I-Firefox Isithangami Sokwesekwa

Hi, so I recently installed arch Linux and want to use Firefox as my browser. However ever since I installed it, it takes a long time to launch the program. It consistently takes just over 26 seconds to launch. After it's open everything works fine besides that. Also when I launch Firefox from the terminal I get this message "ATTENTION: default value of option mesa_glthread overridden by environment. ATTENTION: default value of option mesa_glthread overridden by environment. ATTENTION: default value of option mesa_glthread overridden by environment. ATTENTION: default value of option mesa_glthread overridden by environment. Missing chrome or resource URL: resource://gre/modules/UpdateListener.jsm Missing chrome or resource URL: resource://gre/modules/UpdateListener.sys.mjs" I have been looking at some help threads but I can't make sense of what they are talking about. Hopefully this makes some amount of sense to you.

This was going to be a question about Firefox being unable to display the file picker dialog, but I managed to find a solution that worked for me along the way. Since it was nowhere near the top of Google's results, I thought I'll share my solution in the hopes that this would help someone facing this same issue.

The hardware:

• Asus UM425IA Zenbook (AMD Ryzen 7 4700U CPU)

Worked in:

• Ubuntu 20.04 LTS
• Firefox provided by APT repository
• Xorg display server

Not working in:

• Ubuntu 22.04 LTS
• Firefox 99.0.1 provided by snap
• Wayland display server
• File picker worked briefly on fresh install, but something (not sure what) quickly breaks file picker functionality

The symptoms:

• Firefox stopped being able to open file picker dialogs
• Right clicking an image and selecting "Save Image As..." does nothing
• With forms that accept file upload (such as on this post question page "Add images (optional):"), clicking "Browse" does nothing
• File downloads work correctly when set to "Save files to ..." under Settings, but nothing happens when set to "Always ask you where to save files"
• No response to "Ctrl + O" open file shortcut

Similar questions and solutions:

• Fixed by reinstalling Firefox
• Fixed by resetting Firefox
• Fixed with a restart on a Mac
• Fixed by downgrading to Ubuntu 16.04

Things I tried that did not work:

• Disabling hardware acceleration
• Starting with add-ons disabled
• Troubleshoot mode
• Clearing startup cache
• Clearing cookies and site data
• Clearing history
• Refreshing Firefox
• Creating and using a new profile
• Deleting the `xulstore.json` file from the profile directory
• Toggling all permissions under Ubuntu Settings > Applications > Firefox to off and then back to on
• chmod 777 ~/Downloads
• Disabling native file picker "ui.allow_platform_file_picker = false"

And finally, what fixed it for me was to go into "about:config" and change "widget.use-xdg-desktop-portal.file-picker" from "2" to "0". Credit to this post that clued me in.

I really hope this saves someone else 2 days of hair pulling and I would appreciate advice from someone more knowledgeable than me on:

• Why this fixed the problem
• Whether I should be opening a bug report either against Firefox, or Ubuntu
• Whether I should also be changing "widget.use-xdg-desktop-portal.mime-handler" and "widget.use-xdg-desktop-portal.settings", both are currently set to "2"

I've been utilizing the security protocol app DUO for work purposes for the last year with Firefox, no issues. I just recently updated to 105.0.1 and received the following error message when my DUO was prompted:

• "We're sorry, access is not allowed with Firefox due to security concerns." - with a sad face.

It then shows me a list of compatible browsers and FF being the only one not allowed to use the DUO authentication. I've attempted to clear my browsers cache, fire up FF once more only to arrive at the same messaging. I've uploaded a screenshot of what I ran into.

This has to be some sort of error as I've been utilizing FF and DUO together successfully with no issues over the last year.

Any help is greatly appreciated.

I can log into GMail via our SSO just fine, however after a few minutes I see the "error connecting for X-minutes" bar. I try to force refresh the site and every time I get the bellow error. This is also happening when I am using Firefox Troubleshooting mode, to see if maybe it's a plugin/extension causing this issue, but it's not.

Secure Connection Failed

Firefox just turns into a black screen and becomes unusable. It has been happening for a long time now and i have checked RAM and CPU usage and they are all fine, as I explored potential causes.

I will be using firefox and it just turns all black on all screens and is completely unusable. To use it again I have to force close all windows and reopen it and it works again.

This is a frequent issue that I have seen

OS version: Ubuntu 22.04.1 LTS (jammy), 64-bit (amd64, x86_64). Firefox version: 110.0 (64-bit) (NOTE: the issue was noticed with version 109.0, too)

Firefox package was installed on Ubuntu through 'APT', using the Mozilla Team repository (https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu/). It caught my attention that an excessive amount of Firefox related 'DENIED' AppArmor log messages is generated during the browser activity.

According to messages, Firefox is occasionally denied read access to '/sys/devices/' area and read/write access to 'oom_score_adj' target in '/proc/'. Could somebody clarify why would that access be required for regular browser operations? I'm a bit puzzled as I haven't noticed anything similar with the older Ubuntu and Firefox versions. A complete suppression of those messages is also an option as long as there's no negative impact on application's performance.

I already posted this question to Ubuntu forum but seems like nobody there could provide an explanation. I'd appreciate any input or hint.

Following is the sample of referred log messages:

I cannot watch a video on youtube when it is in the process of being live streamed. I remember a time when I was able to, years ago, but I can't any longer. I'm not sure what has changed. I found an article that says to install the optional update called "Windows Media Pack" in apps and features, but no app with that name exists. It was only a year old solution, so I'm unsure of what changed so significantly. I just installed another optional windows update, and also updated the browser, but still doesn't work.

Edition Windows 10 Home Version 21H2 Installed on ‎09-‎Jun-‎20 OS build 19044.1466 Experience Windows Feature Experience Pack 120.2212.3920.0

Firefox: 97.0 (64-bit)

I get so choppy scrolling that my eyes hurt after few minutes. Doesn't happen on Chrome or Edge. It is most noticable on YouTube. It feels like it's running at 15fps

Hi, I just replaced my SSD (Samsung 960EVO m.2 250Gb) for a larger/faster SSD (Samsung 980 m.2 1Tb) . I'm on Windows 10 and have 32Mb Ram. Firefox is now very slow on some websites (not all).

This example is typical and has occured on multiple sites. To test and compare, I copied the URL, created a new tab in Firefox, then Paste and Go. I timed this 3 times and each time was 30 seconds. I Pasted the same into Chrome and Edge and each time it was instant. https://savingschampion.co.uk/best-buys/personal/easy-access-accounts

On my previous SSD, there was never an issue of any lag on any site.

BBC.co.uk/news is fine, as are several other sites. Does anyone have any idea what's happening? This is making Firefox unworkable for me, so unless I can fix the issue, I will have to move permanently to Chrome or Edge. That would be a shame after many years with Firefox.

Thank you in advance.

For a few months, I have encountered an issue with videos playback on my browser. On most websites (including Reddit, Dailymotion, and even some videos on YouTube), whenever I scrub back a video, it will stop for about ten seconds, while the audio keeps playing.

My current extensions are: Metamask, Bionic Reader, uBlock Origin, Return Youtube Dislike, and TWP Translate Web Pages. I have tried using Troubleshooting mode, but the problem persisted, so I think it's not because of my extension.

My OS is Opensuse Tumbleweed, with Firefox version 155.0.3. I didn't have this issue with Firefox ESR on my previous Debian 11 installation. I hope someone can find a solution for this, as it is extremely troublesome switching to Chrome whenever I want to watch videos.

When I browse carsales.com.au and redbook.com.au I get the error message:

We want to make sure it is actually you we are dealing with and not a robot.

Please click below to access the site.

Why is this verification required? Something about your browser’s behavior has caught our attention.

There are various possible explanations for this:

   You are browsing and clicking at a speed much faster than expected of a human being.
   Something is preventing JavaScript from working on your computer.
   There is a robot on the same network (IP 180.150.36.41) as you.

I have accessed these websites many times previously without problem. Other websites appear ok.

I'm on Windows 10 pc.

Many thanks.

hello! i've been having an issue with mozilla where webp images are not loading at all. this is especially prevalent on youtube, where thumbnails simply do not load, as well as on tumblr, where if an image or gif is a webp file, it will refuse to load. both are attached in the image below to see the difference between firefox and chrome, as the images load fine on chrome. as well as that, discord, when opened with browser instead of the app, does not load profile pictures, server icons, or custom emojis. google hadn't helped me at all, and i don't know what to do at this point. i don't want to go back to using chrome.

in the attached image, the top images show a set of shark sculptures. the first does not load on mozilla, and looking at the image file, it is a webp. the second image is revealed to be a jpg, which mozilla treats normally. in the second set of images, there's a quick look at a random youtuber's page, the top being mozilla and the bottom being chrome, and you can see the mozilla thumbnails do not load.

thank you for reading! i'm very confused and am unsure what to do. any help is appreciated!

in the last day firefox has all but stopped working on most websites. i can go to them and they start to load, but then they eventually break halfway through and either end up loading forever or produce an error. if i look at the console i see "Source map error: Error: NetworkError when attempting to fetch resource." this happens on twitter.com and raidbots.com to name two off the top of my head.

i did a complete refresh and even completely uninstalled and reinstalled the browser - it started working for a bit and then broke again. i have no plugins or extensions enabled currently (i have dashlane but this happens with it enabled or disabled). it's making the browser unusable. ive scanned my computer for malware and cant find anything either. i don't have this problem in any other browsers so not sure what else to try.

I've been lead to believe in previous editions of firefox you could turn off the redirect message and instead just allow firefox to redirect.

However now (as of 112.0.1) i can't find any way to do this. I repeatedly get redirect message and i would prefer the browser just do the redirect instead of having my click a link. I know exactly where the redirect is coming from and i have no problem with it and i don't need it to have a warning.

I'm running v100.0.1 (64-bit) on Win10. I've seen others report this problem but haven't found a fix listed anywhere. <Ctrl-P> or Menu->Print results in the same problem. The print overlay starts up (say Print in top right corner), spinning wheel above Preparing Preview in the center of the overlay... Never ends. I have to Esc to get out of it. Happens on any page. Print dialogue works fine on same pages with Chrome and Edge.

Firefox began returning a PR_CONNECT_RESET_ERROR error on all websites a few days ago. Chrome likewise. MIcrosoft Edge is working fine. I am running Windows 7 with Kaspersky. I tried turning off the Windows Firewall and the Kaspersky protection, but it didn't help. I also tried disabling plugins, theme, and add-ons but it still didn't help. Any suggestions?

I have tried to disable hardware acceleration, refresh firefox, reinstall, and nothing works. It hangs every single time when searching on google or connecting to websites. This really sucks because I have used firefox since the beginning and don't want to have to stop now..

Firefox updated yestarday. I see these changes: extension are gone, theme settings were switched from Dark to Light, "Startup -> Open previous windows and tabs" option went from checked to unchecked. These things are still fine: bookmarks, saved passwords and history. Tried reverting to older Firefox version, but it didn't help so I installed the new one again. I then checked profiles in AppData folder and I see three of them. The problematic one I just described, the one that was automatically created when I tried to downgrade to previous Firefox version and the one which only contains empty "parent.lock" file. There is nothing useful in "Extensions" folders (first profile has addblock extension file which I just installed, second profile has langpack extension file). I don't particularly care about which specific extensions I used since I can just reinstall them when I need them again, but one of those extensions contained custom written scripts which were running on specific sites to help me with my work. Those scripts are what I really want to recover.

Hey there,

Intro: I recently switched to Linux and (because Brave is so broken) also to Firefox and I am liking it so far.

Problem: Unfortunately I can't copy-paste files from Ubuntu Files (Nautilus) to Firefox (I tested image files and also sounds files, neither is working).

Test with Firefox: 1. Download a random photo (e.g. from Unsplash) 2. Select the file and hit ctrl + c in Files/Nautilus 3. I go to the clipboard inspector 4. I hit ctrl + v 5. The image does not show up in the output (see screenshot)

Test with Brave: 1. Do the same as above 2. The image does show up in the output (see screenshot)

Notes: - I am using Linux Ubuntu 22.04 with Wayland - Firefox Version 107.0 (64-bit) for Ubuntu Canonical - 1.0 - I have no extensions installed - I am not using the snap version (so I can scroll smoothly) ... I think I used apt-get install but not 100% sure
