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!

I just got my PC back from the shop. It's the best LG Gram laptop they had with Windows 11, and it's 1-yr old. Much on it was corrupted and I'm having to reload many items, one being my Firefox. It wouldn't open up. I did the right-click on my mouse and hit the OPEN selection. Firefox still wouldn't open up. I reloaded Firefox hoping that it would correct whatever may be wrong. No, it still won't open up. I'm reaching you now via TOR. My TOR was also reinstalled, but it is able to open up. Can you think of what I may have done wrong? [I'm unable to check the option-email me when someone answers my thread {this email must be a thread}, but this will be fine.] Please note that I am so NOT tech-savvy, I don't even have any smart/mobile/cell phone. Just a plain old phone. (I should add I'm in my 70's, ill, and in a Nursing Home.) I looked through your troubleshooting sugggestions, but they are too fancy for me to understand. I'm not sure how this works, but I sure do hope you can offer some suggestions as to what I can try. Thanks so very much for your time and consideration of this matter. It's very much appreciated.

• 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?

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.

Firefox continually refuses to open, and I have worked all the suggested solutions once again. I used it for a few hours this morning, switched briefly to Chrome. Went to go back into Firefox, and it wouldn't open again. Did all the work arounds....uninstall, reinstall, even system reset to the previous day. Still won't open. I am so disappointed at having it behave so unpredictably. I sometimes sense it is related to updates....almost afraid to reboot my computer sometimes because it will not open afterwards. My recent install attempt appears among the public users, which is not the case as mine is a private PC. The Mozilla Program itself, however loaded to the 86 bit program files. Not at all sure to proceed at this point.... getting forced over to Edge it feels like....

I Have Had It Installed On Microsoft Edge For About A Year With No Problems. I Had It Installed For About 3 Months On Firefox Then I Needed To Install It Again & I Get The Above Messages. Why Is It Doing This? There Hasn't Been Any Harm Done To My Computer. Also Firefox Needs A Customer Service Phone Number For People To Call & Explain Their Issues It's A Lot Quicker & Easier To Solve Your Problem.

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.
