Hello! Just installed Ubuntu 20.04.4 on my laptop and now find that I'm not able to watch some YouTube videos on Firefox 97. It seems mainly just live streams that I can't watch. When I go to one it shows "Your browser can't play this video...Learn more" in the video window. Clicking Learn More takes me to a page that doesn't explain what the problem is. Any idea what the fix might be? The same videos play just fine on other devices on my network. Any help would be greatly appreciated.

Dear volunteers,

I am on Debian 11, Firefox 98.0.1.

Firefox reader mode only seems to render half the article I am currently on, example:

https://www.newyorker.com/news/q-and-a/the-purges-in-putins-shrinking-inner-circle

The reader view only renders up to "I think it’s a big challenge for them." but the actual article continues.

Is this a bug on my setup?

Thank you for taking the time to read this!

Hi,

I use Mendeley Web Extension to pull articles and other things from Firefox directly into my Mendeley library. I will usually rapidly read through the PDF file online before deciding to add it or not. For some unknown reason, Firefox blocks the use of Mendeley on PDF file, for security reasons, and I can no longer add them to my library. Most references are only available as PDF files making the add-on completely useless. Is there a security feature that I can disable to be able to use the extension again?

Kind regards,

Mathias

I was messing around with Privacy & Security settings. Under Cookies & Site Data, I checked Delete Cookies & Site Data when Firefox closes. I've decided I don't like it and want to uncheck it. But now it's greyed out and I can't find any way to change it back. It says I'm in permanent private browsing mode. There MUST be a way to change this back to how it was! What is it???

I can't open a Spotify URI from Firefox But I can open it from command line using the --uri option. As in, this works fine from the terminal:

spotify --uri="spotify:artist:6OqhFYFJDnBBHas02HopPT"

and whatever Firefox is doing just launches Spotify without navigating to the thing indicated by the URI

Is there, perchance, a simple file edit I can do that will fix this for me?

So the problem is that Firefox doesn't play any HTML5 content. Weirdly except for Youtube. Youtube works just fine. But every other Website shows errors. Even songsterr.com. I'm using latest Firefox 76.0.1 on a recent Ubuntu 20. 04 LTS installation. Usual troubleshooting like updates doesnt work because "sudo apt-get upgrade" doesn't find any updates. I tried the same websites in the latest version of Chromium and they work perfectly fine. I couldn't find a mistake in the firefox settings or something so I'm confused. Disabling Plugins didn't change anything and turning of tracking protection didn't either. What is the Problem here and how can I solve it?

I am unable to connect to the following URL https://lakmshaegov01.msha.gov/UserManagement/ChangePassword.aspx. All other browsers seem to work.

I ran an SSL Labs test and it confirms that all tested versions of Firefox fail. I would like to know if anyone can spot something that might allow me to connect by temporarily relaxing the security checks in Firefox for this site.

Hello SUMO Team!

  I always had this question but never really asked it. Why isn't DuckDuckGo or a more privacy based Search engine set as default? You even have to manually add Startpage and others... 

 It just hurts me how a privacy browser has the Google search engine as default after all, most people come to Firefox for privacy and Google is the opposite. Maybe one of the developers can change that?

Thank you so much for trying to help me and Stay Safe!

How do I disable the blue flash when a tab finishes loading? I'd like to suggest an option in a future release that disables all these things.

I find it a real distraction, and it's really putting me off using firefox as a broswer. I really don't think this sort of eye candy is needed in order to browse the internet.

I'm using OpenSuSE Leap 15.2 , updated Firefox these days, and now when I click on the menu, it opens and shows up to the right, out of the screen (when maximized). Also when I hover over options close to the right edge of the screen, the bubbles show partly out of the screen, same as the main menu. I've tried Refresh, Safe Mode, downgrading to a previous version, but nothing helps now Mind the menu on the screenshot.

Any ideas?

best, Istvan

I am building a website and, for the last couple of days, when I make changes to the CSS file they are no longer being picked up by the browser by which I mean they aren't displayed in the web page nor in the developer tools inspector.

They are visible in Chromium browser and dev tools.

I have cleared the cache and refreshed the page to no avail. It is only when I restart the browser that the new style rules take effect in the browser and show up in the dev tools.

Here is a Jsfiddle URL URL which points to Twitter Tweet Button JS / HTML code which I am attempting to embed into a website.


When I load the above in Google Chrome 84 the Tweet Button appears and I can share out the URL of the web page in which the Tweet button is embedded, with no unexpected results.

When I try to do the same with Mozilla Firefox 79.0, in Private Mode, and disabling uBlock extension, the Tweet button does NOT appear, only the "Tweet" text. When I click on the Tweet text, I can not share out the URL as expected.

I am wondering what specifically in Mozilla Firefox could be introducing the problem.

hello, i have a Raspberry Pi 4 with 4GB and Raspberry Pi OS installed. (2020-05-27-raspios-buster-armhf.zip)

when i use the stock Firefox ESR (installed via sudo apt install firefox-esr) and watch videos (e.g. on Youtube, Vimeo, ...), Firefox does crash some times. according about:crashes, i already have submitted about 60 crash reports.

but watching the reports one thing is missing. when i open firefox from the console i can see some output, that is not appearing in the reports.

... firefox-esr: /build/firefox-esr-RgOFaD/firefox-esr-68.11.0esr/media/libcubeb/src/cubeb_alsa.c:1255: alsa_stream_get_position: Assertion `delay >= 0' failed. ExceptionHandler::GenerateDump cloned child 3366 ExceptionHandler::SendContinueSignalToChild sent continue signal to child ExceptionHandler::WaitForContinueSignal waiting for continue signal... Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Failed to open curl lib from binary, use libcurl.so instead Firefox ESR crashes when playing videos on Raspberry Pi OS (Debian)

during watching videos in firefox there is more different output to see that seems to be harmless. but always and only this line is printed to console, just befor Firefox crashes: firefox-esr: /build/firefox-esr-RgOFaD/firefox-esr-68.11.0esr/media/libcubeb/src/cubeb_alsa.c:1255: alsa_stream_get_position: Assertion `delay >= 0' failed. so i assume this is the main reason, why Firefox crashes on my system.

any idea how i can get these issue fixed? at the moment when i want to watch videos reliable i am be forces to use the external VLC Player by copy the url to VLC - at least for Youtube videos. but i want to watch videos from other web pages as well and i prefer to watch videos in firefox directly.
