Compatibility: an increasing number of websites and features do not work in Firefox on Linux

I believe everyone has a right to choose the browser and operating system they use. I choose to use Firefox because I care about my privacy, and because of features like multi-account containers - as a software developer these are non-negotiable. I choose to use Linux for similar reasons, and many Linux distributions come with Firefox preinstalled as a default browser. In light of recent changes to Google's data collection through Chrome, I am more than ever committed to using Firefox as my only browser.

However over the last year or so, I have noticed an increasing number of websites or features on websites have stopped working in Firefox on Linux, forcing me to use Chrome against my wishes. Examples include the entirety of the Australian government's MyGov website; the phone call feature in Slack; and Google Meet meetings (no audio). I know people who use Firefox on other operating systems and they have not had these problems, so I can only assume that the issue is specific to Firefox on Linux.

I am not trying to suggest that Mozilla is responsible for this in any way - if Google or Slack or the government refuse to support Firefox on Linux, that's their responsibility, not Mozilla's. However, I am not convinced that the lack of support is intentional, or that it isn't a quirk of the particular Linux distribution I use or the version of Firefox included in the package manager. Any advice would be appreciated.

My Firefox version is 84.0.1, and my Linux distribution is KDE Neon User Edition 5.21 which uses Ubuntu 20.04 under the hood.

See the attached screenshot. the function is mostly useless as-is now.

This is on Firefox 87 Manjaro 21 (Linux)

Default theme is used.


According to https://www.reddit.com/r/firefox/comments/8k3sq4/firefox_updated_to_6001_and_the_search_box_is_no/ there's something wrong with userchrome.css in the profile but that file should be patched if that's the case.

Why this hasn't been patched since it's introduction in version 60 is beyond me.

So I just want to understand is there is anything new since this post or do I have to apply a more efficient solution that removing user.js I don't want to take the risk of spoiling up my setup.

When I type in ANY URL, I want exactly that to be loaded. And not anything else.

When I type in mozilla.rog into the address bar, I want firefox to fetch the page mozilla.rog. I want firefox to try, and if it does not exist, I demand to be notified that it does not exist. With an error message. URL not found. Error 404.

But instead, Firefox silently changes mozilla.rog to mozilla.org (and probably any page e.g. from .rog to .org, and from .ocm to .com , and the like) without my permission, and loads this other page I did not type in.

I do NOT and NEVER allow ANY program to alter my commands without notifying me.

so... which about:config setting disables this autocorrection-behavior?

My Mozilla occasionally crashes on various websites but this is rarely a big deal and is usually restored without further problem. However, when trying to access my online banking (Co-operative and Smile) it crashes repeatedly after a few seconds, making these sites unusable. Anyone got any ideas why this specific site is a problem and how to overcome it?

My cookie cache is erased every time firefox closes and I only have Ecosia as an Add on. My security setting was strict but I changed it to standard. This had no effect. I'm not very familiar with Linux so a simple explanation would be appreciated!

Thanks in advance

P.S; The crash reports fail to submit. I don't know if this is related.

On Ubuntu, FFDE can be configured to

1. Auto-update - but it just displays a message saying that it cannot update

2. Download updates and request permission to install them - all it does is display a message saying a new update is available

I think this all stems from the fact that FFDE at present has to be manually installed on Ubuntu. Why this is so, I cannot fathom - maybe someone here has an answer to why open sourced op system users are inconvenienced by Firefox.

It's feasible to script an update procedure to Ubuntu for FFDE. But this will not stop the annoying (every 2 hours) pop-ups about new updates being available - even when there is no new update there . . .

Maybe FFDE could simply stop automatic update reminders altogether. Users can decide (or script) for themselves if they want to update.
