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.

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.

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!

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

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.
