I have an mp4 (h264 AAC) video of 37MB which plays acceptably from my website in Safari, Chrome and Edge, but when played in Firefox (my default browser) the sound and picture synch is significantly seperated. When the video is compressed to 26MB it suffers some expected loss of sound quality but plays with near perfect lip synch. What is the issue with playback ?

The autostart of the page is attached. It is not possible to disable it. I have tried everything. I have uninstalled firefox and reinstalled it, but unfortunately the page still appears every time I start firefox. Before the update everything was fine, but after the last update it keeps showing me this instead of a blank page with favorites

As the title states, certain media elements within Firefox refuse to play with audio, but only with frustrating inconsistency. For example, any videos on Youtube are fine. Any videos on Reddit are fine. But many videos, most commonly on boorus and streaming sites I cannot name here, will not play. The volume on the video slider is all the way up, the Firefox application is not muted, the site is not muted, and the tab is not muted. The only thing that makes those videos play audio is if I left click on them to open them in another tab by themselves. While it solves the issue, it's still an extremely inconvenient way to go about my browsing. I know for a fact that this is a Firefox problem because those same videos on those same sites work perfectly fine within other browsers. Please, does anybody know of a solution to this issue?

Hallo zusammen,

ich habe 3 Bildschirme. Wenn ich auf Bildschirm A z.B. Youtube im Vollbirld laufen habe und auf Bildschirm B z.B was anderes im vollbild Laufen habe und ESC drücke wird das Vollbild auf beiden Bildschirmen geschlossen. Dies ist erst seit kurzem so und ist nicht beabsichtigt. Kennt jemand da eine Lösung? Das standardprozedere wie Cookies etc wurde schon genutzt und hat nix gebracht. Vielen Dank im Voraus.

I have used Firefox for years with no problems. The past month, however, I am encountering many problems with my often used web sites. What is going on? I make a purchase and cannot proceed. I have not added any new blockers or anything.

My wsj.com suscription loads the main screen, then for an individual article briefly shows some of the content before dissapearing and reporting "Application error: a client-side exception has occurred (see the browser console for more information)."

Using latest Firefox in updated Windows 10.

No similar problems with other sites.

The first image speaks for itself. When I want to change the way this setting is set in a Facebook group, when Firefox is full screen, the associated dialog is so placed and/or sized on the screen that it is partially truncated on the left by the left side of the display. I just checked in MS Edge and it displays normally there with full screen display. It displays normally in Firefox when I Restore Down. So this one at least does seem to be specific to Firefox.

I have a second full screen display issue that may be related, but this one isn't just Firefox; Ms Edge also shows it, and other applications also behave similarly: the right hand scroll bar disappears in full screen (as does the applicaion menu control)! I had some trouble taking a pair of images to illustrate this, using Snipping Tool. The second image, when Firefox is set to restore Down, shows the scroll bar and application menu control, which is what I see. The third image was more tricky to take because the first time I tried, the screen capture included a scroll bar and application menu control even though they were not visible on screen. I had to redo it and be very careful not to let the right hand side of the selection drift off the right hand side of the display.

It seems like the full screen display is just a little "larger" than the physical display. I have tried one or two other screen resolution settings and that has not helped. My best guess is that it's a monitor settings problem, but I've also fiddled with the monitor settings, again with no success. And even if a monitor setting explains the pervasive right hand side issue, it doesn't explain the Facebook dialogue issue, which does appear to be Firefox-specific.

So my current workaround is just not to have anything full screen :(

Is it possible to click individual segments of an URL in the address bar to navigate there directly (without manually selecting and deleting the tail)? It's a convenient way to reach upper layers of a website.

For example Vivaldi implements it via Ctrl+<Mouseover/click> (see attached screen capture)

Is there an option or addon to enable this? Thanks in advance

i restarted firefox, and on it's new tab when re-opening it offered the "review checker", so i clicked the "try on amazon" I don't get the icon in my search bar. is it an add-on/extension that i can just search for in the google store even though it's in beta?

When on google.com, clicking the search engine gives the error "Uncaught Storage mechanism: Quota exceeded", of which this does not occur on other browsers.

Why is there no price tag icon for Review Checker in the search bar for Amazon and Walmart? (I am signed in to Mozilla, and I tried turning off all my adblockers and Privacy Badger.)

Thank you for your suggestions!
