Firefox Community Forum

Dear Firefox Team, good morning.

I hope you are doing well and that you are all healthy.

Guys... while looking for a way to measure the performance of our site, we came across the Core Web Vitals (CWV) some time ago. These are Google KPIs for measuring the user experience on a page (https://web.dev/vitals/#core-web-vitals). Unfortunately, some of the KPIs (like the Largest Contentful Paint or Cumulative Layout Shift) are currently only accessible using Chrome and it's preformance API. That's a pity, because there are also many people using Firefox who visit our site... and it would be interesting to have such KPIs as well.

In an article by Cloudflare (https://developers.cloudflare.com/analytics/web-analytics/understanding-web-analytics/core-web-vitals/) we recently learned that Firefox is also planning to expose the metrics used in the CWV... only the "coming soon" from the article is a bit vague. That's why I'm contacting you to get some more information on that topic. Do you perhaps know whether the topic is planned and will be tackled this year?

Thank you for your attention. Best regards, Carlos

I am using Linux Mint with Firefox 127.0.2 (64-Bit)

In Preferences Applications, setting

 CSV-Dokument      to    open with firefox

opens edless new firefox Tabs - so I had to kill firefox. (setting CSV-Dokument to open with OpenOffice works fine. But this is not what I want.)

In Preferences Applications, I found further CSV types: application/csv-Typ CSV Document (application/text) CSV Document (octet/stream) CSV Document (application/x-download) Which applications should I use for them ?

I found the file "mimeTypes.rdf". However, I am not familiar with the syntax.

I've got my "homepage and new windows" setting set up with several "ext+container links so that my selected websites open in their respective containers : e.g. ext+container:name=Personal&url=https%3A%2F%2Fwww.facebook.com%2F%3Fsk%3Dh_nor

I open facebook in 2 seperate containers so that I can maintain 2 seperate personalities under facebook - e.g. I am a group admin within one, just a group member in another.

I have 2 urls defined in my "homepage and new windows" setting for these :

ext+container:name=Personal&url=https%3A%2F%2Fwww.facebook.com%2F%3Fsk%3Dh_nor ext+container:name=Facebook&url=https%3A%2F%2Fwww.facebook.com%2F%3Fsk%3Dh_nor

This was working fine without any issues. My sites opened up when I started my web browser and everything.

Recently, firefox has started up but my container tabs do not load automatically, I am getting a confirmation (I will post a screen capture as a comment).

Is there a way to turn this off and just open the tabs without a confirmation?

Okay, I give up. So, Facebook is or has implemented this Turn on two-factor authentication or whatever it is. What this means for me at the moment is that I am unable to access my Facebook account as it is now forcing me to use this Two-factor authentication thingie, despite that I do not have a mobile phone. (yes, I know it's unusual in this day of age not to have one. I did have one at one time, but for the moment I have no interest in getting another one). I would rather use my laptop anyway.

Doesn't Firefox have a Two-factor Authentication thing that I can use with Facebook? Without a mobile phone using the Firefox browser on a computer or laptop?

Now, from what I can see, Facebook is offering 3 ways of doing this. #1) Authentication app, like Google Authenticator or Duo Mobile. #2) Text message (SMS). #3) Security Key. So, because I do not use or have a mobile phone, I was guessing that my option would only be #1 Authentication app, like Google Authenticator ... which I have never used before, and while reading up on it, I keep reading that I can only use it with the Google Chrome browser?!? If that wasn't bad enough, I typically use Microsoft Outlook, not Gmail. So, I am at a loss at this point.

Again, I do not have a mobile phone. Doesn't Firefox have a Two-factor Authentication thing that I can use with Facebook? Without a mobile phone using the Firefox browser on a computer or laptop?

Help please.

i cannot print any web page from Firefox. The print option only offers me the option to save as PDF. Firefox is not detecting either my Brother laser printer or my Epson inkjet printer. if i use the print using system dialogue option fire fox shows a printer screen which has a simple entry of line prntr. If that is selected nothing at all happens. Clearly Firefox cannot detect my printers. If I save the web pages to a PDF file then open that file I can then get the normal system printing options and print the page. But all that does is clutter up my file system with files I will only ever use once. This proves the problem is clearly in Firefox and in its inability to detect system printers. I have tried all the suggestions from the help screens to no avail. Is there any other means of sorting this print problem.

Google provides a different key to differentiate installed copies of Google Chrome (standard or "Google Chrome for Work") in this file:

"/Applications/Google Chrome.app/Contents/Info.plist"

Google Chrome:
<key>KSBrandID</key>
<string>GGRM</string>

Google Chrome for Work:
<key>KSBrandID</key>
<string>GGRO</string>

Is there such an identifier on Firefox vs Firefox ESR?

Thanks, Don

Hi there, after turning on my computer in the morning, Firefox has been suddenly rendered utterly inoperable and pulls up a PR_CONNECT_RESET_ERROR for all websites. No matter what I do, including all other fixes previously suggested on the Mozilla forums and elsewhere, nothing seems to work.

Things that I've already tried and did not work include: - Pausing Kaspersky Internet Security - Resetting WiFi router - Switching to a different WiFi - Turning on troubleshooting mode - Resetting Firefox entirely - Creating a new profile - Reinstalling Firefox (several times) - Installing Firefox for Developers - Flushing DNS - Turning off proxy settings

I really don't want to be forced to use Google Chrome. Is there anything else that I can possibly do that can fix this?

Tab detachment was working fine until updating to Firefox 126. Now the tabs cannot be moved, detached or dragged to another window.

In about:config, browser.tabs.allowTabDetach is set to true

Suggestions?

Before today, my 1Password 8 password manager worked just fine with Firefox browser on Windows 11. I updated my Firefox browser to 106.0.1 (64 bits) today and all of a sudden my 1Password manager stopped filling in my usernames and passwords for me into my logins. How do I get this functionality back so my 1Password manager works with Firefox again? Is there some setting that I failed to update in Firefox? Thanks. MR

Hey all,

Last night I made the mistake of clicking a sketchy link on twitter thinking what it was some meme site( the person who tweeted is someone I know personally so I thought it was safe) once I clicked on it, I wasn’t redirected to the site so I thought it was weird then once I learned that he deleted it because it was compromised. I got scared and I was running scans through Microsoft defender. After the full scan it said that it detected Trojan:HTML/Phish!pz and the affected files where C:\Users\….\Local\Mozilla\Firefox\Profiles\cq0glqqq.default-release\cache2\entries. I deleted my cache a few hours later than I should.

So I reached out to a friend and they told me that it was probably was a false flag and I didn’t need to delete my cache. But I’m nervous that it’s an actual threat and I should do more to ensure my computer is completely safe. Also probably a lot of grammar mistakes I haven’t slept since I got this information.

There are two images here the one in green is Firefox the other in Chrome.

One of these is loading correctly and one is trashing the image layout.

It is something that Firefox is doing to the images...

CSS and or Styles tell Firefox what to do and Firefox is not doing it???

What can I do to render these in Firefox the way Chrome renders them?

106.0.2 locks up Windows Explorer (Not Responding) on my Win 7 machine as soon as it starts. After restarting Explorer, it seems to continue working. I have seen this issue reported earlier.

Any help to fix this would be much appreciated

I have tried restarting both firefox and my computer, disabled all extensions and started firefox in safe mode. When I try to right click on a firefox window from the taskbar it just disappears.

I have my computer connected to my TV so often when I open it up some windows will be on my TV which is behind my desk so its a pain to move them back without this function.

I have an iMac with Sonoma 14.3.1 with Firefox 115.9.1 esr . It is for personal use, not for a business. I just learned that there is another Firefox version (124.0.2) which is not esr....

Which version should I use and why?

If I should use the "normal" version, how do I replace the esr version with the "normal" one ?

Thanks.

I'm trying to use the built-in PDF Editor features after finding out about it but every PDF file I open with Firefox has the options grayed out (as shown in the screenshot). What should I do to re-enable the features?

Hello,

I have a Dell Windows 10 computer. I have three browsers on my compute: Mozilla Firefox, Microsoft Edge, and Google Chrome. I have an account with Clickbank.com, but I am only able to log into Clickbank using a Firefox Privacy Windows. I am not able to log into Clickbank using Firefox, Edge, or Chrome, only in the Privacy Window. I do have Malwarebytes browser guard on my computer, but I have it turned off when trying to log into Clickbank.

Does anyone know why this is happening?

Thank you.

I expect the back button to return to the previous page visited, but too often the button either doesn't respond at all or a right click is required to view the page history. Is there something I need to do get the original function of the back button that I thought was universal in most browsers?

My computer (Windows 11) crashed while I was using Firefox--for the first time that I've seen, it did a full disk check. When booting back up, I was unable to use Firefox, since it said that my profiles.ini file was lost/corrupted.

After renaming the old file, I went back to the folder. It was easy enough to reinstall the add-ons that I needed, but I'm trying to get my bookmarks back. However, I can't seem to find them--the "bookmarkbackups" folders that come up are too new, and only one (the current one) has a file in it.

Any help will be appreciated! I'm not sure what I can do.

I have been working for Data Annotation for nearly a month and never got this error before. I need this money for rent! I'm trying really hard not to freak out here but today is the deadline for rent and the only way I'll get that money is to log on to this website so I need help and I need it now.
