Firefox Support Forum

Hello,

I've spent several hours today trying to fix FireFox slow start up on my system. After start up (about 2 full minutes), everything works normally. The hardware is an ASUS A88xm-A MB, A10-6800K processor, 16G DDR3, runs OS and programs off an SSD. I worked through all the slow startup suggestions, ran memtest (0 Errors, 1 Pass), disabled all add ons, (even the OpenH264 video codec (I use the onboard HDMI, no graphics card)), turned off hardware acceleration, etc. When starting in troubleshoot mode, less than 30 seconds, (acceptable), but I really don't know where to begin with the "More Troubleshooting Information" when I look at the table generated by it. There have been no other problems to date with the system, and the long start-up time began with 20.04 Ubuntu (about a minute), then got worse when I upgraded to 22.04 to try to solve THAT problem. Currently running FF 104.0, and the update page says wait for a distro update if that is how it was installed. I believe 104.0 is the latest Linux 64b version though. All updates to the system are done as soon as I'm notified of them. there have been none since the upgrade a few days ago.

Any suggestions? Gotta get some sleep now... TIA, Dave

The main youtube page loads and displays ok. As soon as a video is played (even in preview), firefox crashes. I'm on Linux Manjaro. other websites with video work fine (for ex Vimeo) I tried disabling all my addons and plugins in the normal mode (not troubleshoot mode) and it still crashes. However, the troubleshoot mode works fine ! Refreshing firefox didn't fix the issue. I have another computer with Linux manjaro and firefox works just fine. I spent a lot of time trying to understand what's wrong but I really don't see why.

Thanks in advance for your help.

Firefox worked perfectly, but since a few days I can't download anything. I'm using Mozilla Firefox snap for Ubuntu 22.04, version 110.0.1 (64 bits) canonical-002 - 1.0 With Chrome everything works perfectly so I assume it's a problem from Firefox.

When I open a PDF, a MP3 or any file, the "save" option doesn't display anything. Usually it opened a dialog where I could choose the folder where I wanted to download the file, but now I have nothing.

I have only 4 extensions: - adblocker ultimate - duckduckgo privacy essentials - vuejs dev tools - zotero connector

I always had them and I never encountered any problem.

I'm running Firefox 99.0.1 on Ubuntu 22.04. Recently (I think since I updated to Ubuntu 22.04 about a week ago), Firefox has been refusing to show me file upload dialogs. When I click a button that's supposed to give me one, nothing happens.

This has been happening with: - The "attach files" button in Gmail - A file upload button on Gradescope (website for managing homework assignments) - File -> Open File... and Ctrl+O.

Dragging and dropping a file onto an email in Gmail does attach the file -- it's just that the button doesn't work.

I've tried restarting, and I've tried running Firefox in Troubleshoot Mode -- so far nothing has fixed the problem. What else should I do?

I have disabled DRM content, why is firefox annoying me to enable it each time I load a website that requires it. What seems to be now the general topic, even for a simple blog... If I disabled it, I do not want to be prompted to enable it back. I know how to enable it.

Whenever I attempt to access DRM content such as netflix or spotify I am notified that the WidevineCdm plugin has crashed. I'm running firefox version 101.0.1 on Kubuntu 22.04, I am running the debian package release, but I had this issue with the snap version too. I've submitted crash reports, but they're all "EMPTY: no crashing thread" (https://crash-stats.mozilla.org/report/index/20af09a5-6bc4-4719-9242-38f5c0220614 here's one).

I upgraded to Ubuntu 22.04 recently. Since then Firefox 104.0.2 (64-bit) has been arbitrarily freezing; sometimes i have to restart the computer while most of the times I am able to kill the Firefox main process and restart Firefox.

The freeze occurs when i try to save a Web page; i don't see any "logic" as to which Web pages cause Firefox to freeze. It seems totally arbitrary.

I clear my downloads list everyday (sometimes more frequently than that) and clear cookies & cache everyday.

I have selected "no proxy" by default, in 'Connection Settings'.

This never happened until after i upgraded to Ubuntu 22.04.

I've browsed the support pages and don't find anything relevant to my problem. If I'm overlooking something, I apologize in advance!

I have attached a 'screen capture' image of Firefox processes just before i killed the main process.

Thanks in advance for any suggestions. Ramki

Everything under Logins and Passwords, and Forms and Autofill is unchecked. A "Primary Password" has never been set in firefox.

Can't get it to stop asking, which is made worse by the fact that nothing is selected to prompt it nor is anything stored for it to use.

I'm using Firefox in Ubuntu 22.04.2. I recently update to 112.0, then 112.0.1

With both versions, the scroll bar is not available on some sites which used to work in previous versions. Items which are outside the initial viewing area are not visible.

Is anyone else affected by this issue?

Sync is a nightmare. It is so unintuitive! What exactly would be wrong with having separate Export and Import buttons for each of Settings, Addons, Tabs, History, Bookmarks, etc? I have a desktop box and a newer laptop I wanted to get up to date. I pressed the Sync button on the desktop ... By the way, there`s a link below that reads "Connect another device" ... Connect where? Someone is designing these interfaces who has absolutely zero imagination. Anyways, I signed off, moved the ethernet cable to my laptop, signed in, pressed Sync, and voila!, I got my Bookmarks, at least. But I have no idea how to get my tabs and windows. I tried with a "download link" something or other, but it seemed to assume I was sync-ing to a phone, and didn`t work. Any way to get my tabs?

Firefox seems to have a problem on Linux using USB Security Keys. I have two Yubico Security Keys which I use for 2FA. The problem seems to be that Firefox cannot communicate with the USB port, as it doesn't make any difference whether the USB Security Key is plugged in or not, the error returned is always the same and the Security Key does not light up.

I believe Firefox's WebAuth code must be fine, as it works on Windows, which is why I think it's some kind of permissions problem. Chrome works perfectly with the Security Keys on my computer.

I've used a number of sites (I've listed a couple below) where you can test your Security Key with Firefox on KDE Neon and the error is always "UnknownError: The operation failed for an unknown transient reason":

https://www.token2.com/tools/fido2-test/ https://demo.yubico.com/webauthn-technical/registration

I cannot log into Bugzilla with GitHub as my GitHub login uses a Security Key as the second factor.

I forgot my password to my Firefox account, and only just realized I haven't updated it in KeypassXC when I was trying to log in to a new machine. It seems that, even though I am already logged in on my old computer and have full access to my account (including saved passwords, bookmarks, and browsing history) I can't find a way to reset my password without deleting all of my synced data. From the "Change Password" menu, it requires my old password if I want to change it without deleting everything. Also, I have 2FA enabled, so why isn't there the option to authenticate my identity in a password reset using 2FA instead of my old password? I know a similar thing already exists for recovery keys, but I only have 2FA. Is there any way for me to reset my password where I don't lose everything? Thank you.

I am attempting to import server certificates into Firefox. But the "Import" button does nothing when viewing certificates. Any work around? I need to import our server certificates into the Authorities section.

Ubuntu 22.04 Firefox installed through snap. Version 104.0 just upgraded this afternoon.

Thank you, James

I am using firefox v104 on linux mint. This problem happened this evening. Every tab i open shows the same error.

I tried the solutions suggested in other similar forum posts like >safemode (tabs still crashed) >driver update (my drivers are up to date as far i can tell) >deleting cache and reinstalling firefox (tabs crash). I took a backup of my bookmarks and extensions as suggeated in another forum post. > one youtube video (https://youtu.be/F9VaXwSB_po) suggested toggling media.cubeb.sandbox in the config section. The tabs started loading after that but it wasnt that useful as i wasnt able to get any videos to play in the browser.

Also, i don't really know if the issue is related, but chrome tabs were also not loading or responding ('Page unresponsive' error).

Please help. Thank you :)

Hello all,

For some reason, I can no longer upload or download files, with the pop-up window failing to appear entirely. I can upload folders through, for example, Dropbox or Google Drive, but individual files don't work.

I've reset my browser, uninstalled and reinstalled it, opened it in troubleshooting mode, disabled enhanced tracking protection, but nothing seemed to work. I've tested another browser, and I was able to upload and download files just fine.

Is there anything I can do to fix this? I'm on Ubuntu 22.04 using Firefox 107.0.1.

I work on kubuntu 20.04 with plasma 5.18.8 desktop environment. I have a QtCurve-based custom application style, which I almost match with css for GTK apps. Firefox has to be an exception by itself! Not only that, but it changes my ability to customize its interface, from time to time and even changes access to such ability, on some updates.

My scrollbar customizations in userChrome.css and userContent.css do not work any more (other CSS changes still work, for menu/addressbar/tabbar/bookmarksbar orderint and tab styling). I had to resort to settings in user.js file, to get a 20px width scrollbar, suitable for my big screen, but... it gets very wide when I increase the focus, on some webpages and becomes very ugly! Furthermore, I cannot make sense of the proper use of "ui.themedScrollbar*" settings and the scrollbar and its slider result in the same color. These are my settings in user.js:

user_pref("widget.content.gtk-theme-override", "backwater"); user_pref("widget.non-native-theme.enabled", false); // Use GTK-3.0 gtk.css: set to false user_pref("toolkit.legacyUserProfileCustomizations.stylesheets", true); // Use userChrome.css & userContent.css: set to true user_pref("widget.gtk.alt-theme.scrollbar_active", true); user_pref("widget.non-native-theme.scrollbar.size.override", 20); // If nothing else works, fix scrollbar width to 20px user_pref("widget.non-native-theme.gtk.scrollbar.round-thumb", false); user_pref("widget.non-native-theme.gtk.scrollbar.thumb-size", 1.0); // originally 0.75 user_pref("widget.non-native-theme.gtk.scrollbar.allow-buttons", true); // it was true, anyway... user_pref("layout.css.cached-scrollbar-styles.enabled", false); user_pref("layout.css.color-mix.enabled", true); user_pref("widget.non-native-theme.scrollbar.style", 4); // wide scrollbar theme: set to 4 user_pref("ui.themedScrollbar", "#bad1f5"); user_pref("ui.themedScrollbarInactive", "#668cc4"); user_pref("ui.themedScrollbarThumb", "#e4e4e4"); user_pref("ui.themedScrollbarThumbHover", "#e4e4e4"); user_pref("ui.themedScrollbarThumbActive", "#668cc4"); user_pref("ui.themedScrollbarThumbInactive", "#bad1f5"); user_pref("browser.dom.window.dump.enabled", false); user_pref("extensions.ui.sitepermission.hidden", false); user_pref("fission.experiment.max-origins.qualified", true);

Either with the "ui.themedScrollbar*" settings or without them (and cleared from the prefs.js file), the scrollbar and its slider result in the same color, unless I (tryingly) click on some place on the scrollbar outside its slider; then I can see the slider, _only_ for the duration of the mouse-down event (which causes up or down page-hight scrolling).

The default, very thin scrollbar, as well as my modified wide scrollbar with invisible slider are both useless to me! I have even tried fx-autoconfig (https://github.com/MrOtherGuy/fx-autoconfig) to make the scrollbar CSS work, but no result. At this point, I am considering switching to another browser, despite the trust I have to mozilla, for my data and privacy.

2FA login on sites works with Chromium but NOT WITH Firefox (Linux)

Present setup:

Does NOT work firefox 102.7.0esr on debian 11.6 bullseye 5.10.162-1 (x86-64) firefox 110.0 on Ubuntu MATE 22.04 LTS 5.15.0-58 (x86-64)

Works chromium 109.0.5414.119 on debian 11.6 bullseye 5.10.162-1 (x86-64)

I am able to register and authenticate with security devices Yubikey NEO (without FIDO2) and Yubikey 5 NFC (FIDO2 compliant) on several sites (eg. pypi, google..) using Chrome or Chromium but now not with Firefox at all. It has not worked for at least the last few updates. Changing settings in about:config or plugging/unplugging keys, stopping every Firefox plugin etc. don't help. Neither does a fresh Firefox install without any super-security-settings.

Testing sites like Yubico's own or Okta's works fine using Chromium but not Firefox.

From what I can see this is not especially related to FIDO2 (Webauthn). pypi seems to use U2F which should work just fine with Firefox since way back.

I haven't tested Firefox for Windows but Chrome browser for Windows 10 works fine (which I tested first when Firefox didn't cut the mustard), I therefore expect it to work also on Chrome browser for Linux. Just to check if this was related to a debian bullseye package, I tested it on Ubuntu MATE too, which didn't do the trick. Haven't done any more testing than that on MATE.

This seems like a strictly firefox problem. -What to do?

As per this issue I reported a while back, I was experiencing odd issue with automatic redirect to HTTPS for some private development sites.

I finally found a fix for the issue. The problem appears to be with DuckDuckGo Privacy Essentials Extension which apparently *may automatically redirect to the http site. In order to prevent this, I added my development sites to 'Unprotected Sites' and this prevented DuckDuckGo from doing the automatic redirect to https.

• - Odd thing is that I had multiple domains pointing to the same web instance and only one of the domains was having this issue with the DDG extension. Both were going to the same IP through a HTTP proxy. The proxy and web server were not the issue. This symptom points to an maybe an issue in Firefox....

In summary, be wary of odd redirects and the DuckDuckGo Privacy Essentials extension if you are doing web development work.

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.
