Diễn đàn hỗ trợ Firefox

I have had this problem for a while. I am not sure what to do so that I can fix this. Whenever I open a pdf or any application that can be opened in the browsers shows me two options for firefox browser. I attached a picture that will make it obvious what the problem is.

The problem is as follows:

Every time I load some multilagual web page (Aliexpress, prestashop.com fox example) Mozilla loads the page in different language. After I change the language and load a new page from the site, the language is changed again to a random one. Every time I click a button or link, the language is changed.

Cleared cache, and cookies and everithing multiple times. After 3-4 days it does the same thing. Tried fresh install - after a while starts to do the same thing. Installed Firefox Developer Edition - after 6 months starts to do the same thing. Installed Waterfox on different PC - same as Firefox Developer - after 6 months starts to do the same thing.

Does anyone have the same problem? Why is it happening? Is it only me?

After updating my openSUSE Firefox package from version 122 to 123 every frame inside each window started to have weird grey overlay of scrollable area. I failed to find any description of such a thing happening, let alone how to get rid of it. I tried removing build-in distro-default preferences and had complete audit of all my custom preferences in about:config but none changed that behavior. I even updated to 124b4 but this also haven't changed anything. Naturally, nuking entire profile is not an option, I might as well replace the whole browser. So, how do I get rid of this thing?

I'm running Firefox Dev edition and I cannot get it to load any pages except for Mozilla pages. I have tried all the fixes suggested there and it still refuses to connect. I'm at my wits end. Any hail mary optoins or do I have to reinstall and start again?

The new update just installed. What happened to my palm frond home page look!!?? I loved that. How can I get it back? OR at least, where do I go to change what this looks like and pick something else?? - Eileen

I have been seaching for the solution for the whole day, and i found the closest one. It Does remove tabs, windows buttoms, but the background bar still remains, and i dont need it this way. So thats the code i used to make it >>>>>

1. main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar .titlebar-spacer {

       border-inline-end: none;

}

1. main-window:not([extradragspace="true"]) #TabsToolbar > .toolbar-items {

 opacity: 0;
 pointer-events: none;

} /* This makes the bar shorter vertically but removes the 3 window buttons */

1. main-window #TabsToolbar {

 visibility: collapse !important;

} /* For full screen mode */

1. TabsToolbar[inFullscreen]{

 display: none !important; 

}

On the screenshot you can see what remains on tabs' bar place I need my browser to end just above the URL string, so there wont be empty space in the top of the monitor. Can you help me find solution for this problem, please?

Hey!

We have been trying to get to the bottom of this problem in my company, but we ruled out everything else than Firefox itself. Periodically Firefox experiences an APPCRASH event for multiple users. It used on a Windows Server 2019 that is used as a Terminal Server. When this APPCRASH occurs even though the profile of the user is there, Firefox creates a brand new profile for the user and all the passwords and form data is lost. Browsing history is lost too, but that is not a problem.

I've included some tracelog in the troubleshooting info field. Does anyone have any direction that I could go towards?

Thank you!

I'm having an issue where firefox is acting as if there's something blocking pages/content. I do not experience the issue on any other browser.

I first noticed it trying to log into one of my accounts. The login portal redirects the page to a success screen and then to the home page. With firefox after entering credentials it shows a blank page with a 500 error instead.More specifically I believe it has to do with an api for "duosecure" (checking for multi factor auth)

another example is trying to download chrome remote desktop - normally you click their download link and pauses the current page while it triggers a popup to chrome's page to download the extension. It does this in any other browser I try except firefox.

This is on a clean install of windows 10 and a clean install of firefox. I am on the latest version of firefox (tried 106 and updated to 107 via the beta options) I have: - cleared cookies and cache - restarted firefox - tried safe mode - tried with and without extensions/addons and have removed all - uninstalled firefox as well as deleted all appdata folders - tried unchecking hardware acceleration - setting dns to none and changing the dns server options - turned off any setting i could find regarding popups, blocking sites etc - manually turned off enhanced tracking - gone through windows firewall and security settings to turn off everything that i could find that was "on" - rebooted computer - rebooted router - used the "refresh" firefox to set it back to defaults - tried connecting to the internet via ethernet and wifi options - windows updates Note: logging into other things such as gmail or facebook are fine on firefox but they don't seem to trigger redirects to outside sites.

I kinda-frequently find myself in the situation that Firefox already downloaded an update, but some time passes before I bit the bullet of actually restarting it. So a new update has appeared - but I can't download it until I restart. So I will have to restart, reload session, download new update, restart again, reload session again.

So it would be great to be able to tell Firefox to forget about the already-downloaded update and just download the latest one. Can this be done?

(The reason why I delay restarting is because I have an unhealthy amount of tabs open, typically with many things in flight; so restarting makes me lose those things, plus there's always the possibility of some trouble while restoring all the tabs)

FWIW I'm in the Beta channel.

Starting with my bank's web site, my user name/password is being challenged. I can't bank. Elsewhere, where my desk top has always been recognized, I'm now forced to log in each time...and I receive an email that a new device has just logged into my account. All of this suspiciously coincides with a recent browser update. On my bank feedback it's showing as Firefox "125"...when all previous logins were recorded as Firefox "124". Help!

when I click the web address bar and the drop down opens up with commonly visited site a series buttons appear under it that I would love to delete from the face of the earth, as far as I can tell there doesn't appear to be any setting to turn them off and help topics are expectantly useless. For the love of god don't come and tell me you've added an idiot feature that I have no control over.

I tweaked my Firefox configs to get better font rendering because I hate how "skinny" they are by default on windows. The options changed are:

• gfx.font_rendering.cleartype_params.rendering_mode to 5
• gfx.font_rendering.cleartype_params.force_gdi_classic_for_families to ""
• gfx.font_rendering.cleartype_params.enhanced_contrast to 100
• gfx.font_rendering.cleartype_params.cleartype_level to 100
• gfx.font_rendering.cleartype_params.pixel_structure to 1
• gfx.webrender.quality.force-subpixel-aa-where-possible to true

After the update, the fonts are default again, and no matter how much I change the configs, it doesn't change anything.

Hi. I can't access my add-ons that I installed. When I click on the extensions icon it doesn't open that little menu like it does for other people, but it takes me to 'about:addons' in a new tab. I also want to pin my addons to my toolbar which is also not working. Please help me out

Hi,

I hope you are well.

I have set up 11 custom devices that max the min and max sizes of bootstrap grid system (xs-min-360w, xs-max-575, etc) to aid me with checking my website on various screen sizes. Is there anyway to export this list or better still to synch them with my Firefox account so I don't lose these settings?

I am using Firefox Developer Edition (101.0b6 (64-bit)) on Ubuntu 20.04.

Many thanks Kaz

MacOS FF dev edition 102 When I roll my mouse over a link, in pops up the URL in the bottom left (i.e. status bar as safari calls it) but there's no indication of if the link will show in the current tab or a new tab. in safari, the end of the URL states "in new tab" if that's the case.

Hi

This is on Ubuntu. I installed Firefox Developer edition to /opt/firefox and made a .desktop file I put in ~/.local/share/applications and this was working well. I added it to favourites so it appeared on the dock, and added some customizations.

But at some point Firefox started to create its own .desktop file at launch when it prompts to be default browser and you say yes, called stuff like "userapp-Firefox Developer Edition-N8YCQ1.desktop". These files fill up ~/.local/share/applications and break my existing file by making a second Firefox icon on the dock so I cannot click the first one. Also my own custom file had Desktop Actions so I could right-click the icon to open a new window or new private window, but the generated ones are barebones.

Every time I delete the "userapp" file, a new one is made the next time I open Firefox (which has now forgotten it is default browser) and the issue is back. Is there an option to disable this behaviour?

Thanks for your help

Hello! Short story: I recently discovered that adding a new GIF image to a page resets the animations of existing GIF images on the page with the same src.

Expected behavior: Adding a new GIF image to the page should not reset the animation of existing images with same src.

Actual result: Adding a new GIF image to the page resets the animation of all existing GIF images on the page with same src.

Code with example: https://codesandbox.io/s/heuristic-platform-jsguir Video demo: https://www.youtube.com/watch?v=k-ZMrrqq_KI

Simplified version of the code showing unexpected behavior: https://codesandbox.io/s/elastic-shtern-vwrcx1

Does anyone know why this is happening? Is this a bug?

When I try to play iplayer as of June 2022 it comes up with error 5000/5001. Other tv players are no longer playing either, Channel 4 for some time now. My laptop runs on Windows 8 and I have the latest version of firefox. In plug ins my codec is set on always activate as is Widevine CDM. I tried unchecking 'play DRM controlled content' in settings then checked it again and it has come up with Widevine CDM will be installed shortly, but nothing has happened.

many thanks, frances
