Firefox: форум сообщества

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?

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.

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.

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.

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 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.

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.

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

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.

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.

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

i tried firefox, zen and librewolf but every of them has the same problem. smooth scrolling is sometimes good but sometimes so slow and laggy, especially in a tab that has a video. in tabs that has a video always have that issue and tabs that not has a video does it sometimes. its like scrolling is in 60hz when it happens. i tried uninstalling lots of times but didnt fix.

I have always used Firefox. Today - some update has erased all my bookmarks. it says import from Edge - but I don't use that. I lost my job last month so all my bookmarks are so very important and now they are all gone. OMG

Please help.

since v150 came out ive been having an issue where i get a flash of white on start up if i have Homepage and new windows as Firefox home with a wallpaper... i have re-installed firefox and tested it as default and it still happens. seems the wallpapers have a delay till it displays properly.

Ever since the last update of the Firefox program, I am frequently getting the "Server Not Found" message when I click on links online. If I switch browsers, the links work just fine so it is obviously Mozilla's problem and not anything with my "modem or router" as I am told int he "what can you do about it" message on this error. Mozilla needs to look into this problem and update whatever is causing the failure to link message.

Firefox FREQUENTLY totally removes added applications attached and it totally screw up my ability to access anything when you remove my Bitdefender application from access then I have to again EXPLORE added applicaitons!!

video downloadhelper is not saving the videos to vdhelper folder any longer. how do I change the folder location for only the video downloadhelper. its going straight to download folder.

thank you for your assistance.
