Hi,

I'm using FF on Fedora 39.

However Firefox does not remember any file associations. The MimeTypes.rdf file in the profile is missing and is also not created on restarting the browser.

In the options I've now set the configuration to "Ask whether to open or save files". Now I see a popup when clicking on a file however there is no checkbox with "remember this file associations" (or something similiar).

I'm having trouble with Firefox where images aren't loading on some websites, even though they display fine in other browsers. I've tried clearing the cache and restarting Firefox, but the issue persists.

Is there anything else I can try to fix this problem and get images to load properly?

My customer has a problem since about a month on Firefox (using it on a Terminal Server). The top of Firefox gets hidden by white and grey "bar" and he can not even use the "functions" of buttons behind that. -> Please see attached Print screens Lower part of the Favorites-bar is visible and also works if he clicks on it - everything above not visible and does not work for clicking.

The problem only comes up from time to time maybe once or twice a week. When he minimizes Firefox the application behind is visible normally. when he maximizes it again, same problem still visible in Firefox. When he closes RDP Session and reconnects - the problem disappears. When he turns off the monitor where Firefox is visible - Firefox gets move over to the other monitor and the problem disappears.

I am not 100% sure if this is a Firefox problem or Remote Desktop Problem (or maybe an add-in problem). But until now it only happened on Firefox!

He is always on the last recent version of Firefox, we just updated today to the latest version again - but I can not say yet, if the problem would still exist on the latest version from today.

Recent issue, April 2024. Had version 124 Firefox on Win10 computer and went to Help - > About to have Firefox check for updates. This has worked just fine up until now. The message "Failed to check for updates." is shown in the About screen. I have uninstalled and re-installed Firefox with the same results. Have also un-installed Firefox, un-installed Mozilla Maintenance, then removed Firefox data from App Data folder in user directory, then re-installed with the same results. Also, now when I access a local media server, I keep getting the message "Firefox is installing components needed" and that never goes away. Any ideas?

I use firefox on fedora 38 and after update firefox about a month ago . i got this error when use private mode ,for thai languge it just error but in normal mode it ok .

The pinned shortcuts on my newtab page have all disappeared once again. I've gone to about:config > browser.newtabpage.pinned and my shortcuts are all listed. But only blank boxes show up on the page. It will not accept a new entry when I try to enter one. It goes back to the blank white box. Why does this keep happening? Can anyone give me a Firefox for Dummies way to fix this?? Thanks!

When the little yellow man is placed on to the map, and a direction arrow is clicked, the view just continues to spin round. Clicking on the 'X' in the top right hand corner terminates street view. This does not happen with other browsers.

My OS is Debian 12, Firefox is the latest version 115.9.1esr (64bit).

We have an electronic document management system in our company. The system is an internal system without access to the LAN. Firefox detects files downloaded from it as potentially dangerous after the last update. Is there a way to prevent files from this website from being detected as potentially dangerous?

I have a well hidden web server that uses HTTP. I need to download files from that server. After the newest update, Firefox now gives a warning about the website and on that warning is a button to "Allow Download". However when I click on that button, the file that gets downloaded IS NOT the file that I was initially attempting to download. It looks like it is a copy of the web page that was being displayed at the time. I noticed this behavior at work. I went home and used Firefox to connect to the server and everything connected and downloaded correctly. I went to see what version of Firefox was running. It was 124.0.2 and there was a button saying "Update Firefox". I clicked that button. My home Firefox updated to 125.01 and my home version of Firefox now also downloads the wrong file.

I am using Ubuntu 23.10.1 with KDE Plasma desktop environment. Since recently I've been experiencing the following problem with Firfox document viewer: after a period of inactivity, PDFs become unreadable, and seem to cumulate everything that was displayed on screen (see screenshot). Ctrl + F5 does not help, and neither does closing the window and opening a new one with a link to the file. KDE Document Viewer displays the same file correctly.

I've been using the Firefox browser, and recently when downloading files with Firefox, sometimes it prompts: .part could not be saved, because the source file could not be read. # see image #1 I'm trying to download file to disk D. But the fail tips is download .part file to disk C. Maybe firefox is using some file cache policy which I don't know. I also checked both two location, my account have read/write access.

I can try to resume the download, and the download progress will increase, but about half a second later it will fail again. If the file is small and my internet speed is fast enough, after several attempts the file will eventually download successfully. # see image #2 I have tried using "private window" or enter "about:profiles" to create/use a new and clean profile, but the issue still persists. # see image #3 I tried using other download tools like "Internet Download Manager", and the download was successful. It's ok for use chrome to download the same file to same disk location. The problem recently emerged, it didn't exist before. At least a month ago, the same computer didn't have this issue. I'm not using parental controls.

I'm using the OneTab add-on, Enabled. The icon no longer shows on the Toolbar, though it is on the Menu bar next to Firefox View.

I ran Remove and then Added it again, hoping the Toolbar Icon would reappear = no go, And I lost all URLs already saved, stupid me. To be clear, clicking the Icon on the Toolbar saves all open tabs.

Is there a fix via Preferences? Thanks. gw

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?

When trying to install any extensions on either the Mozilla Addons website or directly via the Extension settings, it fails to do so.

I've attached a screenshot of the Mozilla Addons website when it fails to install the extension. On some other addons that I've attempted in the past, it just shows the throbber forever.

I have checked the Multiprocess Browser Console and it says that it fails to move the file because it's locked (NS_ERROR_FILE_IS_LOCKED). I have also attached a screenshot of that.
