My bookmarks are in the list, but URLs which are not bookmarked are also in the list. (I say some of the entries are not bookmarks because there is no blue star if I double click on them.)

Hello, Today, when I first open Mozilla I noticed that I have problems with fullscreen mode. When I use fullscreen (f.g. on YouTube, but it's with all clips in other pages too) I can see white borders (on the left, right and at the bottom). I checked on other browser (Chroma) and I don't have this problem there. Can this problem be connected with new update? Or something just broke and I should re-install?

i cant move the tabs around in the task bar. my firefox version is up to date, but yesterday-ish my laptop forcibly updated itself. its still on windows ten, but thats the only thing i can think of other than installing a kidpix four emulator that may have caused the problem

Hello all,

I am having problems with video playback on some websites (see screenshot attached). The problem is that the video options start to "multiply" - for example, when I start the video there is (as is normal) one 'Speed' and one 'Quality' button, but then every second these buttons start to multiply. This happens only on some websites - for example, it does not happen with normal videos on YouTube, although it happens on YouTube Shorts sometimes.

This is my first question on the Mozilla Support page, I thank you in advance for your help and I hope I follow the community guidelines. Please feel free to leave any suggestions or feedback concerning how I should proceed for asking for help in the future.

Hi, I disabled several options in about:config, and a feature previously disappeared. When I pressed the scroll button in the diamond, it opened a tag and automatically navigated to it. Also, when there was a previously open page, and I open any bookmark (tags), the selected page opens in a new window, I want it. Please help me.

Had the line

.tab-close-button:not([pinned="true"]) { display: -moz-box !important; }

in my userchrome.css which put the close button on all tabs. This no longer works.

Also there is no Close Button (X) on hover for inactive tabs.

In about:config javascript.enabled = True

I didn't change any settings there.

If I place, for example, " "options_ui": {

   "page": "settings.html",
   "open_in_tab": true
 },"

in the manifest.json of the extension, it does open the settings.html page as intended. Problem is that no JS script on settings.html works, be it if it's inline HTML or as a separate file (I tried separate file, as I thought it might be a security thing).

I mean even simple JS such as console.log or

"<button onclick="showPopup()">Show Popup</button>

   <script>
       function showPopup() {
           alert('Hello! This is a popup.');
       }
   </script>"

Other actually installed extensions - their JS on settings pages runs.

I also tried running settings.html as a popup, and I succesfully done so, it's just that once again JS didn't work...

I'm at my wits end, I have googled, I have chatted with the ChatGPT, took me hours thinking it was something wrong with my code... I'm actually making something useful, never done before (it reads out youtube subtitles via TTS, providing ability to still hear original sound, its emotions, no need to look at the screen and it's also a passive language learning type of thing), and it works, it's just that setting page's JS, which I think I need to allow users change speed of TTS and volume of the TTS

After updating from version 112 to 113 - performance has dropped dramatically.

In the beginning the performance after the update was faster than before. But as of tonight and today it's much worse than it was before the update.

I noticed that the browser started using more CPU than usual. Ryzen 7 5800X3D.

Cleaned cache already two times - didn't help. Tried Safe Mode - didn't help.

Your new update, like your last several suck. It is sssllllooowww to load most webbsites. Watching a video is frustrating, pausing every few secons. I am SICK OF EATCHING THAT WHEEL GO ROUND AND ROUND. What is most frustrating is your damned "Update" looser, piggy-backed of of a windows update. I DID NOT want an update, because you idiots cant create a update that doesnt screw up every aspect of peoples browsing or interne5 experience. To m,ake it worse, you cowards hide. There is no way to contact a HUMAN, your help is a bunch of questions that are never answered by [redacted]. Since nobody can write a workable update, Get a job at a fast food joint, and hire people who give a damn, an can actually write something that [redacted] WORKS!!!!!!! I'm on my second ay trying to un-[redacted] your mess. How about sending me an email with a contact to a human with a functional brain. People should NOT have to spendd ays fixing an update that is worse than a virus.

When FF (113.0.1) is maximized clicking on the first (left hand) pinned tab does not open the tab. Hovering over the tab doesn't change the background color of the tab.

If I restore down the window, hovering over the tab changes the background color of the tab from light grey to a slightly darker grey and clicking the tab opens it.

FF 113.0.2 Win 7 64 Bit

When I read a pdf online it gets downloaded even though FF is set to always ask. When it asks I choose open with FF or open with Adobe Reader . Both downloads the file to my download folder. It doesn't ask what foder to download to even though I have FF set to ask where to download to in settings/general

I tried setting browser.download.improvements_to_download_panel to false as here https://support.mozilla.org/en-US/questions/1370494 but it didn't help
