Firefox Tekoha Aty

When i watch netflix,youtube and etc i cant go fully full screen. i see my desktop wallpaper a small bit on the side and top of my monitor. i only had problems with firefox this way. before i usually could just go out and in to full screen and it would fix but now i cant and its really iritating

I have my desktop extended across two displays. If I disable Hardware Acceleration in Firefox, entering fullscreen causes the window to be slightly offset down and right, leaving a thin band on the top and left sides of the screen where the desktop background and taskbar are visible behind the Firefox window.

From testing I have determined that this issue does not occur if I only have one monitor enabled or the monitors are mirroring the same display. I have also determined that the issue only occurs when Hardware Acceleration is disabled.

Hi

I need to block some sites through the OS Hosts file, Other browsers ( Edge, Chrome, .. ) are honoring the HOSTS file rules but Firefox bypassing them !! , I disabled the DNSOverHTTPS and all other available suggestion and options but still not honoring the hosts file !

as you can see in the attached file, the Firefox DNS Section is now blank ! but still doesn't follow the OS host file

I even made a custom policy file but still doesn't work, these are the things I disabled but still not working :

{

 "policies": {
   "DNSOverHTTPS": {
     "Enabled": false,
     "Locked": true
   },
   "Preferences": {
     "network.trr.mode": {
       "Value": 5,
       "Status": "locked"
     },
     "network.dns.native_https_query": {
       "Value": false,
       "Status": "locked"
     },
     "network.trr.uri": {
       "Value": "",
       "Status": "locked"
     },
     "network.trr.bootstrapAddress": {
       "Value": "",
       "Status": "locked"
     },
     "network.trr.exclude-etc-hosts": {
       "Value": true,
       "Status": "locked"
     },
     "network.dnsCacheEntries": {
       "Value": 0,
       "Status": "locked"
     },
     "network.dns.disableIPv6": {
       "Value": true,
       "Status": "locked"
     },
     "browser.fixup.dns_first_for_single_words": {
       "Value": true,
       "Status": "locked"
     },
     "keyword.enabled": {
       "Value": false,
       "Status": "locked"
     }
   }
 }

}

I use Arcgis quite a bit for property info and for the last several months, it either won't fully load or has constant freezes when doing anything. It also freezes other windows I have open and most the time when I shut down those windows and start FireFox again, my home screen (Start Page) won't load? I have to dump history/cookies and sometimes flush dns. I contacted ArcGis and they say it works fine on their end. So I suspect FireFox is the issue.

I downloaded the Opera browser last night and it has no problems with this site. I won't use chrome or edge.

Any help figuring out what's going on? I have changed no settings, no vpn, no private browsing either. It seems with each FireFox update, my issues get worse?

Win 10 on desktop. FF version 145.0.1 the site in question https://experience.arcgis.com/experience/ba70b3d86f5e4bbeb7582591f3dde16a/

Some websites won't load at all while other are very slow to load but some will load just fine, example Crunchyroll (screenshot attached) won't load at all its just spinning loading icon and a white page but if I try it in a different browser it works just fine, but with Youtube it will load but is choppy and low quality videos and same thing as before I load it in a different browser and no problems. I have tried every possible solution I can find from clearing cookies and cache to refreshing Firefox even scanned for malware and virus nothing has worked please help me figure out what is happening and why it's only with Firefox that I am having this problem and its not hardware can play online just fine and download games from steam perfectly fine.

I got a new computer. The old computer is inaccessible. When I downloaded Firefox on the new computer, I could not remember my password and had to reset it. Now all of my synced data is lost. Is there ANY way I can get this information back? I absolutely need the bookmarks on my account to be able to pay bills, and i had no idea changing my password would cause the synced to be lost.

On Facebook I get posts from DoubleDown casino that have internal links to acquire free credits/points. When I click on the link, DoubleDown begins to open but goes "grey" and shows a rotating/pulsating circle but never opens. Any idea why? What do I need to do to get the links to open. No problem with Google.

Hello.

English is not my native language, so I watch all TV series and cartoons in English with subtitles in my native language. Everything was fine until, at some point, one of the most accessible players that provided subtitles stopped displaying them. I thought that the player had broken or that some technical work was being done. But after a week, nothing had changed.

Then I downloaded Chrome, and the subtitles display perfectly in it.

It is in Firefox, specifically this player, that subtitles are not displayed. Other players display subtitles, but they are either unstable or constantly crash. Therefore, they are inconvenient to use and spoil my user experience.

In general, if you have any tips, I would be grateful.
