Firefox Community Forum

Hi We switched to W11 today. My bookmarks have transferred to the new system but on my wife’s ‘side’ of the computer they have not. How do I get her bookmarks back please? We each have our own email address so we have two Accounts. Thank you.

Hello For some reason most of the buttons in my toolbar have stopped working. When I first open Firefox they all work, then when I enter websites they stop working. The 'home' button still seems to work, but almost all others (such as the 'back' button etc) can't be selected. This is very frustrating. To note, I am not tech savvy at all.

Thank you in advance for your help.

I'm on MacOS 15.6, and FFox 142. My company recently rolled out "PSSO" for Mac users, and it works pretty well on non-Microsoft sites. However, when accessing resources behind MS Azure/Entra, such as outlook.com, sharepoint, even github, we get the following error from "login.microsoftonliine.com":

You can't get there from here Your sign-in was successful, but you can't open this resource from this web browser. You might be able to access it from the Safari browser (ask your IT department for a list of approved mobile and desktop applications).

All of these worked fine before PSSO while using Yubikeys (in fact I plan to revert to Yubikey next week).

The IT department says that Mozilla needs to implement this, referencing the "only applies on Windows" statement shown on https://support.mozilla.org/en-US/kb/windows-sso . They (and I) have demonstrated that it also works just as intended on Chrome and Edge browsers.

And yet, we see that "Microsoft SSO" was added in FFox 132: https://bugzilla.mozilla.org/show_bug.cgi?id=1768724

Who needs to do what to make this work on Microsoft web-apps?

I’m the owner of a Korean webtoon platform at https://newtoki.com.co/, and I’ve recently run into a strange, intermittent issue that only seems to happen in Firefox.

Here’s the situation:

The site loads fine most of the time, but occasionally when I (or some of my users) try to open it, Firefox throws a “Secure Connection Failed” message with an error code like SEC_ERROR_OCSP_INVALID_SIGNING_CERT or sometimes NS_ERROR_NET_RESET.

This happens randomly — sometimes on the homepage, sometimes when navigating to a category or content page.

I’ve tested in Chrome and Edge, and the site loads without any errors there.

Steps I’ve taken so far:

Cleared Firefox cache and cookies, restarted the browser — no change.

Tried in Firefox’s Troubleshoot Mode — still happens occasionally.

Contacted my hosting provider — they checked the server logs and SSL configuration and told me everything is fine on their side.

Verified my SSL certificate chain with an online checker — no obvious issues found.

Additional details:

I’m based in Korea and use the site daily for uploading and managing content.

Some users outside Korea have also reported the same error, but not consistently.

The issue started about a week ago, without any major changes to the site’s code or hosting environment.

I’m wondering if this could be related to Firefox’s OCSP stapling checks, a caching issue, or something about how my CDN is serving resources.

Has anyone seen similar behavior in Firefox with otherwise valid HTTPS sites? Any suggestions on what I can check next would be greatly appreciated.

Thank you in advance for your help!

Hello,

I have noticed that my CPU runs hotter when playing videos in Mozilla Firefox, for example streaming TV series. Youtube seems to be less affected.

My configuration is:

CPU AMD Ryzen 9 9950X3D (16C/32T, up to 5.7 GHz, 128 MB, AM5) MBO Gigabyte X870E Aorus Elite WiFi7, AMD AM5, WiFi, Bluetooth, ATX RAM G.Skill Trident Z5 NEO RGB AMD Expo, 64 GB (2x32), DDR5 6000 MHz, CL30 SSD Samsung 9100 Pro, 2 TB, M.2 NVMe PCIe Gen5, R14700/W13300 GFX Gigabyte AMD Radeon RX9070XT Aorus Elite OC, 16 GB GDDR6 PSU Be QUIET!

The normal CPU temperature was around 47 c (sometimes even 46 c), but it now goes up to 52-53 c. If I disable hardware acceleration, it goes up to 59 c. If I switch tabs to another that only has static content, the temperature drops.

Additionally, when doing the same thing in Google Chrome, the temperature is perfectly normal.

Is there any way to fix this?

Thank you in advance!

It drives me crazy that when Firefox updates, it requires me to enter my system password to install a mysterious, always unnamed add-on. I know it does this, and it's been going on for years, and I hate it. I never want to enter my system password to install something that is unknown. Since the add-on is never identified, well, it could be something beneficial, or it could be some new malicious package that snuck into the update process. How am I supposed to know? To me, it's unacceptable that Firefox keeps doing this. (Maybe it's MacOS's fault, but this doesn't happen with any other non-Apple software package. So it's Firefox's fault as far as I'm concerned.) I've been using Firefox for decades--since it was Netscape. I don't to use any other browser except for special cases. But I'm thinking of switching over to using Safari all of the time. Not that it would harms Firefox or anyone involved in developing it if I switched. But switching to Safari now would be a p.i.t.a., so it shows how much this install bug annoys me. (Years ago I submitted some kind of bug report in the bug system, but that's a pain. It's an opaque bug reporting system for anyone outside of the Firefox developer community.) Well,that's it. Lovin' Firefox except for this feature.

Hello again. Re my very recent post about a game on facebook functioning very slowly after the latest update, I now discover a worse problem with a word-game on a different site that I have also played for years on Firefox. Basically, after the new update, I find that I am no longer allowed to complete a move. Given the now 2 problematic situations I have, do I now with great reluctance have to abandon Firefox?

The new update refuse to load youtube, MeWe etc. It says "Cannot do this offline".

managed to get here so I'm not offline. How do I uninstall the latest update?

On my Macbook I have four accounts. I loaded Firefox via one of them. I do not want Firefox running or its 'background processes' in the other accounts as I do not use it there. If I switch account from the one in which I use Firefox to another does Firefox keep running processes?

i am a new user of firefox and selected it to securely access some websites. I followed the instructions to set firefox as my default browser but the search bar still says" search with google or enter address " and it shows google as the web browser , When i click the dropdown menu firefox is not an option . How do i set this so firefox is the browser ? i am using windows 11 .Thanks in advance.

I have recently found out that i couldn't add my Avast Antitrack to the system. On querying this with Avast they tell me that Firefox will no longer use this add on. I really want to know why this can no longer be used on Fire fox please.

Up until recently Bing Maps in the UK has the option to display Ordnance Suvey Maps and the function to measure distance.

Now, using Firefox, Bing Maps display a Beta version with very limited functionality. Using Microsoft Edge, Bing Maps have all the functionality that I expect.

Has something changed within Firefox that has caused this problem? Is there something that can be done to allow Bing Maps to work correctly from within Firefox?

Hi - After the latest Firefox update on my laptop around 2 days ago, I am now unable to play a game on facebook that i've been playing with no probs on Firefox for years. After this update, this game of all things (nothing else is) is slowing Firefox down. Now the page fully loads very slowly - as do the moves I try to make. Am I correct in thinking that there is basically no option to safely return to the previous version? If so, why at the very least was I not given the option not to update, while acknowledging I may be at greater risk if making such a choice. Looking forward to some help please! Thank you Steve

I've used Firefox for years and have been very happy with it. Recently, however, it will not open no matter what I do. I've refreshed it, removed and reinstalled it, but it still will not open. What could be the problem?
