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 am using Firefox 125 in Windows 11. And this just happens recently.

Sometimes, quite frequently, when I click the addressbar wanting to input or select a new address. The Firefox UI freezes (before the dropdown list of addresses is shown). The video/audio/other effects are still working, and from task manager, it does not cost more CPU/mem than usual. But it does not response to key press or mouse action. All I can do (that I know of) is killing the processes. The problem does not seem related to "current" webpage I am browsing. And I have not installed new addons for a few months.

Any idea what should I look into?

Hello Good People,

I noticed that the snap version of Firefox had a lag issue when typing into input field. For example, when composing an email and wanting to use backspace to quickly delete a misspelled word, then backspace works slowly, stuttering and jittering. If I hold down a key in the input field it also lays the character down in a stuttery, slow way.

I tried reinstalling the system and that solved the issue. But it has returned again. Maybe it was an update. I also installed WINE and waybridge to get some windows plugins to work on my DAW. I don't know if that has affected it.

I also tried removing the snap version and installing firefox using the terminal but the problem persisted.

It's an annoying problem. Any advice appreciated.

Just recently Firefox seems to have its downloads capped at 15-16 meg speedtests show the full 1Gig speed OPERA AND EDGE both download at the full 999 megs but firefox has recently stopped downloading any faster then 19 meg

what in firefox could be causing this its not happening in any other browser.

Device: Surface Pro X SQ2 OS: Windows 11 Home for ARM (Up-to-date at time of writing) Firefox Version: 125.0.3 (AArch64 up-to-date at time of writing)

I am having an issue with Firefox and video playback, specifically on YouTube. When I play a video in default view mode, the playback is super choppy / low frame rate. When I change to theatre view or full screen, playback works perfectly.

I've tried incognito windows and troubleshooting mode with no improvement.

Microsoft Edge works fine.

Not sure where to go from here.

I've set up a second profile to keep my personal and work browsing separate. When I reopen my non-default profile, it doesn't restore the previous session's tabs. I have "open previous windows and tabs" checked under Settings > General > startup in both profiles. Please advise.

Recent issue, April 2024. Had version 124 Firefox on Win10 computer and went to Help - > About to have Firefox check for updates. This has worked just fine up until now. The message "Failed to check for updates." is shown in the About screen. I have uninstalled and re-installed Firefox with the same results. Have also un-installed Firefox, un-installed Mozilla Maintenance, then removed Firefox data from App Data folder in user directory, then re-installed with the same results. Also, now when I access a local media server, I keep getting the message "Firefox is installing components needed" and that never goes away. Any ideas?

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,

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.

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, 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,

Firefox Developer Edition 126.0b7 (64-bit) shows a perpetual "Loading" screen when trying to access my internal Logitec Media Server at 127.0.0.1:9001.

Other browsers like Waterfox Classic have no trouble, so LMS is working fine.

I tried cleaning the cookies, disabling the firewall (Windows 10), that did not help/

Any idea how to solve this?

Thanks.

Hi, Before Firefox's Version 125.0.1 (64-bit) latest update I could download any file from my safe office environment, behind firewalls, VPN, ... Now despite of unchecking the "Block dangerous downloads" I'm still unable to download files. I have Windows 10 on my laptop.

Here are the steps: Click on a file, Save "File not downloaded. Potential security risk." Click on the message - Allow download The result is a file with content "HTTP Status 405 – Method Not Allowed".

Please help me to work the downloading again. I am aware of the safety but I want to switch off this feature.

Thanks in advance for help, Tibor

When trying to install any extensions on either the Mozilla Addons website or directly via the Extension settings, it fails to do so.

I've attached a screenshot of the Mozilla Addons website when it fails to install the extension. On some other addons that I've attempted in the past, it just shows the throbber forever.

I have checked the Multiprocess Browser Console and it says that it fails to move the file because it's locked (NS_ERROR_FILE_IS_LOCKED). I have also attached a screenshot of that.

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.

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.

Locking this thread, please continue here: [/questions/1446495]
Unlike Safari, Firefox doesn't autofill passwords or 2-factor codes. Please implement these features or tell me how to get them to work. MacOS 14.4.1 Thank you, Steve

Hello, I just got a new laptop with windows 11. I just did the latest update to Firefox. Everything is a little large but an internet search addresses these: BUT.... The 'bookmark this page', the star in the URL line, menu is small and the fonts are micro. Zooming or changing fonts in the hamburger menu doesn't correct this. Attached. Thank you.
