And neither is the Temporary Containers Addon. I just did fresh brand new initial Firefox install on both the most updated version of Windows 10 and the most recent version of Ubuntu 20.04. All addons appear in the toolbar except these 2. I've tried installing these 2 first. I've tried installing them last, then disabling all the other addons, uninstalling them and reinstalling them. Nothing will make them appear in the toolbar, yet they appear as enabled when they display under the addons > extensions. Also, hitting the extension shortcuts will not bring up the addon interaction screen for any of the addons, e.g. Ctrl U or Ctrl <period> or whatever the relevant shortcut command is. This appears to only be an issue with FRESH Firefox install, because on my other computer running Windows 10 I've had the Multiaccount Containers Addon in the toolbar for 6 months without issue through many older versions of Firefox; and after I updated (rather than fresh install) to this latest version the Multiaccount Containers Addon remains in the toolbar without issue.

Can anyone suggest how I can get theMultiaccount Containers Addon and Temporary Containers Addon to appear in the toolbar? And why are none of the extension shortcuts working - could I be executing them on the wrong screen? I've been trying them on the Addons > Extensions screen.

Dear audience

I have troubles that when I copy Firefox profile to another computer, the web extensions does not work.

Sometimes helps to restart Firefox to safe-mode and then back to normal. But always works when on a new computer I disable extensions and enabled them back on.

If I remember correctly, this behavior started with Firefox 68.

OS: Windows 10 Firefox: 77.0.1, 64bit, English

Do anyone know why this is happening, and hot to correct it? Is there any preference that should be modified?

Thank you and cheers

Hi. I am running Firefox for Android 68.10.0 and I am connecting to an Apache2 server on a Raspberry Pi. I have a page that displays family photos. On Firefox, some images appear rotated 90 degrees. The same images are fine on DuckDuckGo - see image. Any ideas on what I am doing wrong?

When I press new tab, screen opens with Google as search, even though I'm in FF. In all honesty, the get started function is the worst I've ever seen. Where is drop down menu for extensions?

I will create code that will hide/show the webpage icon(favicon) that is next to the page title on browser tabs. Is this possible to do by configuration options or addons?

Firefox won't load my Google profile on a Blogspot site I read, so I cannot leave comments, which I used to be able to do. I can go to this site via Internet Explorer, and that does work -- my google profile loads right up and I can post comments. What do I need to change in Firefox so that my google profile can be seen by this site?

i am using firefox on a Linux debian based distro, I am facing difficulties changing the size of the menu e.g width, height and font. I have tried to play with the about:conf > layout.css.devPixelsPerPx value but that did not change a lot for the menu size. so please tell how can I fix this (I am trying to make it smaller) note it is same case when I use firefox-esr for linux as well.
