Maximizing and minimizing are still normal, but Firefox windows could not be dragged now.

I saw where this was a problem with Netflix, Amazon Video and other sites with Fire Fox and that one person even used professional version and still had the same problem.

What I cannot see is where he got the video codex that allow Netflix to work on Fire Fox version 88, let alone this newest version that Mozilla has created.

Problem: Scrolling in firefox is feeling weird: instead of smooth scrolling with 2 fingers (like on smartphone with 1 finger) firefox scrolls only by steps only when I move my fingers enough to trigger scrolling. In other applications I can scroll smoothly and fully control scrolling, I can scroll exactly N pixels if I want. In firefox I can only move by N pixels per M cm fingers movement on touch pad.

It's feeling as indirect input. I can feel same feeling on Windows with simple mouse. Firefox scrolls slower than Opera.

How to reproduce and find difference with other applications:

1. Download Firefox and another application with direct input (Opera or Telegram for example)
2. Scroll Firefox
3. Scroll another application

Hi there,

I'm using my PC for local web development. I use Firefox as my regular browser and recently, in order to distinguish between personal time and development time, I've established a new profile just for development purposes.

The local website I can't reach is "site.local.dev". My OS is Ubuntu 20.04 and that URL points to a local IP on my network (resolved via /etc/hosts file on my PC).

Funny thing is that: - In dev-profile: site.local.dev does not work => "Unable to connect" and the URL bar shows https://site.local.dev even if I force it to http:// - In personal-profile: site.local.dev does work :P

I have tried with CLI tools like "wget", "hosts", "ping", "telnet" and so on and the site loads ok. Even I have used Dillo (damn simple web browser) and the site loads ok also.

Things I've tried so far: - Suggestions at https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can - Suggestions at https://support.mozilla.org/en-US/questions/1011327 (similar issue, not exactly the same).

It must be a silly thing but I'm out of options now. Perhaps anybody has faced to this situation in the past: any suggestion on this issue?.

Thanks in advance, Ibon.

Hi,

first of all thank you all in the community for your amazing work on Firefox!

I have cloned my $HOME (including ./.mozilla/firefox/) to another Linux device.

Now I realize that changing the Firefox Sync device name on the new device would also change it for the other device when checking "Connected Services" https://accounts.firefox.com/settings. I also can only see the new device name when using "Send to device" from any device.

I guess I have to unlink my new device and somehow assign it a new device ID for Firefox Sync to recognize the new device. How can I do that?

I've got FF set for https-only. But sometimes it will tell me no https is available but when I go to the site anyway it is https.

Is this a bug or is this something in my settings?

Using Mozilla Firefox 108.0 for Ubuntu canonical 1.0 on Ubuntu 20.04.

Thanks.

Greetings:

First experienced: Friday, Sept 2, when using burpsuite/foxyproxy during a hackerone CTF.

When using other Vbox instances on the same computer I have the same issue. This issue is usually easy to duplicate when using dev-tools or by simply doing an image search and moving the mouse across the images.

Host: Ubuntu 22.04.1 LTS 5.15.0-47-generic #51-Ubuntu SMP Two different VGA controllers are present: Intel CometLake-S GT2 AMD/ATI Ellesmere Radeon RX

VirtualBox: 6.1.34_Ubuntu r150636 (Qt5.15.3) VirtualBox VGA: VMware SVGA II Adapter

Guest: Kali 2022.3 rolling 5.18.0-kali5-amd64 #1 SMP PREEMPT_DYNAMIC Debian 5.18.5-1kali6

Crashes have seem to involve input from the mouse and scroll function within the browser. Once, let us call it a glitch, the crash can either take place while continually moving the mouse around the browser's page or immediately outside the page with the mouse. The "glitch" is a coloration, usually pink or lime-green with characters printed to screen and then disappears. I have been unable to predict when the glitch will happen, thus no screenshot to help.

Steps I have taken:

Googled on the problem which led me to learn about the Firefox about:crashes function.

Viewed about:crashes -- seems to be a Renderer issue linked to llvmpipe or Mesa?

Checked basic system logs for host and guest for anything evident: syslog, kern, Xorg, messages, dmesg, daemon, journalctl.

Used Firefox troubleshooting and extended troubleshooting.

Installed Firefox 104 with same issue.

Reinstalled VirtualBox.

Search on Firefox Renderer issue [from crash report]

     I turned off performance settings, still have same crash issue.

Last Report ID that did not fail to upload: bp-740acc47-0ed4-44a8-851c-ff21b0220905

Ultimately, I am unsure if this is a Firefox, VirtualBox, or Kali Linux issue, but Firefox is the one that this issue is having a severe impact on. My head is spinning at this moment due to all the logs and information I have digested over the weekend.

I appreciate any efforts in helping me decipher what is going on!

Respectfully,

Steve

I am experiencing problems when using Duolingo, which is highly interactive.

This same problem was highlighted in Version 95.0.2 from a Windows user. The waveforms on System Monitor/ Resources are the same.

I am using Fedora and have 16GB ram. Have just ordered another 16GB ram, but think this problem is so severe that no amount of ram will fix it.

Hello

We have lost our developer access to manage an extension. Nobody knows which email address and account was used to manage the extension.

What is the procedure to get ownership of the extension ?

Thanks Frédéric Jahard

Firefox unter ubuntu 22 hat keinen Zugriff auf die lokalen Dateien (z.B. /usr/share) Der 'open' auf '/usr' scheitert mit 'read'-Zugriffsrecht.

Ganz egal, was in '/etc/apparmor.d/usr.bin.firefox' respektive in '/etc/apparmor.d/local/usr.bin.firefox' spezifiziert wird, das Zugriffsrecht für '/usr' ist immer 'read'.

Wie kann man auf die Dateien unter '/usr/share' zugreifen?

Mit freundlichen Grüßen

I really often need to copy/paste from a terminal opened in my browser. Because the shortcut for copying in a terminal is always Ctrl+Shift+C, it's a mess to have instead Firefox opening Inspector from devtools.

How can I disable this shortcut ?

I've tried to update some about:config settings but it doesn't seem to be helpful and old working correctives add-ons are not supported anymore.

I have different login forms on different sub domains so I always get a huge lists of different logins. and also I get my password for the basic auth from the web-server on my login form.

I also consider this as a security risk when different sub domains belong to different parties and I accidentally put my password into the wrong form.

Can I config Firefox the way that I get only passwords in the list that match the exact url or at least the (sub)domain?

Another Question As a Web-developer can I do something that my client don't experience such a mess (like giving the login form a special id so passwords are restricted do this particular form.

When I start entering an address or a search term into a new tab or new window I'll get "Search with Amazon" as top suggestion. How can I remove "Top Sites" suggestions on recent Firefox versions?

https://support.mozilla.org/en-US/questions/1285677 the solution proposed here, is not working anymore.

I'm trying to install Firefox on a Chromebook. I've done this successfully before. Using the instructions in the Mozilla page https://support.mozilla.org/en-US/kb/run-firefox-chromeos?utm_source=www.mozilla.org-firefox-browsers-chromebook&utm_medium=referral&utm_campaign=seo#w_installing-the-firefox-desktop-browser-with-flatpak

But the command in the terminal window sudo bash -c "$(curl -fsS https://raw.githubusercontent.com/mozilla/sumo-kb/main/run-firefox-chromeos/install-flatpak.sh)"

Is giving me the error message curl: (22) The requested URL returned error: 404

Any advice would be appreciated! This is a fresh ChromeOS environment since I just did a factory reset so everything should be clean, and with latest OS version.

Thanks

Hi,

Is there any reason firefox would flag an mp4 file legitimately?

• The file extension and file type are absolutely mp4.
• There seem to be no mp4 related zero days.

Does Firefox perhaps just treat all downloads from suspicious domains as malware? Is there a zero day I missed? Is this based on some missing metadata on the file or something?

Thanks for any advice you can give here, I'm scared.

I have a linux debian 11 o/s with up-to-date Firefox I don’t know which version at the moment it is whatever debian repo pushes down. I have 5 profiles on this particular computer with no previous issues. I decided to create another profile to be used for some test work and when I created it I then launched it and opened a few tabs to make sure it worked then closed. I planned on copying the profile files from another profile into this one so I went to the profile folder - /home/user/.mozilla/firefox/profile.names

Once there I saw my other profiles but could not locate this one so I went back to an open browser where I had the about:profiles page open and decided to delete that new profile and start over I figured maybe I accidentally saved it to a different directory. I hit remove it and it gave me the box asking if I wanted to remove files I chose yes I then go back to - /home/user/.mozilla/firefox but folder firefox was gone with all of my profiles all that was left in .mozilla was - /home/user/.mozilla/extensions and - /home/user/.mozilla/systemextensionsdev. Both of these folders - “extensions” as well as “systemextensionsdev” are empty. I go to the local directory for each profile and the data is still there for each of the profiles - /home/user/.cache/mozilla/firefox/profile.name.

The recycle bin is empty. A system-wide search for the profiles comes up with just the ones in the .cache folder. Back at the about:profiles page any attempt to open the preexisting profile results in a prompt asking me to create a new profile. I still have the one profile open and the addons are not working correctly. I did a bookmark export on this profile and doing so generated the “firefox” folder that had disappeared plus a profile folder using the same name of this open profile - /home/user/.mozilla/firefox'profile.name - it created a profile folder for this open profile using the correct name.

Any ideas on how this happened? Can the local profiles still in .cache be used to somehow restore the full profiles?

I've installed a new version of Ubuntu Linux and - as recommended on this page's FAQs - backed up my firefox profile, than copied it into the profile folder on the new os. Now Firefox tells me "You've launched an older version of firefox" and forces me to create a new profile :( Also loading the old profile in "about:profiles" leads to the same result

How can i restore at least my passwords? (When i try to copy only 4.db and logins.json from the old to the new profile, i get the same result)

I can't find an "import old profile"-function anywhere...
