Diễn đàn hỗ trợ Firefox

I've been having an issue of, whenever I tab into Firefox from a different application on my computer, the alt menu opens. Firefox seems to be interpreting me opening the program as pressing the alt key, because even when I have the menu bar set to always be open, the input immediately goes to the "File" dropdown option of the menu, just as it would if I pressed the alt key. However, I tried to troubleshoot this by 1. opening a program that tracks keyboard inputs and that didn't show such a thing happening, and 2. I checked if this issue was happening with other applications that have switch the input to the upper menu bar when the alt key is pressed, and that was not the case. This is making it a lot harder to use Firefox, as using a keyboard shortcut to open a new window (ctrl+shift+p, or ctrl+i) while in a normal Firefox tab, it will not automatically open to the new window (as it is set to do automatically), it will also not let me open the new window -- either by alt-tabbing or by clicking the new window on the windows taskbar -- and instead reopens the alt menu and sets the input to that menu, locking me to the original Firefox page unless I tab into a completely different application and then into the new window. This issue also makes me unable to input key commands or text into my active tab immediately when I reopen it, instead forcing me to close the alt menu first either or clicking somewhere on the page. And since I don't keep the alt menu visible at all times, this forces the screen to shift up and down jarringly when I'm simply trying to use the computer.

I'm using Firefox on a Windows 11 computer. I've tried refreshing Firefox and have tried my absolute best to find articles related to this issue but to no luck. Thanks for any help or advice!

After the latest auto update all of my history, tabs/windows, and bookmarks were deleted and I can't recover them. I have tried importing bookmarks and it does not allow me to upload an old data file and I can't restore my previous session. I tried checking both profiles but neither had my information saved and now when I open the about:profiles says "Another copy of Firefox has made changes to profiles. You must restart Firefox before making more changes."

I'm scared to try anything else because I don't want to mess anything up further but I really need my tabs and history back.

I restarted my computer and then reopened firefox and it had updated and I noticed my bookmarks were gone but my windows/tabs were open, so I tried to choose a file on the bookmark backup and nothing was happening so I restarted and after that all my history and tabs were gone and I couldn't restore them.

My settings: Downloads: save files to: [custom default folder, unimportant] Always ask you where to save files: ENABLED

Applications: PDFs: Open In Firefox (because when the browser has such a nice built-in pdf viewer of course I would like to use it)

Expected behavior: Browser will open the dialog box for where to save the pdf, save the pdf, then open it in the in-browser viewer from the location it just saved to. Or possibly: save the file to TEMP and then open it in browser, I can see the argument for that behavior, though it wouldn't be my first instinct.

Actual behavior: Browser blindly saves the pdf to the specified default folder, then opens it in the in-browser viewer.

What is the actual point of the ALWAYS ask checkbox here? From what I can find extant on the forums the devs somehow don't seem to consider this a bug, so does anyone know how to wrangle the config page and/or some kind of extension into producing the actual logical behavior for these settings?

Less a question, more a statement. On most updates (every? I don't know) I loose my dictionaries and the spellchecking does no longer work.

Also, after an update the browser just ... dies. I mean it still works but it is if I would have no internet. Usually some tabs die before the others.

So yeah, this little rant hopefully opens a ticket and you guys can check if others have the same problem.

Also if you are wondering why nobody is upgrading. Yeah, that is the reason. I try to delay it as much as possible.

While you can disable event listeners in developer tools, the site may still load them later during use. Is there a way to prevent them from loading or at least automatically disable them as soon as they load without using developer tools?

This started after the recent update. Any time i open more than 1 firefox window or try to move my window to a different monitor, the Menu Bar pops up and left click will be stuck only making the bar appear/disappear. I just have to close the second window because it becomes immediately unusable. I have the ui setting set to false but it still freezes new windows and doest let me click or type on anything. I've uninstalled and reinstalled, ran troubleshoot mode, got rid of extensions, reset my computer. I'm at a loss. Any help would be great

I cannot access sites such as my live.com email and Facebook because it keeps saying wrong password, and even when I try changing the password in the Password section it will still not work.

I have just updated to 145.0.1 and i have some passwords saved as exceptions, so I do not have to log in every time... They are saved still but it is still making me sign in, does auto fills but i have to sign in and go through security checks.. They are saved in exceptions... Also tabs are not opening in new window still , since the last 2 Firefox updates. Are working as they used too in other browser.. I would love some help please. A running Win 11 updated from 10

Not sure I picked the right subject. Bookmarks is what I want to talk about. My bookmark files are all gone!! Am I going to get them back or what? What can I do to get them back? I really need them!

Since some of the updates, now the tabs aren't scaling vertically, and it is very annoying for me, because I used to just click the highest point of the tab to access it, but not I just hit nothing.

Is there a way to make it full height as for smaller screens?

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/

At least once a day since Version 145 dropped Firefox has told me I need to restart to update. When I do, it shows a pop up telling my I am opening an older version of Firefox and need to create a new profile to avoid corrupting my data. Daily, sometimes twice a day I have to go in and switch profiles back to the profile that has all of my book marks. Every computer in our office has this issue now. One of them deleted a profile without prompting, and it is not even in the appdata folder with "deleteme" in front of it. It is just gone. The last update had tabs crash daily. Is there any hope of stopping the second broken update in a row from wasting my time fixing it every day?

Hi Mozilla team! I have a problem which started happening recently, or at least I didn't realize it before. I went through all the articles, tried adjusting density in Customize Toolbar, went through all the settings with systematic approach with ChatGPT, some things in about:config and even tried adding userChrome.css in profile folder but nothing helped.

The problem is that I have PC with dual screen setup, one is 1440p, 125% zoom in windows settings (main) and 1080p, 100% zoom in Windows settings (secondary). When I change both screens to same zoom, everything is fine, but when it's set up like this, on secondary monitor (1080p one) tabs in open browser don't reach top of the screen, in fullscreen mode, that is, I need to move mouse downwards if I want to middle click open new tab or close old one or even simply move between tabs. It's like, it doesn't reach top of the screen for few pixels - it has a ghost gap.

I don't have this problem in any other browser, tried Chrome, Edge... I would like to continue using Mozilla, but this is bothering me. Could you please consider fixing it in some of future releases?

Thank you in advance!
