became useless overnight, not very wise

Al intentar ver videos de youtube insertados en otras paginas no los carga ni deja visualizarlos se quedan en negro y tengo que limpiar la cache para que vuelvan a funcionar. esto me sucede desde la version 1.2.0.
hola comentar que con la version 1.2.4 se SOLUCIONO el problema. gracias por tu trabajo ya que para mi este addon es indispensable para ver youtube. saludos

Used to be good, now it isn't, removed all useful features.

DO NOT UPDATE.

Where can I download the old version?

Unnecessary to release an in-development version without anything useful over a working extension. Developers could have waited for the features to be rebuilt before releasing.

I used this addon for a while, and I loved it, but the most recent update removed almost every feature and broke embedded youtube videos on other sites. If the issues are fixed, I would love to come back, but right now it just is not in a working state.

EDIT: Thanks for the reply. I saw the link to some random reddit thread, but not that Github issue report. Refreshing with cache cleared (Ctrl+F5) with Iridium disabled/uninstalled immediately fixed the issue. Why reply to all of these users having this issue with these wordy responses when this is all you have to do?

Still, Iridium must have corrupted something in the site's cache, as no issue existed until I installed/enabled it for the first time in months (when I started using Enhancer instead). There's no way I'm going to blame the website for behavior that only occurs immediately after installing and uninstalling an extension, with no change in website coding, browser version, etc.

Updating review to 3 stars because of the feature evaporation (why not restore more functionality before releasing the code rewrite?). But for anyone else affected by this, try Ctrl+F5 for a full refresh while Iridium is uninstalled/disabled, and you should be good to go.

EDIT 2: Also, while trying to call me out for not using Reddit's search function (which is known to be garbage, by the way lol), you link to two threads, neither of which are referring to the issue I had. Guess you never looked at the screenshot I provided. If installing and uninstalling your addon immediately creates an issue that requires clearing the cache to fix, the addon is at fault. Obviously. Also, I didn't say this addon was malware, I said the behavior was on the same tier as that of malicious software (that is, 'things break if you remove it').

So yeah, was using Enhancer for YouTube for a long time with Iridium also installed, but disabled, since I liked Enhancer's feature set more, and figured running them both at the same time would cause conflicts.

Saw that Iridium had a bunch of updates recently, so I decided to try it out again. So I disabled Enhancer and enabled this. Saw many features were missing, so I swapped back. And the INSTANT I re-disabled Iridium, YouTube videos will NOT load at all, even if I restart Firefox in safe mode! Instead, the video area is completely empty, same color as the background, etc. Screenshot: https://i.imgur.com/al4WyRE.png ) The only way YouTube videos will load again is if I re-enable Iridium, and keep it re-enabled, even though it clashes with Enhancer when that's enabled too (e.g. videos will not autoplay with both extensions active, no matter what options I set). This all happened today, no Firefox updating occurred in between, nothing. YouTube broke as soon as Iridium was disabled. In fact, now, YouTube will never work while in safe mode, which obviously wasn't the case before. Uninstalling it completely gives the same result as disabling.

I see you reacting to other reviewers saying that there's no way disabling Iridium broke anything, that having it installed was taking care of some bug in the browser (and that reddit link does not at all describe the issue, which is that videos don't load AT ALL, it's not some FPS issue). But this is definitely the culprit. I don't know HOW uninstalling an extension managed to break the website it interacts with, but it did, 100%. Find out why, and fix it. Reporting the addon for abuse in the meantime, this is malware-tier behavior.

I can't believe new updates remove old features, this is ridiculous. I can't even install old versions of this addon because firefox figures them out as too old and automatically uninstall them.

I'm glad this is moving to Firefox-only for the developer to be able to work on it easily. Firefox is easily the best browser right now, considering Google's obstinacy surrounding public-standards-compliant API implementation in their flagship browser.

This extension has been essential for using YouTube, especially for allowing me to control volume with the mouse wheel, like any normal video player. I hope that feature is next on Particle's list to reimplement in the new refactored version. They are doing a great service to the community by continuing to develop this awesome browser extension.

Hate to shit on your doorstep but this update sucks, you literally removed everything and forced me on the new layout, Don't add a half finished alpha and not let us go back to the old version, you've neutered this whole addon and left us with some scraps of its former self, I loved it but now I can't even uninstall it because it completely breaks YouTube.

EDIT: A swift reply from the developer has completely resolved all the issues stated before, I wasn't aware you could downgrade, You can do so at https://addons.mozilla.org/firefox/addon/particle-iridium/versions/ I hope that with time the addon can return to its former glory but as of now I'll be using the older version. Best of luck to the developer, hopefully the addon can become even better!

WTF This extension, I removed it, and when I want to watch a video, simply no longer opens the page of the video, extension broke my browser, other YT accounts works normally, but the account I used not.

I've loved using the extension, but the newest update have so few features that I've rolled back to v0.2.5 for now.
I understand that you started from scratch to make it easier for you in the future, but maybe you should've waited to push the new version, until it had reached feature parity with the old version.

the last update broked everything, this add-on was perfect, reverse the update and my 5 stars are also back
-update, this developer is making this add-on as a hobby and he doesn't have a lot of time, please respect his work, he will release all the old features in the future
please check this : https://github.com/ParticleCore/Iridium/issues/737#issuecomment-541321036
edit 2: I installed and old version from this add-on and it's working perfectly ! just go to https://addons.mozilla.org/firefox/addon/particle-iridium/versions
And please Particle, open an Utip so we can donate by just watching ads of our own free will

Not working for me anymore. There's no iridium icon on youtube to access settings or anything. All the functions from before are missing. And most importantly, after uninstalling extension, youtube is not loading properly. Weird.

I was ok when it got "an overhaul" and didn't notify me, breaking youtube across all my computers.

I was ok when the "overhaul" didn't really have the core functionality, it was a half-baked alpha with empty menus.

I am NOT ok with the "overhaul" suddenly asking for weird permissions. Firefox should not be recommending this add-on.

(And no, I will not allow access to all my tabs, just so the extension doesn't show two option pages)

This was and eventually will be an amazing extension. Thanks to the author for putting a lot of effort into it and for sticking with Firefox <3

If you're not satisfied with the lack of some functionality in the newest version (which will be there at some point), just revert it back to 0.2.5 and be happy https://addons.mozilla.org/en-US/firefox/addon/particle-iridium/versions/ Stop leaving one stars which you will never bother to remove.

Does not work anymore since some updates already, I uninstall, it is useless to me

What a shame. Was a great extension, my favorite of all YouTube extensions, then the developer did a rewrite update which removed literally everything. Here's a tip: Don't push the rewrite update 'until' you add back all (or at least most of) the features that were originally there. Now it's the equivalent of a digital paperweight. At this point, I have no choice but to remove it and move onto something else.

What's the point of releasing something that works halfa$$ (it's not even half, more like 1/10 of an a$$). Completely ruined plugin.
