Firefox Support Forum

Firefox runs fine most of the time. If I right-click to download an image, or click a link to download a PDF or other file, or Save HTML, I see the "Save file" dialog, click Save and then Firefox freezes up for a while, maybe a minute or two. Pages won't scroll. I can't switch tabs. I can bring up a different firefox window and it redraws its contents, but I can't scroll or do anything else.

This didn't happen a month ago, then one day after a system upgrade, it happens every time. I'm using FF 123.0.1 on Arch Linux. 64GB RAM, so it's not a memory shortage. I have upgraded one or two times more since the upgrade when this appeared. Chromium is not affected, Thunderbird is fine, and all other software continues to be fine as before, including when saving files. Only FF has this problem.

What is the problem and solution? Are there ways to gather more info to diagnose the problem, if needed?

This is a rebuilt PC after a hard drive died, Windows 10 Pro N version 22H2. and YE

I am trying to access video content on cbc.ca or Amazon.ca and receive an error message that "no compatible source was found for this media" - Amazon or on cbc.ca "Oops...None of the given sources can be played".

Prior to updating Firefox to version 123.0.1, both played video on these sites without an issue.

I have uninstalled and reinstalled FF and the issue persists. I can play the video from these sites with Chrome or Edge without a problem.

I have installed Java and have tried all of the help tips without success:

I have followed and installed recommendations from : https://support.mozilla.org/en-US/kb/fix-video-audio-problems-firefox-windows however the latest Media Feature Pack for windows is from 2019 and is no longer applicable to the 22H2 version. https://www.microsoft.com/en-us/software-download/mediafeaturepack. Windows store does not offer the pack.

The changes suggested by https://support.mozilla.org/en-US/kb/block-autoplay have been applied and no change

I am not running malware bytes or a VPN.

I have cleared my cache, and browsing history, rebooted = no change.

I have no add-ons, extensions or themes installed.

I prefer to use FF, but require that I can view videos from many sites.

I want certain extensions to be able to run in private windows, but not in normal windows. For example, I would browse normally without a VPN extension, and when I open a private window, the VPN extension would be enabled.

on most current macbook, when opening downloaded PDF, it does not open in my selected PDF preference. i have it set for my preferred PDF reader, yet it opens with a completely different one. i have checked all settings i can think of bot on the mac and in firefox, and am flummoxed. all i am finding are windows articles with help, and i checked those too but still nadda. anyone else have any suggestions?

Hi there - Every website seems to come up in English, ie Firefox seems to be translating other languages automatically. (My version is Firefox for Mac 123.01 64-bit.) I am wondering how I can prevent automatic translation of websites. I have had a look in preferences etc, but I do not see anything there to prevent automatic translation. Any help gratefully received! Many thanks :-)

Auto play blocking is no longer working.

media.autoplay.block-event.enabled true media.autoplay.blocking_policy 3 [tried 2] media.autoplay.default 5 [tried values]

Anyone have good values that block auto playing videos?

I'm running Firefox 123.0.1 on Linux Mint 21.2. Something changed after my last update. I visit a number of web sites at which I scroll down a window to a link, click on it to open it, read that link, and then return to the previous page. Examples are news sites like slashdot.org, associated press, or arcamax. Firefox used to return to the place in the original site page where I had clicked on a link. Now, it returns to the top of the original site page, and I have to scroll down again to where I had clicked on a link. I can right click on a link, open a new tab, and then close that tab, but that requires multiple clicks, and I used to just click/click. Is there a way to set up Firefox to go back to the previous behavior? Thanks in advance. ;

The Bookmarks Gadget (under Add Gadgets) appears to have been hijacked. I have dozens of bookmarks and now every single one of them redirects me to https://12jav.net/. I tried clearing all browsing data, logging out/in, and reinstalling the gadget. It seems to have happened after installing the latest version of Firefox, and reverting to an earlier version did not help either. Can you please look into this? Thank you.

Windows Updates (KB5035845) and 10.0.19041.4163

After these latest updates, EVERY, Firefox browser (derivatives included, i.e. LibreWolf, etc...) are opening VERY slowly. Its almost like the browser is freezing while opening for around 10 - 20 sec, then opening. It used to open within a second or two. If I uninstall the updates the problem goes away, BUT, windows re-installs them automatically. After it is up and running its ok. The problem seems to be on startup only.

I can't get Amazon back as a search option Bing is one of the search options selected in search settings, doesn't appear.

If I install an older version will it be ok. Why do they keep installing new updates which cause issues with the one I am using. I installed Opera and will give it a try. Firefox keeps changing things that work.'bold text'

I have been a Firefox user for most of my time on a computer and that's a lot of years. A regular site I visit is Townhall.com. A few months ago I could no longer play videos because the link (video screen) would not appear. The text below where the screen should have been appears. I worked with Townhall on this and we could not solve it. Interesting was that periodically the link would appear but now doesn't appear at all. So I am forced to use MS Edge for Townhall videos.

Then it happened on another site I frequent - RacerX.com. When I try to play a video I get a blank screen with the message: "Unfortunately your Targeted Advertising privacy settings prevent us from showing you this YouTube Video. Please update your consent to see this content." I cannot find anything in settings which should cause this. I changed nothing. Settings are the same as they've been for years. So now for RacerX videos I have to use MS Edge.

I would prefer to continue to use Firefox as my browser but switching back and forth is not productive. As much as I do not want to make MS Edge my default browser it looks like I will have no choice unless you can help me solve this issue.

Above 70-75k characters, text input fields on any site have a ton of input lag -- like, I have to wait 10s after I type a sentence for the sentence to finish slowly updating letter by letter. I've tested across multiple sites, and in Private mode (to confirm it's not caused by extensions, none of which are allowed in Private mode).

I also tried setting `accessibility.force_disabled=1` as suggested here and here, but that didn't help (and yes, I restarted). Disabling hardware acceleration didn't help either.

I'm using the Firefox browser for Android. When I'm on Bluesky with my Android phone and go to create a post, I tap the image to upload an image. I get the post editor box on the top, the keyboard on the bottom. When I tap the image to add a photo, the keyboard disappears leaving only the box to edit the post and it doesn't go on to the next step where I would choose the image I want to upload. I'm using Firefox for Android 124.0 and a Galaxy A53 5G with One UI 6.0. Android version 14. Also, I have it set to use Spanish.

I want to visit a unsecured web site (camping site). I notice these mom and pop websites are unsecured. How do I visit it. I'm a big boy and dint like to be told where i can visit. However, I don't mind a warning.

while reading an MSNBC or Fox News article (for example) from flipboard, suppose there is a video at the top of the article. But I don't want to watch that video... I just want to read the article that appears below it. So I start to scroll down, reading the article, and when the video scrolls off the screen at the top, a picture-in-picture with that video appears at the right side of the article, (sometimes blocking part of the article). If I had wanted to see the video, I would have watched the video! STOP these blasted picture-in-picure pop-ups.

Every time I look for help online, all I see is how to enable/disable the PIP controls, and no help on how to block PIPs themselves.

Sorry for the long post, but I don't know how else to describe the problem succinctly. Jerry (at wit's end)

made this post on reddit too https://www.reddit.com/r/firefox/comments/1bhztyg/non_full_screen_video_player_bug_exclusive_to/ but notice how theres this weird color bar right above the video player, this happens whenever i play anything on hulu.com. any solutions? thanks for any and all responses in advance :)

I don't have the words to describe what's happening here. Please see screenshot. Frequently when using Firefox- since the latest update, it's up-to-date on up-to-date Macbook Sonoma 14.4- this starts happening, when I move around my cursor, the images get all funky, it seems to be pulling in visual information from multiple tabs. Restarting the app clears it out, until the next time it happens. Any thoughts on this?
