Firefox Support Forum

FF just did an update and now I can barely use the browser. Its slow and then spins and crashes... it took me 6 minutes to just get this open and type this. All my links and sign ins are on it... ugh... How do I reverse the update? thanks

Hi All,

This salesforce site is working in safari, chrome and edge but it is not working in the latest Firefox browser. It crashes after getting stuck for minutes. Is this technology not supported by Firefox?

The lag is very problematic to me, because I do most of my work using the browser. When the keyboard starts lagging I can only enter text using copy/paste with mouse (which works fine). The only way to solve it is to restart Firefox (which can result in lost work).

The lag, when it starts, is 10 seconds or more for each keystroke. It occurs about once every few days.

Ubuntu 22.04.4 LTS

126.0.1 (64-bit) Mozilla Firefox Snap For Ubuntu Canonical-002 - 1.0

I don't use Wayland.

Setting accessibility.force_disabled to 1 did NOT help.

I've been dealing with this issue for a long time now, without finding any solution

On macOS, whenever I am using Bluetooth headphones (Sony XM4, Airpods Pro), videos will hang for a few seconds just as the video is starting. This happens again if I pause/unpause or if I seek forward/backward on a video. The video "spinning animation" will appear and it will take 2-3 seconds for the video to start. This happens immediately, even if I click pause/start fast (ie: this is not after some delay necessarily). Also, if I mute audio on the video, the issue does not manifest itself.

During the waiting, Firefox itself seem to be hanging: for instance if I click on an extension icon in the toolbar, nothing will happen until the video finally start playing and then the extension menu will open up

When using Google Meet or Zoom for instance, I sometimes have to wait up to 10 seconds or so before Bluetooth Audio/Microphone starts after I've joined a meeting.

The issue is not specific to these platforms: I experience the same issue on other platforms such as Facebook, dailymotion, vimeo, zoom. On Facebook, since videos start muted, I can see the videos start playing right away, and then if I unmute sound the video stops, and start again with sound after 3 seconds or so

The issue does NOT manifest itself when playing an audio-only stream: ex Soundcloud or local radio stations audio stream

Things I've tried and didn't help - Troubleshoot mode - Different Firefox profile - Different Firefox install - Restarting my system

This feels like Firefox/macOS is waiting for Bluetooth to activate, or something like that. I have a feeling this only happens for certain types of video/audio codecs but I am not sure how to validate that (ex: no issues on soundcloud, petron audio-only posts).

The problem is entirely non-existent when I'm using sound output that is not Bluetooth.

This does not happen with other browsers otherwise I wouldn't be posting here :)

I receive e-mail from websites where I subscribe. Many times, the message from the sites (kelbyone.com, to name one) contain a graphic (jpg) that does not display in Outlook.com. Microsoft Tech Support is unresponsive. The sending websites refuse to help.

It seems to me that FF chokes on the length of the hyperlink. Here is a sample: https://kelbyone.acemlnb.com/lt.php?x=3DZy~GE2JaTN5XV.-wy5heOd~nAnuwAjluw2Z5PEIaOb5p8qy0y.0uJz2nRzit~yjvYwXncWJXCf657

If I paste the hyperlink into the search window, the page will load. When I forward the e-mail from Outlook to yahoo mail, the image displays.

I am running extensions Adblocker Ultimate and DuckDuckGo Privacy Essentials.

I would like help with this, at least, to identify where the problem is.

Have used Firefox for decades and suddenly it is having problems. If I surf around and have a few tabs open, some of them might crash. Firefox tries to restore them and sometimes it works and sometimes they just crash again immediately. I can go to Amazon and the page won't load completely so I can't do anything. If I try and close Firefox it won't close, it is frozen. And often, pages just load very slowly even though my internet connection is strong. This just started about a month or so ago. I have refreshed Firefox, updated it, and checked the systems on my computer. All my internal diagnostics returned "no issues." So it has to be the program.

Hello,

Relevant system referenced below:

MacBook Pro 2021 Mac OS 14.5 Firefox 126.0.1 (64-bit) Carbon Copy Cloner 6.1.11 (7673)

I have a case of vanishing bookmarks. I quit Firefox last evening with command-Q as I’ve done a thousand times before. When I launched it this morning I was greeted with Firefox with an empty Bookmarks Toolbar and “Getting started” message. I opened a Manage Bookmarks window and everything there was empty too. I found, as well, that all of my saved UIDs and passwords were gone except for three, two of which I haven’t used in months. Weird.

Next I opened Firefox Help and found information about Troubleshooting Mode; I restarted in troubleshooting mode but nothing had changed. After restarting in normal mode, I tried Restoring Bookmarks; I chose Manage Bookmarks from the dropdown and then clicked the button in the Library window. Restore showed only one file and it was created today with only 14 items. Selecting Choose File… showed Desktop with Old Firefox Data highlighted. In that folder was only w34y3u9y…628 folder. From there I selected bookmarkbackups and the only file there was bookmarks-2024-06-06_11…lz4, a file created at 3:33 today. I found the key4.db file and it was created at 3:33 today.

I have Carbon Copy Cloner and use it for a weekly backup to a remote SSD drive. There are a year's-worth or so of weekly backups on that device. I tried trashing Firefox and reinstalling it from last week’s backup. While this worked, it didn’t solve the issue; it was still like a fresh copy of Firefox with no bookmarks.

I’m hopeful that I can restore the bulk of the lost bookmarks from CCC but I have no clue as to which files/folders to restore and I don’t want to guess. If you think this is possible, please tell me which files or folders to replace. Should I delete the files to be replaced from the current system and if so where are they located? I’m comfortable using Terminal for basic purposes but need explicit directions for entering commands and navigating to locations or files.

Thanks for your time,

David

When downloading a file in Facebook Messenger, Firefox changes file extension to .pdf. My case was .docx file but looking for help found people have problem with other formats, even non document saving as .pdf.

Not asking for help, just reporting problem

I was able to use it normally before, but when I downloaded a file, the browser froze, so I used Task Manager to terminate Firefox and reopened it, and then I encountered this situation.

When I open the "Downloads" in Firefox, the browser hangs and prompts unresponsive. I have tried the troubleshooting mode, but it did not work, the problem still exists. I also tried to "Refresh Firefox", but this did not solve the problem either. I also tried to delete places.sqlite, but it was also ineffective. Then I created a new user profile, but the same situation occurred. I also tried to uninstall Firefox, delete AppData/Local/Mozilla and AppData/Roaming/Mozilla, and then reinstall it, but it also couldn't solve this problem. I've had this problem on both 126 and 125.

Dear Support Team,

After updating to last Mozilla Firefox version (126.0.1) all my ngx-datatable tables are overlapping all rows over the first one even if the entire height of the table is correct calculated.

This is a blocking point. I need assistance urgently.

Hi, it has been a while that one of the updates on firefox removed the ability to navigate using the middle click, i waited and waited for some day an update drop and fix that but it's been a while and nothing has come, i was sure to test this on another computer and it didn't worked as well so i'm pretty sure firefox has some problems, i mainly use a drawing tablet because i don't have a mouse, so navigating is a bit hard without the usual middle click nagivation(i'm not sure if there is an actual name to that), please help

When I attempt login to store account, I get the error below. I have uninstalled/reinstalled Firefox to no avail; login works fine in MS Edge

{"sec-cp-challenge": "true","provider":"recaptcha","provider_secret_public":"6LfU2I4aAAAAABeLkTGHOItQ5XTtsv2BpEBonIj_","branding_url_content":"/_sec/cp_challenge/message-4-4.htm"}

I started having new tab crashes a couple of weeks ago on Firefox and Brave browsers. I have looked in the extensions settings and do not have any added extensions so that did not cause the problem. I also run Norton antivirus and Norton Ultimate utilities software and regularly clean out files and scan my computer for malware. Not sure if Ultimate Utilities is the problem since I have had other problems in the past with that program. Also, I wonder if Windows updates caused this problem? This has also caused problems in the past. To get around this problem I have to copy the link then right click on my mouse and open a new window the paste the link. Very annoying and time consuming. How do I fix the continual tabs crashing problem?

Hello Mozilla Support,

I am encountering display issues with my WordPress website, which is dedicated to a fan-made game called Pokémon Infinite Fusion. The site appears to load correctly on other browsers like Chrome and Edge, but certain elements are not displaying properly on Firefox.

Website Details:

   Main URL: Pokémon Infinite Fusion
   Specific Pages with Issues:
       Pokémon Infinite Fusion Sprite Installer
       Pokémon Infinite Fusion Calculator

What I Tried:

   CSS and JavaScript Debugging: Checked and validated CSS and JavaScript for compatibility issues.
   Browser Cache Clearing: Cleared the cache and cookies in Firefox to ensure it wasn’t a caching issue.
   Add-ons Disabled: Ran Firefox in Safe Mode with all add-ons disabled to see if any extensions were causing the issue.
   Responsive Design Mode: Used Firefox's Responsive Design Mode to check how the site renders on different screen sizes.
   Error Console: Reviewed the Error Console in Firefox to identify any specific errors or warnings.

What I Expected:

I expected that the website would display consistently across all browsers, including Firefox.

What Actually Happened:

Despite my efforts, certain elements on the site, such as images and interactive features, still do not display correctly on Firefox. These issues are not present on other browsers, which suggests a compatibility problem specific to Firefox.

Questions:

   Are there any known compatibility issues between Firefox and certain WordPress themes or plugins that might cause this problem?
   Could there be specific CSS or JavaScript practices that work in other browsers but not in Firefox?
   Are there additional tools or techniques in Firefox that I can use to diagnose and fix these display issues?

I would appreciate any advice or suggestions on how to resolve these display issues. Ensuring a consistent user experience across all browsers is important for my website.

Thank you in advance for your assistance!

Best regards, Saimhbx

Firefox crashes. I tried to enable safe mode in the browser and there were also crashes. browser updated to latest version bp-a4cfcddb-2647-4541-98b0-912f70240605 bp-d2d0e21d-ec26-4fb4-9bd0-2d97e0240605 The browser crashed 15 times in a day, I’m already tired

i formatted my computer, and used last session .Json files to restore my tabs from before. this allowed me to have my tabs. but even weeks after reinstalling, Firefox does something uncharacteristic. it opens with one window with one tab. then after a second or two, it closes. and then reopens with all the tabs. I would consider a re-install but i don't want to lose the tabs again, and i have 2 computers with different tab sessions (different users on the reformatted one as its a family computer)

its functional but annoying. What can i do?

i would include screenshots but you can't really screen grab a PROCESS, so that doesn't help here.

i am running windows 10.

Greetings, every so often I'm having an issue loading pages for certain sites that aren't sketchy at all. The most recent one is TireRack.com. I'm shopping for tires for my car and Firefox is loading all the other sites I've visited but it won't load any page from TireRack. They are a legitimate shopping site. It happens from results of a Google search but I've also tried typing the main page of the site's address into the address bar, clicking various other links that display below the actual search result that go to other pages within the site, etc. The site loads fine in both Chrome and Edge. This happens every so often and it's always a legitimate site and the exact same behavior. I can't recall any other specific sites at the moment but it's enough to have me pretty irritated today as when I'm shopping I like to have multiple tabs open with all my options for comparison and price considerations and today I have to have one of them open in a different browser which makes it much more difficult to keep tabs on especially where I'm used to only having one browser open for all instead of having to remember that one of my options is open in another browser. I have glanced through my browser setting as well as my windows security settings but I could spend hours in there trying to figure out things and potentially breaking other things myself, which I don't like doing. Any suggestions or other info on what could be going on will be much appreciated, and thanks in advance.

Ray.
