Firefox supportforum

Hello,

I am using firefox 126.0 on linux mint 21.2 with an policy file in the directory "/usr/lib/firefox/distribution/policies.json". This is just working fine with one little problem. When opening firefox the first time, it does not apply the policy to set the startpage to the url in the policy file. All other policies seem to be applied correctly. I figured out, that at the first start of firefox, no user profile (folder) "~/.mozilla/" exists. When i click the little "house" button on the the top besides the refresh buton, the correct startpage is shown. After the first start this folder is created and then the policies work fine even the startpage shows up directly. Can I somehow use a template profiles-folder for new users, so they have the correct firefox feeling at the first start or is there something missing in my policy file ? The policy file has rights set to "644 root:root" Image of the policy file is attached because I can't upload files other then images.

Thank you.

I am running Firefox 126.0-1 on an Arch Linux system. Most websites are failing to connect for security reasons.

Some sites, including google.com and nytimes.com, fail with an "SEC_ERROR_UNKNOWN_ISSUER" error, and their certificates confirm that they are respectively issued by Google Trust Services LLC and DigiCert Inc.

The website archlinux.org errors with "MOZILLA_PKIX_ERROR_MITM_DETECTED", stating that "Software is Preventing Firefox From Safely Connecting to This Site", citing in particular ISRG Root X1 as the problem. The certificate confirms that it is issued by Let's Encrypt.

The website duckduckgo.com simply errors with "SEC_ERROR_PATH_LEN_CONSTRAINT_INVALID" and states "Secure Connection Failed"

I have confirmed in preferences that my proxy settings are set to "No proxy" and the problem persists across troubleshooting mode and making a new profile. I have also tried removing the cert9.db file in a given profile folder.

I'm switching to Firefox from Vivaldi since adblocking on YouTube no longer works on Chromium-based browsers, and Google is determined to annoy me even outside of Chrome (they also forced their material design context menus on everything else based on Chromium). However, I'm finding I'm missing the reading list functionality immediately. It has become a basic part of how I browse, and I attempted to use Pocket, but I'm finding that I hate how Pocket works compared to Vivaldi's reading list. Does anyone know of a good extension that emulates how Chromium-based browsers have their reading list, including working with sync so I can pass links between devices?

Sometimes a box pops up on the screen that asks if I want to block or allow something. Sometimes I have no interest in doing either, and just want the damned dialog out of my face. The page seems to work otherwise, but the stupid browser keeps the dialog over top of things, and clicking outside of it, and hitting Esc, don't make it go away. I think those actions used to work, and I think there, sensibly, used to be a dismiss option, but that seems to be absent now. There's no sense to trying to force me to make a decision I don't want to make, and doesn't even need to be made, and I want this thing to cut it out.

Hello when i am on facebook,and i want to do a video chat or a call chat it now tells me that video or voice calling is not supported by this browser,yet it was all working fine about a week ago and i went to do a video call two days ago and now i can't,i have no idea what has happened regards mark

I am trying to configure Firefox on macOS to not prompt the user to make it the default browser.

I am using the following script to create the profile and set the user preferences after installing Firefox by copying `Firefox.app` from the downloaded DMG: ```

1. !/bin/sh

open -a Firefox.app --args -CreateProfile default sleep 1

write_userpref() { USER=$(whoami) PROFILE=$(ls -1 "/Users/${USER}/Library/Application Support/Firefox/Profiles/" | grep -E "\.default$") cat << EOF > "/Users/${USER}/Library/Application Support/Firefox/Profiles/${PROFILE}/user.js" // mandatory comment? user_pref("app.update.auto", false); user_pref("app.update.disable_button.showUpdateHistory", false); user_pref("app.update.enabled", false); user_pref("breakpad.reportURL", ""); user_pref("browser.newtabpage.activity-stream.feeds.topsites", false); user_pref("browser.newtabpage.activity-stream.feeds.section.topstories", false); user_pref("browser.tabs.crashReporting.sendReport", false); user_pref("browser.discovery.enabled", false); user_pref("browser.defaultbrowser.notificationbar", false); user_pref("browser.shell.checkDefaultBrowser", false); user_pref("browser.shell.didSkipDefaultBrowserCheckOnFirstRun", false); user_pref("browser.shell.skipDefaultBrowserCheckOnFirstRun", true); user_pref("browser.newtabpage.enabled", false); user_pref("experiments.enabled", false); user_pref("extensions.pocket.enabled", false); user_pref("toolkit.telemetry.enabled", false); user_pref("update_notifications.enabled", false); EOF }

write_userpref

open -a Firefox.app --args -new-tab -P default "about:blank" sleep 3 osascript -e 'quit app "Firefox"' sleep 2

open -a Firefox.app --args -P default about:blank ```

Here's the behaviour I'm seeing:

1. Firefox starts to an `about:blank` tab, however there is a second "Firefox Privacy Notice" tab
2. AppleScript quits Firefox
3. Firefox starts to an `about:blank` tab, however it is now prompting me to make it the default browser

I do not want Firefox to prompt the user to become the default browser.

My ideal scenario is that Firefox starts without the "Firefox Privacy Notice" tab and without prompting me to make it the default browser. From the observed behaviour, this doesn't seem possible.

Can anyone tell me how I can accomplish this without user interaction or MDM?

I want to disable this redundant dropdown there is a post here from 6 years, but dont dolve my problem, I dont want to disable or separate the seach and the url bar, i just want to get ridoof this redundant information, just for curiosity, if i disable search or separate the bars, i still get the anoing dropdown but with "Visit" instead of "Seach with"

I need to go over the head of the Mozilla Triage manager who has left https://bugzilla.mozilla.org/show_bug.cgi?id=1406865 open without a resolution for **seven years**. How do I do that? This is a bug reported in Firefox 57 and **still** not fixed in Firefox 125. I cannot find any support category anywhere in the Mozilla website that covers appealing a decision by one of their employees. The last comment from this uncooperative indivisual is "But given we support it on macOS and Windows yeah, it seems not very objectionable." Who is this **clerk** to override the fact that a number of customers very much find this "objectionable". I cannot find anything on https://www.mozilla.org/en-US/contact/ that addresses this issue. I cannot find even a surface mail address for Mozilla. For example my complaint has nothing to do with any of the following:

   I’m having problems with using Firefox
   I want to donate to Mozilla
   I have questions about using Mozilla’s trademarks
   I’d like to report misuse of a Mozilla trademark
   I want to hold an event in a Mozilla space
   I want Mozilla to sponsor my event
   I’d like permission to use a Mozilla logo
   I’m interested in Pocket’s sponsored content on Firefox
   I’m a member of the Press and have a question for Mozilla

Yes I am having a problem with Firefox, but the clerk responsible has, through sitting on this issue for **seven years**, basically told the entire community that he doesn't give a reservoir.

In particular I feel this unacceptable behaviour should be brought to the attention of senior management, but there are no contacts for anybody in senior management.

Currently, when I try and open downloaded .txt files and .log files (that is, when I click on them directly from the download pop-up that appears at the top-right of the browser), Firefox inexplicably opens Aegisub on my machine as the app to use. This is in contrast to when I open it directly from within my file browser, where it opens the Kate text editor, as suggested by the default app option in the permissions of the filetype.

How do I change the apps Firefox uses to open downloaded files? I've tried going into my settings and looking at applications, but .txt and .log don't appear, so I'm not quite sure what to do.

I'm on Kubuntu 22.04.3 LTS, using the Firefox deb package.

I am trying to use a <select> tag to display a color selector. So each <option> has a background color to match its displayed text:

```<select id="strokeColor" name="strokeColor" style="width: 10em;">

             <option value="black" style="background: #000000; text: #FFFFFF">
                     black
             </option>

<option value="aqua" style="background: #00FFFF">

                     aqua
             </option>

<option value="blue" style="background: #0000FF">

                     blue
             </option>

<option value="brown" style="background: #A52A2A">

                     brown
             </option>

<option value="gray" style="background: #808080">

                     gray
             </option>

<option value="green" style="background: #00FF00">

                     green
             </option>

<option value="magenta" style="background: #FF00FF">

                     magenta
             </option>

<option value="orange" style="background: #FFA500">

                     orange
             </option>

<option value="purple" style="background: #800080">

                     purple
             </option>

<option value="red" style="background: #FF0000">

                     red
             </option>

<option value="white" style="background: #FFFFFF">

                     white
             </option>

<option value="yellow" style="background: #FFFF00">

                     yellow
             </option>

<option value="#000000" selected="" style="background: #000000">

                     #000000
             </option>
         </select>```

On Chrome this displays as expected:

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2024-04-18-22-02-25-eebbd5.png

But on Firefox the background colors are ignored:

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2024-04-18-22-02-35-bd90ee.png

How can I get Firefox to display the background colors?

I always keep two Youtube tabs open at all times on my computer. After a while of running, however, the site starts to get increasingly laggy, in a way that simply reloading the tab does not fix. (I am aware that this is likely a result of one of the extensions I have installed that affects Youtube's behavior, specifically SponsorBlock and Return Youtube Dislike, but I am not willing to uninstall these.) I also know of a "force reload" - pressing ctrl + shift + R instead of just ctrl + R in order to clear the cache or something.

However, whenever Youtube starts getting really slow, I instead like to do something I call "crashing the tab" - I open my system monitor, look for the current most CPU-intensive "Isolated Web Co" process, and end it. This pops up an error message in Firefox that says "Gah - your tab just crashed!" and offering me the option to restore it. After restoring it from this window, the performance is back to normal.

My question is, is this beneficial, or is it functionally identical to a normal force-reload? Is the improvement I see between this method and force-reloading the page just placebo? And if not, is there a simpler way to do it without opening a second program?

Hello, I administer a small fleet of Ubuntu desktops. For a variety of reasons we avoid using Canonical's Snap package version of Firefox.

Currently the fleet is using Firefox installed from the Mozilla Team PPA repo. However that repo can be incredibly slow and after reading about the new Firefox deb packages [1] from the Mozilla APT repository we would like to move to them. The problem is that these packages lack Apparmor profiles, so unfortunately my security team won't let me use them.

Would it be possible to add Apparmor profiles to these packages please? They would need to be applied only when an OS has Apparmor enabled, which may not be the default for Debian.

Thank you!

I using kubuntu (ubuntu with kde) 22.04 and firefox will not recognize my security key. There is a really good thread on this here. It is now closed.

https://support.mozilla.org/en-US/questions/1412073

One of the solutions is to install firefox from the mozilla server. On other forums, this is referred to removing snap and installing the debs. I haven't tried this.

Reading through the thread however, it seems like the snap version should work. The manufacurers id and product code for my Thetis FIDO2 usb key are present in the etc/udev/rules.d/70-snap.firefox.rules

This answer says to disable apparmor. I tried that, but it didn't work.

I have quoted this answer below.

This isn't actually a firefox problem. KDE Neon uses the firefox package from the Mozilla Team PPA and there's nothing wrong with that package. The problem is that Neon enables app armor on firefox which breaks access to password managers and security keys. sudo aa-disable usr.bin.firefox works around the problem by disabling app armor for firefox. aa-complain was not sufficient in this case.

Is there anything else I can try?

Hi, I'm using Firefox 125.0.3 64-bit with Linux mint and some of the tiles on the homepage have disappeared I have selected 4 rows in settings but only 2 and a half rows show, I can remove all rows and select 4 rows again but only 2 and a half rows will show all the edit, pin etc, options are there and work and I can rearrange the tiles but if I dismiss a tile it disappears completely, any help much appreciated. please see added image.

Steps for reproduce:

• Turn ON PC
• Launch Audacious player
• Launch Firefox
• Visit to drupal.org

And I have sound glitches like on radio tuning. From all software, that have sounds: players, browser, messengers. Glitches disappear after restart. I find only 2 sites, that make it: drupal.org and my local bank. With Chrome - no problems.

Without Audacious glitches can be to, but not in 100% of cases.

OS: KDE Neon Plasma 6

Hi,

I was using FF on Ubuntu 22.04.4 LTS. Had version FF 120.x and playing video in Netflix worked fine. Then I updated to FF 124.x and playing video stopped with error F7355-1203.

I've checked the DRM setting and it is enabled, I checked addons and I have OpenH264 and Widevine installed, both set to always active.

I've checked installed codecs and I do have libavcodec58 installed. No update for that available via apt. I also have ffmpeg installed, no problem with that either. I can play Netflix videos in Chrome, but not in Firefox now. Something happened to Firefox when I updated from 120.x to 124.x. Today I updated to 125.x, same problem, Netflix video won't play.

I've unchecked the DRM setting and re-checked it, and that does reinstalled Widevine but does not fix the problem.

Any ideas what could be the cause?
