Komunitné fórum Firefox

When I access the website of UGC ( https://www.ugc.fr/ ) the access page opens up but immediately freezes: the screen luminosity decreases and the pointer cease to function: I cannot acces any of the options: select movies on show, select cinema programmes or schedule, open my UGC account to reserve performances ... Nothing works ... I have tried to reduceprotecton, etc as sugested on Forum and other suggestions: nothing works. I have no problem at all when I open the same website with Opera or with Microsoft Edge ... Why it does not work under Firefox puzzles me. Can you do something about it ? I use Firefox as my defaut internet access without problems for everything else ! This is really strange and most annoying. Thanks for your help.

When I have stories (articles) recommended through Pocket on new tabs that I'm not interested in I will typically "thumbs down" or "dismiss" the story. What I have found recently is that causes them to be promoted to me more rather than less. I believe it's interpreting my interaction as engaging with the content rather than not wanting to see it again. For example, I was shown an article on American football three weeks ago and I gave it a thumbs down. Later that day it was three articles. I gave them the same thumbs down. After repeating this process for days, weeks later I'm still getting multiple articles recommended per day related to football. I've never read one out of interest, and I didn't have any recommendations related to sports until the first one I gave a thumbs down. Based on that, I'm convinced it's having the opposite than intended effect. Dismiss doesn't seem make a difference. Please give me a way to tune the algorithm to what I actually want to see, I like this feature and don't want to have to turn it off.

Mozillers,

I depend heavily in my environmental and other work on Firefox and am grateful for its ability to restore previous tabs when my laptop, not infrequently, stops working abruptly.

Now the much-used bookmarks have disappeared. A search site states promisingly:

"To restore Firefox bookmarks, use the built-in backup feature by going to Menu > Bookmarks > Manage Bookmarks > Import & Backup > Restore, then select a dated backup or a manual file (like a JSON backup) to bring back lost bookmarks..."

But my Firefox's Bookmarks drop-down menu has no Manage Bookmarks option. PLEASE, what must I do?

Elsewhere I managed to find this file which apparently contains recent bookmarks:

"C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles\unk14jlv.default-release-1647366062305\bookmarkbackups\bookmarks-2025-12-26_95_4IdGtYxezJpwuH1UIiT1bRwe1K6bcGO8rv0mqa9rUWU=.jsonlz4"

But attempting to open it with Applications\firefox.exe (default) accomplishes nothing.

FOOL-proof instructions would be wonderful. Thank you.

I am do not get sound using audio recorded with akamai player with Fire Fox browser. I tried the same link using Edge browser and the audio works.

I have tried clearing the cache, but still no sound.

How do I resolve this issue using Fire Fox as my default browser? Is there an audio extension that is needed?

I can't delete the malware "Startfenster. I tried to find help with "Google"-Search. Without any success! This malware exists for me in "Firefox" only. Other browsers are not affected. Perhaps anyone can help me... Thank's!

can not resolve repeated problem : "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem." Cánt not find "Refresh"

I have various shortcuts saved on the shortcut page comes up after logging in. Its set to 2 rows.. I use it every day. Used it this morning and working perfectly. Been out and when I came back the page is totally blank. I've tried sytem restore to 5th October but makes no difference. I use Windows 10 and read that Firefox are continuing to support Windows 10 I'm visually impaired and use a desktop PC with a large screen. I'm not PC techically knowledgeable. How do I restore my shortcuts or how do I re create them?

Where are my shortcut tiles? I used CCleaner and they all disappeared and I can't get them back even though I make sure they were on and have 2 rows selected and restarted my computer since. This happened last week and still no sign of them. See pic for reference.

I am getting the following error message when using Firefox. The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem. I cannot see my bookmarks or add new ones. I followed the directions in articles about this problem and they did not. help. I decided to uninstall Firefox and l re-installed it from scratch and i still get the same error message.

Hi, Since the last update for Mozilla on the laptop (updated on 6/Oct/2025 - version 143.0.4 (64-bit)), all the shortcuts to websites in Firefox homepage I had pinned have disappeared. Also I can't add new shortcuts. I already have shortcuts enabled in Settings>Home>Firefox Home Content>Shortcuts.

Does anyone know how to solve this?

Kind regards.

I’m running into a limitation with Firefox profiles involving the original Profile Manager (about:profiles) and the new Profiles menu in the toolbar.

I previously created multiple profiles using the original Profile Manager (about:profiles), for example profiles A, B, and C. These profiles still function normally and can be launched through about:profiles, but they do not appear in the new Profiles menu in the toolbar.

I also tried using the “Copy this profile” option available from the new Profiles menu. This made it clear that the feature does not work with profiles created via about:profiles. For example, when I open profile A, I expected that I could use “Copy this profile” to copy profile A into an existing profile like profile B (which was also created using about:profiles). However, this is not possible. Profiles A, B, and C remain isolated from the new Profiles menu and cannot be accessed, copied, or managed through it.

At the moment, profiles created with the original Profile Manager (about:profiles) can only be accessed through that manager and cannot be transferred into the new Profiles menu in the toolbar.

Is there an official fix or a workaround that achieves the same result—specifically, transferring or integrating all existing profiles created with the original Profile Manager (about:profiles) into the new Profiles menu accessible from the Firefox toolbar?

1. The browser's built-in full page translation function has poor translation performance, even far lower than other browser functions.

2. The font modification in the settings cannot take effect on the translated page font. For example, when opening a literature page (Elsevier) and clicking on the built-in full page translation, the font does not change.

3. When the page becomes a fixed tab, the prompts before closing multiple tabs will become invalid, and clicking the close button will close all tabs without prompts.

It should be pointed out that the loading speed of this browser is very fast. I feel that using this browser fully utilizes the performance of my computer, rather than some browsers that use a new era CPU and GPU, but the loading speed is the same as more than a decade ago. In addition, this browser has highly personalized features that meet my needs. It would be even better if the above issues could be resolved.

Thanks a lot！

I have installed an animated theme for my home page a while back, but recently if I minimize firefox the memory usage increases until it freezes my pc completely. I know this issue has been reported as Bug 1828587 2 years ago and it is said that it is fixed, but here I am experiencing the same thing. I would appreciate any help since I am not that good at coding a css file. Here is my userContent.css code if maybe i set something up wrong:

@-moz-document url("about:newtab"), url("about:home"), url(about:privatebrowsing) {

   /* Sets background image and autoscale image to browser window. */
   body {
       background-image: url("wallpapers/wallpaper.avif") !important;
       background-size: cover !important;
       background-repeat: no-repeat !important;
       background-attachment: fixed !important;
       background-position-x: center !important;
       background-position-y: bottom !important;
   }

   @-moz-document url("about:newtab"), url("about:home") {
       .top-site-outer .title {
           color: white !important;
       }

       .logo-and-wordmark .wordmark {
           fill: white !important;
           color: #00aaff !important; /* fallback for text */
       }

       .context-menu-button.icon {
           fill: white !important; /* for SVG-based icons */
           color: white !important; /* for any text-based fallback */
           opacity: 1 !important; /* ensure visible even when normally dimmed */
       }
   }

The second part is to make some of the text on my homepage white so it is visible.
