Firefox Community Forum

I can't log into chase.com from Firefox, which I've been doing for years. I get an outage message. But down detector shows nothing. It went on for days so I tried Microsoft Edge with Bing and it works. Is there some Firefox setting I need to change?

Gentlemen, isn't your browser using a lot of RAM? I've been freaking out about it in recent years. That's only with 25 tabs open!! Despite the fact that the system was installed just a day ago, without any tweaks!!!

For quite some time now, I am unable to sign in to my account at CanadianTire.Ca I get an error. The signon process goes to CustomerAuth.Triangle.Ca for the email and password input. When I click "Sign In" the return message is a yellow triangle followed by the word "undefined" (see attached).

All other browsers I have (Brave, Chrome and Edge) can sign in without issue.

I noticed that other users have the exact same issue. I have tried all solutions I could find. The browser is up to date as of today (150.0.2 64 bit). I tried troubleshoot mode, clearing the cache, deleting cookies, history .... On the web site I turned off ETP for CanadianTire.Ca and CustomerAuth.Triangle.Com.

I have used Firefox since it was v0.93.

Hello, I've been watching MSNOW at 4pm eastern and after about half an hour it crashes. I get a message to send a report and restore the tab. I restore the tab which works for maybe ten minutes and crashes again. I am using Windows 11 on a new computer. I'd appreciate some assistance. Thanks. Bruce Caress

Moderator note: This question has been edited to precise Firefox and OS version, based on the crash reports.

This has happened randomly on several different computers, both windows and ubuntu linux. It just now happened on my Win 11 computer. Was viewing the CNN news site and FF suddenly closed, without a "FF crashed..." message.When I clicked the icon to reopen it, it came up with the home page group of tabs instead of reopening the windows and tabs that were opened when it crashed. Worse, none of the previous months of history shows up and recently closed tabs and windows are both greyed out.

Is there a way of recovering the history of what I was working on at the time of the crash and what the hell is causing this? I am close to dumping FF and going with something else as this is highly annoying.

Здравствуйте! В настройках установлено "запоминать историю", чтобы появлялись подсказки в заполнении форм. Однако эта функция не работает, а она мне очень нужна, так как я часто заполняю формы одними и теми же данными и значениями. В чем может быть проблема?

Hello,

Since a recent update, I can no longer drag and drop files from the Firefox downloads panel directly into Outlook Web (webmail) as an email attachment. This used to work fine before.

Steps to reproduce: 1. Download a file (e.g. a PDF) 2. Open the downloads panel (the arrow icon in the toolbar) 3. Try to drag the file from the panel into the attachment area of a new email in Outlook Web 4. The file does not get attached — nothing happens

Expected behavior: the file should be attached to the email, as it was before.

Workaround: I have to open the downloads folder via the folder icon in the panel, then drag from Windows Explorer instead.

Firefox version: 150.0.2 (64-bit) OS: Windows Webmail: Outlook Web (outlook.office.com or outlook.com)

This is a regression, it worked in previous versions. Is there a fix planned?

Thank you.

I am getting the message "updates are disabled by the admin." I am the only one here so I don't know how that happened. I need to install Slack but need to update first. I followed the steps to edit registry but still can't update. Please advise.

When I click on option/link for "Print using the system dialog box", the print preview no longer works. Instead I see message "This app doesn't support print preview" in preview pane.

When I press F12 to use the developer tools and try to change the width of the panes by click and drag the divider there now seems to be a limit to the panes width that was not there before. I'm not sure with what version I stated to notice this. I use to be able to drag the right hand panel fairly far over to the left and could take up about 75-80% of the width of the developers window. Now I'm guessing that I'm able to drag the right panel to a max width of 35-40% for some reason. I have not changed anything in the about:config page. I'm not sure why I can't drag the right panel to cover the 75-80% of the window that I had been able to do.

Is there a setting in the developer tools or on the about:config page that sets the max width that the right hand panel can be dragged to the left?

Since April 27th have been various situations where this msg occurs: Access Denied You don't have permission to access ht tp :// signin.ebay.com/logout/confirm?" on this server. Reference #18.17fc3117.1778464971.41591197 An error has occurred

Although the letters in the reference can be different.

1. Trying to open E-Bay with an icon presented in Firefox for E-Pay, or searching Google for 'E-Bay Login', in Firefox, Edge, and Chrome this msg occurs. 2. If I can sign on, when opening searchers from a folder the searches:

	A. Some searches have the words, and show items for sale, but the rest have the access denied msg where the search words should appear. 
Will send a pic when can sign on.

2. If E-Bay will open, sometimes all searches will load ALL with the search words visible in all tabs, but when click on a link for an item to sell, the access denied msg occurs. Sometimes a few searches will load with the name of the search in the tab, but other searches will load with the will load with the words access denied, and the mas when clicked. 3. Some website like Arkaim of some such issued this msg: Your IPv4 Address 104.187.9.142 received a bad risk score. 4. Left msg on Firefox about above, no response, left 2 msgs on E-Bay Technical Support, no response, Microsoft no help, Dell no help, AT & T sent new Gateway/Modem.

IP address changed, and IPv4 changed to  IPv6. Same problem.

At & T said the old router was slower than I paid for: Speed Test 210.6, 29.7 New router 475.5, 225.8. Google AI says clear cache: Clear Cache on Desktop (Chrome, Edge, Firefox) [1, 2, 3] 1. Open Menu: Press Ctrl + Shift + Delete (Windows) or Cmd + Shift + Delete (Mac). 2. Time Range: Select "All time" to clear everything. 3. Select Data: Check "Cookies and other site data" and "Cached images and files". 4. Clear: Click "Clear data" or "Clear Now". 5. Restart: Close and reopen the browser. [1, 2, 3, 4, 5] I saved the icon of Network & Internet, Internet Options to delete temporary files, history, cookies, saved passwords, and web info (same Thiong??????) Lastly Google AI recommended editing the DNS to Google (8.8.8.8) or Cloudflare (1.1.1.1). Any danger in doing this?

Hi,

I shared a lot of important tabs to my laptop (using the firefox built-in share/send to other device button), upon starting it, they seemed to arrive just fine and opened on my laptop, however I accidentally clicked to "history"->"restore last session", which made this firefox window go away and all my sent tabs seem lost.

Is there any way to get them back? Any type of log?

I tried the following already: - Looking through History (they do not appear there at all) - Looking at recently closed tabs (there aren't any listed) - checking synced tabs window (did not contain the ones I sent from my phone to my laptop) - checked session recovery files ( none of my synced tabs seem to have gotten stored into that session recovery file)

So is there any other log or place I can look at? I refuse to believe that this is not saved anywhere? Or on mozilla servers at least? Can support help me?

Thanks for any ideas!

EDIT: I found this, may is something similar: https://connect.mozilla.org/t5/ideas/send-tabs-log/idi-p/15640

I use Firefox frequently as it is the most useful browser I have. I want to keep a clean desktop and do not have icons on my desktop. Every time Firefox updates, it places an icon on my desktop. I do not want it there and delete it. It is very, very annoying to have to delete every time there is an update. How can I keep that from putting it on my desktop? If the thinking is that if it gets put there, I will use it, that will be what keeps me from using it. If I cannot find a way to stop it, I will remove the program altogether and figure out a way to do the things I currently do with Firefox. Please let me know how to accomplish keeping my desktop clean.

This issue just started today.

I was attempting to watch a video on patreon, and normally I pop out the video so it is larger. This normally has no issues.

But today when I hit the button to pop it out, Firefox crashed.

Firefox then updated, so I thought maybe it was just because it needed to update.

I attempted this two more times with the same result. 

The first like I normally do where I start the video and then click the "pop out" button. Then the second time with the video paused. The minute I click the pop out option Firefox just crashes closed either way.

ie every time I closed it it would reopen- 14 times when I am trying to read my emails yesterday and 6 today. but I thought it was my internet security causing the problem. I kept getting notification that a certain site was attempting to use my system,. The worst thing was it kept flashing on my screen and wouldn't go away, There was no clue who öwned it, my security or Mozilla's. It was finally resolved by contacting my computer guy, but we never identified the source. the site that was being blocked started with pssst.........com, or something similar but it was driving me mad trying to get it off the screen. If this happens again, how do I get rid or stop the continual notifications? Of course I have nothing to show you as I have since deleted it, sorry. as I was just relieved to see it gone.

Thank you Angela Johnson

My Firefox 150.0.3 (64-bit) in Windows 11 on a Dell 9310 locks up when the XPS is put sleep and awakened after 5-minutes or so. No recent Extensions or Add-ons have been installed. I have yet to delete and reinstall Firefox, maybe that's the next stop. I just can't find the problem with my limited tools and experience. Thanks, and appreciate the help.

I was trying to do something with my bookmarks yesterday and I must have pushed the wrong icon. Firefox then became unavailable. I'm 88 years old and not fully at home with computer language. I tried Chrome, but it's not available like Firefox.

Over the past few weeks, my typing is continually being interrupted. It did this a few years back, but this is getting very annoying and I am soon to switch browsers if not fixed. BTW on any machine using Firefox, this is happening
