When I add certificate exceptions, such as for my router's self-signed certificate, Firefox forgets the exception at seemingly random intervals. Often this happens in several days. In one case it was overnight. This has been going since at least early 2023, probably a year.

In noticed Firefox also forgets settings like "allow popups" set on a site (like on Gmail for example), but not necessarily at the same time as certificate exceptions are forgotten. Other settings don't seem to be changed or forgotten.

These problems occur on different Macs using the same Mozilla account. Refreshing Firefox has made no difference.

Hello volunteers -- I downloaded Thunderbird to a newer iMac. The Input messages and folders from my laptop appeared fine, but the addresses look like they are from Contacts rather than the laptop Address Book, i.e., names, phone numbers and postal addresses, but not email addresses. The first image (screenshot from an Apple laptop) is what I want; the second is what I got on the iMac. Is someone able to help me with this? Thanks very much, Susan

Hello, I've followed Firefox's invitation to install and update the browser on my Mac. Unfortunately the new version is not compatible with OS 10 El Capitan, my operating system, so now I can't use Firefox at all. How I do get the old version back?

Thank you, Lars

I have been unable to use Firefox for Gmail for several years now. I use Chrome instead, because whenever I try it on Firefox, I get the following message: Do you really want to use HTML Gmail? You're about to use a version of Gmail designed for slower connections and legacy browsers. To get all of Gmail's features, including inbox categories, images and quick actions, please use the latest version of Gmail (recommended). When I click on the box marked Take me to the latest version, absolutely nothing happens. If I click on the box for the HTML version, Gmail appears, but devoid of anything resembling Gmail as we know it now. Much as I want to use Firefox for everything, I can't, because this is a serious limitation. Am I alone with this problem? It has happened on two different laptops (Macbooks).

I've been using Firefox for iOS for several years and know how to use it at a basic level.

Just in the last couple of weeks, it doesn't want to open any buttons. That means if I want to write an email and add an attachment, or I want to post a listing on my Etsy shop and click on 'Add Photos', I click, and nothing happens. Just below this box, in fact, is 'Add images (optional):' and then a button that says 'Browse...'. Nothing happens when I click this button. There's no notification saying pop ups are blocked, just nothing happens.

So I find myself having to close down Firefox and go to Chrome or Safari, over and over again – it's so annoying, because all my passwords are saved on Firefox, so I'm just flicking between them all the time!

Any reasons you can think of? It seems to be up to date? Version is 119.0.1 (64-bit). Thanks!

On my phone, both passwords from Firefox and iCloud auto fill into my browser, but on Mac I do not see anything besides the Firefox ones. I keep my most up-to-date passwords in iCloud, but would love to use auto fill in Firefox as I am not a fan of Safari. Is there a way to set this up?

On Mac OS 14.4 Firefox hangs on launch and crashes, requiring "Force Quit" when I try to Refresh or Troubleshoot. Uninstalled and reinstalled multiple times, and restarted computer several times. Have spent several hours trying multiple community suggestions to now avail.

I am not a programmer, but am able to follow instructions. I clearly need someone to hold my hand and walk me through the solution. (I even checked out the Kaspersky suggestion, but cannot install it because Firefox cannot connect to the Internet.)

I have downloaded and saved "Raw Data.docx" and "Application Basics tex.docx" from one of the crash reports.

P.S. On this question form Firefox guessed that my operation system was Mac OS x 10_15_7, but it is 14.4

I've been a faithful Thunderbird user since the beginning - and continue to use Thunderbird with our company's Microsoft365 deployment

until Monday of this week -- when suddenly I find that my credentials are being refused.

The symptoms

• XXX: Connected to outlook.office365.com
• nothing in the activity viewer
• no email coming in

I've read and tried all the fixes proposed in the article at https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202 (restarting thunderbird after each step, naturally)

• have authorized Thunderbird to our Microsoft365 tenant
• created and tried registering with a new thunderbird profile
• have set my security settings to 'accept all cookies'
• have used the config editor to remove 'oauth2.issuer' and 'oauth2.scope' values
• I've checked that my account in Microsoft365 has IMAP and Authenticated SMTP enabled

So, since Monday, I've been living in hell, trying to pretend that the Microsoft Outlook app for macOS is useable, but it's practically debilitating to be forced to use that piece of software.

Can somebody please point me to another possible set of steps that I can use to try and diagnose this?

I absolutely hate myself for having to ask for help on this, but I'm at my wit's end...

Hi all, I have an Adobe account and regularly use Adobe e-sign to send out contracts. I have recently updated Firefox and since then, when I try and send out PDFs for e-sign via Adobe Acrobat Reader, it doesn't get past the upload of the document stage. When I do it on the web browser, I can log in to my account fine, but as soon as I try and view the PDF I want to send for signature, it tells me that:

'The cookie functionality is disabled on your browser

Adobe Acrobat Sign has detected that the cookie functionality is disabled on your browser. To use Adobe Acrobat Sign, please enable cookies on your browser.

When cookies are enabled, click the 'Continue' button below to proceed to Adobe Acrobat Sign. Instructions for enabling cookies Safari for iOS Safari for Mac Chrome for phone or tablet Chrome for desktop OS Firefox

   Click on the Firefox menu.
   Select Preferences.
   Select the Privacy & Security panel.
   Select Standard to enable cookies.
   Set Accept third-party cookies to Always to enable third-party cookies.'

I have followed all the above but it doesn't make any difference. I have also turned off Enhanced Tracking Protection for that site and it worked once, but then stopped working again.

I'm on a MacBook Pro.

Thanks so much for any help!

/edit: moved thread from Firefox for iOS (for iPhone/iPad) to Firefox section as you have macOS

Hello

Hoping someone can help me with this asap.

I was prompted to update firefox on my mac laptop.

So I did the update by clicking the button available at the top of the firefox browser, but now I can not open Firefox at all.

When I click on the firefox icon it does not open firefox and this message appears: You can't use this version of the application "Firefox with the version of OS X. You have OS X 10.11.6 . The application requires OS X 10.12 or later.

I understand what this means but not sure how to revert back to the previous version of firefox.

When installing the new update/version of firefox, i have deleted the old version of firefox.

I am following these instructions currently to try to resolve it: https://www.wikihow.com/Downgrade-Firefox

Following the instructions above I went to: https://ftp.mozilla.org/pub/firefox/releases/ , but can not find the previous version of firefox that I need.

The only info I have on firefox is version 102.2.0. I am after the version before this as assume that is the one compatable with my laptop currently (i can not update the OS ).

Can you help me download the previous version so it is compatable with my mac laptop?

Thanks for your help in advance

Hi, none of the virtual meeting applications (googlemeet, teams, etc.) are working on my firefox last version for OSX. The same in troubleshut mode. But it's fine on my Mac using Safari. I'm convinced that there is some configuration I touched in the last year as before I don't had this problem.

Can someone help me?

Thanks,

When I select "Add Bookmark" from the Bookmark dropdown menu on the menu bar, the popup menu to select the location (folder) to place the bookmark quickly flashes open and closed. The bookmark is created, but it is created in the last place that a bookmark was added. If I am still on that tab and I try to use "Edit Bookmark" from the menu bar to open the pop up it also just flashes up and closes.

If I move away from that tab to another one, and then come back to it, the "Edit Bookmark is not even listed as an option."

Can you please assist.

/edit: moved thread from Firefox for iOS (for iPhone/iPad) to Firefox section as you have macOS<b/b>.

Three days ago Firefox froze and wouldn't allow me to do anything. I quit and then Firefox would not open. Went back to Safari and download the latest version of Firefox, and installed it. It started by saying that Firefox was already running (it wasn't) so I forced it to quit. Installed and asked it to replace the existing version. Then I tried to run it and it told me that it was already running!!!

Short of deleting the whole application and starting again - losing bookmarks, passwords, etc. - what else can I do?

/edit: moved thread from Firefox for iOS (for iPhone/iPad) to Firefox as this both sounds like desktop version and you put in "Mac Ventura v13" in system details on right so you have macOS.

Latest upgrade to MACOS Firefox (using MAC OS 10.15.7 Catalina and Firefox 118.0.2) will not show comments section on Wall Street Journal's Editorial or Commentary articles. Safari and MS Edge will. I have checked preferences and do not see any settings that have changed. Any suggestions?

/edit: moved thread from Firefox for iOS (for iPhone/iPad) to Firefox section as you have macOS.

I wanted to upgrade and update my Firefox to the latest version. Encountered some errors so I uninstalled the old version and reinstalled Firefox' latest version. Now all of a sudden all my Add-ons / Plugins / Extentions on the latest version of Firefox for Mac OS is gone...

Microsoft Excel is no longer listed i Applications as download option. All files downloaded automatically are stored as Microsoft Word files, not just excel files. I can change individual files manually to .xlsx which is a nuisance, but this also happens with Zip files (7Zip) and I am at a loss as to how to change them when they are downloaded as a Word document.

This does not happen on a newer MacBook Pro, but I need it to work with the older version. The older Mac is MacBook Pro 9.2 with MacOS Catalina Version 10.15.7 Firefox is version 103.0

I have been using Firefox for many years and I know how to use it well. However, I am currently experiencing an issue with the text and fonts on various websites, including Facebook. Even after refreshing and attempting to troubleshoot, the issue persists.

I have noticed that the font and text work normally in Firefox's troubleshooting off mode. I have even attached a photo of the issue for reference.

Please advise.

I have lost my "home" icon so have to close and reopen or check history to go to my start page. Also, I can't play You Tube videos at the moment. The little house icon is missing. See screen shot.

Whenever I try to sign into Outlook Webmail (https://outlook.office.com/), Firefox crashes. I am on a MacOS Monteray (12.2.1). I have cleared all Firefox caches and cookies. I have completely uninstalled and re-installed Firefox. I have run it with my usual extensions, and completely clean, without any extensions and just the default settings.

The initial login page loads fine, and I type in the email address associated with the account. This takes me to the password page. If I type in an incorrect password, the site tells me so immediately. If I type the correct password, Firefox crashes--I get the spinning beachball cursor and (application not responding) in the dock. My only recourse is to force-quit Firefox.

Outlook webmail used to work fine in Firefox--I used it on this very machine nearly every day. The only change was that I recently had to update my email password. But again, I have had to do that every three months for years and have never had any problems.

Outlook webmail works just fine on this machine in Safari and Chrome. It's only Firefox that has any problems with it.

Any ideas about how to fix this would be greatly appreciated.
