unable to see cast option on few websites like most websites. I tried to install the fx_cast option where I can see the cast icon now, but when I play youtube videos and click on cast button (fx_cast), its not detecting my google chromecast. Google chromecast is detected in edge and chrome browsers, but why is my TV not detected in firefox. Like I cannot see the cast icon on many websites where I see the cast icon on edge and chrome browsers, the icon itself is missing in many websites. Please make sure the wireless TV is atleast detected in firefox browser. I have tried so many changes and it does not detect my wireless tv or does not show my chromecast tv signal. Something is wrong with your browser, its not working fine. I have enabled the flag casting in the browser about:config as well. Appreciate it if you can please fix it asap as the streaming is abs fine in firefox browser and the same website runs slow in chrome and edge, which is why I need to use firefox to cast to my tv. Appreciate your help in this regards.

Thanks Manu

Recently I was having trouble using Firefox with my web based Outlook email and asked Microsoft for support. In their reply they recommended that I reset Firefox.

I am reluctant to do so as I don't want to lose all my add ons which have accumulated over time as I am not sure about how to get them back if I lose them with a reset.

Is there a way to reset Firefox but keep my add ons etc?

I would appreciate your advice and thank you in anticipation.

Hi! There are multiple recent threads on this issue, and not one of them has a solution, so I'm asking again. I want to increase the font size of the top header text, specifically the bookmarks toolbar, search bar, and tab titles. The text is too small for me to read. It would also be useful if I could increase the font size for the applications menu (the hamburger drop down menu in the far right of the header).

I do not want to increase the size of anything else, so changing layout.css.devPixelsPerPx is not the solution. I have changed my global zoom settings, and set them specifically to "Zoom text only", but this setting does not effect the bookmarks toolbar or the search bar. Changing the default font size also does not increase the size of this text.

Just to clarify again, these threads are not solutions to my question: https://support.mozilla.org/en-US/questions/1214027 https://support.mozilla.org/en-US/questions/1293358

Recently, I've been unable to view paid for video, for example on Netflix. I get the following error message:

The WidevineCdm Plugin has crashed. FATAL Clpp-Error [Category 6 - Code 6002]: {"browserError":""}

I'm using a macOS 10.95 and, says Firefox,:

"Note: The current version of Google Widevine is no longer compatible with older macOS versions such as OS X 10.9 and 10.10. Only macOS versions 10.11 and above are supported."

So my question, since it seems my mac is no longer compatible with Widevine, is whether there a way for me to watch video on Firefox? Perhaps with another plugin? Or no plugin? Perhaps this is an issue to take up with Widevine?

Thanks in advance.

is there a text-to-speech feature baked in Firefox. if not so could you recommend me extensions like speechify in chrome which sounds natural and have many features.

I live with Firefix always in full screen. I Don't like seeing any bars or buttons of any kind.

Befor the latest update, when I moved my mouse to the top of the screen my tabs popped down and in the top right corner was the standard icons for "minimize" "maximize" and "exit".

With the latest update the tabs are there but the 3 buttons have gone.

If I exit full screen (F11) then they are there again, but I dont want to have to exit full screen every time I change between programes which I do every few mins. I'd be popping pages in and out of full screen every few mins!

How do I get the buttons back all the time?

Before the new update whenever I downloaded a file it would ask where to save the file to every time, now it just asks once then automatically saves any new files I download to the same folder as the previous ones, forcing me to then go to that folder and manually move it to the correct folders. Is there any way to change it back to the right way it was done before they decided to remove our choice? My setting is set to "Always ask you where to save files", with the emphasis on "Always".

Dark Mode used to work beautifully in Firefox. Today it stopped working. I can choose Dark Mode in the settings page, and the settings page itself then uses Dark Mode. But Dark Mode does not work in any of the other pages, only the settings page. I think it must be a flaw in an update that was installed automatically today. (September 7, 2021)

Is there a way to uninstall this update and go back to the previous version. Dark Mode used to work beautifully and Firefox was my favorite browser. Can someone help? Thanks.

I am using firefox just for a few days, then when I go in to my Add-ons setings, it said All add-ons have been disabled by safe mode. So what is safe mode how can I turn it off!?

I downloaded Firefox 52 ESP to try and enable the java plugin. I had Java installed beforehand. However, even on this version, when I go to Options -> Extensions & Themes -> Plugins. I wanted to know if there is any way to actually install the Java Plugin, and if not, what version of Firefox would allow for that. Thanks.

Hi, I'm using the latest firefox version 89.0.2. There's a large tab bar at the top. I never use tabs. Safari doesn't show the tab bar unless multiple tabs are being used. This leaves more space to show webpages. I'd like to hide the tab bar permanently or when only one page/tab is used. I guess that means the red, yellow and green mac circles in the upper left would have to be moved to the lower bar, by shifting the back and forward arrows slightly to the right, as is done on Safari.

I looked online for suggestions. chrome.css files were mentioned. But they didn't explain what those were or how to create/access them. So the guidance was not helpful to those who didn't understand those files, like me.

Can you please let me know how to hide the tab bar?

Based on all the comments I saw on threads, it seems many others think the tab bar wastes space. It would be great if Firefox preferences provided an easy option for hiding the tab bar.

Thanks, Frank

Hello, my old NAS on my intranet (not visible from outside) supports only TLS 1.0. How can I enable TLS on Firefox on a single IP and on a permanent base ? For obvious reasons I don't want to enable it in general..

Firefox starts blocking uBlock Origin and other ad-blocking add-ons in China on addons.mozilla.org ?

Recently [1], some users reported that uBlock Origin [2], AdGuard AdBlocker [3], AdBlock For Firefox [4], and AdNauseam [5] were restricted from being accessed by users in mainland China.

When users in mainland China try to access the above ad-filtering add-ons on addons.mozilla.org, the website returns 451 Unavailable For Legal Reasons instead of the normal 200 OK response, and the body of the page states "This page is not available in your region".

The facts can be validated by reproducing the test results below.

By the way, this has nothing to do with China's "great firewall". This action of blocking was performed by Firefox in China. Firefox in China has a long history of arbitrarily blocking websites even for non-political or legal reasons and was found guilty by the Court in China back in 2018 for several such cases.

Sources and evidences: [1] According to Blocky's test logs, restricted access initially began no earlier than March 8, 2022 and no later than March 19, 2022. Users report: https://bgme.me/@bgme/107986773834355287

Testing results (by blocky.greatfire.org) Before: https://blocky.greatfire.org/api/url_test_result/18800410?format=ooni After: https://blocky.greatfire.org/api/url_test_result/18861443?format=ooni

The same testing results can be reproduced by testing the below URLs from a China mainland IP address or blocky.greatfire.org which uses multiple China mainland IP addresses in different cities.
