Firefox 技術支援討論區

Hi thanks for clicking.

I'm on Linux, Zorin OS, which is Ubuntu based if I'm not mistaken, very new to Linux.

Anyway, I've made a userChrome.css and done some changes I like to Firefox. It has been working fine until I tried to change the tab bar's overflow shadows when there are more tabs than there is space in the bar.

The rest of the css edits I've made in userChrome.css works fine but this overflow shadow reference Firefox just doesn't grab. I can live edit with the Toolbox and then it works fine, but when opening Firefox as default this css definition is as if gone.

Image 1: after live edit with Toolbox Image 2: before live edit with Toolbox Image 3: my userChrome.css

What can I do to fix this?

Thanks / p

Some months ago, Firefox stopped displaying the blue progress bar that would normally show once you clicked on the download icon. You still see the usual file info but now the progress bar of the download is gray instead of blue and is extremely hard to see. You have to look closely but in the first screenshot you can see where the shade of gray of the progress bar changes, just under the "6" of the "x86" part of the file name. But if you click on the "show all downloads" link, then the blue progress bar will show as usual for any in-progress downloads in the Library window, as shown in the second screenshot.

It isn't a huge issue but is still annoying when you just want to quickly see the progress of downloads in Firefox. I haven't changed any of the colors in Firefox or in Windows for that matter, I'm currently running Windows 10. All other dialog boxes, windows, etc. all display normally on my system. Just curious if anyone else is having this problem and hopefully a future update can take care of it.

Thanks very much!

I am using Firefox v125.0.2. When I open a PDF in Firefox it takes a lot of time to load. But, when the same PDF opened in the Edge browser it loads normally and scrolling through PDF pages renders fast. I have shared the screenshot of a single-page pdf loading taking quite a long time.

Could someone please help me with this.

This is almost surely a "security" or "privacy" design, but it's an error. In Firefox - only (this works fine in Chrome) - if I open the LastPass Firefox Extension, find a Site, and Copy the password, then go directly to an open AnyDesk remote access connection, and Paste (or, lightning bolt menu, Insert from Clipboard), what gets pasted is a single wrong character, NOT the password that IS in the clipboard. (If I paste instead into e.g. a local Notepad window, the actual password gets pasted). I asked AnyDesk support about this, and they confirmed that it's something that Firefox is doing. It shouldn't. Copy is copy. Paste is paste. Why would Firefox do something so that copied text (which just happens to be a password from a password vault extension) pastes wrong when the destination just happens to be a remote desktop client (AnyDesk) to send the password through to complete a login at the remote end? Anyway, how to turn off this wrong behaviour? thank you. (Windows 11 Pro, 64-bit, 23H2, Firefox current - 125.something today, but this has been going on for some weeks at least, AnyDesk version 8 current)

When reloading a page, or navigating to a new page, the default Stop icon momentarily appears over my own Reload icon, and the default Reload icon also appears over my Stop icon.

Please see attached image and animation.

Any idea if this is a minor bug?

Below is my code to split the Reload button into Reload & Stop buttons, then to add text to the navigation buttons, and finally to add icons to the navigation buttons.

This anomaly happens whether or not I split the Reload & Stop buttons. With just a single Reload button, I'm also seeing the default Reload icon appear over my own.

Thank you.

Firefox stopped working with my VPN on when I updated my OS to Sonoma, yesterday. I use PIA for my VPN.

I have done the following, so far, restarting my system several times between trying these things:

Checked that internet connection and modem are fine. All pages load in Safari, with VPN running, but I prefer Firefox.

Checked the Network settings for my Mac. Ensured that No Proxy was selected.

Cleared my Firefox cookies, cache and history.

Tried running in troubleshooting mode, turning off all extensions.

Tried turning off Advanced Tracking Protection, which I usually run on Custom.

Refreshed Firefox.

Finally, I turned off my VPN and, viola, all sites work. Turned it back on, and can’t navigate, again. For instance, I tried to open YouTube, and got a blank screen. Turned off VPN, and got to main YouTube page. Turned the VPN on and tried to log in…nope. Turned it off and logged in. Turned it back on and tried to open a video….nope. Turned it off and opened the video…etc., etc..

I very much wish to continue using both Firefox and my VPN. Can you suggest a course of action? Thank you for any advice you can give!!

Please someone help me with this. My primary email has been breeched and because I was honest with the service --instead of just saying I need help resetting my password. Thay are asking me to send them a copy of my drivers' license and a photo "selfie" of myself to recover my account.

This is where I draw the line -- all invasions of privacy we have learned to live with but not this -- I could give them the transaction ID from my last Payment from Paypal period -- but that was not good enough. If I was being deceitfull I could easily provide the crdentials they ask for and it could all be fake; so I told them to get lost as I was paying for the Premium service anyway. I can contintue to use that as my ID but sonner or later someone is going to want to send me a code there and I can't retrieve it. Tonight they did not ask so I was able to get in here.

Everybody has a place to change your password but few have a place to change your sign-in ID. If I can get back into Firefox with a new ID and set 2 step validation I shouls be okay as faras the average user gors. The other option that I know of is to stary a new Firefox account. I alread have a lot of people and business's that I have to get my new email to.

Thanks To Anyone with any ideas.

Sincerely Paul

What strategies or technologies has the Firefox platform implemented to ensure efficient memory management and minimize resource consumption, particularly in handling large-scale web applications and multimedia content?

I have used Firefox for many, many years and have always loved it. Recently, it stopped loading some websites. I have read and tried everything I have read and still can't fix the problem. I have to switch to Edge to load the sites. I am tearing my hair out trying to get this fixed, but I will have to use other browsers if this doesn't get cleared up. Some sites load and most don't, but there is no rhyme nor reason to what it loads and what it doesn't. I do not have a great deal of tech know-how and cannot seem to fix this according to my research. I get no "error" messages except that the page can't load. Please help. I would hate to have to learn another browser.

EVERYTHING especially

 * The time to receive the first HTTP response when connecting
 * the time to call up the various css elements that make up the screen
 * the time to call up the img elements on the screen
is too slow.

tooooooooo slow. I waited 36.6s until http response for every new URL open! Of course, I am using a lot of Firefox extensions, but there were no serious problems outside of YouTube, and the same problem occurred after removing the extension, and i also confirmed that the problem caused by web extensions on waterfall(on firefox profiler) was minor.

I can't even guess the cause of the problem, so unfortunately there seems to be no additional information that I can give you. I'll keep following up as long as I can. I will attach some pictures that might help you solve the problem. and you can also approach to my full-recorded firefox profiler data

No longer able to copy or paste text on Firefox with Windows 10. Copy and Paste are greyed out in the right click menu after selecting text. Using CTRL-C, V or P does nothing at all. Still works fine in other browsers. What has Firefox broken again this time?

Greetings, Mozilla Community I'm reaching out to you to get assistance with an issue I'm having with Mozilla Firefox when trying to access the following website: https://strandsgamenyt.com/ I'm not sure if there's a bug in the website, if it's incompatible with some browsers, or if the browser is blocking anything, but it won't load.

Does anyone else have experience with this issue or suggestions for a solution? I've tried clearing my browser's cache and deleting extensions, but the problem persists.

I would appreciate any guidance or thoughts on making the website easier to use. I appreciate your help in advance.

I see my original question is now archived at https://support.mozilla.org/en-US/questions/1380948#question-reply I never closed it because I didn't know if my last process could really fix the issue. It didn't, not always. Over the years, there have been times when the issue would still pop up, but not as often as before (2022 and earlier).

I have a feeling that during an issue, FF is having difficulty setting up shop after starting up. Consequently, it is spending more time before it could become prepared to connect to the Net. I've come up with another "solution," which is deleting (or moving out) xulstore.json in the profile folder after exiting or before starting FF. You can create a batch command or script to execute the process.

So far, FF is connecting immediately after startup.

Device: Surface Pro X SQ2 OS: Windows 11 Home for ARM (Up-to-date at time of writing) Firefox Version: 125.0.3 (AArch64 up-to-date at time of writing)

I am having an issue with Firefox and video playback, specifically on YouTube. When I play a video in default view mode, the playback is super choppy / low frame rate. When I change to theatre view or full screen, playback works perfectly.

I've tried incognito windows and troubleshooting mode with no improvement.

Microsoft Edge works fine.

Not sure where to go from here.

Hello, Mozilla Community I'm contacting you to ask for help with a problem I'm having with Mozilla Firefox when attempting to visit the website https://canuckletoday.ca. The website won't load, and I'm not sure if that's because of a technical glitch, incompatibility with certain browsers, or anything the browser may be obstructing.

Has anyone else had this problem or has advice on how to fix it? I've tried removing extensions and cleaning the cache on my browser, but the issue still exists.

Any advice or tips on how to navigate the website more easily would be much valued. I'm grateful for your support in advance.

When I try to use needed tools on websites, Mozilla is blocking the page from opening. USPS will not allow me to track a package. When I enter the tracking number, the page just sits on white and the search just spins

Hi, I've been trying to get the Multi-Account Containers Add On to work on my computer for quite some time. Would be very handy for me. When I add the Add On to my browser the icon on the top right of the screen just won't show up. Don't know what I've been doing wrong...? How can I access the container settings someway else? I've made changes to my FF settings in regards to privacy via the recommendation from Sun Knudsen but don't really see an issue here. Thanks in advance!

macOS 10.15.7, Firefox 125.0.3

Unlike Safari, Firefox doesn't autofill passwords or 2-factor codes. Please implement these features or tell me how to get them to work. MacOS 14.4.1 Thank you, Steve
