Firefox Community Forum

I would like to be able to download YouTube videos.

Is there a Firefox add-on that will allow me to download YouTube videos onto my MacMini?

I tried Video DownloadHelper and YouTube Video Downloader and didn't see any action.

Do I need to setup settings a certain way to make it work?

What are the steps to make it work?

Thank you for your assistance.

With reference to my question just posted, also now when I click on my Firefox browser, the Yahoo search engine seems to take over and it won't let me come out of it. Mark

When i log into Instagram, Gmail, or Facebook i get a message that says "this browser no longer supported. Update to newer version" i am running 132.0.2. i have been using Firefox since version 0.7 and still prefer FF to all other browsers.

Got a number of devices with Firefox installed, all of them Firefox Sync'ed. Most of them on rapid release version cycle and a couple of them on ESR.

When https://support.mozilla.org/en-US/kb/website-translation it provided a clean way to browse entire pages automatically translated. Problem is that the translate option is not there.

I'm at work right now on ESR 115.15.0 / Windows 10 64-bit and no translate icon appears on the address bar when checking German or French or Japanese sites (for example). Comparing my own browser settings to another, non-ESR FF it seems that on ESR something is missing. There is only a reference "Firefox Translations" and a "Exceptions" button to it. Check the attached image.

Can't tell if this is a bug or a feature (ie ESR lacks Firefox translate).

Netflix says I need the the latest version of firefox. At the top of the screen it says "Firefox is installing components needed to play the audio or video on this page. Please try again later"

As far as I can tell nothing is installing and I need to actually do something to resolve this issue. Unfortunately I don't know what. Please help me resolve this issue.

I have had a series fo problems over the last 2 months. All different, but on closer inspection, all connected to recaptcha and login security.

I have not been able to log into my wordpress admin website for 2 months. It just hangs with"Verifying you are not a robot". I can login using Chrome.

Now I have just taken out insurance for my car and have set up a login for my insurance portal - and can't login because "Recaptcha cannot determine that you are a human".

I have searched and found that there was a bug with recaptcha and firefox, but that this was fixed. In any case, this fix did not work for me.

Can anyone please tell me what I should do so that I can login to recaptcha sites?

I got a new PC and tried to import my Firefox bookmarks. But on the right side menu when you click bookmarks, it only show recent ones which actually aren't recent at all. How do you get that selection to show all of the bookmarks instead of recent?

Also I'm still getting a prompt underneath the address box to manage bookmarks and I can't get rid of it. How do I clear that out?

I am starting to use the new utility which allows me to group tabs. But I would like to see only the name of the group and not the whole list. How can I collapse the list of tabs which belong to a group leaving only the group name shown. Then with a click I should be able to see the corresponding list of tabs if I need it. Saving and closing a group is not a solution, as the group disappears from the Sidebar. Thank you for your help. Best regards Ray Ballisti [edited] @bluewin.ch Switzerland

There a way to cast videos from my firefox desktop version to my chromecast?

I need to use another browsers (chrome, chromium, edge) all theses works well.

Any solution?

I just got a new laptop and have set Firefox as the default browser. Duckduckgo is my search engine which I could use on the Firefox home page with my old machine. I do not want to search with Google. I see no way to eliminate Google as the default search engine. How can I change this?

Thank you

I've found a solution to the blurriness of the emojis, I've put it in the end of this post, in bold ⤵⤵⤵

My problem is that emojis look bad on Firefox compared to Edge_128.0.2739.79. Two screenshots are attached of bing.com & a Google Doc (left half of both pictures is Edge, other half Firefox). The problem persists on all the sites to a varying degree.

Steps to replicate: A] Open 2 sites in latest Edge & Firefox on Windows 11 (the examples that I've used in the screenshots): https://www.bing.com/ and an Empty Google Doc. B] In the search field of bing and in a new line in an empty Google Doc, copy the following example emojis (That were inserted using the 'Windows_Key+V' which summons the emoji Keyboard of Windows): 🏀🚕 C] Compare the quality of the emojis rendering between the browsers when unzoomed and when zooming.

I've tried in FF (to no avail): A] Disable hardware acceleration in settings (w/ FF restart). B] Setting "gfx.font_rendering.cleartype_params.rendering_mode" from -5 to 5 (w/ 10+ FF restarts). C] Setting "gfx.webrender.quality.force-subpixel-aa-where-possible" to true (w/ FF restart). D] Using both emoji sets in the "Segoe UI Emoji" & "Twemoji Mozilla" fonts in the "font.name-list.emoji" setting, both sets gave me blurry results (w/ FF restarts). D] Disabling all add-ons (w/ FF restart). E] Setting new Firefox separate clean install. F*] In Windows setting the scaling factor to 100% in Windows->System->Display->Scaling_Factor (w/ FF & Windows restart).

How can the blurriness of the emojis be fixed so to make them crystal sharp like in Edge?

Solution: A} Download Noto-Color-Emoji font from https://fonts.google.com/noto/specimen/Noto+Color+Emoji Ensure that your are getting the full resolution font (which came at ~23MB as of 2024.09.23) B} Unpack the font and install according to the on screen instructions. C} In FF in "about:config" find the "font.name-list.emoji" setting and rewrite its value field to "Noto Color Emoji, Segoe UI Emoji, Twemoji Mozilla" (w/o the quotations marks). D} I've attached a screenshot w/ the result, It is marked w/ the red writing of font.name-list.emoji on it.

For the love of God. Effective yesterday, why can I no longer open a new tab in Firefox browser on a Windows laptop? Is this a bug or was it an intentional update to delete the visible 'open a new browser' plus (+) icon, and make it elusive, frustrating, and impossible to open a new tab? I found a workaround (right click and select the new "New Tab to Right" option from the list of drop down options), but this circumvention is mindboggling and inefficient at best. Please help. One of the things I have loved about the Mozilla organization for the last nearly 20 years of using Firefox has been the organization's dedication to make internet browsing simple and safe for users. Replacing the 1 step 'open a new browser' plus (+) icon with a 3 step right click move is the opposite of simple. Please troubleshoot.

Ok so I usually choose these option to remember history and from time to time delete Browsing & download history and Temporary cached files and pages.

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-28-08-45-55-a5277f.png

Note: I have "Open previous window and tabs" ticked in general settings which also has a restore previous session option in the history menu. This brings back previous session with tabs etc as is when I close FF. https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-28-08-45-51-cf2daf.png

I thought I could automate this on exit but don't think its working right. So I change the option to "use custom settings for history" and tick all three options:

Remember browsing and download history Remember search and form history Clear history when Firefox closes For "Clear history when Firefox closes" I ticked Browsing & download history and Temporary cached files and pages. https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-28-08-45-43-b10213.png

The issue is the restore session option is missing and FF opens with all previous tabs gone. I am frankly not even sure what else is missing such as cookies, site data etc. Is this meant to work like so?

This topic appears to show up a few times, but none of the solutions work for me (e.g. they were using A/V or "it just worked"). The error I get is also different.

This a pretty fresh install (migrating from Chrome so I'm currently re-logging into all my sites to ensure I can access everything I need.. and going through MFA hell heheheheh).

Everything is mostly fine, except for Synchrony Bank.

I go to login at https://auth.synchronybank.com/account/login, enter _any_ username or password (doesn't matter if I enter the right details or the wrong ones), and as soon as I click "sign in" I get an error page

Looking in developer console, the error reason given is NS_ERROR_NET_INTERRUPT while trying to POST to auth.synchronybank.com. Every so often I get PR_IO_TIMEOUT_ERROR but over 90% of the time it's NET_INTERRUPT.

This occurs also in private browsing and also in safe mode. I even created a new profile and tested it from there; same issue.

I've tried lots of things related to this (e.g. setting network.http.http3.enable to false), added the domain to the advanced tracking exception list, and I'm running out of ideas.

I can see traffic flowing to akamai but (it being https) I can't see what's inside the traffic. Could akamai be objecting to something in the content?

FWIW, I can login with Chrome on the same machine.

I took a look today and I had 237 MB in cookies! This was after clearing the cache of all files. I've only had this (new) machine a couple months.

Short version: Sites have "cookies" from 200kb to as much as 34MB! For many of the sites over 3MB I have no account and have visited them only briefly.

To be clear, I don't care about the space being used. It's trivial. But what the heck is FFox storing and calling it "cookies"? Last I checked, a site was still limited to 4K size cookies and perhaps 50 per domain. So how are we getting to MB+ sized "cookies" per site? Again, the cache was cleared, so what's left aside from trivial cookie files of <4KB?

I just noticed that when I start writing in the Firefox URL bar there is a blinking straight bar that remains at the start. And if I click of somewhere else and then start writing again, the bar remains blinking at the start of the new text. I also don't have the straight line you get when moving left or right in the text using the arrow keys.

I couldn't capture the bar with a screen shot so I have edited the images to where the bar is when beginning typing, and then after I have clicked of the text bar and then entered it again and typed some more.

Thanks for any help I can get.

On certain websites, I see that the background color of the new tab page replaces the default background color making the content unreadable, example:

If I browser this website: https://typespec.io/docs

Here's what I see (see the firsrt attached screenshot). Now, if I open the same URL in Private browsing, the background color changes too (see the second screeenshot). In the 3rd screenshot I'm adding the reference rendering, that's how I expect this website to render (Edge).

In the screenshot 1 and 2, the background color is exactly the same as the one used by the new tab page when I open a new tab.

Questions: 1) Why is that? 2) Can I change that?

Context: I'm trying to switch to Firefox (from Edge)

I run the latest version of Firefox.

Lately it refuses to open on first attempt - be it from a start menu link or double-clicking the shortcut on my desktop or trying to open a html file directly.

It's annoying and i'd like to fix it.

I've done all the usual stuff like clearing the cache.

tia.
