Firefox Community Forum

Hello ,

This is my first time to ask for help or have a question. I have a program that finds Super-Cookies that are not

deleted by normal means. HSTS is another word for them. This one is owner@realserv.com which can redirect your browser and is mainly to spread adds: It can also read info on your computer;however I am having no problems from it that I know of and have discussed it with others that say it is not malicious and is in fact a Microsoft file. In any case I have found a site to offers a way to remove it.

https://sensorstechforum.com/realsrv-virus/#what-is-realsrv-

I only use Firefox but in following the directions given I was unable to remove it. The page was probably written before all the changes to Firefox.

Can you advise on this subject? Firefox is latest version.

Thanks Paul

For last few weeks something keeps changing my default browser from DuckDuckGo to Amazon and I have no idea how or why. Is there a way to lock the default so Amazon can't change it?

I have set up a fresh install of Ubuntu 22.04 and logged into Firefox. However it didn't sync my extensions and if I try to access addons.mozilla.org, I get a MOZILLA_PKIX_ERROR_KEY_PINNING_FAILURE error (screenshot attached).

This did not happen, when I did the same thing with a fresh Windows installation 2 hours earlier (I set up a dualboot system). I already tried logging out and in again and removing SiteSecurityServiceState.txt and ~/.mozilla, as well as emptying cache and deleting cookies without success.

I recently wanted to switch to using Firefox passwords from LastPass. I imported my passwords from LastPass into Firefox Browser on my personal Laptop. I have enabled password sync, besides all other things. Yet the passwords do not seem to be syncing. I have been trying multiple things since yesterday, but nothing seems to fix the issue, like logging out and logging back in, trying to manually sync etc. This seems like a bug to me.

I wanted to start using Firefix passwords on my Android device as well, but this issue is making it difficult for me. Please look into this issue asap.

It seems like almost every time I do a Windows Update on and sometimes when I just restart my Lenovo IdeaPad 3 my language gets changed from American English to French. Even some of the add-ons change preferences. Since I don't speak or read French it can be a real hassle to get everything changed back. What I usually end up doing is going to the page on the Mozilla site that has different downloads for different languages and I download the correct one. Once I install it over the existing installation things go back as they should be until I do another Windows Update or like I said before, sometimes after just a restart. This just happened again a few hours ago when I did a Windows Update. All the menu items and drop downs were suddenly in French. My Forecast Fox changed to Celsius instead of Fahrenheit. My Notifier for GMail changed to French. A couple log in pages for some web pages were in French. This never happened with other laptops I have had that were different brands. I once tried just uninstalling Firefox and then reinstalling the correct language version and things were fine until the next time I did an update. My preferences are set to how I want them and I just don't understand why it keeps getting changed.

How do I uninstall the Firefox icon from the taskbar? The standard article on the Firefox Support website is `How to pin and unpin Firefox from the taskbar on Windows 10 and Windows 11', but it seems to be out of date. It says to right-click on the icon and click on `Unpin from taskbar', but there is no such item in the right-click menu any more.

I know that it became difficult to unpin the Firefox icon about a year ago. I got a new PC recently and installed Firefox, but I could not remove the icon. Then realised that I should have done this during installation, by using 'Custom installation' and unticking the 'Icon on taskbar' option. I searched the web for clues and found none, so I uninstalled and reinstalled, which was a nuisance.

Some months later, I have just installed the new version 110.0.1, but I forgot to use 'Custom install', with the result that the icon is back on the taskbar. Again I have searched the web, and again no success. I tried reinstalling V110.0.1 on top, using 'custom install' this time --- I could switch off the 'Icon on taskbar', but the icon is still there.

I don't want to uninstall-reinstall this time because I have now configured Firefox as I want it, so that would waste a lot of time --- and I will probably forget again sometime in the future.

I am sure that Firefox has not done this deliberately, because they are always so much on the user's side.

QUESTION: How do I unpin the Firefox icon from the taskbar without uninstalling? I have an idea that there is a registry hack that will achieve this.

bold textwhy has my browser decided that my searches should be done in the address bar. I never do searches from the address bar. please change that or tell me how to go back to searching in the search bar instead of the address bar

If I click on any "mailto" link the only options are Gmail or Firefox.

If I go into Settings and choose applications then content type: mailto the same options are there- nothing for Yahoo Mail.

It used to be there, now it has gone.

Using version 110.0.1

Is there any way to manually add Yahoo mail to Firefox?

After a recent reinstall Firefox seems to have a problem. This seems to be only Firefox specific and I can't find a working solution online after googling.

Youtube videos work, although they do give errors sometimes. A refresh always fixes those. However Twitch/Youtube live streams do not, and display a generic error message. When trying other browsers the live streams work fine.

And old Bugzilla post (https://bugzilla.mozilla.org/show_bug.cgi?id=1467495) describes what I believe to be a possible reason for the problem, however following the solutions in that thread have not yet lead to a solution.

Any further insight or solutions would be appreciated.

Firefox was working like a charm on my MacBook Pro '16 19 with Venture 13.0 macOS, without any issues. But somehow, after I did upgrade to Venture 13.2.1, Firefox started random hangs/freezes after each 30-60sec. And it takes ~5-10sec. I started to get random panics 2-3 per day.

I did not changed anything in the settings. This also happens in Private Window mode. I usually restart the computer everyday. (Eventually a new Firefox instance each new day, before Ventura 13.0 and still do after upgrade)

I have read the followings:

• https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode
• https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-settings

But didn't help me. I have everything (tabs, favs, extensions, works, etc.) so that I do NOT want to reset/refresh ANYthing. I'd prefer to fix the root cause and understand the issue why it keeps occur.

I either change my main Firefox browser (after 8+ years) or look for a solution to fix the root cause without doing any refresh or reset (or something that cause data lost).

Is this a known issue?

Could you please help me on this? Thanks!

My Environment:

• Firefox 110.0
• macOS 13.2.1

Also, in the Troubleshooting Information section below, browser somehow couldn't collect to data and showed a "manual way documentation" button. I clicked it and it redirected me a doc. When I back to previous page, I lost the data I've just written here. So had to rewrite everything... Can you please fix this?

Windows 11 x64, Firefox 110.0.1. HTTPS-only mode disables. OCSP enabled. I've tried playing around with these flags, nothing works.

• security.certerrors.mitm.auto_enable_enterprise_roots
• security.certerrors.mitm.priming.enabled
• security.ssl.enable_ocsp_stapling
• security.insecure_field_warning.contextual.enabled
• security.certerrors.permanentOverride
• network.stricttransportsecurity.preloadlist
• security.enterprise_roots.enabled

Do not recommend me to click Advanced -> Accept the Risk and Continue. I want to disable the warning forever for all the hosts. For example, Chrome supports flag --ignore-certificate-errors, I need something like this.

Hi, I have been wanting to switch to Firefox for a while now and I have imported all of my data from Chrome onto Firefox. All the other members of my household use Firefox on their Mac laptops and iPhones. I have only ever signed into my own account on Firefox, and in the same way I have only ever signed into my own account on Mozilla VPN, which I have used for over a year while living elsewhere and have never had a problem with this. I also have only my own Google account in the data imported from Chrome. I have no one else's information for any account on anything in my device nor, to my knowledge, do they have any account information of mine on theirs. However, sometime in the 10 or so months since I imported my Chrome data - around the same time I moved into a house with others who use Firefox - my laptop's Firefox seems to have...connected somehow, in a way atypical with normal syncing, with the other devices in my house. Occasionally, when I open Firefox on my computer, whatever tab another household member has open on their computer will open instead of a homepage. Also, a little icon pops up occasionally to tell me Firefox is "open on iPhone" when another household member is using Firefox on their iPhone. I use an Android which does not have Firefox installed, so it's not a glitch syncing with my own device. I do not know how this happened and I do not know how to stop it. There doesn't seem to be any evidence of this connection in any place I can see in the preferences window, nor can I find any way to permanently unsync my device's Firefox application from anything unless I sync something first. Any ideas? I'm not that terrible with computers lol, I swear!

I've noticed that while on Wi-Fi, having Firefox open on any webpage will cause consistent ping spikes every 5 seconds, making online games unplayable.

I've tested this normally, tried disabling all extensions, and tried troubleshoot mode. Task manager does not show any changes with CPU/Memory/Disk/Network under Firefox's process when these ping spikes happen, but the issue goes away immediately every time after closing out Firefox.

The webpage and what you are doing on that webpage does not matter (like streaming YouTube), it even happens after visiting google.com. However, I'll rarely get lucky and this issue won't occur while Firefox is open.

Issue does not occur with other browsers. If there is any additional info that I should provide please let me know.

Hi. I have about 15 home pages set to open when I open Firefox. I read the news, catch up on a few sites and have various jobs and tasks to complete. But whenn I've don all that, and close down Firefox, each time I open Firefox again to search for something etc, all 15 of my startup pages open up and I have to manually close them all down.

On Windows 11, all I need to do it right click the firefox icon and select open new tab. This is great, it opens Firefox with just a single new tab open. But on my iMac, this option is missing.

How can I re-open firefox with just a blank tab - or even just one specific page like Google?

I currently use Chrome on Android & Chromebook as my main browser, but I would like to switch to using Firefox now across all my devices (linux, android, chromebook). To do this, I need to import my passwords from Chrome to Firefox, and have them sync between the Firefoxes on all of my devices, but it's not working. I have tried the following:

Method 1: I installed Chrome on my new Linux machine. Checked and made sure it had synced my passwords by logging into a website using Chrome. Then, on Firefox, I pressed alt to enable the toolbar, then File->Import from another browser. The pop-up says "No programs that contain bookmarks, history, or password data could be found."

Method 2: Chrome seems to have a feature to export the passwords to csv. So I exported the passwords from Chrome to a csv on Linux. To be thorough (because I am having trouble getting this to work), I used accounts.firefox.com to sign out the Firefox on my android phone and chromebook, then (on the phone) I deleted my browsing data, uninstalled firefox, and rebooted the phone. Back on Linux, I did about:config, then set signon.management.page.fileImport.enabled to true, then did about:logins then menu->"import from a file", selected the csv that I just exported from Chrome, and clicked Import. Import Complete, 332 logins added, 1 not added because it was missing a password. Logins successfully imported, hooray! For testing purposes, I create a unique new password entry, http://foo.com username "a" password "b". Then I go to about:preferences, make sure that syncing is on and I'm currently syncing logins and passwords, and press "sync now". Log in to my phone, install Firefox from the play store, start it up, sign in using my email and password (it says "syncing"), go to logins and passwords, click "saved logins". The only one listed is for foo.com, the fake one I created to test the syncing, but I expected to see all 333 there.

How do I get this to work?

bold textFirefox has become a HUGE memory hog, and every update makes it worse. Would it be POSSIBLE for mozilla firefox to ACTUALLY listen? Instead of ASSUMING you already know EVERYTHING, pay attention to your users.........MOZILLA FIREFOX, WILL USE UP ALL MEMORY(IDLING). There are several THOUSANDS of posts stating that mozilla firefox is a HUGE memory HOG, and of course the people of firefox can NEVER be BOTHERED to listen to the public.

  That is the problem, we are left without the slightest bit of help or service when mozilla decides to intentionally ruin our PC's. And absolutely no one will believe us when it's been stated THOUSANDS of times that mozilla firefox uses up ALL memory(on the net).
   Please do something, we the public are getting FED-UP, with a corporation that "just can't be bothered to ever help anyone". Hint: the incessant updates do more to make the users angry, than "improve a browsing experience". I'm seeing 500mgs and 12 windows forced open just to idle firefox, and this is directly after the update.  email address: jimerb6@yahoo.com. Please explain away how it's all my fault, or my computer, or the net provider, this is wildly out of control. I await the least bit of offered help or service.

Hello there,

I've been having problems with using Firefox for a while. For context, I'm using a computer given to me by my college because my personal laptop gave up the ghost a while ago. It has a lot of security programs installed on it and I am obviously not allowed to mess with those at all, as my account doesn't have the permissions. Here are some of the problems I've been having:

• always signed out of my firefox account on relaunch (no options enabled that would cause this)
• always logged out of specific websites on relaunch (primarily noticed with discord)
• addon windows never load
• addons don't work, even when enabled, and after uninstall and reinstalling

I've tried uninstalling and reinstalling Firefox also, but nothing seemed to fix these problems. The only thing that stopped happening was being signed out of my Firefox account on relaunch but I have no idea what was causing it or what stopped it.

Now, in an attempt to fix the problems I was having with addons, I refreshed my Firefox. So far I haven't done anything to it other than sign into my Firefox account. Upon trying to reinstall my addons, I got errors like this: "An unexpected error occurred during installation." and "UBlock Origin could not be installed because Firefox cannot modify the needed file." For reference, here's all the addons I had installed before I refreshed: Tranquility Reader, HTTPS Everywhere, Better TTV, Shinigami Eyes, UBlock Origin, Windscribe, Enhancer for Youtube, Dark Reader, and Bitwarden. I tried installing UBlock Origin, Enhancer for Youtube, and Bitwarden, and got the exact same errors every time. I'm really lost on what to do.
