>I do also suspect firefox does some hidden retries if it can before it considers the download to have failed
There is no such mechanism.
edflsafoiewq 1 days ago [-]
I'll try this.
The way I have to resume downloads in Firefox is
1. Move the .part file to a temp file
2. Start the download again; a new .part file gets created
3. Pause the download
4. Move the temp file to the .part file, overwriting it
5. Unpause the download; it resumes from where the old .part file stopped
This is only necessary if a "one-time" download link gets interrupted part-way through, eg. by a flaky connection. Attempting to resume a one-time link like normal gets (I assume) a 400 response and FF kills the .part file.

I used to use GetRight to download big files over FTP or HTTP, over dialup. You could set it up to automatically re-dial your ISP if you got disconnected halfway through a download. And you could download a file in multiple "threads" - for example, get 2 concurrent HTTP sessions downloading the same file, one thread starting from the start and a second thread starting halfway through the file.
GetRight did all this in 1997.

How would you solve it?
ruszki 15 hours ago [-]
This trick means that there is a check when you resume a download compared to when you start one. Introduce that check to when a download is started.
edflsafoiewq 15 hours ago [-]
The situation AFAICT is something like this: the server mints unique download URLs which can only be used once. This is generally so they can't be shared. It serves the URL to the first comer and when that connection drops (maybe with some timeout) subsequent requests to that URL produce 410 Gone. So if your download fails halfway through, you can't re-request the same URL with a Range, which is how normal resumption works. You need to get a new one-time URL minted and download that.
So from the browser's perspective, these are two distinct, unrelated URLs. There isn't a mechanism where it can know they are backed by the same file.
This browser behavior seems pretty reasonable. I'd try fixing it by doing something different on the server.

One caveat with that trick: if the server picked a different file or the link now points at a new version, Firefox will happily splice the old .part onto the new bytes and you get a corrupt file with no error. Resume requests only check the range, so unless the server returns an ETag or Last-Modified that matches, nothing guarantees the two halves belong together. Worth checking a hash afterwards if the source publishes one.

if the downloads were not idempotent, then yes, this method will simply splice two different files together. But presumably, most downloads are idempotent.

I like using the aria2[0] download utility - I don't think I've downloaded anything bigger than a dozen megabytes through a web browser for the last several years, and this method allows me more protocols, multiple connections, and of course continuing downloads. That said, it's nice someone found a solution to the problem - makes life easier for everyone who doesn't use an external download utility... How do you even go about finding the solutions to bugs like this?
I use aria2 sometimes, but one thing that surprised me is that it doesn't fully support retries. As in, even if you pass something like "--always-resume=true --continue=true", if you try to use aria2c on a bad connection, you will sometimes get errors which make aria2c just exit. Thankfully it does have good resume support, so I was able to wrap aria2c in a bash script that calls it repeatedly until the download succeeds, but it's strange to me that this was necessary.
Until you hit a large download that also requires cookies. We need this to be integrated with the browser.

Based on the setting `network.http.response.timeout`, which is timeout related, I'm *guessing* Firefox cannot distinguish between a network EOF or a logical/request-level EOF?
But that aside, it's kinda typical for a software from the developed world to have fault tolerance this bad. The engineer who wrote the code probably never ever annoyed by network error aside from a few well-known cases, and thus don't take these problems to their hearts.
For example, have you tried to download big files with a connection that has 100ms ~ 20seconds latency jitter? That happens with crossborder connections in/out of China. And in India, your users sometime experiences power issue which set their router to reboot or redial, that also causes an interruption in download.
Of course, people in these countries can't pay you much. But, these problems can all be solved/mitigated in software. Do you want to improve your software so it can be more robust, or do you want to waste user's time sitting in front your software just to get things done?

I think it's generally true that nobody really does good testing on machines that aren't top-of-spec and on internet connections that are at least 200MBps via a mesh network of some kind. There's an entire subaltern world of users who experience the worst of UI bloat and incessant network traffic of high-surveillance analytics capture tech (eg Fullstory, Microsoft Clarity) on very meager hardware with not-great internet connections.
Even in the Global North, rural internet is totally shit with no real fiber extensions out. Tech companies imagine a world where their users all uniformly have M5 Pros at minimum with 32GB of RAM (minimum - my last company gave us 128GB as default lol) and gigabit internet - it was always a joke when I would limit network activity and resource usage to emulate worse hardware when testing. That just gets in the way of deadlines and, plus, the poor can't pay for the service so why develop for them?

Stop using Deutsche Telekom and this problem will go away. They habitually avoid short routes because they are trying to extort all the recipients of traffic to pay thousands of euros per week for a direct connection. They only recently connected to Cloudflare, and they didn't publicize which side is paying, nor how much, but I hope it means DT is finally bleeding so many customers they're desperate.
Resumable downloads in firefox generally appear to be fairly unstable though. This has been a known problem in some form since as far back as 2005.
It's odd how the experience differs so much; I clearly remember successfully resuming a download less than a month ago, and I don't remember any time Firefox had any problems with them. My network.http.response.timeout is the default of 300.
There are reasons, but until someone actually publishes an article that's more detailed than the vagueness here, there's nothing anyone can really do about it.

Is there a "large download" we can use to test
It's troublesome that this blog author cannot look at the source code of the browser she's using:
"I have not attempted to confirm any of this with FF's source code, because I have no clue where to look."
I have the source code to the browser I use in a folder. Total folder size is 13.6M. The statically-compiled browser binary is 1.3M
I normally prefer tnftp for large downloads but this browser IME is also reliable for downloading files, no problems with resume (append), timeouts and number of retries can be adjusted. I mention this because there are comments in this thread that make sweeping generalisations about "browsers". Perhaps they only refer to large, popular ones

Of course, people in these countries can't pay you much. But, these problems can all be solved/mitigated in software. Do you want to improve your software so it can be more robust, or do you want to waste user's time sitting in front your software just to get things done?
Even in the Global North, rural internet is totally shit with no real fiber extensions out. Tech companies imagine a world where their users all uniformly have M5 Pros at minimum with 32GB of RAM (minimum - my last company gave us 128GB as default lol) and gigabit internet - it was always a joke when I would limit network activity and resource usage to emulate worse hardware when testing. That just gets in the way of deadlines and, plus, the poor can't pay for the service so why develop for them?
And sometimes in Germany. Let's not hail China again. /s
It's odd how the experience differs so much; I clearly remember successfully resuming a download less than a month ago, and I don't remember any time Firefox had any problems with them. My network.http.response.timeout is the default of 300.
There are reasons, but until someone actually publishes an article that's more detailed than the vagueness here, there's nothing anyone can really do about it.
You then let it start, then cancel, right click, copy download link, then use wget on the machine you want the file on.
(Back in the days before tcp window scaling, I tended to use axel)
It's troublesome that this blog author cannot look at the source code of the browser she's using:
"I have not attempted to confirm any of this with FF's source code, because I have no clue where to look."
I have the source code to the browser I use in a folder. Total folder size is 13.6M. The statically-compiled browser binary is 1.3M
I normally prefer tnftp for large downloads but this browser IME is also reliable for downloading files, no problems with resume (append), timeouts and number of retries can be adjusted. I mention this because there are comments in this thread that make sweeping generalisations about "browsers". Perhaps they only refer to large, popular ones
It's difficult if not impossible to examine an issue with Firefox without an example of a "large download" that purportedly it cannot resume

Install JDownloader 2. Just copy a link, and JDownloader will pick it up if it's running (otherwise, open it manually).
It not only downloads the file and lets you resume the download, but can also download multiple pieces in parallel.
Other people's code is a security risk.
Just point Claude to a project, and make it clone it, in a safe way.
Otherwise I haven't heard of Claude putting backdoors into small programs, or leaving critical vulnerabilities in them, after asking to reevaluate security and test it.
BTW. The "won't load new pages" may be something else. If an agent launches its own Firefox in a new profile, it will sometimes trigger the auto-update which will overwrite the binary in the profile you were using. It won't crash but you'll get a warning to restart.
It shouldn't even have access to the same binaries you are using but only those within the jail it is running in.
Don't. Just copy the URL and download it with curl instead.
Luckily the reliability of the internet has improved since then and it's less of a problem, until you encounter a bad connection or server.

Hey, asking where to look sounds like a great use-case for--

Ok
Reproducing the issue may be the best next action.
