Diễn đàn hỗ trợ Firefox

As per old thread at: https://support.mozilla.org/zu/questions/1365405 which has since been archived.

As of version 113, this solution is being suppressed. I occasionally see the x appear briefly on the left when a tab is selected, but then it reverts. So far I have not been able to work out what setting is overriding this function, so I've just rolled back to 112 and used the "--allow-downgrade" flag on the firefox shortcut so I can still load my old profile, but understand this is not a safe option in the long term.

I'm currently running Firefox v 112.0.2 on Linux. I've had a theme installed for a while now that I really enjoy. It's a minimalist theme I found on github and then I topped it off with some colors that suite my desktop theme.

The ONLY issue I am having is with the dropdown menus. I can't see any of the list items and I cannot for the life of me figure out where to modify these colors. Searching has only gotten me more confused.

Photo is attached. I'm hoping that changing the text color here is an easy fix. The colors are all fine in other dropdown-ish menus, like bookmark folders for example.

Thanks in advance for any advice.

Newbie question: today I started out using Firefox, so bear with me.

I am trying to set the Firefox Home page to display a limited number of 'pins'. Did manage to get them there, but some other pins are automatically added (based on recent visits I suppose?) So I have 8 pins, 3 I don't want. When dismissing, I get other links instead.

Maybe this is by design and can not be changed.

Vainly search for a way to have only the few pins, that I want, show there, nothing else.

Thanks!

Hi,

Is there any reason firefox would flag an mp4 file legitimately?

• The file extension and file type are absolutely mp4.
• There seem to be no mp4 related zero days.

Does Firefox perhaps just treat all downloads from suspicious domains as malware? Is there a zero day I missed? Is this based on some missing metadata on the file or something?

Thanks for any advice you can give here, I'm scared.

So i was using this website called 9Anime and i was watching a show and i diabled my arrows for going backl 5 seconds and i have looked up everything i can to fix it and nothing has worked. Can anyone help me please ????

Before Update: I have two different YouTube workflows on two different systems. Although I use ONE Mozilla account, I was able to get automatic sign on for TWO different systems. This meant that I was not automatically logged into the other account as long as I was on the appropriate device.

After Update: Auto-login is only working on my main system's Firefox (without new update). I now have to re-log into my production YT account manually. The reason I can identify this was after the update is because I now have an "old Firefox data" folder on my desktop, aswell as all my extensions being re-installed.

Considerations/Clarifications - I do not mean auto-fill passwords. I mean that my account is already ready to go when I access the YT site. - I use a few security extensions. I understand that these may have an impact on my browser's ability to save passwords. However, for the past 7 years, this has never been a problem given similar extensions.

    - Extension List: Privacy Badger, Adblock, Adblock plus, Adblock for YT, DuckDuckGo privacy essentials,  Facebook container, and Decentraleyes.

Any help is appreciated.

I've had Firefox issues for months now. It started after the update three updates ago. Firefox would take 10-15 minutes to load, I often couldn't load websites even after it had loaded....except for a couple of nights recently I've been able to use it flawlessly. Like right now. It's almost 11pm and it's working. I've been through the clear the cache, check if the extensions are slowing it down etc. routine. So why is it working now? It probably won't work in the morning, it didn't work last night, but it worked a few nights ago and again tonight. I'm sorry this sounds so strange but I don't know what to do. I've had to use a different browser for a while but would love to come back to Firefox again.

in the last day firefox has all but stopped working on most websites. i can go to them and they start to load, but then they eventually break halfway through and either end up loading forever or produce an error. if i look at the console i see "Source map error: Error: NetworkError when attempting to fetch resource." this happens on twitter.com and raidbots.com to name two off the top of my head.

i did a complete refresh and even completely uninstalled and reinstalled the browser - it started working for a bit and then broke again. i have no plugins or extensions enabled currently (i have dashlane but this happens with it enabled or disabled). it's making the browser unusable. ive scanned my computer for malware and cant find anything either. i don't have this problem in any other browsers so not sure what else to try.

I completely removed a program from my computer several days ago. The program name still shows in Firefox, settings, general, applications. The program is showing in the applications section in content type and then action shows to the right of the content type. How do I completely remove the program name that is still showing in Firefox, Settings, General, Applications? If I need to go to the registry could you please tell me how to locate it in the registry? Thank you

Hello,

Minor issue but some help would still be much appreciated here.

On some sites, when I click the login field, Firefox suggests a list of possible identifiers. Among the suggestions there is one that is the true identifier I need to use the others are mis-typos that I probably have typed in error some time in the past.

I want to clean-up that list to keep just the true identifier. How do I do that ?

When I go to Settings > Passwords I only see the true login identifier. The other items in the list of suggestions do not appear. So it seems that it is not there that I must do the cleaning-up …

[I am appending an example with a list of login identifiers that Firefox suggests (the correct identifier is the last in the list) and the information that is stored in Passwords (only the true identifier is listed).]

Many thanks.

At some point every night, my Firefox (and only Firefox) reverts to version 111 from the latest version. This happens on 2 different Windows 11 machines.

I can only get Firefox to run again by running from command prompt with "-allow-downgrade" option and then updating again.

I usually don't notice until I launch Firefox the following morning and it gives me a message that the profile was created with an older version and to exit or create a new profile.

I've had Firefox open and then it reverts and it gives me a XULRunner error about the profile being used by an older version.

I don't have any special backup or restore software running and the physical files in my Firefox folder in c:\program files\mozilla firefox are being physically pushed to a prior version dated 3/21/2023.

On both machines, I've completely uninstalled and reinstalled and it's good for a day and then reverts.

No log entries for the reversion can be found. It's just back to a prior version.

I've never come across anything like this before and have scanned for any malware or other issue, but haven't found anything.

Hello Firefox,

I sent a troubleshooting question a couple hours ago to which jscher2000 responded. I was unable to answer his questions from my email as his address was noreply How do I continue a conversation if not thru email?

I can't get Firefox to use some custom cursors. Firefox is only recognizing the cursors that came installed with Ubuntu. Any of the cursors I installed will default to DMZ-White, but Firefox is using those cursors that came installed with Ubuntu. I tried defining the default cursor in /usr/share/icons/default/index.theme but did nothing as well. Also I tried with the cursor in /usr/share/icons and in /home/name/.icons and firefox cannot get in any of those.

I don't know if it's something wrong with my cursors or it's some inner thing with Firefox, any one has a guess? Incompatibility or something missing from the cursor?

Facebook works ok 'till I go to home page and it starts to load and stories or what ever they are called go blank and it continues to reload items over and over. Cleared cache and tried all other browsers and they work ok..

Hi there,

I'm trying to add multi-containers add on to a new Firefox install, it installs, but the icon doesnt show up. It's not hidden in the customise toolbar menu either. Have tried removing/re-adding, but it doesnt come up. It is possible to get to it by clicking the extensions icon, then clicking multi-container, but this isnt very user friendly. Is there a way to resolve this?

Thanks!

Firefox seems to have a problem on Linux using USB Security Keys. I have two Yubico Security Keys which I use for 2FA. The problem seems to be that Firefox cannot communicate with the USB port, as it doesn't make any difference whether the USB Security Key is plugged in or not, the error returned is always the same and the Security Key does not light up.

I believe Firefox's WebAuth code must be fine, as it works on Windows, which is why I think it's some kind of permissions problem. Chrome works perfectly with the Security Keys on my computer.

I've used a number of sites (I've listed a couple below) where you can test your Security Key with Firefox on KDE Neon and the error is always "UnknownError: The operation failed for an unknown transient reason":

I cannot log into Bugzilla with GitHub as my GitHub login uses a Security Key as the second factor.
