We are deploying Firefox installed via the v122 binary on Ubuntu 22.04.4 Server w/ubuntu-desktop-minimal --no-install-recommends (we need to have no-user-interaction install). We are using an Ansible playbook to copy over and unarchive the tarball, then create a firefox/distribution folder in the install directory and copying a profiles.json file to said folder, links the install directory to the /usr/bin/local directory, and setting firefox.desktop as the system default browser.

Using the instructions from: https://mozilla.github.io/policy-templates/

What we are hoping to accomplish is the user who has never launched Firefox will click on a link in an application, which will launch Firefox and go directly to the requested page. As it stands right now, the first time a user clicks the link, it launches firefox and shows a start page. The user must then close this window, and click the link again. This brings up a "Use Firefox as the default browser" prompt, which the user must accept, but then does not display the link. The third time the user clicks the link, the requested page pops up, and works from this time out.

We would like to have this be a one-click experience for the user. Looking at the options in about:config after getting firefox to launch, it appears firefox is not getting the options from the profiles.json file. Are we missing something about placement of this file? Missing some lines? Should we be using AutoConfig instead? Thank you for any assistance!

When I try to access my payment preferences page on xfinity.com, the page goes blank and it appears that it is being blocked. I can't figure out how to unblock it. I had to use Microsoft Edge to access the page to change my information. Can you please assist?

I am no longer able to add attachments to gmail or upload images or attachments to websites. When I click on the attachment icon or upload button, my finder window does not open. However, it works in other browsers. How can I fix this?

Today when I close many tabs using control w firefox seems to randomly jump around when choosing which next tab to close

I wish to have firefox always close the adjacent tab to the tab I just closed

This should be the default behavior ... I do not see any setting for this ... is there an addon to do this ?

I am using the latest firefox on ubuntu

• • • UPDATE*** below answer for setting `browser.tabs.selectOwnerOnClose` has no impact on this

Why can't Firefox copy text to the clipboard anymore? It won't copy text from a web page, from a URL, or even from about:support "Copy text to clipboard"!!! I'm using version 1.22 64 bit on windows 11. I've reinstalled Firefox but it doesn't make a difference. I've tried "Troubleshoot Mode" and it's still broken!!!

I can paste into Firefox but something has broken copy!

How to reproduce the bug: Jump to the address bar, and then press shift, ctrol, alt or windows_start, you can see the address getting deleted. You can also see it in Google Sheets and Microsoft Excel Online, it just deletes the cell, or a selection of multiple cells. --Interestingly on Google Docs it doesn't delete but just move the cursor to the first character when a string is selected.

 It happens only once per mouse click, or focus change

What I expect: Shift, Control or any mod key should not delete content or move a cursor

Thanks!

When composing emails in Gmail holding down a (any) key does not activate key repeating.

Also, the there are irregularities when using discover.com in Ver. 124. When editing my customer profile, keystrokes are not recognized. Nothing happens when typing. I also had difficulty signing-in; this may be coincidental.

Things tried: (1) A different keyboard. Same results. (2) Firefox version 122. The key repeat function worked in Gmail. I could edit my profile at discover.com. (3) Uninstalled and reinstalled ver. 124. All problems persisted. (4) Ran Ver. 124 in troubleshooting mode. All problems persisted. (5) Launched newly downloaded versions of both 122 and 124 (from command line) and ran them simultaneously. The problems persisted in 124 (troubleshooting mode), but 122 worked well. I used two different keyboards with no difference noticed. (6) Downloaded and ran Chromium. All worked well.

My default search engine was Norton Safe Search but now it does not appear as one of the options to choose. I cannot remember all of them. Bing and Google are two of them but not Norton Safe Search although I have been able to add it to the toolbar. Why is it no longer one of the options?

While hovering over a Youtube video it shows the full video title as "hover text" if the tab is focused. However, if something else, even another Firefox window is focused hovering no longer shows anything. Is there some kind of setting to change that? I figured it could be browser and Youtube specific because Chrome shows it on Youtube even when not focused, but neither browser shows it on Google search for example, but I'm not sure.

Firefox will not allow my to post comments on Yahoo. I have no issues with Chrome or Safari. I get the following error message: Your comment failed to publish. Retry

You may have heard about this, Youtube (and parent Google) have recently declared war on adblockers and non-Chrome browsers. I have reason to believe they have escalated that war to deliberately crash non-Chrome browsers, at least slowing them down to make them non-responsive.

In the past few days, browsing Youtube has caused my system to stop responding requiring a power cycle to clear the problem.

Has anyone else encountered this problem? Is this just a bad setting, or is Youtube acting as malicious as I believe them to be?

Hi, I have a problem with my firefox app. Everytime I play or skip a port of a video, it plays stuttering and return normal only If I rewind some second (if I pause it nothing change). Anyone knows why? Is there some way to solve this problem? I have deleted every data, cookies etc, every add-on and reinstalled the app but nothing changed. I also formatted every setting of my device but same result. Oh, also, this problem don't happen with other apps like gallery or chrome video (I hope bitrate doesn't cause problems).) .

I use several add-ons in firefox, and largely they feel trustworthy, but I dont have any means for limiting the scope of what they are able to do, the manifest tells me what they can do and thats it. I have read through this page https://support.mozilla.org/en-US/kb/permission-request-messages-firefox-extensions, but I have had a hard time even understanding which permissions let an add-on make network requests.

Barring the ability to actually stop add-ons from making network requests is there any visibility into what requests are being made by an extension, or all extensions in the browser?

After I log in to Linked in I can not use profile or network pages, as it looks like some kind of semitransparent overlay is displayed above them, preventing me from interaction with the page. In the same time home feed is working fine. I tried disabling all extensions but no luck.

Please provide a native way to change the behaviour of Ctrl-W. I tend to switch between aZerty and qWerty keyboard layouts, as a result I sometimes hit ctrl-W when I would like to ctrl-Z some change. As a result I tend to lose some work when the tab I'm working in closes. It would be nice to be able to rebind some of the default key combinations, or at least disable them.

I found a method description that edits the omni.ja file, but also that this method is unsupported. Moreover, running ubuntu kind of rules this out as an option, as canonical has ruled that firefox is to be installed via snap, in a read-only data store.
