The issue with reddit and other sites should be fixed. It's not a proper fix, I've just set extension to not work on any site other than youtube or netflix and sites that you explicitly enabled via the extension button/popup.

I've also kinda solved the problem with the memory leak: extension will only check for changes in aspect ratio once per second if the video is playing. This massively reduces RAM usage back to acceptable/negligible levels.

On that note: I've also added an option for you to change how often the extension checks for changes in aspect ratio, but turning that number back to 30 (what it used to be) is not recommended because RAM usage will skyrocket for technical reasons (tl;dr of which is pretty much "blame javascript").

Netflix is actually broken right now (according to multiple reports), but unfortunately I haven't been able to get access to netflix yet.

I'm working on a fix (along with some other changes), though — but the buttons aren't making a comeback. Only the keyboard shortcuts will stay.

Please make bug reports on Github, as it makes it easier for me to track them.

Regarding netflix: thanks for mentioning it. Unfortunately, I won't be able to fix netflix until at least two months from now due to financial issues.

Regarding autodetection: It was specifically stated it only works on Netflix. Are you sure you sure your Netflix is in English (and that the movie is in English/original title)? Are you sure that the movie is on iMDB _and_ OMDB?

Given that I'm finally freed of my real-life commitments that took most of my time for the past six months, I'm slowly starting working on this extension again, which makes me rather interested in the details of any reported bug.

Bug reports this way please ---> https://github.com/xternal7/ultrawidify/issues

Take care to include browser version, OS, monitor resolution, other extensions.

Potentially also screenshots because I don't know what the hell you mean with 'doesn't crop properly'. "Fit to width" should crop perfectly if you're watching 21:9 content encoded in non-21:9 aspect ratio on a 21:9 monitor.

And if you have a monitor with aspect ratio wider than 21:9 (this one Samsung), you should use 'Force aspect ratio' option for proper letterbox removal.

(Also please note I'm currently on hiatus due to some personal issues. If all goes well, I'll be able to continue with October)


========
EDIT: I think I might have randomly stumbled over the "doesn't crop properly" instance. There's this trailer for Salt that's 16:9 + letterbox, but the video isn't 21:9. This leads to extension cropping away too much:

Which is why there's zoom/unzoom binds.

Automatic aspect ratio was impossible(-ish)¹ a year ago. It's still impossible-ish¹ now.

¹It's actually within the realm of theoretical possibility, but whether that's gonna work with Youtube is unclear until I test it. There's also further potential complication with attempting auto-aspect ratio on youtube, vaguely outlined under this review:

TL;DR: potential performance issues.

Inb4 "but it can be done on netflix" — Netflix aspect ratio "autodetection" isn't true autodetection and is only possible because IMDB generally posts aspect ratio of every movie it knows.
