Diễn đàn hỗ trợ Firefox

So, I had an issue updating Firefox where it went into a loop... twice, and ended up re-downloading the Installer both times to force the update onto Firefox. Eventually, when it happened again a while after I restarted my computer, I managed to get it updated normally (after a tiny bit of prodding), without the need to re-download the Installer. But now, I have two additional copies of the Installer on my computer. What should I do? Should I delete the two extra Installer files, or should I not?

Have downloaded the Foxfire browser onto a new desktop and I've signed into my account. I need to see the bookmarks on the homepage as I did on the first desktop. I can see them all, and well organized, in the "backstage", when I click on manage bookmarks. Can you help me get them on the home page?

Die Handybilder(Android) werden beim Abspeichern auf PC oder Stick in Format PDF umgewandelt, sind verdreht und können am Panasonic Fernseher nicht angeschaut werden. (Format unbekannt) Wie kann ich das Umwandeln verhindern? Vielen Dank! Franz Schraut

I've freshly reinstalled Windows 11 and after trying to access and watch a movie on any of these sites I get an error (see the pictures).

Browser version: 137.0.1 (64 bit) Widevine version: 4.10.2891.0

Already tried to disable/enable DRM. Already reinstalled firefox. Already manually installed widevine. No clue what could be causing this issue.

I have two Firefox tabs open on my browser. Task manager shows 35 tabs using 897 MB of memory. How do I make this stop? And why are so many tabs running? I have cleared cache, cookies, etc.

I use Firefox on a ASUS Vivobook running Windows 11. On April 1, it tried to update to version 137.0, but failed and led me into a update loop of sorts. I had to re-install Firefox just to force an update on it, and that worked for a bit. Just today, it decided to update... and led me into ANOTHER update loop, and it's saying that the "install failed" when I check the update history.

Is anybody else experiencing this bug, and is there a way to fix it?

dunno if this is the right board, but here goes...

I discovered a bug with Firefox and the pen/touchscreen on my lenovo X1 tablet.

Using the touchscreen, move the map, map works as it should. Can pinch to zoom, ect.

Switch to the pen, map works with pen.

Touch the screen again and Google maps doesn't respond to touchscreen anymore, only the pen, and refresh does not fix it. I have to close and re-open maps in a new tab.

In chrome, this does not happen. Only in Firefox.

my firefox is taking forever to load any type of page, and in addiition the thunderbird is also slow. I re-downloaded mozilla, but it is still downloading so skow. just last two days, and when I say slow like 2 minutes to open a page. HELP

Firefox 137.0.1, how can I make the scroll bar wider? I tried modifying 'widget.non-native-theme.scrollbar.size.override' in about.config but setting it to 40 made no difference.

I have a laptop ( screen 1) connected to an external monitor screen 2) and extending the desktop. Firefox is running on the external monitor and a site I use has frequent pop up windows with tick boxes to select. With Chrome & Edge I can get the Popup window to open on the external monitor where the browser is running, but with Firefox the pop up window always opens on the Laptop screen. Is there a setting to get the pop up window to open on the same screen that Firefox is open on?

I cannot get supporrt.mozilla.org pages into dark mode. My eyes are not good and I can barely read these pages. I have Dark Reader enabled, but I cannot find any way to enforce dark mode. Is it possiblle and, if so, how do I do it, please?

Hi,

I have vertical tabs enabled in Firefox. What's the way to eliminate this blank toolbar space (see image) Dragging it in the customization settings doesn't work, as it keeps coming back. It's not Flexible Space.

After today's 2025-04 Cumulative Update for Windows 11 Version 24H2 for x64-based Systems (KB5055523) update, Firefox does not allow me to log into my Dominion Energy Credit Union account (see attached login error screen). Using Firefox Private Browsing, however, DOES allow logging in. I have cleared the cache, restarted the browser, and restarted the computer several times. Please advise.

I have an "Ad Blocker" problem for years. I read the instructions "Adblck Plus Instructions" I cannot find "Beneath “Block ads on”, click the large blue toggle next to “This website”, no matter what I do. What am I doing wrong?

in the last couple weeks, every time I go into Firefox my bookmarks and bookmark toolbar are scrambled. (all messed up and out of order). I have to keep restoring from a good save file. How do I stop this from happening? I have even uninstalled and reinstalled Firefox, but that hasn't helped. I have imported the good bookmark file that I saved.
