying, maybe I missed it.

Hello,

Pro features are indeed locked and there is no trial. The approach is, subscribe to keep extension alive and you will get those finished pro features unlocked as a bonus.

So adding them as "try before you buy - does not make sense in this scenario", sorry.
I do not think that any Pro features are really that much important, all the basic functionality is already there and free to use.

Thanks!

Asks for monthly payment and steals personal info

1. Not really. It's freemium, so payment is not mandatory.
2. No, where did you get that misinformation from? It collects zero data.

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.

If they don't work, it's firefox issue. Because extension is using browser's shortcuts API.
Watermark will disappear in 3.5.1, but Mozilla is slow on approval. Should happen this week I guess. Try Chrome?

Thank you for your input. I did not expect this tiny watermark to be huge annoyance, but seeing many negative feedback the watermark is removed in version 3.5.1.

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 :/
