Firefox 技術支援討論區

Firefox recently stopped working. I tried uninstall/reinstall, removal (name change) of AppData\local\Mozilla, local low and remote folders before installing. All the same result that when I click Firefox, the cursor will start to flicker, the program shows in the task manager but never starts. When the AppData folders were removed, new ones were not created.

The only to changes were that I was given temporary admin privilages on Avecto Privilage Guard and I installed Visual Studio 2022 - removed 2019 as well.

Since the latest update in Firefox, I am forced to compose new messages or reply or forward in a new window in Firefox, which I access with a pop-up window that appears on the page where I previously would simply respond. This is not happening in Edge and only started with the Mozilla 99 update.

When downloading files, FF opens a window to file manager. The window enables user to choose the download directory. But the window extends past the right side of the monitor, thus the "save" button is not displayed. Thus, files cannot be saved.

I started using Linux Mint a few months ago, and since then have had issues with opening Firefox on startup. The attached image shows roughly what Firefox does the first time I try to open it after starting my computer. I usually have to close and re-open it 5-10 times before it will launch properly. At this point, I usually manually recover my previous session. Does anybody know of a potential fix to this problem? I have tried updating Firefox and have also tried uninstalling and reinstalling.

Hi,

I've upgraded to Firefox 99 (on Linux) and a website that works fine in Firefox 88 and Chromium 101 has stopped working for me - I can't get the log in form to show up.

This is in a standard window (as opposed to private) with all add ons disabled, Enhanced Tracking Protection switched off for the site and protection settings set to 'Custom' with everything switched off (and same with protection settings set to 'Standard').

The website is:

https://www.riverford.co.uk/

and then click on person icon in the top right corner.

I'm having similar problems with other websites, eg

https://www.ebi.ac.uk/interpro/

in a private window (but weirdly works fine in a standard window) - click on 'Example protein sequence' to fill in a sample sequence and then press 'Search'. In a standard window this works but in a private window the 'Search' button doesn't work. (If the search button does work for you, please delete the job afterwards by clicking on the rubbish bin/trashcan icon so as not waste their resources.)

I am hitting a rare issue where some requests don't seem to complete (uploading files).

Unsure if the issue is at network level or in the JS code of the website I am using.

What is the best way to troubleshoot those requests that don't seem to complete?

In the Web Developer tools there's nothing under the Timing section.

Thanks

• When I try to print a webpage using Firefox, the page enlarges 4x and therefore I only get 1/4 of the webpage on an 8.5 x 11 sheet. If I change my browser to Chrome or IE, it prints correctly. If I scroll to the bottom of the Firefox Print Dialog window and select "Print using system dialog" it also works correctly.
• I have the zoom set to 100 and the Print Dialog paper size set to Letter, It is set to print to page width, I tried it with Scale 100 but it didn't help. I also went to about: config and checked that the paper size and scaling were set to 1.
• The the picture of the Print Preview looks exactly like should be when printed, but when it is sent to the Lexmark S505 printer the size is too large.

Since I print 50-100 individual webpages a week, I cannot use Firefox if this can't be corrected.

Thanks, Randall Win7 Pro

I downloaded Firefox a while ago and it would work and just a few hours ago I had completely restored my pc to see if it improves issues I had and speed, but the same issues I was having with Firefox are still happening. When first downloaded it runs for maybe 2 seconds then crashes and if you try to re open it, you either cant or see it pop up in the task bar only to go away the next second like a flicker. I've deleted and redownloaded it already and I cant find the crash report on my pc even from the Win + R so I was wondering if anybody ever had an issue like this and how they fixed it.

I have since a few weeks errorcodes showing up at my screen whenever i want to visit a website where videocontent is to see( like if you want to visit reddit and watch a video or something like that).I´ve didn´t do or didn´t visit anything special when it came up, it just came and now its there.I´ve also tried different things from the help articles that could solve the problem, didn´t do anything. It says in its message "secure connection failed". The problem is also on every browser, not only on firefox

I am able to install Firefox, but as soon as I try to open it, after a second a window pops up for probably about 1 frame, and is barely visible. I have tried all of the things I could, but am not able to fix this.

I began having trouble w/Firefox browser yesterday evening. I submitted details several times. Completed lengthy Win 10 update. Today, Firefox icon in Task Bar is requiring Google log-in? Have no idea why or how to fix.

I'm unable to check out when I'm signed into my accounts at target & clinique.com.Target say my checkout page is slowing down firefox-click stop -I click stop&I cannot check out.

So even on a unprotected machine, some webpages VERY slow to load but not all. My internet provider, Virginmedia, is also my email provider and sometimes this email homepage times out. Had the same problem with win 10 and did think, wrongly, that installing win 11 would cure this. It did not. Any ideas on this. A good friend is a computer tech so you can get technical. In `task manger` anti virus etc has been stopped.

FF VER 99.0 64 BIT BASE UNIT

This problem appears on MacOS 10.13.3 but NOT Linux Mint 19.3 (Tricia).

Repeat-by:

1. Start here:

       https://www.cnn.com/

That page should load cleanly.

2. Now click on "Live Updates", which is the top entry in the middle column of that page, and as of 3 April 2022 11:20 AM EDT takes you to:

       https://www.cnn.com/europe/live-news/ukraine-russia-putin-news-04-3-22/index.html

On MacOS, that page loads and is momentarily visible; then the page/tab it's loaded in goes blank. On Linux, that page loads as expected and remains visible.

Notes:

The problem did not happen with Firefox 88.0.1/MacOS.

The problem does not happen with Firefox 98.0.2/Linux, i.e., it appears to be specific to MacOS.

The problem remains whether extensions are enable or disabled (one a time or all at once).

The problem remains after the cache has been flushed and pages have been reloaded.

The problem remains after Firefox has been (completely) shut down and (cleanly) restarted.

The problem does not happen with Chrome/Chromium on either MacOS or Linux.

The problem also happens on *some* other pages on CNN's site (but not all) and on *some* (but not all) pages of other sites but there doesn't seem to be a pattern that explains which URLs exhibit it and which don't. This suggests that it's not privacy settings or extensions or anything like that, because there's no reason for those to vary from page to page within any one site.

If I'm VERY fast on hitting the "X" that stops a page loading/rendering while in progress, and I get the timing just right, I can catch it before the page/tab goes blank. So it appears that Firefox is in fact fetching all the content and can render it, but then for some reason is blanking the page/tab once that's done.

The attached screenshot shows what the problematic page (from step 2 above) looks like on Linux. On MacOS it's blank, so I didn't include a screenshot of that.

Hi, I'm having a problem with my Firefox where it doesn't let me change some of my settings. This is my home PC and I've already tried running Firefox as admin and the settings are still locked. I have reset it many times and haven't installed any extensions. I can't find anything online about this.

Since this morning Firefox keeps crashing on my PC, not only tabs, but the whole browser. I've sent countless reports so far. There is no error message. Is there a problem with Firefox today, or there may be another issue? Please help, thanks.

My firefox browser is completely unable to load any tabs. The search bar works but screen remains blank after pressing enter, I have tried uninstalling and reinstalling with no change. Thank you any help

Hi,

i am having a rather weird and persistent issue. When I try to open a specific website, namely www.westend61.de, this Firefox tab crashes, as seen in the provided screenshot. With a normal website this wouldn't bother me so much, but this page is the main page of the company I work for, and therefore I and potential customers must be able to reach it. That being said, this does not necessarily have to be a Firefox problem, the issue could also be on the server side. But the website works on other computers, other operating systems and other browsers. As far as I know, the website works fine, this computer using this browser being the only exception. I worked my way through the Firefox support page:

- checked for newer firefox version - checked for newer compatible MacOS version - checked for newer graphics driver - disabled all firewall, anti virus software - started firefox in Safe Mode - reinstalled firefox & deleted all profile data - disabled hardware acceleration - set webgl.disabled to true - again safe mode

The tab crashes every time. This computer is an old End 2015 iMac running Monterey and the newest Firefox. - More information can be found in the troubleshooting information and the crash report: https://crash-stats.mozilla.org/report/index/bb11e42d-9fc9-4061-b89c-4c6400220503

Thank you very much.

The latest version of Firefox was just installed and I am now having constant crashing problems the performance is significantly worse than the previous session. How do I go back to the previous version. Note to Firefox please do not use us a your Beta testers.

I have seen this in some past versions of FF It usually goes away after a few upgrades

Instead of whatever it's supposed to display, you can see that it shows some random characters.

Annoying. I dont even remember what it's actually supposed to show
