Diễn đàn hỗ trợ Firefox

After Installing new system on my laptop and singing in to my Mozilla account nothing was restored from it. Everything is empty as it is completely new account but I created this one few years back and never had a problem with a sync. Hopefully it will be restored since I had large amount of important bookmarks. If you can check and resolve it please. Thank you.

When I turn on my Mac and click the Firefox browser icon, it will not load. It hangs. I get a "not responding" message and have to "force quit," again and again until FINALLY it loads, after five or more failed attempts. This does not happen with Firefox on my laptop, only my Mac. Both Firefox and my Mac are up to date. Why is this happening? Please help. It happens every day when I try to load the browser. I am about to give up and move to Safari. Relatedly, anyone know if it's possible to export all my bookmarks from Firefox to Safari?

This is happening more frequently. sometimes clicking links works but the cursor will not respond if i hover over the new tab button. To continue I have to select a new firefox window, The unresponsive window remains in error even when a new working window is active.

you asked me to change my profile, choose a color and I did. But when I wanted to Firefox, all my old password and bookmarks had disappeared. I want them back if I am going to continue to use Firefox as my favorite browser.

Hello I got a pop up or it was new tab informing about new firefox functions. It was about profile creation and management. Now i have two profiles and cant switch back to my old one. I cant seem to be able to delete new profile to return to my old one.

I just bought an HP Omnidesk M02-0085m PC running Windows 11 Home edition. For some reason Prime video works in other browsers, but in Firefox I get audio and a black screen. I am not using any ad blockers and I have tried toggling performance settings on/off. Any suggestions?

I have a chromebook with linux enabled and installed firefox according to mozilla's instruction - via the sudo get-apt command. The cursor changes from the default to a very small adwaita. I've spent hours googling this issue and everyone I've come across had used some third party repo or was trying to shove in their own custom cursor theme. Literally all I want is my regular cursor back, and I have no clue why mozilla would have a specifically set cursor for their browser instead of just having it default to os. I don't really know what I'm doing here, but I cannot begin to state how tired I am of messing with this dead-end issue.

Using Firefox 145.0.2, Flatpak installed via Bazzite's Bazaar store, there is no "sparkle" button in the sidebar, no options present like there are when I use Firefox on Windows.

Crash submitted, ID = 320cc808-4505-4cba-6e0f-9f2c2955d007 Still happens in troubleshoot mode. Still happens with extensions disabled (Ublock origin, Proton Pass) Started happening since Dec. 5, 2025 System is current with all Debian?Ubuntu updates installed (daily refreshes) Linux Kernel 6.8 on Lenovo Yoga i7 (ca. 2022) with Intel i5 & Intel graphics

Lost my audio on Firefox. All movies and web site videos SILENT

Strange exceptions: e.g., can't ear video on youtube.com; BUT, CAN hear it if web page has LINK to YouTube!?!? SOME Twitter videous have audio; others are silent

How do I turn Firefox audio back ON?

I'm running 145.0.2 on Mint Linux and Windows 11...

Like many other users, I have an issue in which roughly half of the icons representing bookmarks on my Bookmarks Toolbar have been replaced by the black+and+white icon of a globe. The links work, but because most of them are now the same, it means I have to hover over them to make sure I click on the link I want.

I've tried: Exporting all my bookmarks to HTML; deleting all bookmarks; re-importing Deleting the "favicons.sqlite" database and letting Firefox recreate it Creating a new Profile and importing all my bookmarks "fresh" in to there

Not only does none of this seem to work, the results are actually inconsistent.

This problem has been kicking around for years - certainly for many major releases of the browser. I understand that there could be deep/complicated issues such as a corrupt user profile, for example...

Unfortunately, however, there does not appear to be any consistent or reliable effective advice on how to fix this issue... and nothing I try seems to resolve the problem.

I'd be very grateful for any recommendations on a reliable repair for this issue.

But I'd also be grateful for suggestions as to how we might go about suggesting to the devs that this long-running bug is overdue a permanent fix.

Thanks in hope.

I'm crazy when I DO it. How do I fix?

I like the idea of horizontal tabs, but the line between the topics and the website is TOO DARN SMALL!

How do I go into to make it larger?

I know it's simple, but HOW?

And by the way . . . HAPPY THANKSGIVING!

Thanks!
