Diễn đàn hỗ trợ Firefox

I have been using Linux Mint 21+ since May of 2023. At that time I set all the Firefox preferences settings to what I've always set them to in the past, and have run Firefox with them ever since then. Now, about 3-4 weeks ago, I started Firefox and it came up with ONLY blue lines of text (not graphically). My Firefox homepage is "isp.netscape.com". I've waited until now to report the problem, since I was hoping that later Firefox updates would fix itself, but this did not occur with the 3-5 Firefox recent updates.

Originally, I posted the problem to the Linux Mint forums with the following title under SOFTWARE & APPLICATIONS: Firefox browser no longer graphical but only lines of blue text

Somebody there advised me to start Firefox in safe mode, which I did with this command in the terminal: firefox -safe-mode

and to my surprise, Firefox then came up graphically once again. However, going through the Firefox preferences and setting them one at a time, I came to what is causing the problem. Setting PRIVACY & SECURITY -> BROWSER PRIVACY -> HISTORY: "Remember History" to "Never Remember History" forces Firefox to reboot and when it comes up it came up with only blue lines of text, and not graphically.

One responder to my post on Linux Mint forums stated that it was also a problem with her on Windows 11. So, this is not a Linux Mint, or Windows 11 issue, but a Firefox issue. Mozilla made some change to Firefox back 4-5 weeks now that all of a sudden made Firefox come up in blue lines of text, and I changed nothing with Firefox since started with Linux Mint 21.3 1.5 years ago. I will add though, that ONLY my Firefox homepage (listed above) is the only page that is affected by this, every other website I visit comes up graphically.

What's UP?

Hello everyone,

I recently reinstalled my Linux system, Parrot OS, which comes with Mozilla Firefox. Unfortunately, I forgot my Firefox password, which forced me to reset it to log in.

Since this reset, Firefox no longer loads my bookmarks, extensions, or saved accounts.

Does anyone have suggestions for recovering this data? Is there a way to find my old profiles or backup files?

Thank you in advance for your help!

For the past few months, the browser will no longer download any files. The only diagnostic that I can see is failed when the download is attempted. I have refreshed firefox and the problem remains. Chrome can download without any problems, but I used firefox for many years and wish to continue.

Machine: Dell Inspiron 15 5567 CPU: Intel i5-7xxx Op Sys: Ubuntu 24.04.1 Firefox version: Flathub 130.0

For the past 2 weeks Firefox has been repeatedly crashing soon after going on to certain sites or trying to apply my 2FA authenticator add-on.

Suddenly there's a screen shudder and a new window opens, inviting me to submit a crash report. See attached image.

I do not believe that this is down to Ubuntu 24.04 upgrade done at end of August.

But it's enough for me to largely go over to Chromium and Firefox Dev Ed.

If Mozilla don't act on this crashing I can see its market being lost fairly fast.

Hello,

After a few days I noticed that the option "open with" on the downloads dialog is always grayed out (see the attached picture).

If I go on the settings and tell the browser to not ask and open directly the file, it opens without any problem... (actually it shows an advertisement saying it is an executable file, but when I dismiss it, it opens)

Here are my system setup: Nom: Firefox Version: 130.0.1 Identifiant de compilation: 20240913135723 ID de distribution: mozilla-deb Canal de mise à jour: release Agent utilisateur: Mozilla/5.0 (X11; Linux x86_64; rv:130.0) Gecko/20100101 Firefox/130.0 Système d’exploitation: Linux 6.1.0-25-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.106-3 (2024-08-26) Thème du système d’exploitation: Breeze / Adwaita Binaire de l’application: /usr/lib/firefox/firefox-bin

Does anybody else is having this issue? Any ideas on how can I fix it?

Thanks in advance for all your help,

Best regards, Marc

EDIT: I just tested the behavior on the "base" Firefox-ESR, and it works as expected, as you can see on the 2nd attached file, esr.png... Version: 28.2.0esr Identifiant de compilation: 20240826114743 ID de distribution: mozilla-deb Canal de mise à jour: esr

I am running Lubuntu 22.04LTS (have been for months now), with Firefox 130.0.1 installed via the normal vanilla apt.

It was working fine until a few days ago (perhaps after an update, but I can't recall specifically), and then just stopped being able to save anything.

For example, right clicking on an image will bring up "Save As..." as an option, but when I choose that, nothing happens. No prompt to save, nor does the file appear anywhere.

When I choose "Save" as a pulldown on cloud XLSX files...similarly, nothing happens.

When I download something, Firefox is supposed to open up a prompt asking me where I want to save the file but that never opens...nor does the file download.

I am totally baffled.

This video file cannot be played.(Error Code: 102630). - This is the error i get when i try to play this movie .

Context : - I upgraded to the latest version of firefox and i also connected my dns to nextdns recently. - I use arch linux and firefox on linux. - Previously all the videos on the site were playing nicely but now it has started showing this error. - I have tried many solutions such as :- 1. Clearing cookies, cache,etc and refreshing firefox . 2. Installing media codecs onto my pc using console. 3. Deactivating the dns and disabling hardware acceleration. 4. Restarting my pc but nothing works.

I was wondering if someone has a solution to this.

So, There's this website called pw.live and I use it for study purposes. And I've recently switched to linux and installed firefox. But that website loads but any videos or live streams don't. Even though it works perfectly fine on Windows version of firefox.

I tried to search about this and it may be because the content is DRM protected. I'm just speculating though it may be broken for some very different reason. I also looked into solutions to fix DRM related issues. And found some solutions but the plugin Widevine Content Decryption Module provided by Google Inc. just doesn't exist in the plugins tab. There is only "OpenH264 Video Codec" there. And I think that might be the problem.

Thanks in advance.

Hello guys, as in title - I use custom NextDNS set of rules on DNS-over-HTTPS. As of today, Firefox can't connect to the provider. AFAIK Troubleshoot Mode is also affected. The other devices using NextDNS on my network work just fine and when I set the DNS to work system-wide as a kind of workaround, I don't get an issue. Same when I use other DNS-over-HTTPS options in the Firefox Preferences. Yesterday the problem didn't occur and I haven't performed any updates since yesterday - both Firefox and NetworkManager seem to be up to date.

Additional info: OS: EndeavourOS (Arch Linux) Firefox version: 129.0.2

If any other info is needed, I'll be happy to provide it to you.

I seem to have a problem with Firefox's builtin PDF viewer. Instead of black text on a white or gray background or something else sensible, I get black text floating over my desktop background in the part of the Firefox window that's showing a PDF. PDFs display fine in an external viewer, but that's just passing the buck, isn't it? Is there a way to fix this on Firefox?

I suspect hardware acceleration is the issue, but everything else seems fine, so I don't want to just blanket disable hardware acceleration. How can acceleration for PDFs alone be disabled?

Hello guys,

The trouble I ll present you might come a bit late, I've just never thought about asking on this forum (didn't even know that it exists lol) and I spent a lot time on tutorials trying to find the solution... lol 😩

My situation : I have a laptop with debian 12 stable. Early July, I updated my apps, Firefox 128 has just been released. Since the Firefox 128 update, I can no longer execute Firefox, I always get the pop up message :

Failed to execute child process (no such file or directory)

I've tried many times to uninstall & reinstall, purge & reinstall. Still the same "failed to execute... " message. all the subsequent updates (128.X and 129.X) haven't solved this problem...

On the other hand, Firefox ESR 128 works like a charm.

Is anyone in the same situation as me ? 😕

Wishing you a nice day :)

Hi!

I've been browsing the web looking for a way to access the browser's current profile name programmatically. I'm writing a little browser extension that should run code conditionally depending on what the current profile is. I'm wondering if there's any way to do this? The closest thing I found was runtime.getBrowserInfo() runtime.getBrowserInfo().

I've installed firefox with pacman on Linux, and I installed arkenfox. It did not work, I tried other user.js', none worked. I've also tried wiping my entire firefox root folder, then using arkenfox, but did not work.

Firefox is adding empty lines to the css file in web developer like so:

1. videoFiles {

 left: 0;
 z-index: 3;
 width: 250px;
 height: 40px;
 opacity: 0;
 cursor: pointer;

}

1. image_files {

 height: 40px;
 width: 250px;
 z-index: 3;
 opacity: 0;
 cursor: pointer;

}

.previewVid {

 width: 50%;
 padding: 10px;

}

Those empty lines are not in the css file and so it is reporting the wrong line numbers. So hard to find the correct line in the actual file.

Up until a few weeks ago, I could see and access Mobile Bookmarks (I sync these to my Firefox Desktop) using the Firefox Desktop browser from the Bookmarks drop-down menu in the topmost toolbar.

Now, I can no longer find Mobile Bookmarks in the Bookmarks drop-down menu.

I can still find it by choosing Manage Bookmarks and, in the resulting pop-up, I can see it in its regular location there. However, this is significantly less convenient as it requires me to juggle another window and perform more clicks.

Is it missing due to a bug? Does Mozilla intend to fix/address this?

Thank you in advance for any help.

When I copy something to my clipboard I can paste it into Firefox. Into web pages and also into the URL bar.

But when I copy something in Firefox, it does not go to the clipboard. The clipboard still hast the content which was already there.

Also strange: When I cut text in a textarea, input element or the URL bar, the text is removed. But it is not sent to the clipboard. When I cut and paste, the text I get is what was previously in the clipboard.

What could be the cause? How can I debug this problem?

As I said in the title, the spellchecker add-on I use, LanguageTool, does not work on this site. I am not fine with that. What's the best way to get it working here? Any answers that amount to "you don't" are not acceptable.

Hi. I got a new laptop some weeks ago (Linux Fedora) and I've been using Firefox without any problems until last week. When watching Youtube videos my system shell crashes completely. This problem ONLY happens with Youtube videos and Firefox. Other browsers work fine and I don't have this problem in other websites.
