Lately I am noticing my browser takes a very long time to load certain websites (GitHub and Confluence mainly)

I don't experience the same issue on Google Chrome

When sites do load, they are often without stylesheets, and page elements do not work (possibly indicating scripts are not loading)

There are two pdf files attached to an email I received. When selecting view all and then save all, one file gets saved with the name of the other file, and a zero byte file is created with correct name. The other file is not saved. This erroneous behaviour is repeatable.

Ok so a month ago FF updated on four W11 laptops and now every time since then when you open FF it wants to make changes to your HDD and then tells you it can't download the latest version. I've uninstalled it and reinstalled it and its the same across all devices. None of the three devices are running any of the same software aside from the OS as they're all dedicated to different purposes, so I know its not something on the devices themselves. We ended up uninstalling it on everything aside from the older W10 desktop because its a constant nuisance. Each time it updates it is successful and there's no failure messages, so it's not like its obviously failing to update, but something certainly broke.

Although I have my Bookmarks Toolbar set to "Always Show," none of the bookmarks are visible (and therefore, they're not functional, either). I have tried refreshing Firefox (it just hangs on "almost done") and downloaded /reinstalled the application. I have no idea what to try next (Mac Desktop).

I'm trying to get the Enterprise Release Notes for Firefox 148 and 149. They seem to be the only ones missing from 141 to 151 inclusive. It appears the URL for the notes is in the format https://support.mozilla.org/en-US/kb/firefox-enterprise-###-release-notes/, where ### is the version. For these two versions, I get a "Page Not Found" error.

I have tried finding them through the Firefox Release Calendar (https://whattrainisitnow.com/calendar/). If you click on the link to expand previous releases and then click on a release version number, the page that comes up has links to the three different versions of release notes. Enterprise shows a link for the two missing versions in the same format as I have noted above.

I have also tried https://support.mozilla.org/en-US/products/firefox-enterprise/whats-new-firefox-enterprise and it lists quite a few versions but 148 and 149 are missing in action.

CDNsearch engine becomes my Mozilla search most times itself without my permission . each time i change it to Google search engine but again when i open Mozilla after a while i see CDNsearch engine at first page of my Mozilla. how can i delete it permanently ?

Since the Firefox update to 152.0 64bit I have noticed that it takes two attempts to log into Spectrum email. The first time I try I get a IDID-4000 error (see below image) after entering my sign on and password. I then have to retry by selecting the bookmark again and then after entering my sign on and password a second time I can get in. This does not happen in Edge browser. I have tried deleting my sign on and password in my saved passwords in Firefox and then manually reenter my sign on and password at the prompt for Spectrum and then saving it again but it keeps happening. I have also tried turning off enhanced tracking, clearing cookies and site data, refreshing Firefox and stopping my Norton 360 and it still happens. There must be a bug in the new Firefox update 152.0 that is effecting the ability to sign into Spectrum as this was not happening before. I am wondering if anyone else is seeing this problem and is there a solution to fix this. Should I file a Bug Report about this? We should not have to jump through hoops or do some work arounds to try and get things to work like before as I have read with other questions having problems with 152.0 update. This update needs to be fixed.

Respectfully,

The SSL cert has been installed by the entity (Gridhost) from whom I have bought it for 20 years. And as explained, Firefox still shows it as Not Secure while Chrome say it is secure.

Over the last week or so, I call up Thunderbird then when I click on anything, it just comes back "Not responding" Any ideas?

Thanks in advance Tony Sneath

Mail.com support recommended that I install Thunderbird to clean out my inbox. Things went perfectly and I managed to delete 20,000. Then the app just STOPPED. It wouldn't delete any more. I emptied my email's trash, restarted my phone twice, and cleared the cache several times. The app is just inoperable.

Please help! I have 265,000 more emails to delete.

I invoke Face Book but it FB page asks me to log in. Will not accept my user and password. Also You Tube is unstable. Only when in Firefox. Other browsers are OK, I can go straight in to site on other browsers.

Need help please to fix this problem: Firefox does not open QR codes on my iPhone. On my phone, the toggle for Scan QR codes is turned on. I open the camera on my phone, point it to a QR code on my laptop screen, Firefox on my phone opens in a new screen -- but nothing happens. What is missing? Thanks for helping me.

I have three separate Yahoo email accounts. I set up Thunderbird to link to each Yahoo email account separately. It worked fine for a year or more. On 5/25/26 one of the three Thunderbird email accounts stopped downloading emails from Yahoo. I could see at the bottom bar Thunderbird indicating that is was downloading 1 of XX emails, but never actually downloads them. There is no error message. I checked the Yahoo email account to verify the number of emails I am missing from Thunderbird and the number is correct. I can see the emails in Yahoo. I'm the only person using Thunderbird, so no changes have been made to previous settings for retrieval. I confirmed Security and server settings for Thunderbird in and out going emails, and Yahoo are correct. I tested the connection in Thunderbird, and the connection is successful. I tried to send an email from the Thunderbird account having issues, and the email was sent and received by the recipient. The recipient replied, and Yahoo received the email, but failed to download it to Thunderbird...along with all the other emails since 5/25/26. I unlinked the account and reestablished the link between Yahoo and Thunderbird, and still not fixed. I tried restarting the computer, with no change. I tried to send an email from Thunderbird to one of the other Thunderbird emails and it was sent and received. I made changes to Thunderbird to force the download of emails, and it still wouldn't do it. I turned off my antivirus, closed Thunderbird, and restarted it, and that didn't change anything. The capacity of emails on the email in question only has 739 emails, so it's not over the limit and I have plenty of storage capacity. Thunderbird is set to save emails, Cookies and cache were cleared, no change. I ran the folder repair feature in Thunderbird, but there was no change. I compared all the settings between the other Thunderbird emails that are working against the one that isn't, and they are all the same. There was a suggestion to close out of Thunderbird and delete the "Global-message-db.sqite" file from the Thunderbird profile in case it was corrupted, and it would recreate this file when Thunderbird was restarted. The file was recreated, but it didn't fix the problem. There was mention that a suspicious email in Yahoo might be blocked by Thunderbird, so I placed various emails in the spam folder, and it didn't work. I did find one email in the Yahoo spam folder that was dated before 5/25/26 and moved it to the Yahoo inbox. Lo and behold, that one email downloaded to Thunderbird. So there is something within Thunderbird preventing emails from downloading after 5/25/26. I've read many people complain about similar download failures with no solid fix. Someone mentioned it fixed itself on a day, but then stopped again days later. Someone else mentioned Yahoo changed its password protocol to transfer emails, but that doesn't make sense since the other two are still downloading based on the "old" password protocol. I'm at wits' end. Thanks for reading all of this. I hope someone has a solution.

I'm running Firefox on Win10 with no options to upgrade to 11. Since the latest firefox update installed, I'm getting a screen that says "Oops, something's wrong," and then I'm kicked out of gmail. A screen asks about sending a report to Firefox, which I check OK for. Today this is happening about every minute to 30 seconds . What needs to happen?

I have always, for 15+ years, been able to use the system Print dialog box to create a PDF.

But as of updating Firefox to version 152.0 (aarch64), all buttons related to Saving a PDF, etc. send the document straight to the Printer to print a hard copy. There no longer appears to be any way to save a PDF.

Example scenario: 1.) Visit website 2.) Select Print (cmd-P, File > Print) and open the 1st print dialog box 3.) Select "Print using the system dialog..." 4.) Select PDF in the 2nd dialog box. 5.) You used to be able to save the PDF at this stage, opening Finder, naming the file, and choose the Save DIR. However, as of this latest update, even after the Finder File Name dialog box, hitting Save at that stage sends it to the printer to print a hard copy.

Pressing PDF, Save as PDF, Open in Preview, and Save as Adobe PDF all send the file directly to the Printer to save it.

I've got tons of receipts and things to save for work in PDF and FF was always great at this. What happened? Is this a feature or a bug? Any and all advice is welcomed.
