Firefox Community Forum

I am running Firefox on Kubuntu, which means it comes pre-installed as a Flatpak.

I was having problems with various web sites so I decided to try using the version of Firefox installed with the file found here - https://www.firefox.com/en-US/thanks/

There were no problems with the install. This version of Firefox showed the same issues as the Flatpak version, so I blame the web sites.

Now I have two versions of Firefox. I would like to remove this second version but all the methods I've found do not remove it. I can certainly disable it by renaming the directory created in my user directory /Firefox. Trouble is, shortcuts I created to web sites always launch this version rather than the Flatpak version and I can't find a way to get the shortcuts to use the Flatpak version.

AV1 Hardware Acceleration stopped working. In about:support->Media->Codec Support Information Firefox states that Harware Decode AV1 is supported but it uses only Software Decoding. AV1 worked perfeclty before in Firefox, is still working in other browsers and apps in my system.

Hey there Mozilla team, Love the new free built-in VPN for the browser and Kit. :D But I have problems with enabling the VPN. I am on Linux Kubuntu and the VPN cannot start. Funnily enough when i turn on Mozilla VPN on device level the Browser VPN does manage the enable itself.

Also I have a question about the Mozilla VPN browser extension. Is support for Linux still being worked on? And could we see the support being implemented soon?

Have a wonderful Day

I've disabled HTTPS only mode. When i enter a local http://server.localdomain server Firefox upgrades that to https://server.localdomain. How do I disable that?

replaced a windows 10 laptop with a Linux Mint 22.3 laptop. Used Sync to transfer profile to the new laptop. Logged into the banking account (BECU.org) successfully. When trying to transfer money from checking to savings, the transaction failed with a statement that the date was invalid. The date was valid. A separate Linux Mint computer that never had a windows profile synced does not show this problem. Disabling all extensions did not fix this problem.

I recently switched operating systems from W11 to Linux (Zorin), and installed a new copy of Firefox. I rely on local web pages I have written for some of my work, but the new copy of Firefox does not find the file. For example, when accessing an image, e.g., file:///magrathea/dmpase/home/index/coastal24.png, Firefox gives the message:

File not found Firefox can’t connect to the server at local file What can you do about it? Check to make sure you’ve typed the website address correctly.

The address is correct, that is, the file resides at: /magrathea/dmpase/home/index/coastal24.png and the user does have permissions to read the file. I've tried adding up to five '/' characters to the beginning, and I have turned off all of my installed add-ons, but without success.

An apparently related problem is that double clicking on a '.htm' file also changes the address, for example, from '/home/dmpase/Desktop/index.htm' to 'file:///run/user/1000/doc/f07a8988/index.htm'

And finally, the "Brave" browser is able to read the files with no errors.

How do I fix this for Firefox?

Running Firefox in Kinoite - whenever I set a page to Reader view it is blank.

I have restarted in troubleshooting mode and it works, so I followed all the steps to try to identify what the problem is but nothing has worked.

I tried:

- Troubleshooting mode - worked - Disabling hardware acceleration - did not work - Disabled all extensions - did not work - Switched to default theme - did not work

Anyone any ideas?

TIA

I'm stuck in an endless loop in Firefox for Linux (MX Linux) whenever Cloudflare is used as security.

"Performing security verification

This website uses a security service to protect against malicious bots. This page is displayed while the website verifies you are not a bot."

I click "verify you are human" and it just loops back to the very same challenge. It isn't broken in other web browsers like Vivaldi for Linux. Or Firefox in Windows 11. Just Firefox for Linux.

It has been this way for months.

4 rows of links working great and sync killed it all. Data is in the prefs.js file but firefox wont read it how can I fix this? Hours I have been chasing around with ai checking all the settings etc. wth? HOW HARD DOES THIS HAVE TO BE? please help before I uninstall and never come back. Wasted way too much time!

When uploading files with Firefox, I click the upload button, and the file browser window appears to upload files.

For as long as I can remember, it always defaulted to the last folder location that I uploaded a file, but just a few days ago, it stopped working, and always defaults to my home folder.

How can I make the upload window pop up, default to the last uploaded location? My OS is Linux Mint Cinnamon.

I like having the shortcuts to regular sites on the home page, but its usefulness is spoiled by every site I momentarily visit also appearing and replacing my pinned sites. This renders it basically useless. Can we please have a way of removing 'visited sites' from the shortcuts.

I currently live in the UK & Firefox defaults me the UKs common sociatal date format D-M-Y, due to having the language set to British English (GB) but the UK also uses International Date Standard ISO 8601 YYYY-M D & I have used this exclusively for the past 20+ years. My computers OS is set to the international standard.

Is there a way to set Firefox to use this date standard? I'd be happy to set the date region to Japan & have it in Japanese, they use International Standard & I lived there for many years, so that would be an acceptable option.

I used to have the email shortcut with protonmail ekb155@pm.me When I try to login to move my shortcuts to Linux, it no longer lets me login without validation to that email. The suffix... pm.me is shortcut for protonmail. When I downgraded i kept my main login, kbarnsda@protonmail.com My current address is kbarnsda@gmail.com

Is it possible to free up this snag, I have always used Mozilla since the beginning of time. I dont want to switch t o Brave which did allow me to change emails.

Any suggestions please Thanks said more simply.. can you change ekb155@pm.me to my new email kbarnsda@gmail.com please for your security chaps the old email ekb stood for everett kenneth barnsdale and pm.me was shortcut email for protonmail.com

I am on Linux using Firefox 140.99.0esr.An entry in my name has the wrong state,i cant tell which one.. I cant scroll to the right to fin d it and i would just like to be able to search for bogus entries using a standard text editor

After the version 149, a very strange issue happens to me with Firefox. When I try to log in to some services (Google account, WhatsApp, Mozilla account) the browser freezes. That does not happen if I turn the hardware acceleration off so I essentially thought there is some issue with my graphics drivers which I then updated (Nvidia 580.142 drivers for Geforce GTX 960). But what is very strange is that the issue isn't present when I use Firefox in private mode! That means: Normal mode, HW acceleration on -- freezing Normal mode, HW acceleration off -- not freezing Private mode, HW acceleration on -- not freezing I switched to the ESR version now which works fine too. Still, I am curious about what is going on and I would like to find a solution. My system is fully updated Arch Linux. I cannot share my data since I can't log in to my Mozilla account. Thanks in advance!

I am unable to download large files from an MS Sharepoint account in Firefox. Small files are fine (less than 100MB). Large files download fine if I use MS Edge browser but I don't want to have to use Edge unless absolutely necessary. Using Firefox Troubleshoot mode doesn't help. Clearing the cach/cookies etc doesn't help. When downloading a 600MB file, the download repeatably fails around 90-100MB. My OS is Linux Mint xfce64. Obviously MS doesn't like firefox for some reason, even in Troubleshoot mode. thanks in advance for any help.
