Firefox Support Forum

Starting with my bank's web site, my user name/password is being challenged. I can't bank. Elsewhere, where my desk top has always been recognized, I'm now forced to log in each time...and I receive an email that a new device has just logged into my account. All of this suspiciously coincides with a recent browser update. On my bank feedback it's showing as Firefox "125"...when all previous logins were recorded as Firefox "124". Help!

Firefox removes the exceptions after every update and they have to be manually re-added. This is a very frustrating user experience. Can you please help me identify if this is an issue with Firefox that can be updated or is it an issue with some setting I have setup.

Exceptions that get reset - Cookies and Site Data, Pop-ups, Add-ons, etc.

Permissions that get reset - All of them Location, Camera, Microphone, etc.

• Side note, the Troubleshooting Information section below has a link to share data, that link does not open in a new window. It opened in this same window, erasing all the content I had typed up the first time.

I want to use the Advanced Preferences (about:config) to select 'Manual proxy configuration' setting. I have been able to set the HTTP Proxy and associated port but I am unable to find the setting in Advanced Preferences that will select Manual proxy configuration. Could someone please help. Thanks

Greetings, I am Alvimutmex. A "not supported" notice shows up each time the Mozilla browser loads a webpage. After looking through the settings, I discovered that Mozilla has to be updated. Could you please help me update Mozilla? For instance, when I attempt to open (https://phoneinsurance.us/), I get an error warning.

Recent issue, April 2024. Had version 124 Firefox on Win10 computer and went to Help - > About to have Firefox check for updates. This has worked just fine up until now. The message "Failed to check for updates." is shown in the About screen. I have uninstalled and re-installed Firefox with the same results. Have also un-installed Firefox, un-installed Mozilla Maintenance, then removed Firefox data from App Data folder in user directory, then re-installed with the same results. Also, now when I access a local media server, I keep getting the message "Firefox is installing components needed" and that never goes away. Any ideas?

I keep getting this message that pops up in a private window to restart to keep using firefox. Everytime I click restart Firefox, it closes my tabs and opens them again. However, 5 minutes later the window pops up again. Even after repeated attempts of updating, even doing a full restart on the computer, Firefox continues to send this window to me. The private window in the bar says about:restartrequired.

I've tried uninstalling Firefox with a fresh install as well as doing a Refresh of Firefox. Neither seem to solve this problem.

The RAM usage increases, from 1GB to 40GB+ within a matter of minutes of starting Firefox. I have not added any extensions in months. I turned of several with no improvement. I have 6 tabs opened. Firefox has crashed several times the past couple fo months. I have been away on travel for 2 weeks, and today the problem is much worse.

Firefox (37916) 51GB, Extensions (34308) 370MB, GPU (33072) 298MB , and everything else < 100 MB.

I really love Firefox - use across my 4 devices. Only on my desktop am I seeing this. Laptop, iPad, and Android all work fine. Running Win 11

The 'add "outlook.live.com" as an application for mailto links' keeps popping up continuously after I click to X to delete the banner message. How do I disable it? Firefox should have a "don't remind me again" option. I do not want to add mailto links or make any changes. Thank You!

Concurrent with the most recent automatic windows update (may or may not be the problem), Firefox with duck-duck-go will not go to almost any site. All I get is a spinning icon or a blank page, not even any error messages. This was even true trying to go to this page until I restarted in trouble shooting mode. Until I can get Firefox working again I have been using Chrome with duck-duck-go. Note any search, i.e. 'hotels in Italy' or even 'MSN' do the same: spinning icon or blank page!! Any help would be appreciated. Also I noticed that my bookmarks were missing and there was no bookmarks drop-down on my tools line. I have run malware bytes and it showed clean, same with CCleaner. I have re-installed Firefox; no difference. Please help. and also, any way to find and replace my extensive bookmarks list? I have reduced my privacy to near zero and turned off firewalls and all limits I could find while testing for that. That did not change anything.

Hi I wish to have Firefox 125.0.2 and 124.02 'separate instances', not different profiles...

I already have 125.0.2 installed with various Profiles.

I found a 'few' links and they were quite 'cloudy' and also since Firefox (now) does not have the 'ask you WHERE to' install... I vaguely remember years ago, it was possible.

I do not mid doing tweaking, I also already have backups of profiles, just in case!

Thank you in advance M

PS it seems Mozilla does not want us to install multiple instances (perception)!

Longtime FF user (15+ years); just back from a few months of testing another browser and noticed strange labels for Google Contacts in FF125.0.2 (64-bit) (see attached). Any idea what's happening with that?

...and while I'm here, is there a way to choose the digital format for saved screenshots other than .png?

Hi! On the latest version Mozilla Firefox 125.0.1 when i download .docx files i get the message 'File not downloaded: Potential security risk.' I select Allow download and the file downloaded can't be opened.

Thanks!

Greetings everyone,

I've had this problem for a while and I don't know what to do.

I had a problem where Firefox kept crashing before it had finished loading up all of my former tabs and windows and so I was given the option of opening Firefox in "Safe mode" which I did, but now Firefox only starts in "Safe mode"...

I'm running the most up to date version of Firefox.

Thank you for any help!

Hey, i recently came across this post

https://support.mozilla.org/en-US/questions/1434510#:~:text=I%20view%20a%20lot%20of,viewer%20to%20black%2Fdark%20gray.

and i couldn't figure out how to do it. if anyone can tell me steps on how to do it i'll be glad.

thanks.

Every few hours, maybe 4 times a day, XULRunner appears and tabs me out of everything. It says "This profile was last used with a newer version of this application. Please create a new profile."

There isn't a 'create new profile' button. I already made a new profile as well, but it did not fix the problem.

I recently changed to the newest ESR, 115.10.0esr, to fix streaming issues.

Hi, Before Firefox's Version 125.0.1 (64-bit) latest update I could download any file from my safe office environment, behind firewalls, VPN, ... Now despite of unchecking the "Block dangerous downloads" I'm still unable to download files. I have Windows 10 on my laptop.

Here are the steps: Click on a file, Save "File not downloaded. Potential security risk." Click on the message - Allow download The result is a file with content "HTTP Status 405 – Method Not Allowed".

Please help me to work the downloading again. I am aware of the safety but I want to switch off this feature.

Thanks in advance for help, Tibor

For years, I have used print to pdf in Firefox to generate pdf files of long web pages. It always worked. But lately, I noticed that huge numbers of blank pages are inserted in the pdf file, seemingly at random. I looked at the HTML source, and could not see anything that obviously triggers the blank pages. For example, a web page that ought to print to about 35 pages generates a file of more than 600 pages, with most of them blank.

I can use Microsoft Edge as an alternative, but pdf files from that browser strip out all the color, and are nevertheless super huge, about ten times larger than the ones from Firefox. E.g. the file mentioned above, about 35 pages, would be about 1.3 MB from firefox, and 12 MB from Edge. So getting the file from Firefox would be nice.

Is there a reason why print to pdf is behaving in this strange way, and anything I can do about it?
