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?

YouTube has been so slow in Firefox. It just takes a ton of time for the video to actually play. It's just a spinning circle in a video. I can refresh several times and then it plays. I cleared my cache, history, data...etc everything from Firefox. That seemed to help for a bit. Then it just resulted back to being slow. It's just in Firefox. I played videos in Edge. It was fine. No issues. It's just FireFox. It started most recently too. It wasn't happening a week ago. I even tried going back to an old version of Firefox. Didn't help. Anyone know how to fix? Not using ad blockers either FYI. I just want videos to play normally and fast.

After some time of idle, i.e. leave the computer for some time, say over night. No suspend or hibernate. Back to the computer next morning, unlock. Then Firefox appears frozen/hang, can't switch tab (clicking tab has no response, but not really frozen, sometimes responses after dozens of seconds of lag), page also has no response. Then after around half to 2 minutes, everything back to normal.

During the "hang", CPU load is load, no memory stress (swapping/paging).

Environment:

Firefox 123.0 (64-bit), (actually it bothered me for years)

Linux 6.6.15-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.6.15-2 (2024-02-04) x86_64 GNU/Linux

``` lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux trixie/sid Release: n/a Codename: trixie ``` Not related to particular Linux and/or kernel version.

CPU: Intel or AMD, not related. RAM: 64GB/96GB, free memory more than enough.

I will gather more detailed info later.

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. ;

My Subject pretty well says it. I'm trying to transfer by syncing my desktop Firefox with the Firefox 124 on a newly installed Kubuntu on a new laptop. I have all these functions synced ON. The recent history but not the long-term history, passwords (thank heavens), and all bookmarks got transferred, but not the open tabs/pages. I've done the desktop sync followed by the laptop sync a few times, still without the tabs' transferring. How do i get those transferred?

Over the last week, a little purple icon appears in upper left corner of my firefox browser, it looks like a person viewing a screen. It sits right on top of the red-yellow-green circles that allow me to minimize, enlarge, or close the browser, and renders Firefox unusable. How do I get rid of it?

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.

Please see the attached image.

Firefox believes I have a security key.

What is a security key? Where do I find it? Why does Firefox think I have one?

And why is there no helpful information to explain this confusing UX?

I have been dealing with https://www.mynylottery.org/portal/ for weeks trying to get their software to recognize my location, required to place subscriptions on their site. I have switched off every safety and restriction in settings to open the computer to their search for my location. I finally got them on the phone and they told me that for a reason they don't understand, Firefox is the only browser that is currently giving them problems. It refuses to allow them to pinpoint location of the connecting computer either via wi-fi or ethernet connection. Please provide some guidance and if necessary, contact the NYS lottery to solve the problem.

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?

why can't I use the lingq importer extention? I get a message for all my extentions that says: firefox extension can't read and change data on this site. It's preventing me from using the LingQ importer extention.

To open a link of a website in the background tab is CTRL+click, why is it that to open a bookmark of the bookmark toolbar in the background tab is CTRL+shift+click. It is confusing! A bookmark is a link! For comparison, both of them are CTRL + click in chromium. BTW, there is no explanation in advanced configuration preferences.

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.

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.
