Diễn đàn hỗ trợ Firefox

I had the PC at Staples to get malware removed. They also removed the AVG Anti-Virus and installed McAfee Anti-Virus instead. When I got the PC home, many of my Firefox settings had been changed, I don't know by what or whom. And my Greasemonkey and Adblocker extensions had been removed. I reinstalled those, but now cannot get my two desired scripts for Greasemonkey to download, let alone install. I also now have a message, "your browser is being managed by your organization." But this is my own PC that I use for both work and personal purposes. I've tried all the recommended approaches for removing the "organization" message, to no avail. Tech support from McAfee recommended removing and reinstalling Firefox, but I don't know if that is likely to fix the problem, and I would lose all my bookmarks, some of which are important for my work. I don't know how to save the bookmark links before trying to uninstall/reinstall Firefox. Need help.

The fonts are weird for some pages. I have used the following settings: Fonts for: latin, Proportional: Serif, Serif: Default(DejaVu Serif), Sans-serif: Default(DejaVu Sans), Monospace: Default(DejaVu Sans Mono). Also I have checked the box "Allow pages to choose their own fonts, instead of your selections above".

Need help to fix the issue!

Only for some selected websites. I get this on Lowes.com too

I used to be able to open a password protected pdf email attachment on my laptop without downloading it. Now when I enter the password, a file loading symbol appears but the file never opens. On other browsers and on my android I am able to open the pdf. How do I fix this situation?

I have been using Firefox for many years. Suddenly I cannot get any sound from videos in Facebook, YouTube or anywhere. The settings in Privacy --> Permissions --> Autoplay are set to "Allow Audio and Video". There is nothing wrong with the computer as I can play videos and sound files on it with no problem. Sound is no problem on Internet Explorer or Microsoft Edge. It is just Firefox that after years of use the sound as stopped working. Can anybody help?

So I can not play audio from any website in firefox. I updated, refreshed, used troubleshoot mode, and unistall & reinstalled. Nothing works. I know it is not my PC because the sound works on every other app, just firefox wont play audio PLEASE HELP

Recently I am continuously proposed to install updates. I do that, but I think the installation may fail, because immediately after restarting Firefox I'm proposed to install a new update. I have Firefox set up to download updates as soon as they are available.

The version I'm using is 104.0, which should be the latest one available for desktop, therefore I don't understand why the browser is trying to load again the update.

Latest Firefox update 104.0 started displaying "This connection is not secure. Logins entered here could be compromised" again after previously being disabled. It's an annoying message that pops up on my intranet logins and I want it disabled again. I did the usual in about:config and set security.insecure_field_warning.contextual.enabled to False and security.insecure_password.ui.enabled to False like previously, but the message is still there. It seems that latest update is forcing this message and ignoring the settings to disable them. Please help!

Lately I've been seeing Firefox apparently shut down all on it's own. Most times it would happen right after opening up a PDF attachment in our Yahoo webmail email with Adobe DC. I thought that by clearing the cache and history this would fix it. It did not. The only thing that seemed to work was to open up the PDF using a browser instead of Adobe. I thought that it might be an isolated case since it was only happening on the office computer. I was using a different computer this morning and it happened on this computer as well.

I ran Firefox in 'troubleshoot mode' and it didn't make any difference. The only thing that seemed to make a difference was to open up the PDFs in a browser instead of Adobe Acrobat DC?

Recently (last month or so) I noticed a new behavior: when I receive PDF attachments via Yahoo e-mail, if I open them using Adobe Acrobat DC reader, and print them, after printing the Yahoo e-mail tab closes. So I have full functionality -- can open the PDFs, print them, everything good -- but then I have to restart Yahoo e-mail. Big pain.

This behavior is occurring on all three of my PCs (two laptops and a desktop), all of which are running latest Windows 11, and latest Firefox, and latest Acrobat reader.

Hello guys, this would be a little awkward. Since I've run into this problem a limited number of times and I can't reproduce it. But it does appear frequently and is very annoying. I had to ask here for advice and help.

The device I use is a MacBook, running the official version of Firefox, and as far as I know this problem has been there for at least half a year. I'm used to keyboard operations, usually I use Cmd+T to create a new tab, then the cursor is focused on the address bar, and I type the URL. Since I'm typing an address that I visit often, maybe I just type the first few letters, the URL gets autocompleted, and then I just hit enter and the page opens in my new tab. But sometimes I hit enter twice (eg not English input method). At this time, I noticed that in addition to the URL I wanted to open, there's an additional tab. This tab was blank, or the page I just visit.

From my personal understanding, I may have performed the above operations to create a new tab or clone a tab at the same time. But I don't think my operations will cause these to happen concurrently.

Below are the extensions that I have installed, in my impression I don't get this bug in Windows, but I don't use Windows a lot. In addition, my MacBook keys may be sticky, or it may be a system problem.

Updated a month ago and discovered all of my password stored history in FF is gone.....

I have seen that this happened to others but despite efforts, unable to restore all my passwords after the update despite that it says this will not happen.

I have followed the steps of profile, sync but nothing.

Afraid to ever update again and never had this issue in many years of using ff.

I am running Unix Ubuntu 22.04 with Firefox 104.0.01 (64 bit). My Canon LBP 6230DW works fine in my word processor and in Chrome, but it does not show up in the Printer destination field when I am in Firefox. The only print option is to "Save as PDF." How do I get the Canon to be a print destination in Firefox?

When using GMX and trying to open the Cloud screens I keep getting a Warning screen and the page won't open and then I am logged out of my acct. I have attached a pic of the screen print as I cannot seem to add the screen print in the system. I need help to correct this issue.

Thanks Shirley

I did a full reinstall of my Firefox browser because of a problem where it couldn't load some youtube diy videos (that did load in another browser). Before the reinstall I made bookmark and saved logins backups. No problems with backup/restore of bookmarks.

Exporting saved logins works perfectly and I get a readable csv file , but importing simply doesn't work. First of all the import feature was disabled by default (?). After making the change in the settings and restarting Firefox I see the 'import from file' option in the password manager.Big dissapointment however when you click the 'import from file' option and select the exported csv file because nothing happens ! No error, no result,nothing ! I tried several csv files from earlier backups but none work. Google on the other hand can import all of my csv's without any problem ! Any help on that would be greatly appreciated.
