System Details: Ubuntu 18.04, Firefox 65 Firefox doesn't play any sound on any website,other apps play. Firefox does show the speaker icon on the tab that is playing video/audio

I have tried https://support.mozilla.org/en-US/kb/fix-common-audio-and-video-issues

I think i have this problem from the day i connected my PC to TV through HDMI and played a video on firefox - Maybe firefox is still using the wrong device(HDMI TV)(I have checked Ubuntu Sound Output is set to inbuilt speaker not HDMI)

Can Firefox "cast?" a video from my Linux Mint-Mate laptop to my ROKU ultra device using Ethenet-only connectivity- no wifi available.

Please be understanding . . . This is my first ever attempt to get help, and I'm not sure if I'm doing this correctly. I noticed that Firefox now has a channel-app on Roku. But I only connect to my Roku Ultra streaming device using Ethernet. The Firefox browser which I use is located on my laptop, running Linux-Mint-Mate, distro 19 and it's also connected only by Ethernet to my network: My Roku device and my laptop are connected to the same Ethernet-only home network. The reason I cannot use wifi is that my wifi is too slow - Router is 16/4 and I think I'd need a new, much faster router 32/8, or better. But my laptop is very old and it's unlikely it can transmit wireless signals fast enough for a reliable HD signal anyway . . . I would like to be able to send streaming videos from my laptop, to my Roku Ultra - to my TV. (It is not a smart TV - it's just an old Panasonic Plasma HD TV). I have an NBC Sports Pass Gold - Cycling Pass subscription account which (because of their app's. limitations) cannot play all of the available videos from its Roku channel app, because their ROKU channel app's videos are limited to just the most recent 90-day posted events. But all of the older videos from the earlier part of the season can always be played from their website, directly from my NBC account, which is located only on my laptop. -So this means that I can only watch these older videos on my laptop. My Linux operating system is running on an older HP Elitebook laptop with a duel-boot setup with Windows XP. If it is not possible to send these website-only videos across my network via Ethernet to my Roku Ultra device to my TV, could you tell me exactly what hardware devices etc. I would need to buy to do this successfully using wifi? My wifi speed to my apartment is very, very fast - it uses Comcast's fiber-optic service. Please note; I am only be able to follow very simple, step-by-step answers. I am elderly and I'm just a novice with computers etc. Thank you very much for any help with explanations, and options that I might have to accomplish this. Sincerely, DN24

In my settings I have Firefox set to open PDFs using the app 'okular' (see screenshot). In my file browser, PDFs open in 'Okular' (see screenshot). However, when I click a pdf in the Firefox downloads pane, it opens with 'GNU Image Manipulation Program'. Why is this, and how can I change it to 'Okular'?

I'm running latest version of Kubuntu, with current updates.

Dear Community Support,

    I have problem with Firefox during the save of a file.

it appears the file manager but if I type doesn't search for directory or file. So every time I have to position on directory and Firefox is unusefull I hoped to find a solution with time but now we are at Firefox 47 and I have no solutions...

I tried solutions for different file manager, to change profile, to download a developer edition of firefox, start without add-on but nothing.

Any idea?

Thank you Mario

Wrong offset for the right-click menu → Right-click on link immediately opens link in new tab unless button is held (at least three years old bug)

Hi. There is this at least three years old GUI bug that is not yet fixed, I'm writing this post to show the temporary workaround and hopefully get more interest in the bug itself. This would be an urgent usability bug, but it's still here because probably not everyone can reproduce it.

Link to one of the bug reports: https://bugzilla.mozilla.org/show_bug.cgi?id=1504021


> Description

Removing the title bar doesn't set an offset for the right-click menu → the right-click menu will appear slightly wrong positioned, with its first entry below the mouse cursor → the first entry of the menu will get a mouse-release event and will trigger.

The effect of this can be different depending on what you right-click:

  • right-click some empty area in a web-page: you will be taken back to the previous page (because the first menu entry does that)
  • right-click a link: you will open the link in a new tab (because the first menu entry does that)


> Steps

  • Have a non-maximized Firefox window.
  • Disable the title bar (through the "Customize..." option)
  • Right-click anywhere on a webpage: you will be taken to the previous page.


> Workaround

Enable user styles by setting toolkit.legacyUserProfileCustomizations.stylesheets to true. Create "chrome" folder in your profile directory. Inside, create "userChrome.css", and write:

   #contentAreaContextMenu{ margin: 20px 0 0 20px }
