Youtube does not work. It shows somekind of default page that is essentially blank. It does say: "Try searching to get started" and "Start watching videos to help us build a feed of videos you'll love."

But it will not respond when I attempt to search anything.

I believe I had all this synced in Firefox Settings before I made the upgrade. Like all you fellow former users of Windows 10, I had to upgrade to Windows 11; and did so two days ago. Now, I found that I do not have under History any of the former sites I not only visited but also had tabs open. What can I do, if anything, to recover them? Under the Add-ons Manager, if this helps, I already had the app Tab Session Manager, but don't know how to use it. Thanks to all in advance who may have made this same upgrade. Many out there are still on Windows 10.

What should happen is that the main image should change on mouse hover over one of the images from the column on the left. Also it should be possible to use the left or right navigation arrows on the main image to cycle through the images. Neither of these actions is possible. It works fine on Edge.

My Firefox keeps crashing several times daily.

Here are reports of the latest:

Since updating to Firefox 144, access to bookmarks on my PC running Windows 11 25H2 has been restricted: - Sometimes no bookmarks are displayed at all. Instead, a message appears stating that access to bookmarks is restricted, for example, by a virus scanner. The problem persists even after restarting the computer. - Sometimes the bookmarks are displayed again, but I can neither delete bookmarks nor create new ones.

Disabling the virus scanner (Avira) and other security programs does not solve the problem either. The problem also occurs in Windows Safe Mode.

How can I use the bookmarks normally again?

I bought a new PC 64 bit with Win 11. Insalled the latest Firefox. Loged in to my account, but I can get sync to catch my bookmark the old PC. Eksported the bookmark in HTML from my old PC, but the new PC tells me this is not a HTML file? I shut all the extensions down, bult still no sync?

I have no problems transfer the bookmarks to Edge on my new PC, but I can still not import the bookmarks from Edge to Firefox. I hav read som articles from Morzillas site, byt I can solve this problem. Any good advise?

Best regards Lars Beneke

Guten Tag,

Im Firefox Developer habe ich seit ca. einer Woche das Problem, das die Lesezeichen nicht mhr funktionieren. Kann weder etwas anzeigen lassen, hinzufügen noch importieren.

Das zweite Problem habe ich heute 07.11.2025 festgestellt, habe einen neuen Tap geöffnet und es werde auf einmal die gespeicherten Webseiten nicht mehr angezeigt.

Was kann ich tun? Developer habe ich gelöscht und wider installiert, auch resettet, doch es geht nicht. Auf der zweiten Firefox Brwoser habe ich zwar die Lesezeichen, doch kann keine Webseite mehr hinzufügen. Auch bei öffnen eines neuen Taps, sind die gespeicherten Webseiten verschwunden.

While taking screenshot of entire page or section within the page, taken screenshot resolution is of very low quality. As a result when shared the screenshot with someone using copy paste function or download and share option, in both methods screenshot image quality is very low making it very difficult to read data/text from the same. Text from the screenshot is barely in readable format. Even zooming the image distorts image totally. I want a way to increase screenshot resolution or improve its image quality so we can read easily without zoom or zooming the image file.

This one is puzzling to me: On a website with login, whenever I click on an link to a pdf, a new tab opens (my normal setting) and immediately crashes (not my normal setting ;)). However, everything is fine elsewhere on the web, even on the same site in the sections without login. Here are some observations that may or may not be connected to this:

• If I right-click and open in new tab/window/download, everything is fine
• When I return to the tab where I clicked the link, the page reloads - independent of whether I did anything in the crashed tab
• the site-admins were not able to reproduce the problem, also it seems fine for other users
• the problem persists in troubleshooting mode, also manually disabeling extension did nothing, emptying cache etc. also nothing.

It is not like this is making me switch browsers (although no crashes in edge), but it bothers me to have no idea why this is happening. :) Maybe someone here feels the same? Thank you for reading either way!

Hi, I’m facing an issue where some websites do not load properly even after clearing the cache and cookies. Sometimes images don’t show or pages freeze. Is there a method to force fresh loading or bypass the cache?

Thank you.

The offline package download speed is too slow and sometimes fails. I hope it can be provided separately, like interface language packs, just as Debian has separate interface language packs.

Windows 10, latest version.

I hit a shortcut, I think, and heard the trackpad, then one of the three open tabs was isolated from the rest in a separate, almost chromeless window.

It's not in the taskbar pop-ups but instead has its own icon. In this 'chromeless' window there is no option to add a tab or window, there is no area to move it (I have to carefully use emtpy space in between buttons to move it). The top just fell off, that's basically it.

I have never seen this and have been using Firefox from the start way back when. I didn't install anything; this just happened as I was reading something and accidentally touched a key. Nothing changed, no settings were adjusted, nothing.

This option is not in the tabs menu or anywhere. I must say I kinda like it for this one 'tab' (which is a solo chromeless window) but I do need the menu and so on for productivity.

One of the screenshots shows this 'window', the other shows that 'window' is not part of the regular pop-up tabs in the taskbar but rather has its own icon, as if it were an app, in that taskbar.

What in the world is this? Can someone help?

Mozilla sidebar has been replaced by "Choose an AI chatbot to use in the Firefox sidebar." How do I undo this and return to Mozilla standard Firefox sidebar. Not at all what I want to do. Help

I need to be able to place bookmarks in bookmark tool bar. this is what it say: For quick access, place your bookmarks here on the bookmarks toolbar. I tried with Yohoo news it wouldn't stay.
