Firefox Support Forum

For the past couple of days when I watch videos on YouTube on my iMac it's VERY slow to start. Sometimes it takes minutes, at which point I have to refresh, and best case it takes about 1 minute to start.

I have cleared the startup cache, cleared cookies and restarted Firefox.

Also, YouTube works normally on both Safari and Chrome.

Not a super 'tech' guy so any basic steps I can take are appreciated.

Thank you!

I'm getting this error when trying to access Instagram posts on here in the past few days:

Something Went Wrong

It opens regularly in every other browser I have.

Hi! I have more than one device for Audio connected to my laptop. Obviously the default device provide by laptop but also I have a Jabra Headset EVOLVE 20 SE MS and Jabra Speaker SPEAK 510 USB/ Bluetooth. Also my webcam Logitech C930e provide a microphone.

When I use Google Meet, in Chrome I can select on Meet Audio Device Select the different microphone or Speakers but in Firefox I can only select the Default System Speaker.

I would like to know how to change between my Audio Devices for the output or can switch between my different speakers.

I've been experiencing a problem in Firefox where, when I scroll, the incoming part of the page momentarily goes blank and then loads to normal. This issue becomes more pronounced on pages with a lot of elements. Also, this issue becomes more vivid in smaller screens compared to larger ones. It feels like the browser is taking time to paint the part of the page.

This issue only occurs in Firefox. I have tried this in Chrome and Safari.

Here's what I have already tried:

• Disabled hardware acceleration and WebGL.
• Disabled smooth scroll and auto-scroll.
• Opened Firefox in safe mode (troubleshoot mode).
• Confirmed that I have no extensions or add-ons installed.
• Reset Firefox.

Despite these attempts, the issue persists. This problem is affecting the usability of the website. How can I resolve this scrolling issue? Any help would be greatly appreciated.

Firefox "Tabs" when operated automatically will not work on links within emails that I trust. When I manually select the link to open within a "Private Tab"(Personal, Banking, Shopping, etc)the link will work, and connect. I have checked the Windows 10(64) Firewall and my VPN, and nothing is set to block Firefox from connecting the auto-opening Tab. What is the trouble?

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."

the size of the offered tabs became too huge in the address bar. Something happened in my browser and it reset all the settings. How can I reduce their size? They take up half of the browser screen

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!

Hi,

am running firefox 127.0.1 on a windows 11 desktop. Numerous sites that use a captcha to login fail. In other words, the captcha never loads and I cannot login to those sites. Such sites include teamfaderpro, Coursera, and bandcamp. All logins fail as the captcha is required to be passed prior to logging in, but the captcha never appears and so when I try to log in, nothing happens and I cannot login.

I have tried the above same sites on the Edge browser and have no such issue, the captcha shows and I can login.

Just FYI, the agent switcher setting change recommended by others previously is not suitable. When I tried that fix I was unable to access a considerable percentage of the internet due to some cloudflare issue, so the agent switcher setting is not an option. So far, I have tried all recommended settings to fix this issue and nothing has worked.

I am surprised no one else is having this issue.

Any help is appreciated, or at least inform google/mozilla about this issue as it has been ongoing (on and off) for me for many months. And yes, this problem is persistent for me at the moment, it remains despite rebooting windows, despite clearing cookies and cache (which I have set to automatically delete when exiting firefox).

I create a account in Jun 23, 2024 but i when i can back in 24 then i see my account is no there means my account was automatically logout when i try to login but i forgot email but i know the pass i have try forget password but it does not solve my problem please solve firefox

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!

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.
