Firefox Support Forum

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.

Hello,

you have disabled the Speed Dial add-ons without any further information, plus you didn't add or do some way to restore the saved tabs in this add-ons!!!!

I have many important website added there and now i cannot recall the name!!!!

i need to know what is the way to have what was my saved website?

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?

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.

As described already, Malwarebytes has picked up a Trojen on Firefox outbound, Below is what Malwarebytes has described: Malwarebytes www.malwarebytes.com

After creating a new Windows User account and switching back to original account, I lost ALL of my Quick Access Bookmarks! Then I did a Bookmark Restore using the most recent saved Bookmark file and I lost around 64,050 bookmarks!!! Now, the latest saved Bookmark file lists 5 items. This is a ridiculous and a very serious issue!!!

What is going on? I spend a lot of time getting important Bookmarks for research, and etc. How can I get all of my Bookmarks back? Apparently, I cannot get them all back. See attached file.

94.0.2 (64-bit) Win10

Hi folks! Is this a bug?

Image1 with Firefox. Image2 with Edge.

Do you see how the (white) title bar crosses into screen2 when it's maximized on screen1 ? Firefox is the only software that does this.

Gracias por la help.

Hi,

I have been using Firefox sync for many years now. I just got a new computer and when I tried to connect with my account, I received a message saying Firefox has locked my account.

Would you please fix this asap? I use your browser to work and not having my account back would force me to switch to Chromium, which I don't want to. Please note my account and my email address are both legit. Thanks

The List of Cookie exceptions under Security Setting, the ones I want to retain, keeps getting deleted. I select ALLOW for each one. What is causing the list to get deleted?

I recently joined a paid instructional website. There are several videos that I need to watch, but when I start to play any, a green bar covers part of the video. How do I get rid of it? This doesn't happen with YouTube videos, btw.

Firefox always crashes when I download a file. After that, when I reinstalled firefox again, the situation did not go away, but it was fixed only after restarting the computer.

I wonder if this was due to hardware or software error? I recently renewed some computer parts.

Any help would be greatly appreciated. Thanks!
