Musescore Download Chrome Extension
Aleck Cobbs
hi,
i would like it if you made an extension for google chrome so i can use musescore on my chromebook (chromebook runs off of ChromeOS and doesn't support exe or other file types like that and you can only download apps from the chrome web store)
Chrome OS and the Chrome extension framework don't provide nearly the functions they would need to in order to support MuseScore directly. Luckily, it doesn't need to. There are currently two options for running MuseScore on a Chromebook without the need for a Chome extension, and a third will hopefully be coming soon.
One is to use "crouton" to install Linux as mentioned above. This works great but is a lot of work. Another is to to use a third-party service like "rollApp" to run MuseScore via a remote access service. The third option that will hopefully be available soon is to run the Linux version of MuseScore on the Chromebook. Google just announced that this capability will be coming soon, but it's too early to say how practical it will be.
just think of the possibilities of a browser version of musescore... compose anywhere on almost any device, full playback and soundfonts (from an online bank), truly collaborative composition (as in Google sheets, but for music), cloud storage, etc... If i had a composition idea, but my composition computer was not with me, I could go to a kiosk somewhere, or use a phone or other browsing device and quick enter my idea for retrieval and completion another time.
@jmoses this is about MuseScore running on Chrome OS, not running in the Chrome browser. That said, what you want is possible on any Windows machine using the portable version of MuseScore on a USB key. Just plug in the key and start MuseScore.
But FWIW, you can already do most of this - that's what the "rollApp" service I mentioned does. There are some limitations currently, most significantly lack of audio support, but they are working on it. No collaboration facility, that would be nice someday, but so would winning the lottery :-)
After you download the crx file for Musescore Downloader 0.4.1, open Chrome's extensions page (chrome://extensions/ or find by Chrome menu icon > More tools > Extensions), and then drag-and-drop the *.crx file to the extensions page to install it.
I can no longer successfully click on online links to open certain file types that I use. All I get is a page of garbage in Firefox. I can't delete the types because they are not there, but clicking on them does not ask me what action I want - just opens the garbage page.Filetypes happen to be .mscz (musescore) and.ove (overture) and I had working associations until the latest update.
Thank you Alice. I've now remembered that 123-reg has moved things to a different server (or something): so that explains why things that used to work did so no longer. Anyway, problem solved - took some time as I had to experiment with exactly what went in the content field, but I've got mscz, ove, mxl and other links all(?) working now.
When you right-click on a .mscz (musescore) or .ove (overture) file, save it to your computer and then double-click it in Windows, what happens? Do you have an installed application that can open mscz (musescore) or .ove (overture) files? If you do and online links don't open, it could be a problem with the website that includes links to those types of files. Do you have a link to some problem online files?
In any case, see Manage file types and download actions in Firefox. As a last resort you can reset download actions for all content types by renaming the handlers.json file in the Firefox profile folder, as explained here.
This can also happen if the server isn't configured properly and is sending the file as content-type: text/plain instead of a valid content-type for this file extension.You can possibly check that in the Network Monitor.
I'd already tried renaming handlers.json but it didn't work: Firefox just created an identical one (with very little in it - I'd recently done a "refresh Firefox" which may or may not have compounded my problem).
If I right-click the link and select "save link as" it saves the file in Downloads, and if I double-click that it comes up correctly in the application (PDF, DOC, MuseScore, etc). Musescore is on my PC and has been for some years - up to now clicking on the link in the webpage has worked, and still works in other browsers.
Further test.I have created a web page on which are 6 test files.- 4 have regular known extensions (doc, odt, pdf, txt); all these do as expected when clicked on.- 1 has a specialist extension mscz; this should open musescore on my PC, but instead treats the file as text and puts garbage on the page on the screen- 1 has a nonsense extension zij . This file contains some lines of text. When clicked, FireFox opens it as text.
As zij is a "new application", my understanding is that FireFox should ask me what I'd like to happen (e.g. save or nominate an app). It doesn't. Furthermore, there is no way via the change-what-firefox-does route in which a new application can be added. So I think it's a fault with the latest upgrade.
The problem appears to be a misconfigured web server, as cor-el suspected, which does not include the correct content-type (MIME-type) for and other files that display as text/plain ("garbage") In Firefox. Mozilla browsers need the correct content-type to properly handle the file, for security reasons. Other browsers may try to guess the content type. To learn more, see: -US/docs/Learn/Server-side/Configuring_server_MIME_types ... EDIT: See also _sniffing
I installed -US/firefox/addon/content-type-fixer/ as cor-el suggested, turned it on via the toolbar icon, downloaded (which displayed as plain text) and then viewed the log from the Content Type Fixer toolbar menu. Log of Recent Requests showed this:
The people who answer questions here, for the most part, are other Firefox users volunteering their time (like me), not Mozilla employees or Firefox developers. If you want to leave feedback for Firefox developers, you can go to the Firefox Help menu and select Submit Feedback... or use this link.
You can also file a Firefox "File Handling" bug report, if you wish. You can check this list of open bugs and this list of resolved Firefox File Handling bugs, to see what bug reports already on file.
Yep. I knew after I'd sent the message that I should have thanked the others also: I'm getting careless. I'll try the developers route if and when time permits (time? I'm retired and should have lots of it - but it doesn't quite work like that). I suppose it's sad that after 57 years of working with computers in one form or another I find it difficult to navigate today's maze, but I doubt if I'm alone in that.
I just wanted to add that, when I wrote before that other browsers may try to guess the content type, I meant OTHER browsers, not Mozilla Firefox. I based this on -US/docs/Learn/Server-side/Configuring_server_MIME_types which says:(quote)Some other web browsers, such as Microsoft Internet Explorer, try to allow for misconfigured web servers and applications by guessing what the correct MIME type should be.
However, that article was written years ago and may not apply to current versions of other browsers. Since you do have an application that can handle mscz, ove, mxl and other links, you can test problem links on using Microsoft Edge, Internet Explorer, and Google Chrome (if installed) to see how those browsers handle file extensions involving misconfigured web servers. If the links open in the right program, it means those browsers are "guessing" what the correct content type should be (see _sniffing for how this is done).
Another addition: other browser can use the file extension and check the Windows Registry to see if there is an application installed that can handle this file extension.Firefox always use the content type send by the server in case the server sends a content type. If no content type is send then Firefox can check the registry and offer a possible application. If the server sends a text/plain content type then Firefox will open the file in a tab and I would expect other browser to behave the same.
Registry Location is mentioned in the Microsoft Doc MIME Type Detection in Windows Internet Explorer. I didn't know that a web server could send a file with "no content type"',in which case[*] "Firefox can check the registry and offer a possible application.". Do you have a reference?
It's important to note that the application itself and the sheet music to which it provides access are not the same thing, and they are not provided under the same license. The application itself is GPLv3, but the musical works it enables access to via musescore.com have a wide variety of licenses, including public domain, Creative Commons, and fully commercial.
Muse Group's beef with Xmader comes from two other repositories, created specifically to bypass subscription fees. Those repositories are musescore-downloader (created November 2019) and musescore-dataset (created March 2020).
Musescore-downloader describes itself succinctly: "download sheet music from musescore.com for free, no login or MuseScore Pro required." Musescore-dataset is nearly as straightforward: it declares itself "the unofficial dataset of all music sheets and users on musescore.com." In simpler terms: musescore-downloader lets you download things from musescore.com that you shouldn't be able to; musescore-dataset is those files themselves, already downloaded.
Just because you can access the score via the app or website doesn't mean you're free to access it anywhere, anyhow, or redistribute that score yourself. The distribution agreement between Muse Group and the rightsholder allows legitimate downloads, but only when using the site or app as intended. Those agreements do not give users carte blanche to bypass controls imposed on those downloads.
