Since about one year I am unable to use Japanese input only in Firefox. When I try to switch with fcitx and control+space, nothing happens. However, fcitx-mocz works everywhere else on my computer (i.e. terminal, thunderbird, other browsers, etc.). Furthermore, I uninstalled fcitx and everything associated with it and reinstalled it according to this thread: https://support.mozilla.org/en-US/questions/1367181 (just with mocz for Japanese). This also didn't change anything. Any help is appreciated! My system: Operating System: Linux Mint 20.3 Kernel: Linux 5.15.0-91-generic Architecture: x86-64 fcitx version: 4.2.9.7 Mozilla Firefox 121.0

Hello there. I'm used to pressing Super(Win key) + Grave(`) to type "`" because the Grave key itself is a global shortcut for opening the terminal window. It works as expected in the other applications, but not in Firefox input fields. If the site is capturing the key presses, it will handle the super + key as usual. For example, GitHub will surround the selected word with ` symbols on grave key press. This problem is not limited to super + grave, but any other letter. For example, Super + q is expected to produce the letter "q", but in Firefox it produces nothing.

I'm trying to identify why the Super + key behavior in Firefox is different from other systems and if I should open a bug or not. Maybe this is the same bug as https://bugzilla.mozilla.org/show_bug.cgi?id=1626609. Thunderbird has the same problem.

Firefox: 123.0.1

Hi,

This is for https://outlook.live.com where I cannot access my full list of folders. I am using Firefox on Linux (in Fedora 34) and my scrolling feature hasn't been working for a few days now. When I search for an email in one of the inaccessible folders, the folder does appear.

As an idea... I added https://outlook.live.com to the pop-up exemptions, no luck.

Any suggestions on how to fix this?

Many thanks!

Hello everyone. Well, I've been using Firefox for a few months, maybe a semester now, I don't remember. But the point is that since yesterday I have been facing a serious problem of not being able to download any type of file (MP4, PDF, .JSON, ISO, etc.). I've already used the troubleshooting mode and I've also restarted my laptop, but it didn't help. I've also gone to the advanced settings (see 'about:config > browser.download') and reset/deleted the data for each command but the problem still persists.

What happens is the following: I click to download the file in question, however, nothing happens other than the page loading that commonly occurs when downloading something. Still, the file does not appear in the downloads tab and there is not even the option to choose where to save the file (e.g. Downloads folder, Documents folder). The download simply appears to have failed.

Exactly, it 'appears', because today I discovered that all my downloads were being directed without my permission/action to the 'downloads' folder (And that's not where I want them to go). The problem would be smaller if only this happened, as I would then just get the files downloaded there and then change to the desired folder, thus trying to move forward despite the problem. But the downloaded files themselves are not operational, they have the icon when a file is still downloading, in addition to not having a name, everything being just a cluster of codes.

In the end, there are files, large and small, that have no use and that I don't even have control over where to direct them. Which is still a huge problem because I still technically can't download anything from the browser. Please, I really need your help on how to resolve this problem.

Note: Also, when I close and open the browser, the first download I try appears in the downloads tab, but it fails instantly and cannot be resumed, making it an eternal failure.

Hello, this is a problem I've been dealing with for nearly 2 months now. Currently using Linux Mint Cinnamon

The browser won't connect to any websites or even try to load them, anytime I search for something it immediately goes to the error page. I've been struggling with internet on my PC for months and all was fixed when I hooked up ethernet, except for Firefox.

I've gone into about:config countless times. I've restarted it twice, I've tried installing the flatpak version and it's exactly the same result. I've deleted it and reinstalled, nothing. I've unchecked everything I've changed in about:config, once again nothing.

I can't update it as for some reason it says it's disabled by system administrator, which I don't remember enabling. I checked the firewall and it's perfectly fine. No infections were found when I scanned as well.

It's starting to become frustrating and I can't even do anything on my PC because it's acting up. Any and all help is more than appreciated and welcome. Thank you.

I've looked for solutions, some had weird MTU settings, some needed to enable hardware acceleration in Chrome, but haven't found a solution that works. Created a new profile to try that out, but still no dice.

I can do a test recording in Google Meet, which displays my video just fine, but when playing back, it's just a black screen, and that is also what happens if I share my screen. Participants get a lot of black.

I've been using Firefox with Google meet for many years, and never had this problem before. I did report the issue in Meet, but it's not likely to attract much attention from Google.

Suggestions much appreciated.

Hello Is it possible to get Firefox to clear cookies at the close of Firefox but still keep forum login details and not delete forum login data. Help appreciated Thanks

Hi I have been using firefox on linux for a while without updating it. We are artsellers and I used to be able to log in and out of an artplatform without any problems. It's now been a few weeks since logging out is not possible any more on this platform which means that I am constantly logged in which I really do not want. The menu does not work anymore on this side whereas it works with other browers. I already contacted the platform. They cannot do anything about it themselves and asked me to contact your team. Please help. Thank you Best regards from Germany C. Marsac

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. ;

cannot download firefox browser because I have an expired chrome browser that I'm supposed to delete first -

However - have tried a dozen or so ways to do just that - or so it appears and still cannot download the

firefox browser and after much frustrated key pounding find evidence chrome is not really deleted - help losing

my mind - I'm 77 years old and not computer literate but not senile either - i hope

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.

Hello, Firefox keeps crashing every 1 or 2 minutes. thats a new Endeavouros installation and firefox was pre-installed. system is fully updated.

would you please assist troubleshooting the issue

The integrated webcam (IMC Networks Integrated Camera, according to lsusb) on my linux laptop does not work in firefox (v124). It works in desktop apps (eg webcamoid), and chromium. I've checked the permissions (about:preferences#privacy), and that is not the problem. about:support does not list the device in the input at all. I've tried using LD_PRELOAD=/usr/lib64/libv4l/libv4l1compat.so, but that has not helped. Does anyone have any suggestions?

I want extensions to have white/black-lists, so they're only allowed or blocked on certain pages e.g facebook container ruins instagram experience... and I can't block it on *instagram.com* Such feature would significantly enhance UX on firefox

Thanks, Rob.

I'm trying to create a Drag & Drop file feature in my web page following this doc https://developer.mozilla.org/en-US/docs/Web/API/HTML_Drag_and_Drop_API/File_drag_and_drop

The dropHandler function works as expected the first time I tried to drop a file into a "drop area" div, but then does not work anymore. In all subsequent calls, the drop event is triggered but there is no file in

`` event.dataTransfer.items // empty event.dataTransfer.files // empty ```

This behavior is the same in Troubleshoot Mode.

I am suddenly getting the following error message: "We recommend you use a different browser or disable the “EasyList Cookie” filter from your “Content Filtering” settings (found under “Settings” -> “Shields” in the Brave Browser)." Firefox is now unusable. I have searched "Settings" and can find nothing about "Content Filtering," "Shields," or "Brave Browser." Can you tell me what is going on here?

I've been using Chrome for a long time, and I've been slowly switching over all my bookmarks, passwords, etc to Firefox. I'm running Linux mint for context.

Every time I open Firefox, it opens the home tab, and after a second or two it opens Mozilla Rally in a new tab, and it drives me ABSOLUTELY BONKERS, because I get halfway through typing in a website, and I'm redirected to this new tab I care nothing about, and for some reason cannot get rid of it in the minimal startup settings that actually exist.

That's some straight up Microsoft Internet Explorer sh!t there, and yes that was meant as an insult.

I have not been able to find any reference or any way to make that not happen, and it is seriously making me consider abandoning Firefox entirely. Don't make me go back to Chrome.

Please help.

When I left-click on text and hold the left mouse button, then right-click, first release the right button, then the left button, a "selection mode" is activated, where the end of the selection follows the mouse pointer despite no button is held. In principle this looks like a useful feature (or it would if the scroll wheel worked in that mode, which it doesn't). But at the same time, the context menu opens when the right button is released. So we trigger two features at once, making both less useful, because they're getting in each other's way.

This frequently happens to me when double clicking on a word and right clicking to open the context menu on it. Accidental overlap of the left and right clicks triggers the selection mode.

Can this behaviour be configured (e.g. to use a custom shortcut) or, if not, be deactivated entirely?

I'm using Firefox 123.0.1 on Linux (openSUSE Tumbleweed).
