Hi, It seem that the Firefox.exe was hacked on my PC. Namely, there is no way to get rid of some Turkish webpages like https://www.ahaberci.com/sifresiz-trabzonspor-konyaspor-canli-izle-bedava-bein-sports-1-canli-yayin-izle-justi-49375h.htm which appear on starting the Firefox. I checked for the malwares the PC with several antivirus software. I uninstalled Firefox and reinstalled it without saving data from the previous versions, with no success. I tried all methods offered by the Firefox Help, but does not work. Please, help me to fix the problem. I am attaching screenshots to illustrate the problem.

Thank you, Katalin

I want to use HTTPS-Only mode, but Firefox enforces it on my private network as well as the public network. Because I do not have certificates for any of my private network hosts HTTPS-Only mode blocks all internal network traffic. The suggested temporary workaround is impractical. Is there a way for Firefox to check the hosts file for a local name/ip or is there another fix for this?

Firefox is crashing almost immediately after loading a page. Sometimes it crashes while loading the page, sometimes I can scroll down or click a link, and then it crashes. Biggest issues are on Reddit. I'm able to browse the Firefox support pages with minimal issues (although it has crashed once or twice).

Crash happens in Safe Mode. (I'm in safe mode right now and it just crashed) I did a FULL clean install about a week ago. (actually did it twice just to be sure)

Not sure what info you need in order to help, but here is some of the crash report from the latest one today.

Hello, for the past week i've been tackling this problem and it's driving me nuts. I've basically replaced FF with Chrome at this point, because I can't use it for work.

Firefox refuses to print, no matter which printer I select, and even if I try to print to .pdf using Microsoft Print to PDF (or other, 3rd party ones, I tried). Other programs and browsers print just fine, it's only FF that refuses, and it refuses to do so with any printer, physical or virtual.

The error I get is a window titled "Print Preview Error" and the error message is "An error occured while printing" (see attached image). For what it's worth, when I go to the menu and select Print, I get the print preview just fine, it's only after I move on to the printer selection and click on Print that I get this error.

I've followed all the steps from: https://support.mozilla.org/en-US/kb/fix-printing-problems-firefox as well as: http://kb.mozillazine.org/Problems_printing_web_pages#Reset_printer

And I've also tried using Safe Mode while doing that, as suggested here: https://support.mozilla.org/en-US/questions/854093

I hope you can help! I've been a Mozillian for more than 20 years, contributor, and volunteer, but this is making my work impossible and I'm forced to abandon FF due to this problem.

Hello, I always download mp3 files inside webs using "Save as" and ".mp3" method. Sometimes I had to explicitly save filename with ".mp3" extension to force audio download. However trying to download an audio no matter what format I write in file always download only webpage as .html never as .mp3. Looking at sourcecode (image attached) I found a detail containing "chrome" in webpage. Later, I tried downloading with Chromium at it worked properly. Does anyone know how to download this from Firefox?

Thanks in advance for your help. P.D. I am using Firefox 84.0.2 (64-bit) for Ubuntu canonical - 1.0.

Upgraded from v.60.9.1 to 68.12.1 finally. Everything works, except nothing happens when selecting any of the dropdown menu items under the "Thunderbird" entry at the top left. This is the one that offers "About Thunderbird", "Preferences", "Quit Thunderbird". (see image) None of these work - all the other dropdown elements under "File", "Edit" etc. work fine. Had to close the program by the keyboard shortcut, but could not see the Preferences at all. Is this a known issue? Mac OS 10.10.5, which I know is old, but v68 is supposed to be compatible. Restarted computer but no difference. Went back to v60.9.1 and the former profile and that works as before. Advice?? Thanks.

Hello!

I am using Firefox on my notebook with external monitor.

When the external monitor is set up as the main display and above the notebook monitor, the toolbar popup menus in Firefox are cut off on the notebook monitor (≡ & addons like uBlock etc.), so only a small upper part of them is displayed. The ≡ menu can be fully operated in this case because it has scroll bars, the addons' menus do not.

If the notebook monitor is set up as the primary monitor or is not below the external monitor, the problem does not occur.

Disabling all addons does not cause any change.

The problem does not occur with other browsers either.

Would appreciate some help!

After using CCleaner, on opening FireFox I discovered an unwanted, 'other bookmarks' tab sitting on my toolbar. It won't move (click & drag), and I want rid of it. I like having the double right arrow at the edge of the toolbar like it use to be. When I did a full browser 'refresh', it disappeared!

However, on using CCleaner again, the darn thing reappeared.

How to I tell FireFox that I would like to be in charge of how it displayed, rather than some errant code that someone else thinks i want?

hi guys. My computer was running slowly, so I ran the reset programme as you recommend. You say that this doesn't affect stored passwords - but I've lost every single one of mine. and worse, it doesn'tseem to be saving any new ones either.

many thanks

I have posed this question under "Fix slowness, crashing, error messages and other problems," and under "Other," and have not gotten a single response. So I am trying it again here.

This is a major glitch, and I am surprised that no one else is dealing with it too!

Is there anyone who works for Mozilla who monitors these forums who can help?

=========

After upgrading to FF 84, my previous sessions are no longer saved and restored unless I restart in Safe Mode.

- I have Restore previous session checked in Preferences.

- I have opened new windows and tabs and one by one disabled and restored every add-on that I have had enabled and quit and restarted each time, until every single add-on has been disabled, and still the previous sessions are not saved and restored.

- I have looked in the sessionstore-backups folder with each restart, and there is never any file for the previous sessions in it.

- I have cleared all my cache before quitting and restarting.

- Again, even when there are absolutely no add-ons enabled, the previous session is not saved and not restored.

- Again, only when I restart in Safe Mode is the previous session saved and restored.

What is the solution?

I use Firefox for work and I have a site that has a pop up window that shows me alerts. When I use this site on Edge or Google the site makes either a sound or blinks in the taskbar or both. On Firefox I cannot get it to do either of those. The site seems to work best in Firefox but I need an alert sound or visual to let me know there is an item for me to review. I have gone into settings and tried to change things to make this happen with no luck. Any help would be appreciated.

Hey there!

We have error logs being created fairly regularly for user(s?) with a particular Firefox extension. We are trying to identify this extension to determine the cause. I know a reverse-lookup (ID to name) service exists for Chrome extensions. Is there something similar for Firefox extensions? Thus far, I haven’t been able to find one.

The extension ID/source in question is: moz-extension://ba9d01f7-5cbf-442b-94bf-f030a6fdc626/scripts/uninterrupt.js

Any insight that can be provided would be much appreciated.

Thanks!

(I originally posted this in the discourse forum, but this forum appeared to have a larger audience, so my apologies for the blatant cross-post... but I'm kind of at a loss here.)
