Firefox Support Forum

after creating a new profile, and copying everything in the root directory to the new profile, including search.json.mozlz4, the default search engine setting does not get transferred over and is still set to google

about a month ago youtube was only letting me watch videos in 720 or 360, as of about a week ago i only have 360. i've disabled every single extension i have and i have firefox version 127.0.2.

i'm not having this issue in edge, so i assume it's firefox specific. anyone know what's going on or what i can do?

hey all. i'm inquiring about how much longer it will be until the URL bottom left corner of firefox on youtube.com bug i reported here is fixed: https://github.com/webcompat/web-bugs/issues/135606 . asking here because i asked on the issue page (the link) and nobody responded :(. thanks so much!

• Firefox 127.0.2 (64 bit), Windows 10, all extensions disabled.
• Tested also with a clean portable version (same Firefox version).

In private mode, on Google Images, large images (in the preview pane: if you click on an image in the search results) are sometimes (but not always) blurry. This is not the case in the "normal", nonprivate mode.

It works fine on Android, and other browsers also work fine. I have had this issue for a very long time now, but only now realized that it's a private-mode issue.

Example, which is reproducible for me: Search "site:linkedin.com new york" on Google Images and pick an image with a sufficiently large resolution.

Hi! From some time now i have problem with GUI elements overlapping each other. It started with the window control buttons (that part, where you can close the window). Esthetics aside, it was not that big deal, so I just ignored it, but some time ago similar overlap appeared on address bar - so now I don't see what I'm writing. This is a big deal, now I can't really tell if I made a typo, I'm not able to correct it or I can't see if what I'm writing is mixed with original url, stuff like that.

I'm on Manjaro Linux and Firefox version is 127.0 (64 bits) I've tried to reinstall Firefox with different sources, like Flatpak for example, but the issues persists. Has anyone an idea how to fix this?

David, here are two screen shots (ss) to clarify my issue with email and a third regarding another issue (see below).

Number one ss shows what I see when I go to Thunderbird. I am allowed to delete if I wish by first marking the email and then clicking delete. If, however, I wish to view the message, Number two ss appears. I cannot delete the message without going back to Number one ss as that option has now disappeared. This was no problem on my old computer.

The other issue is related to the above. I have over 250 emails without being able to access them (see Number three ss). On the left upper side is the number of emails I have, but only six old emails appear, something that is confirmed in the upper right frame. No matter what I do, I cannot access them.

Unable to export Firefox bookmarks. When I go to 'Manage Bk Mks' it states 'no items' (See attached Print Screen) yet all my bookmarks show in the left hand pane.

Background (2024): Created my userChrome.css file, on my desktop, 4 or 5 years ago when I was using Windows 8.1. At best I am an experimenter with userChrome. Last year, due to another problem, I had to update to Windows 10. So far, so good. My userChrome file held through the update.

Fast forward: In May I had a hard drive crash (total DOA) and had to buy a new desktop (Dell) with Windows 11 (I almost regret that), 64-bit. Also using FireFox 127.0.2. After more than a month, most of my software and files are working again.

Current problem: My userChrome file is not working as it used to. I had it backed up to other places, so I know it is not the file. I am missing the “tabs bar”; the one with the FireFox icon at the far left, then (in my case) a Google box, and then the “+” for Tabs.

That bar is missing and I can not figure out why. I suspect something changed in Firefox. I do not see how Windows 11 (god forbid) would do anything like that.

See attached image.

I can not create additional tabs or move between them.

I suspect that the “solid” black bar after the Bookmarks toolbar(s) may be involved.

My “colors” seem to be OK and the location of everything else is acceptable with the exception of the “Find in this page (Ctrl+F)”. The ‘magnifying glass is in the correct place on the second bar but the box to enter data is at the bottom. The box used to be just in front of the ‘magnifying glass’. Not as critical as the “tabs bar” but annoying.

Don't see how to attach my userChrome.css (as userChrome.txt). I can supply the file or post it.

Can anyone make a simple suggestion for a simple senior citizen?

Every time I use YouTube on Firefox it feels like a mental torture. It starts off with micro-stutters initially - annoying but nothing crazy. After some time the loading speed of the website and the videos themselves increase dramatically. And eventually it becomes unusable:

• Scrolling feels like the website is running at 30 fps
• The videos take several seconds to load
• It also takes multiple seconds to catch up when you select a specific moment of the video

The only solution so far has been restarting Firefox entirely, just close and open and pray. Then the problem comes back after some time.

Solutions I Tried:

• Disabling AdBlock (didn't work)
• Enabling Hardware Acceleration at all time (didn't work)
• Uninstalling unwanted Extenstions (didn't work)

All of these problems disappear when using Chrome or Edge.

Machines are Win10 and Win 11. Current FF = 107.0.2 I have several PC's, previously NOT synced. All have overlapping bookmarks - some unique, others the same. My question has to do ONLY with bookmarks. My main concern is how to do this across multiple different machines - not all online at the same time - and NOT LOSE DATA!

1. When I sync machine A with machine B, I assume entries that are different are copied to the server AND then duplicated to the machine that did not have it.  Q:  Is the item that determines the uniqueness the NAME or the URL?

2. For entries common to both machines: copied to server, left alone on both machine. Q: To be considered the same - do they need to have both same NAME and Url? 3a. Same name but different url? What happens? 3b Same url but different name? What happens?

............................ Now assume we have 2 synced machines with identical bookmarks. What are the rules / priority sequence concerning the data interactions (specifically deletion ) when one machine is offline and the other adds / deletes a bookmark, and the offline machine has made some additions and deletions before it comes back online (eg. signed in)

TIA. Clifton

I added a secondary email to my account last September--or so I thought. My profile currently shows only the email I log in with. When I try to add a secondary email, I am told that another user has registered this email (same response for two different emails). Note that I regularly receive email from Mozilla at the secondary email address. Why isn't this showing up in my profile?

I've been using Firefox since the very beginning, and try to contribute to support it and Thunderbird when I can. But today, in order to get messages from my health care provider at Kaiser Permanente -- kp.org -- and get a document I needed for physical therapy, I had to sign in via Microsoft Edge in order to log in to my member account. On my Windows 11 Pro computer, I kept getting the message shown in the attached screenshot = "this page isn't redirecting properly".

I WAS able to sign in to kp.org from my mobile phone, but couldn't download the document from there. But at least I was able to send an message to my doctor asking them to send me the document via snail-mail.

At first I thought the problem was the Kaiser web site (which admittedly is pretty gawdawful). Didn't have time to pursue it last week, because I was attending an all-day class Mon-Fri. Finally today, when I got the same Firefox error message, I tried to access kp.org via Microsoft Edge. Sure enough, it worked.

Then I searched Mozilla support, and found a closed message thread indicating that the problem had theoretically been "solved" by some sort of programming fix as of June 12th or thereabouts.

I do NOT want to switch to a browser maintained by Monopolists'R'Us. I still bear a grudge because about 30 years ago they killed or marginalized two of my favorite programs (Lotus and WordPerfect) by giving away Excel and Word for free with Windows. Even if I LIKED Microsoft, the default user interface is cluttered with too many cutesy-poo widgets and AS (artificial stupidity) "help" that I do not want. But I'm an old lady (84), and if I need to communicate with my health care providers, I will have to use whatever method works, no matter how much it galls me.

Hope you guys can find a fix to this problem that works for EVERYBODY (including me). Thanks for your attention.

I'd like to use my NAS download application to handle magnet links. How can I do that with Firefox?

For mailto: links, you can specify web apps like GMail, same for e.g. IRC. However, for magnet: links, this is not possible, only local applications are supported. I even got an error message by the web application offering to configure this, saying the browser didn't support configuring this protocol.

After years, I changed my default browser to Firefox instead of Safari. However, in spite of my careful searching and attempts to solve my problem(s) with preferences and reading help FAQs, I am unable to resolve the main issues. I am unable to go to LinkedIn, either my own page or anything else in Firefox. It goes to the page and remains stuck trying to log in. I can copy the url address and paste it into my Safari browser bar and all proceeds as it should ad I get logged in, etc. There is also an issue with my NYT digital account. Sometimes Firefox acts normally, signing me in and allowing me to read articles and so forth. But often, capriciously I would say since it makes no sense at all it will arrive at the lage and for an instant I'll see the article, or video, and then the page will go blank. Reloading produces the same result and I am unable in Firefox to see the content. If I go to the content on Safari, all is fine. I am seriously considering returning to Safari as my default browser. What is going on here? Thank you.

Dear Support. My Mac audio settings are set to output to channel 11 - 12 of my multi-track audio interface. However, Firefox's audio output only shows up on channel 1 -2. Can you help?

Thanks :)

Hi, I can't open my gmail or youtube in Firefox. I run Norton Security and recently signed up to their 'clean up' software, I think this may have removed google cookies? I can access mt email by installing Chrome but I don't want it on my pc. Help!
