In Firefox, the mouse becomes partially unresponsive to elements in the browser and on web pages. This happens after 15-30 minutes after starting up the browser. Common symptoms include:

- Unable to drag and drop elements properly, including text after highlighting it. - Sometimes, the mouse continues to hold elements while dragging. Pressing ESC temporarily fixes this. - Dropdown menus on websites do not drop down when hoovering over them - Other items on websites don't display items when hoovering over them

I have tried:

- Different mouses, including my laptop's trackpad - A Firefox fork, namely Waterfox, but it still occurs - Limited testing with other browsers. No problem occurs - Limited testing on desktop. No problem occurs - Entering Troubleshooting Mode on Firefox - Clearing cookies and cache - Reinstall Firefox (including installing from command line instead of the snap store) - Updated Firefox - Refreshed Firefox - About:Processes doesn't show anything using more than 10-15% of CPU at any one time - Limited testing with a new Firefox profile. No problem occurs - Disabled WebGL and Hardware Acceleration.

Temporary fix: Restarting Firefox, but the problem re-occurs shortly after use.

Using Ubuntu.

Any help would be greatly appreciated.

I really want to use firefox. I really do. But firefox's memory management is making that very difficult.

I have 8GB of RAM, which really ought to be enough, but inevitably, over time, firefox will munch and munch and munch until it has consumed all of it.

And then... my system crashes. I lose work. I get angry.

Well, okay, I use linux, so after this happened a few times I stuck firefox in a systemd scope and limit it to 90% of the memory of my system. At first, that didn't work because firefox would simply eat into the pagefile, until it had consumed all of it (or as much as I entitled it to), at which point firefox would desperately try to do.... something, very frantically, which would lock the CPU usage to 100%, again bringing down the system. So I limit its RAM and prohibit it from using the pagefile, and now, it's just firefox that dies.

....

But, really, that's still a problem. I still have emails partially written, forms filled out, work is still lost. Is it really so abhorrent to take out the trash that you'd rather just commit suicide instead? I say take out the trash, because firefox will restart, reload those very same tabs, and carry on with a fraction of the memory usage. Something's been dropped, and it wasn't important (well, other than the content of that email I've been composing for the last half hour).

So. If I'm going to continue using firefox, which I would very much like to do, there needs to be some way for it to gracefully say to the user: "I've run out of available memory. I'm going to have to..." (for example) 1. perform garbage collection (do whatever 'minimize memory use' seems to do... which is not much, but something that really ought to be the default action in this situation) 2. clear the buffer of some videos being played, or some cached results or something, i dunno. 3. gracefully stop loading the current tab, or process, or whatever, and say to the user "I've run out of resources to continue. Please choose one or more tabs to close in order to continue"

Then, at least, I can sacrifice my background music tab, or something else unimportant, to buy enough time to copy that email into notepad, submit that form, or just run 'minimize memory usage', and be able to carry on.

Hi, when using the --search option with firefox in the command line a new window is opened regardless of whether the 'open in new tab instead of new window' option is checked in settings or whether the --new-instance option is added.

Is there a way around this? I'm trying to have a command that would make a search in a new tab of the current instance of Firefox.

Thanks.

This happens at random intervals, mostly when firefox is being left idle.

Since it starts >1000 threads, it easily fills ram and swap, then get killed by OOM killer. Hence no crash reports.

I'll upload a gist with OOM details from dmesg and journalctl, if there is a way to get debug info for this, please let me know.

There is no gear icon when I open a new tab. and my thumbnails are missing. Tried the solution here Right clicking does not give the option to restore defaults. value of browser.newtabpage.enabled is true. changing it to false did not change anything, neither did changing it back again.

I want Firefox on my action (button press or keyboard shortcut) run shell script or program of my choice and giving it as parameter the url of the actual web page I'm seeing.

Is it even possible?

i cannot get the mic and camera to show in firefox any and chromebook versions including full desktop version linux, all settings enabled firefox.

on option in sttings , let website ask to use camera or mic,  hello id like voice search and vid conf but i cant enable it, works fine on mobile phone. so the user cannot use his computer in those 2 features unless a website requests it, what a stupid setting really

I am using Firefox 115.3 on Debian 12.1. I have numerous tasks which require the use of my web browser and have allocated a different virtual desktop for each. This means that my browser session typically has several dozen tabs open in numerous windows at one time. Under normal circumstances, this works just fine (and is a testament to the engineering that has gone into this browser).

My issue is that Firefox renders my machine virtually unusable for a few minutes each time I restart my desktop session due to focus stealing. When I open the browser, several dozen windows pop up (as expected) and relocate to their correct virtual desktops (as expected); however, as the windows begin to load, the most recently active Firefox window steals focus repeatedly. If I am, for instance, in the process of typing my password into my desktop e-mail client, a Firefox window may steal focus from the password dialog. In practice, this focus steal happens once every few seconds for several minutes.

I would prefer that Firefox would not steal focus while restoring a session. Does anyone have any suggestions for correcting this issue?

I'd really like Firefox to use my X selection buffer, or, if that's not possible then stop supporting shift+insert because the inconsistency is jarring.

In a terminal I highlight then use shift+insert to paste, but when use shift+insert in Firefox it pastes my copy buffer rather than my selection buffer. So I copy something from the web, then use shift+insert in my terminal because I'm used to that now, and I paste the wrong thing in. And I highlight something in my terminal, switch to Firefox and use shift+insert to paste it, and it pastes the last thing I ctrl+c'd.

If shift+insert did nothing in Firefox then I'd get used to it, but the switching back and forth is something I stub my toe on every day. Does nobody else feel this pain? Please fix it!

Hi,

I'm on Arch Linux and use uinput to create key events. It works reliably for >12months in all applications and under all circumstances except in Firefox where some key events are skipped non-deterministically. My test case is:

in a text field, emit `<ctrl down>a<ctrl up>123456789987654321<left>...<left>` with 9 times `<left>`. Sometimes a 9 is missing and sometimes the cursor is further to the right than expected.

This happens every 8th try or so, which is too frequent to not break the user experience.

What I have tried: - multiple PCs (2 with this issue and 1 without) - Troubleshoot Mode - `window.onkeydown=(e)=>console.log(e)` (events are missing)

Since I've only ever seen repeated characters/keys disappear and never when writing manually, I would guess there is some kind of event cleanup algorithm kicking in. (the events are emitted without any delays)

I would really like to fix this issue because Firefox is my favorite browser. Any idea how to track it down?
