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.

Hi,

I am using Linux Mint 20.3, 64-bit and both Firefox and Chrome are not loading images for me on certain websites (i.e. okcupid). In particular, I am noticing that images will actually load for a split second and then disappear moments later.

I've tried disabling my adblockers, deleting my cookies and cache, running Firefox in Troubleshoot and Diagnose mode, running Chrome in Incognito mode, and evening uninstalling and reinstalling Firefox. Still the issue persists.

I followed the advice here: https://support.mozilla.org/en-US/kb/fi ... s-not-show

Any advice or suggestions would be most welcome.

Thanks, Chris

I have a problem with Firefox not maintaining granted permissions which forces having to re-grant them, re-authorize/signin etc each time (several times a day). The problem exist on several sites (I think they're related, please correct me if not). eg google workspace suite; I'm using gmail in browser, with Calendar, Drive, Voice, and other elements. Having logged in to gmail (which always forces 2fa even though I check "remember this device"), using the other functions of workspace should be authorized, but if I go to say a folder in Drive, or try to create a Calendar event from an email, a new tab opens and I'm forced to sign-in again (with 2fa). All the google addresses I use are in the "allowed" section of Firefox settings, their cookies saved as exceptions for filtering and saved on exit, and allowed in cross-site filtering. I can't think of anything else to do that would prevent having to sign-in all the time. Similarly with other secure sites such as financial institutions, despite having them bookmarked, cookies allowed, checking "remember this site" etc, every instance has to be re-authorized, re-signed in with 2Fa etc. I only ever use the same laptop and smart phone so it doesn't make sense that neither of these devices are ever recognized. I even get email notifications "detected a new signin on an unknown device" etc. and this happens across sessions, before hibernation or shutdown. How do I get premissions to persist?

After installing version 118, Firefox does not automatically explain the pages.I have to go out in the settings and choose the language of the translation every time. The problem occurs after the browser is synchronized. MX Linux system.

With a recent update of Firefox Developer Edition to version 117.0b9 i keep getting extremely annoying popups on all sites, asking me if I want to translate stuff.

I don't want to store unnecessary settings in my browser, related to exceptions to websites/languages that I want vs. does not want to translate.

I want to completely disable translations, globally. Forever. Two questions:

- Why there is no "disable translations globally" checkbox in the newly added popup? - Is there an about:config hack to do disable translations globally, for all languages, for all websites, and forever?

thanks in advance

Same as the question.

The display shows some icons on the last tabs I opened but it seems only some basic website layout is loaded but all the details are gone. Like text, button borders, even the exit, fullscreen and minimize buttons. I have seen that this has been an issue for quite some time before so I am looking if there is a fix or a workaround. I have and Nvidia graphics card and drivers if that means anything. And my swap file is 20 GB and my RAM is 16 so the space shouldn't be a problem. It gets fixed when I turn off Firefox but not when I refresh tabs.

The crazy thing is that when I take a screenshot inside firefox (with firefox integrated screenshot option, like when I press right click and then take screenshot. I can see the text so it seems like it is a display problem but this only happens with firefox and not other apps.

Appreciate all the help. I will ask of ubuntu formums next if I don't find a solution here.

Thank you all for reading and answering!

I'm encountering consistent video playback issues on Firefox while running Fedora 38. The error message I receive when attempting to play videos from certain sites, notably LinkedIn and Twitter (now X), is:

• The media playback was aborted due to a corruption problem or because the media used features your browser did not support.*

Furthermore, when examining Firefox's console while attempting to play a video, I observed the following error:

• [Child 5999, MediaDecoderStateMachine #1] WARNING: Decoder=7fdb3c55a100 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - mozilla::MediaResult mozilla::FFmpegDataDecoder<60>::InitDecoder(AVDictionary**): Couldn't open avcodec: file /builddir/build/BUILD/firefox-118.0/dom/media/MediaDecoderStateMachineBase.cpp:166*

Steps to Reproduce: 1. Navigate to LinkedIn or X (previously Twitter). 2. Attempt to play any video content. 3. Observe the aforementioned error.

Additional Details: - OS: Fedora 38 - Firefox version: Initially 117.0.1, then updated to 118, both 64-bit. - This issue does not occur on Google Chrome on the same system. - I have attempted the following troubleshooting steps without success:

 1. Updated Firefox to the latest version.
 2. Enabled DRM content.
 3. Booted Firefox in Safe Mode.
 4. Disabled hardware acceleration.
 5. Cleared cache and cookies.
 6. Used a Flatpak version of Firefox.

This issue has significantly impacted my user experience, and I hope to find a resolution soon. Any assistance or guidance would be greatly appreciated.

Thank you!

For the past few days, the YouTube website has behaving unusually in Firefox. The volume and play/pause controls don't work. The picture in picture mode does not work. And most importantly, the search bar is broken. Whenever I type something and click the search button or press enter, the value entered disappears and I have to type it all again, only that this process goes on for infinite number of times and so, I can't even search for anything on YouTube.

Firefox used to have an option to put tabs back under the address bar, it is missing. I don't want to mess with custom css files every update when mozilla breaks things again.

Firefox seems to crash repeatedly and generates no crash reports, just freezes up my pc. It works in troubleshooting mode but even after refreshing, the problem persists. Surprisingly, it will consistently crash if I go to `about:support` (except in troubleshooting mode). Any help would be appreciated!

Hello,

I need help i'm using polish language always on many websites.

When i typing letter "ó" which using key combination Right ALT+O always my brower opening "Open file" dialog window. this is annoying always.

Many sites write that it can not be changed?

Why does the browser open this dialog with this shortcut when there is another shortcut for it? Ctrl+O. Why two another shortcut doing te same job?

I am running Firefox-112.0(64bit) on Debian Bullseye. When I pend Firefox I am presented with a blank page rather that my normal sign in page.

Opening a terminal window and starting Firefox with /opt/firefox/firefox generates the following errors:

comp@AbNormal:~$ /opt/firefox/firefox [GFX1-]: glxtest: VA-API test failed: no supported VAAPI profile found. ATTENTION: default value of option mesa_glthread overridden by environment. ATTENTION: default value of option mesa_glthread overridden by environment. ATTENTION: default value of option mesa_glthread overridden by environment. ATTENTION: default value of option mesa_glthread overridden by environment. [ERROR glean_core] Error setting metrics feature config: Json(Error("EOF while parsing a value", line: 1, column: 0))

If I enter a URL the page opens and is usable.

How can this problem be fixed?

Thanks in advance.

been at it a week everywhere. how can I change the resresh rate about 60MH. desktop preferences is greyed out. command line didnt do it. not a programmers, please keep it simple. was hoping a GUI would make life easier. its blocky on a slow screen scroll. tried loads everywhere. I think it might not happen in chrome.

I'm the tech director (tech janitor) for a public school that is using Securly.com for their Internet filter. Securly requires installing their own certificate so they can be a man-in-the-middle. I've installed that cert into Firefox and that works fine. However, even with that cert installed, Sync doesn't work when I'm behind that filter. As soon as I take one of my computers off the school network, everything will sync up. I don't get any errors that sync is failing, it's just not working. Any ideas on how I can fix that issue?

Thanks!

I stream video and after 10 minutes, graying out of screen or simply the steaming stopped. Repeatedly same problems. Problem for same streaming not seen using chrome.

I do online payment and screen locks up. I refreshed... no change. I paid in chrome... no issues Now notified that I may have paid twice. WTF?

Why suddenly problems with firefox.

Running Linux mint

Today when I closed Firefox and reopened it the option to restore previous session was not shown, as a result I have lost half my pinned tabs (I managed to redo the rest from bookmarks) which were vital. I tried going into history but the option was greyed out.

This happened yesterday too but after redoing half my tabs I went to open gmail and it restored all my tabs, I tried the sane today but it failed so am stuck with half my tabs.

Please do not suggest I use synch as I only use one device.

Fix the confirmation email process so it works. Tell me how Firefox lost my signed in status. Tell me why there is an added 1 after my user name of bth73. Drug test your employees for meth usage.

Web page loads incorrectly. so far this is the only page, the same time on other computer all is ok. cookies and cache is clean. Linux Mint 21.2 Cinnamon 5.15.0-83-generic Firefox 117.0 (64 bitu)
