On ubuntu 20.04, the snap version of firefox can't play some videos. Some youtube videos will play but streams won't, and then I get the message "to play video, you need to install the required video codecs". On telegram web and tweetdeck I also get this message while trying to play some video.

Since it's a snap, nothing I do on my system will solve the problem, I cannot install any codecs.

It's firefox 89.0

Hello,

I am looking for a way to hide my tab bar when there is only one tab open. I almost found the solution there: https://support.mozilla.org/en-US/questions/1297983 But it is not exactly what i am looking for. This solution hides the tab but not the tab bar it self. I mean it leaves some black empty space because i use dark theme.

I kept looking for a solution to hide the container. I found this one: https://support.mozilla.org/en-US/questions/1271391 The problem is: this solution hides all the time the tab bar. No maters how many tabs opened.

I experimented mixing these two solution. I have try:

  1. tabbrowser-tabs tab[first-visible-tab="true"][last-visible-tab="true"] + #mainwindow:not([tabsintitlebar="true"]) #TabsToolbar {
 visibility: collapse;

}

I tried the other way around, with "#mainwindow" first. I tried without the "+" sign. But none worked out.

I'm running Ubuntu 20.10 with GNOME Shell extension Unite which can add the minimize, maximize and close buttons to the top bar and remove the buttons from the title bar of apps. The does not work in Firefox, minimize, maximize & close remain. I'm assuming this is related to Firefox's ability to remove the title bar all together so tabs can be at the top. The Firefox Customize... page allows you to change just about everything else in the UI except these three buttons.

Is there a way to remove Firefox's minimize, maximize and close buttons?

In case it matters I really only care about the Close button (not Close tab) because GNOME Tweaks lets you remove the minimize & maximize buttons from all apps.

Thanks

In Ubuntu 18.04, I bring up a new page, click in the search bar in the middle of the page. Then when I start typing it jumps to the address bar although I have already placed and preferred the search bar to the right. No! NO! NO!

I use Duck Duck Go but Google does the same.

It is bad enough that the upgrade was automatically loaded but on top of that, changing preferences including dumping my home page. Change privacy settings without asking ( to a lower level on top of that ).

Really POOR form.

We have a new add-on of our own that we were trying to add to the Firefox browser. This add-on was tested locally and worked fine. However, upon trying to install the official add-on to the browser, it is throwing the following error, "Installation aborted because the add-on appears to be corrupt".

The add-on in question is, https://addons.mozilla.org/en-US/firefox/addon/searchgiggle-search/

Any suggestions to address this issue would be appreciated.

I also noticed another post or two about the same topic. As per those posts, the issue got resolved automatically after some time. Can I expect the same?

I just reinstalled my operative system, and with that my Firefox settings got reset. I know there is an entry in about:config to prevent ads from opening new tabs and pop ups without authorization, even from legit websites like the login pop-up windows when doing a sign in in Google, in those cases to allow the windows it's needed to click on the lock icon next to the URL bar and allow it from there. The problem is that I don't remember the name of that setting and I have spend an hour looking for it on Google.

Firefox does not load any pages or settings or login for firefox account

Hi everyone,

Thanks a lot for taking time reading this! :)

I have the following problem with my firefox on Kubuntu 20.04 on my laptop: since a couple of weeks, firefox opens normaly after rebooting, remembered all tabs and my firefox account etc., but it's just not loading anything. I can still type in a web adress or something in the search, I can also still select the drop-down menu on the right ("Open menu") and select e.g. "Settings", but nothing happens afterwords. Same problem for all websites. Some of the main buttons are also not functional (refresh, back/forward). I attached a screenshot from the "empty" firefox (but not sure if that's of any help anyways ;) ).

I tested a couple of things so far, nothing helped:

1) Internet is working, I tested ping, apt is working as well as a differnt browser I installed now).

2) I reinstalled firefox completely by running the following commands:

      sudo apt update
      sudo apt purge firefox // sudo apt --purge autoremove firefox
      sudo rm -rf .mozilla
      reboot
      sudo apt update
      sudo apt install firefox
      (Since I removed the profile folder, the standard tab and bookmarks open/show after starting firefox now, as expeced. I'm also not longer logged in.)

3) By starting firefox via the console, no error messages were shown

4) I created a second ubuntu unser profile, to test if firefox would work there: it doesn't

5) Since I have a dualboot with Win10/Kubuntu 20.04, I started Windows and tested firefox there: it is working as usual.

6) I also obviously tried to google this problem, but either I put the wrong keywords in or this problem is pretty unique/new?

If you need any further information on my system, I'm happy to provide them! Thanks a lot for any recommendations and further ideas, what to do! I'm pretty much desperate for a solution by now, as during home office a not well working system is a pain! ;)

Thanks and stay safe, Katrin

Since installing the latest Firefox update I have been unable to view Amazon Prime videos. I keep getting this error message: Digital Rights Error Your web browser is missing a digital rights component.

In your web browser's address bar, type about:addons, press Enter, and then on the left, click Plugins. For the Widevine Content Decryption Module, select Always Activate, and then refresh the video's page and try watching the video.

If the video doesn't play, go back to Plugins, click the gear icon at the top of the page, and then click Check for Updates. When the plugins have updated, refresh the video's page, and then try watching the video.

I had no problems with the previous version of Firefox. I am running in Linux Mint 20.1, Firefox 89.02, 64 bit.
