I am using Ubuntu 20.04.1 LTS. I have installed the latest version of Firefox. However, Firefox does not play Vimeo videos. The video's title frame downloads and the loading button displays but the video never starts. Interestingly, the video plays very well in Chrome.

I have already done what is recommended in the following webpages: https://linuxize.com/post/how-to-install-ffmpeg-on-ubuntu-18-04/ https://vimeo.zendesk.com/hc/en-us/articles/115015677227-Troubleshoot-player-error-messages https://support.mozilla.org/en-US/questions/1206076

But none of these solutions have worked. Could someone help me on this? I prefer using Firefox to Chrome.

Hi all. Mozilla Firefox is very slow on my Linux Laptop with the Qualcomm Atheros QCA9565/AR9565 Wireless Network Adapter (with open-source driver ath9k). It takes a lot of time to resolve hosts and to load the webpages.

I am reporting the issue here because Chromium and the rest of web explorers work good and they are as fast as one may expect. When using Windows 10 with the same laptop, Firefox also has no issues and works perfectly well. It appears to be an issue of the combination of Firefox + this specific driver & network adapter.

Used Manjaro, Ubuntu 16, Ubuntu 20 with a lot of kernels ranging from 4.15 to 5.8 and the issue persists and does not seem to be tied to any specific distribution.

I can do some tests if you require so.

You can see in the picture that it gets cut off.

Here's the pdf of the picture: https://mega.nz/file/6wwBUIaC#swNET5o7oGArqOuhxLqGhsPKElxznIe2aqvI0TFKO5E

If you see weird overlapping text, then just reload the page. idk why firefox sometimes doesnt finish loading the page…

As an aside: How do I keep the local links (that are in the webpage) in the PDF that Firefox generates?

PayPal pops up a window, which I want to dock as a tab in the main Firefox window.

How do I do that? The "natural" way was to grab the popped-up window and drag it onto the hamburger menu. A quick search only revealed a preference setting to force pop-ups to be tabs, but that is before-the-fact, whereas I would like an after-the-fact solution.

Thanks in advance.

I want to use a local html file as my new tab page. Currently there is no easy way to do this as far as I can tell.

Firefox at some point has removed the in-built option to set the new tab as a local file. Setting the home page as a local file is possible. But setting the new tab as either home (note, not 'Firefox Home') or explicitly the local file is not an option (see attached image).

Previous forum posts point toward New Tab Override extension. However, in recent releases, add-ons cannot offer a work around as Firefox no longer allows add-ons to access local files. In the image attached, New Tab Override extension shows that it cannot use a local file as the new tab. It can however take a file and store it somewhere it has control over. This means every time I edit the local file, I need to manually re-upload this to the extension in each instance of Firefox. It is no longer a good option.

I am sure I used this feature not too long ago and it feels like a very simple thing. I am sure I must have missed some setting or option. Any help achieving this would be greatly appreciated.

Hey There,

whenever the window is inactive and i want to scroll the site (with a touchpad swipe) it instead navigates forward or backward. ONLY when the window is inactive. the behavior is the same with horizontal and vertical swipes. I've tried disabling the feature like described here (https://support.mozilla.org/en-US/questions/915174) but i had no luck with that.

i'm using firefox 78.2. on an opensuse 15 laptop. thought i might be an issue with that but with chromium i dont have that issue

Please note that my question is not about preserving preferences. I've searched and found many Q&A threads on preference preservation, but I don't think that is my problem or issue.

What I'd like to do is to make some Ubuntu desktop menu shortcuts to launch specific web-based apps, in individual windows (I suppose separate instances and new-window) of specific size, with a given specific URL, hopefully with it's own icon, sort-of replacement of desktop apps. So in the Desktop menu I should be able to see 'Google Meet' (for instance) as an application with it's own icon, but clicking it launches Firefox with Google Meet's URL, and a window that is just 800x600 in size.

However, when I try to launch windows on Ubuntu MATE (also tried Lubuntu, and standard Ubuntu... all 20.04), firefox seems to ignore --window-size command line parameter, and all new windows are of exactly same size, which is the default size apparently, ignoring the command-line parameter. What gives ? How can I do what I am trying to as explained above (from firefox standpoint... I know how to create Ubuntu .desktop file etc.).

cheers, B

Greetings - I am using Firefox on Ubuntu 20.04.1. When I try to log on to a secured DoD site, I get the certificate selection pop-up. Normally, only two of three certificates are displayed.

How do I edit that window to display all certificates on the CAC card? Thank you for your time.

I'm seeing breakthrough of the background when Firefox is open on my second monitor.

This seems to occur when the window on the secondary monitor is minimised, then maximised and mouse over the image on the secondary monitor (second is right hand side) - see image.

Initially I thought this was a graphics issue but this does not occur when I repeat the steps with other applications. I have also tried it with Chrome and Chrome does not display the same behaviour. I do not see this behaviour on the primary monitor.

I have reduced the refresh rate from 144Hz to 60Hz and reset Firefox which has not cured the issue. It appears to me that the only application that exhibits this behaviour on this machine is Firefox.

I also started to see this occur on my previous machine which was based on Mint 17 and a different Nvidia GPU and monitors and had been stable for many years.

If there is any further information I can provide, please let me know as I'm loathed to change from Firefox as I've been a fan for many years.

Sometimes when I click a link (in an email) to download a document, a completely unnecessary blank tab opens immediately before the save dialog. A new blank tab opens for each document I download. There used to be a preference to stop that happening. The closest I can find is dom.targetBlankNoOpener.enabled but I can't find any intelligible information about that.

I decided to use Firefox Developer Edition on my Linux machine (Fedora 32) as I migrate from Windows for Web Development, but I have hit a wall with it with Gnome Extensions. I get the following error when I attempt to modify or even view extensions.gnome.org content:

Although GNOME Shell integration extension is running, native host connector is not detected. Refer documentation for instructions about installing connector.

The only resolve I found for this is Chrome-based so I do not feel that is the issue I am having. The browser works fine other than this, at least from what I can tell. Is there a way to use the extensions? Should this issue be a precursor to things on Fedora that should keep me on Windows for the browser? Please advise, I want to make the full move to Linux soon.

After removing and downloading Firefox again recently, I have begun to run into characters not displaying on websites. Nearly every site is subject to this issue, where characters display as little boxes with numbers inside them. After looking around, I have verified that I am allowing sites to specify their own font, and that I don't have any fonts blocked under about:config. I am running Firefox 80.0.1 on Ubuntu 18.04.3 LTS.

I am seeing problems identical to https://support.mozilla.org/en-US/questions/1273349

When I click a menu it briefly appears and then immediately disappears.

Turning on "Disable popup auto-hide" solves the issue, but this is a work around not a solution.

Restarting Firefox with a clean brand new profile resolves the problem. So it seems nothing to do with any of my plugins.

But after I click on a link from within emacs, the first time I open a menu it is fine. Then the 2nd time I try to open a menu it disappears immediately. There might be other conditions that do this also, but this is the most reliable way I have found to date.

I believe emacs is calling firefox, by default, using "xdg-open". If I manually use this command from a command prompt to open a web page. It works fine. Huh???

I changed emacs to explicitly invoke Firefox. At first this seemed to have solved this problem. But now it has come back again.

This has been ongoing for some time, over a large range of Firefox versions. Currently I can reproduce with 68.11.0 ESR and 80.0.1

Sometimes I have done something and I think I have magically resolved the issue, but then it comes back again.

This is currently Debian/buster and Debian/bullseye using the i3 window manager. In the past I have also had the same issue with Debian/stretch. I have multiple monitors. I doubt any of this is relevant, but just in case.

Unlike the previous referenced post I have not been able to reproduce this under OSX. Although I don't often click links from emacs either. So wonder if that is significant.
