Firefox supportforum

Hello! I am in a work environment and I am trying to determine if there is something in our security systems that is preventing Firefox from running properly. Once Firefox is installed, it works the rest of the day with no issue but almost daily the morning after, it will start to open then instantly crash. When I check the crash logs, it shows in most of them: Modules - Filename: umppc14210.dll Version: 6.28.14210.0 Debug Identifier: B9143DE260194C88AB48EFD6782C9EAF1 Debug File Name: umppc.pdb Signed By: Microsoft Windows Hardware Compatibility Publisher

Some are this instead: Filename: umppc14105.dll Version: 6.27.14105.0 Debug Identifier: CE458B39D37A4C65A60024BBACED6EB31 Debug File Name: umppc.pdb Signed By: Microsoft Windows Hardware Compatibility Publisher

When using the dark theme from Firefox, Google searching seems to break completely as well as some pages will not load which may be related to this.

I have already tried uninstalling Firefox, deleting all of the folders, then reinstalling with a freshly downloaded installer (Even tried the beta one) with same results. It seems potentially MAYBE related to how long ago I closed Firefox before I shut down (Like Firefox is trying to save something to a secure location and times out, then it will work but if it hasn't timed out, then it crashes... or this is my guess)

The Signature seems to change randomly for the crash between crashes.

I really am tired of constantly reinstalling Firefox but I do not want to use Chrome or Edge unless websites require it.

When I try to open any PDF file, I have to Browse to find my pdf viewer (Flexipdf). I do that and also check your "Save this for future" option. Every time I try to open a pdf after that I still have to go through all the Browse steps. I also set up Flexipdf in your Settings and it just gets ignored.

Hi,

I have a fresh installation of my Macbook OS, and a fresh Mozilla Firefox installation. I would like to re-import my old passwords and log ins, but it seems that the new version of the browser doesn't have that option unfortunately. I can see only Import from Other Platforms options, but not import from file or similar.

I have .csv file, but no option of how to import in into my browser.

I would appreciate help on this one. Thank you in advance.

Last night my Firefox 94.0.2 was hacked. When running Firefox, it would lock up my desktop. It disabled Norton Security, it disable other installed security software, and it disabled Windows System Restore. The hacker put up a message claiming to be Microsoft Support, with a phone number to call for help. This was a scam. I ran Firefox refresh, and that removed the hacker's program from Firefox, but then I had to do a full repair of my Window's installation. To protect my system, and prevent this from happening again, I added "xpinstall.enabled = false" into about.config. Please let me know if this will prevent a web site from installing a dangerous hack into Firefox, or if there is something else that I need to do. I have used Firefox for years, and have never encountered this problem before. Firefox is my favorite browser, but I am now afraid to use it. Please advise me what to do. Thanks, Jim

Is there any official or unofficial article/website explaining all the about:config settings? Currently i am trying to pre-edit all my custom firefox settings with the autoconfig.cfg I noticed that dns over https can be pre-edited with the cfg, so im pretty sure the setting: enable https only mode for all windows, which by default is disabled for whatever questionable reason, can be pre-activated via cfg.

How could i do that?

Hello. I want to save my username in websites but not password, so I ended up saving the real username and a fake pwd (and I type it manually everytime I want to login). Is there a way for disabling Firefox asking to update the saved password (but keeping the 'fake' pwd saved)? Thanks.

I have been using Firefox as my main browser for a while and I like it.

I have noticed that some interactive parts on some websites are missing when using Firefox. On the other hand, when using Google Chrome everything works fine.

I am attaching 2 screenshots showing that the button "Start the Chat" is missing when using the Firefox browser compared to when using Google Chrome.

Why is that?

Hey, All of the saved logins and passwords are gone while the bookmarks remain.

I noticed that logins and passwords disappeared after the computer turned off unexpectedly due to low battery and unstable power connection couple times in a few minute interval.

How do I get back logins and passwords?

Several weeks ago, because it seemed to be a Gmail-tab-only problem, Firefox Support advised us to contact Gmail Support.

It is now clear that the problem is with the Firefox browser. The attached screenshot shows an example of an affected tab.

Please fix this. Multiple versions of the same tab waste RAM and other memory, especially on a limited-memory device such as a laptop.

Dear All,

We are working on a project where the page will have a canvas element and page focus will be on canvas element and when users interact, all the key input will be captured using keydown and keyup event and will be sent to the server.

All the normal characters work but composition keys are not working. Even composition events are not getting fired. I tried below example

https://developer.mozilla.org/en-US/docs/Web/API/Element/compositionstart_event

Any help on this will be appreciated.

Thanks

I use the bookmark bar very heavily and my workflow was to just "drag" the tab with the mouse to folder in the bookmark bar, which would unfold and I drop the tab/bookmark in the desired sub-folder.

This worked really well for me, and was fast.

Recently, this stopped working. I can still drop a bookmark in one of the main folders in the bookmark bar. But not in any sub-folder, since the main folder closes as soon as I move the mouse inside it. It is also not possible anymore to move the already-saved bookmarks around via drag&drop.

System: Linux (Manjaro Gnome 41.1) Firefox for Arch Linux 94.0.2 (64bit)

I am not a fan of upgrades. Firefox has been plaguing me to upgrade for weeks so I have. It lost my default tabs when it starts up and for the life of me I cannot find how to set them back. When I open the browser I have 4 tabs that I want to automatically be there. Has this facilty been removed?
