Firefox Support Forum

The story is when I accidentally clicked on a sick video, YouTube start to recommend me similar sick videos.

So my question is how does YouTube get my identity?

I'm not logged in. my profile is actually a snapshot, so when I restart Firefox, it go back to the snapshot. I even restarted my ISP router to get a new IP address. This did not work.

Only when I create a new profile with "firefox -P" does YouTube start to see me as a new person.

So how does YouTube identify my Firefox profile? I don't think it's in the https request headers. Weird.

I simply want to use a password to open Firefox. I don't want to set up Firefox sync. How can I set up a simple password as permission to open Firefox without accessing sync?

Hey there, I had two windows in firefox open, one of which had a lot of tabs. I was using firefox on my surface pro, and then got up to get a snack. I came back, and the window, which I had been using for some time, was gone. The other window was still open, and firefox had not been closed. I thought I would just open it up by restoring recently closed window, but it was gone. I routinely clear my history, but even tabs that I just had open 5 minutes ago are missing from my history, like I never opened them in the first place. What is going on?

All downloads I make inside of Firefox are automatically failing, with "Failed" message. This only happens in Firefox, Microsoft Edge downloads are perfectly fine. I've tried starting in troubleshoot mode, disabling anti-virus, clearing cache and downloads, rebooting PC.

Some recent changes in PC include: changing TEMP and TMP system variables to another drive (I've changed them back to C drive, had no effect) and making C drive a dynamic disk. Yesterday downloads were working fine. Thanks in advance.

hi

i just got firefox setup just as i want so dont want to reset it. yes i have used arkenfox to beef up pivacy.

only problem is i assume fingerprint disabling has made the window size like tor browser.

does not work

how do i fix this? using this method? as i would prefer to do this way

alternatively prefs.js / is there a way to do it there?

simple step by step instructions please

your time and help is appreciated.

Not sure if this is a new 'feature' post-update but it's damn annoying. I was busily transferring some photos that I'd taken on my phone over to Firefox on my Mac. Wasn't until I went to find them on the Mac where they would normally be and couldn't find them. Bit of digging, opening up the Download 'history' on Firefox and saw "File not downloaded: possible security risk".

I can see that I can disable this 'feature' but it seems to be a global "allow". Is there any way I can tell Firefox to allow any downloads from my devices on my network yet warn for potentially insecure downloads from the web?

TIA

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?

When I try to customize the toolbar in Firefox 115.10, the browser tries to change the page to the customize toolbar / overflow toolbar page. However the page flashes on and then reverts to the normal browser page. The page showing customize toolbar/ overflow toolbar, is transient and does not last. So I can't even customize the order of the buttons on my toolbar. This wasn't a problem a few days ago before the switch to this latest version. In particular I am trying to change the position of the "home" button to the left side of the address box. I just can't bring up the customize toolbar page. I'm not talking about the position of the add-on or extension buttons...just the home button. Hope this is clear. By the way, I've even tried this in safe mode to no avail.

Hi,

First, this is not a complaint. Firefox is an outstanding product that makes me very happy.

I though I could post the following, because this community strives to make it better.

In a nutshell, I have a very fast Internet connection, up to 6Gbs/1Gbs speed, and Firefox is not able to go over .9/.8

I attach are 2 tests, one with Firefox and one with Chrome.

Note that when using it for anything else than speedtest, Firefox does not feel slow at all.

I'm not requesting a fix, just thought that somebody would like to know.

Hi, i just got a new laptop (Asus Zephryus G16, 2560 x 1600 screen) and after installing Firefox there is a thin white border to the left of the screen when running in fit screen. This problem is not present when in a windowed mode or in F11 full screen.

I tried updating the Intel Arc drivers but this did not fix the problem. Changing to compatibility mode also did not fix te problem.

PS: in the uploaded screenshots it is quite dificult to see the white line(because the background is also white), but when the image is viewed in a new tab it is visible.

Thanks

Hi.

How come there is no option to turn off "Firefox Translation"? I speak three languages and every time I visit foreign web site, Firefox suggest translation to me. It's annoying.

Hi,

There many extensions such as:

https://addons.mozilla.org/en-US/firefox/addon/search-on-imdb-context-menu/ that say when trying to install:

Installation aborted because the add-on appears to be corrupt.

I am using Firefox Developper Edition, with extensions.langpacks.signatures.required set to false.

This addon, after download, installs fine as a temporary addon.

How can I install it permanently?

Thanks.

I am having a very frustrating problem that is driving me huts.

Just the other day I was commenting in a text box like this one and I hit caps lock on my keyboard and a little grey box I had never seen before appeared with a locked lock. Then when I hit caps locks again on my keyboard an unlocked locked appeared in the little grey box. But it stays in cap locks and no matter what I do it won't go back to lower case. And when I say nothing shuts it off I mean its doing that on every site I try to comment on. Shutting down the browser does not help. And the only way I can get caps lock off is to actually shut down my whole computer and basically start all over.

You community volunteers are the best and quickest help I can get so I went straight to you for help.

Hi After the latest update, the address bar dissapears everytime I click on it to type in an address. It gets hidden behind previous addresses I visited. Completely unusable. I have no idea why it is so bad and how to fix, please help. Thanks

Just in the last few weeks, "buttons" on web sites do not work in Firefox, but work fine in Chrome. Example: https://www.mealtrain.com/users/sign_in/ The sign-in button does nothing in Firefox, yet works fine in Chrome. V. 125.0.3, Windows 10.

Hello

Since an update from a few days ago (May 2024), my address bar/search bar is now basically outside of my PC screen, see here: https://vimeo.com/948314161

It's not a local problem, it's also happening on other PCs/Laptops I have.

How can I fix this? PS should the answer be that I need an add-on or anything like that, then it's bye bye Firefox, hello Chrome

Thank you
