Firefox Support Forum

I've been unable to complete the installation of the latest version of the Firefox browser for Windows 10 for several weeks because my Bitdefender online protection repeatedly blocks the connection to incoming.telemetry.mozilla.org saying: "firefox.exe attempted to establish a connection relying on an unmatching security certificate to incoming.telemetry.mozilla.org. We blocked the connection to keep your data safe since the used certificate was issued for a different web address than the targeted one."

So, this is going to be an incredibly weird question, but is anyone else having this issue? As of about two days ago, any time I try and load a video on youtube it will refuse to load for upwards of 30 seconds, however if I toggle the new stable volume option off/on it instantly loads. It will then play for about 2-3 minutes or more depending on video length (sometimes way more) before the buffer bar will stop entirely, take over two minutes to load the video again, then keep playing. More often than not doing this multiple times per singular video. Often times it won't even load anymore at all and I am forced to refresh the page and toggle the stable volume once again.

I've tried disabling every single extension I have, including ad blockers, restarting the entire browser, and using a different account, and it still happens no matter what. However it is not an issue that occurs on chrome or edge, so I'm at a complete loss of what is causing this. Looking up this issue comes up with next to no results, so is it possible this is a youtube issue or is something seriously wrong with my browser and I need to re-install it?

when my operating system is in dark mode, and i browse a website that supports darkmode. the dark mode setting is not changed in containing iframes.

so the following javascript does return different results: window.matchMedia('(prefers-color-scheme: dark)').matches false top.window.matchMedia('(prefers-color-scheme: dark)').matches true

Hi,

I'm switching from Edge and have a frustrating issue.

In Edge I am very used to having separate behaviour for links with left and middle click.

i.e. from Gmail, if I left click a link it opens in a new tab and switches to the tab, if I middle click a link it opens in a new tab but stays on the current tab

In Firefox both seem to be controlled by the single setting.

I have looked in about:config and tried changing a few flags but cannot seem to find a combination that works how I want it.

Can anyone help?

This is a real dealbreaker for me and I will switch back if there's no solution :(

TIA

Hello, I have a problem with the languages/dictionaries in Firefox (Linux) and would appreciate some help.

Currently the German language is not recognized in the spell checker or is apparently not available.

When I click on the context menu in a language field (right mouse button), only "Englisch (Vereinigte...." is displayed under "Sprachen" (which is "Languages" in the english menu).

However, the German language pack is apparently installed, because when I click on the link to add it in the context menu, the language extension for German already says "remove".

I would also be happy to provide pictures.

Incidentally, the interface in Firefox is already correctly in German.

Deleting cookies, restarting Firefox and restarting the system have unfortunately not helped.

Can anyone help me, I'm getting desperate?

Thank you very much!

I have several g-mail accounts that I used to open on Firefox - until yesterday. Now I'm getting a silly message below:

I'm working on ASUS, on Windows 86bit. If I reboot my PC g-mail works again for a couple of hours. I have no problem accessing my g-mail accounts from Chrome.

Any help? Thank you all Marina

I am trying to get rid of the fullscreen animation i have tried changing full-screen-api.transition-duration.enter and full-screen-api.transition-duration.leave to 0 0 but the animation still plays

I can no longer use my camera on firefox, firefox displayed some message about camera when we were trying to chat, but I missed it, I have granted relevant permissions on the site, that we use reularly. The camera icon on the address bar appears red, and I noticed that in Windows security, it lists firefox access requests, but shows no way to grant these requests.

I am not tech minded so please if anyone could keep it simple, I would appreciate it.

I am using Firefox 127 on Ubuntu.

When I press the Control key, I often lose focus in the window I am currently viewing. This is annoying as it prevents me from copy-pasting for example.

Sometimes the focus is back when I release Control, sometimes it is lost and I have to click again on the text field. It does not happen on all websites, for example support.mozilla.org works well, but it happens on duckduckgo or overleaf.

It does not seem to be the same as existing issues such as [the "show mouse when press Ctrl" of Ubuntu] (it is disabled) or an addon (the problem still happens in safe mode).

In case it is useful, when I press Control the tab bar background goes slightly darker, see attached images.

Thanks for your help :) Nicolas

Hi, Like many other people I have Firefox setup just the way I like it - a few windows open, some windows with 10 tabs open, my most common pages open as pinned tabs, other windows with stuff I want to remain at the front of memory at least temporarily. The last 3 times I have updated Firefox, it opens without restoring my pages. I look in the History menu and both the 'recently closed windows' and 'recently closed tabs' items are greyed out. I really, really don't want to move away from FF, but this behavior is beyond frustrating. I've already checked I have 2 profiles: default and default-release (default). I tried 'Launch profile in new browser' for the other profile but it's empty. Any ideas how to figure out what the problem is? I'm on Windows 11. Thanks!

In Firefox, after a reboot, how can I re-open my previous sessions?

Originally I had quite a lot of open browsers & tabs. Then I needed to do a reboot, and now I've lost those previous sessions.

Usually I just open Firefox, and this opens one browser, and then all of my previous browser, and tabs reopen, but this time Firefox crashed, and its popup said it needed to restart, but it would re-open my previous browser and tabs, but it didn't.

After following the usual Firefox help guides, it still wouldn't re-open my previous sessions. Now if I ask it to open my previous sessions, it just opens the recent help guides, and not anything before the crash.

So is there a backup file of my missing sessions that I can roll back to?

Dear Sir,Mrs,

I have a problem with the import of my backup in FireFox. I made an backup with MozBackup (.pcv) with my old Computer, Now with the new one and new FireFox program I can't import it, as the import will not recognive the used format.

I have tried to solve it to convert it to .zip but then the import won't run, or quit's after about 25 to 30% import.

How can I resolve this problem, which also count's for the new Thunderbird. As I am now missing all the maps at both programs.

Best regards, Martin van Steenes

Firefox, like most browsers, is full of jargon and terms which are never defined. So, for a new user, what should be simple become complicated. Developers obviously thought that everybody understands, but it is not true. It would be helpful if there was a term definition for each term and symbol used. I find my self in a kind of rabbit hole when trying to do things, and even when I ask for help, there is no term definition help.

I really appreciate everything you do, but I am a boomer (Loud and Proud), I did not get born with a device attached to my hand, I am a digital imbecile.

With all that in mind, it has become too difficult to keep up with the digitalisation, at least in my case. So when you send me suggestions and update procedures I end up just closing everything, too much to read, too stressing, but the suggestions keep coming every time I open the firefox browser. Can I not just keep the version I have and decline any new versions.

I also have a problem in regard to language, it is set to English, but I do not care for US English, I would like to have GB English, but somehow it won't accept that.

What can I do?

Kind regards,

Xamama

I enter my username & password and nothing happens. This occurs when I use Dashlane AND also if I enter username & password manually.

I can access my account successfully using Edge.

For the last few days Firefox keeps dropping off as the default browser and seems to be defaulting to the Avast Secure Browser thats installed instead.

I keep changing it back via both Firefoxs settings and via Windows default settings but within 10 minutes it falls off again.

How can I make sure Firefox stays as my default browser?

Picture in Picture is an awesome feature and i love that Firefox comes with it by default.

However I do wish for one thing. So we can lock and "click through" the picture in picture, instead of our mice being able to click it by mistake when doing other things (such as grinding on an MMO or something.)

Is there any way to get these options in the near future? It'd be great to play some games when watching a video during slow times! Thank you!

I would like to create bookmark folders WITHIN a bookmark folder. Example: I search the American South, so I have a SOUTH bookmark. But within that bookmark, I would like to have a subfolder for each state. Please help!
