Firefox Community Forum

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.

Recent crashes ID: bp-f6b555b9-0fbb-447d-a3b3-9f7ee0240818 bp-1fad31a3-0735-49dd-92ac-44e2d0240818 bp-19ae85a5-8bd3-4d3b-b366-f65a10240818 bp-7ca6ded3-871e-45ad-8351-f21c40240818 bp-88f4aca2-437b-45d1-8d7a-11a7c0240818 bp-ebb8ed44-af42-44c1-89f9-54b1f0240818 bp-3aa6e40e-467c-4c72-8373-b23e30240818

Hello,

I'm experiencing an issue with the search bar on the Firefox homepage. When I click into the search field and begin typing, the cursor jumps to the address bar, and the text I’m entering gets redirected there instead of staying in the search bar.

I've checked my search settings, and everything seems to be in order. I’ve also tried disabling add-ons, but the issue persists. Could you please assist me in resolving this problem?

Thank you for your help.

Best regards, Tivadar Tot

I created a few virtual hosts and sites on my local machine and this is working perfectly.

Problem is with Firefox, when I enter non-existant url in address bar, Firefox force me to search and don't let me to open the url, but I need to go to this url for testing, developing, etc...

Any solution?

Any advice returned by Google seems to be obsolete or only worked perhaps in older versions of Firefox. The main idea of using userChrome.css to override the default styles for Reader View does not seem to work. My userChrome.css file does work on other items though (like removing the sidebar width restriction).

Whatever advice I find via Google perhaps cites outdated CSS selectors, but current selectors do not seem to be documented anywhere by Mozilla. Moreover, I cannot find any file on my local drive named aboutReader.css when using find or grep commands in bash, those this file name is alluded to when viewing a page in Reader View and then in turn viewing source on that transformed page.

Moreover, addons that would allow me to change the colors seem to be restricted in Reader View.

It does seem like something has changed in recent Firefox updates but I can't remember when I last saw, for instance, links in dark mode Reader View that were still pink (whereas now they are blue, and impossibly dark to see, especially when you are disabling as much blue light as possible through your operating system). I need a higher contrast color for links in dark mode Reader View so I can actually see them.

I can alternatively use the Tranquility Reader addon and have custom colors, but A) that addon does not work with the Automatic Reader View addon, whereby I can always have various sites appear in some sort of "reader view" whether the native one or Tranquility Reader, and B) hitting refresh when in Reader View will defeat some soft paywalls but this does not work with, e.g., Tranquility Reader, so I still would prefer to be able to custom colors in the native Reader View feature, rather than rely on an addon.

1. Where are the current styles for Reader View even documented? 2. Is overriding them now restricted? 3. Why did the link color change from pink to blue in newer versions of Firefox (this is a terrible accessibility bug)? 4 .Where is the alluded to aboutReader.css stylesheet actually stored on my computer (it doesn't seem to be a file on the filesystem in the Firefox profiles folder, it seems more like it is embedded in the Firefox binary/executable)? 5. Will Firefox settings ever allow us to set colors specifically for Reader View (I don't mean the override settings for all web pages, particularly web pages not being rendered in Reader View ... that setting does not help in Reader View, nor would it be the desired preference for pages not in Reader View)?

Thank you.

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.

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?

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.

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.

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.

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().

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?

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 :)

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, 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.

Twitch, Youtube Live, Netflix, Kick... it seems any live streaming platform cannot play. I am running Linux Mint 21.3, Kernel 5.15.0. They work on a different browsers, they all also work on Firefox my laptop, which is also on the same OS and Kernel.

I have tried everything: installed ffmpeg, installed unrestricted ubuntu codecs, refreshed firefox (twice), uninstalled/reinstalled firefox, ive tried without extensions, yet nothing.

Cant for the life of me figure it out, im not sure if its my PC or Firefox on this machine.

Hi, after upgrade of ubuntu to 24.04 i got into problems with using Firefox. I it running on x11 with proprietary nvidia driver, no matter of source package (snap or deb from the Firefox repository) and no matter of safe mode the Firefox gets frozen when clicking into any dropdown control in side page, the same happens when trying to open bookmark folder in the bookmarks panel or even the dialog that opens from the star icon in address folder that should add page into the bookmarks. When running on command line, in case of the snap version there are just some warnings of some missing css file, in case of the deb version it does not output anything suspicious. I was even trying to change the UI theme (qt) as well as GTK theme in case it makes any difference, but it did not... Thanks for any help.

This issue is happening with every newly installed add-on, but not with add-ons installed on or before Aug 3, 2024. The add-ons are installed via addons.mozilla.org. To rule out the possibility that it's happening only with specific add-ons, I also installed one of the random recommendations on that page, Augmented Steam which has 54,248 users, and it happens with that one as well.

I'll click Enable, but the prompt appears every time I restart Firefox.

What I've tried (with a restart after each attempt):

• Clear the startup cache
• Delete extensions.json
• Delete compatibility.ini
• Via about:config deleted extensions.databaseSchema and extensions.getAddons.databaseSchema
• Excluded Add-ons from syncing

I've noticed the following in extensions.json for each of the recent add-ons after restart:

• syncGUID changes to presumably random new value
• active changes from true to false
• userDisabled changes from false to true
• seen changes from true to false
