Hello, I have a problem, where many bookmarks from my old device are synchronized to my current Firefox browsers (on PCs) even when old device is removed months ago. What worse, when sync is performed, it duplicates tabs, now in "Bookmarks menu" I have albost 2000 bookmarks what are duplicates od ~20/30 ofer month. If Firefox do sync now on 2nd PC, I will get again 2000 and plus something bookmarks. Deleting it gives nothing. It comes back again and again. Normal Bookmarks tabalso gets old tabs and duplicates.

So I wanted to read PDFs trough firefox with a dark theme, looked up how to do so online, and people say to change the "about:config" option "pdfjs.viewerCssTheme" to "2" instead of "0", I did that, tried opening a PDF, nothing happend, it was still black text on white backgrounds. Tried closing firefox, reopened the pdf, nothing happened, still white backgrounds. Tried to check if it might have to do with that specific pdf file's config, created my own PDF file from a word document, tried to open it, still white backgrounds. Tried disabling extensions, (which I use four of, UBlock Origin, SponsporBlock, Return Youtube Dislike and Translate this page), didn't work. Tried enabling the option on my laptop, didn't work. Tried a bunch of other stuff and it still won't work. My Firefox version is 109 and I'm using Windows 10 I also don't want to use the console/file edit thing with grayscale(1) invertcolor(1) or whatever it was since it also reverses the colors of images instead of just the backgrounda nd text color.

Does anyone know how to configure Firefox to stop the annoying google log-in pop-up? I've seen others ask the same question, but I have not seen any functional answers. I've never had a google account, for anything. I don't get the pop-up with other browsers, like Falcon or Brave. It's just a problem on Firefox. I appreciate you help!

I've the same problem as https://support.mozilla.org/questions/1317794#question-reply but after following the steps for the solution, it doesn't work for me. Does it have to do with all updates since this question was answered? I've created the chrome folder. I've created userChrome.css file and added the following without "`" marks in it and saved it and restarted firefox after changing the toolkit.legacyUserProfileCustomizations.stylesheets = true . ```

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */

#appMenu-fxa-label > .toolbarbutton-text { visibility:hidden !important; }

```

It doesn't work for me. Please have a look.

bold textAfter downloading latest version of Firefox, lost all bookmarks. Followed instructions on restoring, window showed all restored, but all are still missing.

Bonjour, Depuis une semaine, j'ai ce message à l'ouverture de ma page d'accueil Orange, avec Firefox !! PR_END_OF_FILE_ERROR il n'y a qu'avec mon navigateur et pas sur Chrome ni Edge. Avant, j'étais le seul impacté par ce problème et maintenant les trois P.C de la maison le sont. Deux W11 et un W10. En déconnectant le VPN le souci n'existe plus. Merci d'avance pour votre aide.

on other browsers I was able to go to history and see at what time of day I viewed a certain web site. Is that function on Firefox? This came in very handy so Please add this function! Thanks!

When changing the primary password I would expect the logins.json file being rewritten with new pairs of encryptedUsername and encryptedPassword (now encrypted based on a new primary password). But this is obviously not the case. But maybe I just didn't understand the way this works?

so, my computer is getting old, and because of that, it's slowing then. Firefox isn't helping much because it uses too many processes and memory. i tried deleting some extensions, I tried using task manager to close separate processes but i always end closing the wrong one and closing firefox completely i tried going to dom.ipc.processCount and change the count to 1. I'm so confused, it's slowing down my games i play.

Ever since Firefox updated today I've been unable to use the browser. It takes at least 5 minutes or more minutes to load, I can't manually log into any websites until the speeddial finally loads, and the speeddial addon refuses to come up for at least 5 minutes, I can't log into Dropbox even with the speeddial up and running because the capcha won't popup...and on and on.

What in the world has been done to it? I'm using another browser just to contact support.

The free version allows for 5 masks. Is that 5 lifetime masks or 5 active masks? Example: If I set up 2 masks I have 3 remaining. If I delete one of the set up masks do I now have 4 remaining or have I still used up a mask even though it was deleted giving me 3 remaining? Thanks

Nice to meet you all. I have poor English skills, so I use a translator to post. Thank you for your understanding.

I would like to report on a problem I found today.

First of all, the symptom is "Unable to log in at Evernote.com".

To be precise, if you try to log in using a normal ID/PW on Evernote.com, it will respond as if the PW is incorrect.

However, since I checked the ID/PW several times, I determined that there was no problem, and as a result of trying the following combinations, I determined that it was a problem with Firefox for Desktop.

(1) Desktop , Using Firefox -> Can't Login. (2) Desktop , Using Microsoft Edge -> OK (3) Desktop , Using Google Chrome -> OK (4) Android , Using Firefox for Mobile -> OK (4-1) Android , Using Firefox For Mobile (Desktop Mode) -> OK (5) Android , Using Google Chrome -> OK

In the same experiment as above, each version is as follows.

Desktop Firefox: 109.0.1 Mobile Firefox: 109.1.1

My guess is that Firefox's anti-tracking privacy part has a problem with the evernote.com site at some point.

Turning off Privacy Tracking Prevention does not solve the problem. If there are other users reading this article and have an Evernote.com account, please try logging in.

For now, I'm using a different browser, but I hope it works out normally.

Have a nice day everyone.

I have tried watching videos through chrome and other browsers by searching something via duck duck go and watching that video on duck duck go, and it works on other browser so it must be specific to firefox.

Whenever I try to watch a video, in the drop down bar firefox select to mute audio for some reason. I then select 'allow audio and video' and refresh the page but the video is still muted for some reason. This also happens when I try to use other video sites. This has only started to happen recently in the past two days (and yes I am updated to the latest version of firefox).

When using "send tab to device", the submenu previously showed all synced devices, in my case, more than 10 devices. Recently it only shows 4 devices and there is no way to access the other ones. Is this broken or is it a recent change? If so, can I revert the behavior with a preference?

Under "manage devices", I still see all of my synced devices, they just don't show up in the "send to device" submenu.

I'm trying to get rid of these blue selector things. Apologies that I don't know what they're called. They appear at random times and I cannot force them to appear. Just happens randomly it seems when some text is selected.

Can something in the about:config be toggled to disable this?

Thanks.

Hi, I create an account to sync Bookmarks, Passwords, Add-ons, History etc from one computer to an other. I successfully created the account, verify mails, checkbox all features to sync in settings, and click on "sync' multiple times. But nothing is synced on my new computer. On the log I saw (about:sync-log):ab

Can you help me please ? Mrs RICHTER

I've started getting this error message on certain websites (always the same ones):

The page isn’t redirecting properly

An error occurred during a connection to www.manek.org.uk.

   This problem can sometimes be caused by disabling or refusing to accept cookies.

The same websites still work fine on Firefox mobile, so it's nothing inherent in the sites themselves.

I have only noticed this in the last few days. I had just updated Firefox to version 109 – but it's not specific to one version of Firefox either, as I tried on one of my Macs which hadn't updated yet and is still on version 107, and the issue was replicated exactly the same.

I have tried clearing the cache, restarting Firefox, etc.

Can anyone help me resolve this? Some of these are websites I use quite a lot for my work, and it's frustrating to have to do anything just on my phone.

The latest Firefox update appears to break video playback on Linux. I am having issues playing video on Twitter, Facebook, and Locals. YouTube video still plays. I have not enabled any new ad blocking and have also not changed any settings. Looking at the Troubleshooting Information in Firefox reveals nothing that is suspect.

I installed TotalAV webshield & now firefox won't open full screen. I disable webshield, Firefox opens full screen. BUT I use webshield on chrome with NO ISSUES. I contacted TotalAV, and they said the issue is with Firefox. So...why is Firefox having an issue opening fullscreen when I enable webshield?

I am trying to put a shortcut to a web site on the Desktop. Using the the padlock on Firefox 109.0(64 bit) puts it in a sticky note on Desktop instead of a shortcut on the Desktop.

I am running running on Fedora 37 KDE where this does not work.

Using Fedora 37 Workstation (GNOME), the shortcut is created and works.

How do I get the shortcut to work on Fedora 37 KDE?
