I am running Unix Ubuntu 22.04 with Firefox 104.0.01 (64 bit). My Canon LBP 6230DW works fine in my word processor and in Chrome, but it does not show up in the Printer destination field when I am in Firefox. The only print option is to "Save as PDF." How do I get the Canon to be a print destination in Firefox?

Hello :)

Firefox 102.0.1 crashes after some Time. Firefox then is unable to switch between Tabs and stuck at the opened Website.

For testing Purpose i start over with a new profile and did not install any Add-ons. The behavior was the same, it crashes after some hours.

My System is Ubuntu Mate (Ubuntu with Mate Desktop) in Version 20.04.

Here has someone the same problem: -> https://bbs.archlinux.org/viewtopic.php?id=277649

Thanks for any suggestions.

When I want to drag and drop a tab into a folder of the bookmark toolbars, I can't do it for some folders.

Specifically, it doesn't work for folders that are somewhat in the area of the tab preview animation that pops up when I start dragging the tab. So that is not the same folders every time, it depends on the tab location in the tab bar.

I hope that the explanation was clear enough, I did a screen record also, made it available here https://ufile.io/pikit6xo (335 kB).

Do someone had a similar issue and found a solution?

I'm in troubleshooting mode. Firefox 100, just updated, but bug was there before. Ubuntu 20.04 LTS

My Firefox installation on Ubuntu 20.04 does not load or render any page, nothing happens when I enter an address.

I have already rebooted multiple times, purged Firefox through aptitude, deleted all files related to Firefox (profiles, the complete .mozilla folder in home, everything else) and reinstalled as suggested in various support platforms. I have started Firefox in safe mode as well.

As far as I can tell the problem started after I used "another" Firefox through my universities Citrix service to be able to access their library catalogue. I had to symbolically link all of the files in the Firefox certificate folder to that of the Citrix client for that client to work, although I've since removed those links as well and it did nothing.

I am really pulling my hairs over this as Firefox is heavily integrated in my workflow and I don't want to switch to Chrome but I also don't want to completely reinstall my laptop as that would mean completely setting up my work environment again too.

HI! I'm using Firefox 98 on Linux Ubuntu 20.04. after the last update I found several settings changed and I had to reset them, but there is one setting I can't manage. In the download preferences I set all the Microsoft Excel entries to "Always ask", but every time that I try to see an Excel file (no download, just open with ...), this is automatically downloaded. I definitively don't want to download it. How can I change this behavior? P.S.: I realized right now that there is the same problem with .docx files and I don't know how many others file types.

Steps to re-create: create a new campagin attempt to change the display image using the hover-button over the image on the page.

What happens: I click the "change image" button, it gives me the os file picker. I select the file i want and click open and the file picker goes away. The "progress" bar at the top of the image shows up, changes through several states it seems. Then all screens freeze, and the computer stops responding to all output.

Supplemental info: This started happening after an update from ubuntu 18.04 lts to 21 to 22.04 lts. So I know I was not using a flatpak before and I am now.

I've attempted to use strace to figure out what's happening at the time of the freeze I'll include a picture of that if this form does not cause my entire pc to freeze. But didn't really get any useful info from that. I tried reading dmesg at the time of the crash but so far the screen freezes before any relevent information pops up. I've not been able to find any logs about whats going in previous dmesg logs.

Troubleshooting steps: I've attempted the same procedure in firefox's safe mode. This does not seem to stop the crash. I've attempted the same procedure using chrome and this works as it should.

Brand new installation of Ubuntu Focal (on an ARM Chromebook, using Crouton). Installed Firefox (104), runs fine but as soon as I sign into my Firefox account it immediately crashes. Continues to crash if I start in safe-mode, so I don't think the problem is an extension. After some online research and some trial and error I seem to have determined that I can sign into my Firefox account as long as password sync is disabled. But as soon as I enable password sync, Firefox immediately crashes.

Error message in terminal is always about GPU, which maybe isn't properly set up or maybe Firefox has a problem with it, but if I use the software renderer it doesn't cause a problem (MOZ_ENABLE_WAYLAND=0 firefox). Hard to imagine that this has anything to do with crashing when syncing passwords?

I can't use any mouse's scroll wheel in Firefox. I've tried multiple mouses and even a trackpad and none of them will scroll. They all work fine elsewhere in the Ubuntu OS, but just not in Firefox. The manual scroll bars work fine and auto scroll works fine. I have tried starting Firefox in safe mode with all extensions and add ons disabled, but that didn't work. I tried turning off the hardware acceleration in Firefox settings and that didn't help either. Any suggestions before I switch browsers?

I'm running version v92.0 (64) on ubuntu 21.04. Firefox would crash upon opening when signed in. It would stay active enough for me to disable the extensions & themes. After doing that it still crashed. I tried going into Troubleshooting mode and it would still crash. I went into Troubleshooting mode and did a refresh. It was still crashing. Finally I signed out of my mozilla sync account and the browser has stayed active long enough for me to type this report.

I've submitted all crash reports in about:crashes, and I'm not really sure what to do next.

Perhaps a local version of the Mozilla Sync profile has been corrupted? if so, is there a way to remove it and pull down the "sync"ed version from Mozilla's servers? What if the version on Mozilla's server's has been corrupted? should I back up the local profile (wherever it is) before removing?

I hope I've given enough information. Please let me know if you need further, more specific information.

I am having issues with opening link for external applications. The application can be What'sApp or Zoom or Slack and when trying to open an external app I get a windows that ask for me to select the application to open the link.. When doing this the only option have I have is System Handler and Choose Application.. Neither option is helpful.. This did not happen with firefox packaged with .deb .. I am assuming that this deal with snap sandbox security.. I later read an article

I did a little reading and came across a link https://ubuntu.com/blog/how-to-snap-introducing-classic-confinement

Which instructed on how to create a snap with --classic confinement.. I am not sure if this will resolve the issue that I am having .. But I didn't find that I could install firefox snap with the --classic option.. I am not that familiar with snaps so I could be completely off but wanted to know if someone could look into it..

I would like to add an image but it doesn't seem like firefox will allow me to on this page. (Browse is not opening a window) Also copy and paste didn't work

Hi all, I'm having a lot of problems with Firefox crashing pretty often. Sometimes once or twice a day.

I most often see crashes in the middle of a Webex video conference for work. But Firefox sometimes goes down in other situations that I see no pattern in.

This is Ubuntu 20.04, Firefox 102.0. Unfortunately, it's a complex environment to debug.

First, when firefox goes down, it rarely leaves a crash report behind. So I'm not getting any direct evidence as to what is happening. Second, I run with uBlock active and it is very difficult to function in the browser without long enough for the crash to happen. Third, I typically have several hundred tabs open. I have a lot of memory (64G) in my machine, and the machine doesn't act like it's swapping, so I don't think I'm running out of memory.

Any help getting to the bottom of what's going on is welcome.

When I click the fullscreen button on a video, such as YouTube or Netflix, I find that upon exiting the fullscreen video and going back to normal screen, Firefox's window size is now maximized, when it was a smaller window before clicking the fullscreen button.

I am running Ubuntu 21.10 and I don't recall having the issue in previous versions.

Loading a web page stopped in the middle. I have checked my internet connection: OK. After that no one web pages was opened in the firefox browser. I have opened Chrome and everything worked well , web pages has been opened.

I have purge firefox installation (apt purge firefox) and installed again. Not helped. I have switched off all the extensions. Not helped.

I have read and followed the things in the article: https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can Nothing helped.

I am using Ubuntu (Ubuntu 20.04.3 LTS) any idea?

Hello, I was trying to fix this issue on my browser but I was not able to do it. The OS is Ubuntu 20.04.3 LTS 64-bit. Currently, I'm using Firefox version 99.0a1 but I had the same issue on version 97. Also, I have this issue on only one of my PCs. As I said in the subject: - The browser freezes the whole PC and I have to force reboot it. (I already disabled the hardware acceleration) - the recent download item open button does not trigger the opening of the folder. - If I try to download a file, the browser ask me where to save it. But if I try to download another one the browser shows me the directory with path /run/usr/1000/... I tried to delete places.sqlite but I received the same result. ... I'm attaching two screenshots also. Thanks a lot!

Hi, Downloading files to a system directory (Linux) such as /home/me/doc/here /home/me/doc/there Have Ask me where to save files checked.

But lastDir is not a real directory I can navigate, such as /run/user/1000/doc/3dcccd48

This causes the user needs to navigate sometimes very long system directory tree for each successive file download.

In about:config I set:

 browser.download.lastDir 
 browser.download.lastDir.savePerSite	false	
 browser.open.lastDir

But every time these are obfuscated to something like: /run/user/1000/doc/3dcccd48

This introduces about 10 user interactions with mouse/keyboard for each file I download in succession.

How do I get FF to stop obfuscating real system directories for "lastDir"

Really really appreciate the help :)

When I use the import feature on the bookmarks bar Firefox doesn't detect the Chrome browser. I get the following message: "No programs that contain bookmarks, history or password data could be found."

The Subject says it. I have this line "Your browser is being managed by your organization." in Config under Sync. I am a private user so there is no organization. I want to get rid of this.

I'm trying to troubleshoot why Google Chat will not sound an audible alert while Google Mail does. I can't find any settings that would affect this so naturally I suspect this organization line.

I'm using the Mozilla .deb and not the Ubuntu snap.

Thanks, John

Hi,

So, it looks like snapd went ahead and updated my Firefox.... Grrrrr

Now I'm unable to access my profile information. (passwords, tabs, extensions, history, etc)

When I try, I get a pop-up telling me that using an older version if Firefox can lead to profile data corruption. However, I'm trying to use FF version 109.0.1 (64-bit), which should be very new.

How can I get my profile data back?

Thanks in advance,

Mike Diehl.

For quite a while I am using Firefox and had no issues, but recently, with new version , I am constantly facing two issues 1. the initial load of a page takes more then 30 seconds , sometimes 1 minute, but after the first page has been loaded if I open another page , it will be as usual 2. Completely random and without any sign of slowing down the OS - the OS freezes - nothing works at all and I have to restart it using the power button. ( and this happens when Firefox is open so I doubt Firefox)

version Firefox Browser 91.0.2 (64-bit) Mozilla Firefox for Ubuntu canonical - 1.0

I am using KDE Ubuntu Linux OS on desktop CPU with Firefox browser.

When I went to sign in to a website. After I entered the user name and password the next step should be that requires a Google 2FA authentication code but the website goes blank. I refreshed site. Still a blank webpage.

The website will open correctly as expected using my Android cell phone using Firefox browser. Which is also where I have the Google Authentication app installed.

I had to use Brave to open the website. I am told by others Google Chrome will also work but I try to avoid both these browsers.

I have not added the 2FA sign in to Firefox main sign in yet. I intend to switch over to a Yubikey 2fa in the near future.

Any ideas?
