Firefox 技術支援討論區

I always had one version of Firefox installed. I regularly update the software via Help >> About Still, after every update, I am getting multiple versions of Firefox listed at [Settings/Installed Apps] and [Control Panel/Uninstall or remove apps] on my Win11 23H2 22631.3593 (screenshot attached).

In order to get rid of outdated items from the list, I need to reinstall Firefox completely, but the same thing is happening with every update of Firefox.

Is there a way to resolve this and why is this happening?

Hello! I've been noticing for several versions of Firefox that the response times reported in the “Network” tab of the developer console are wrong. In Chrome it shows the true value, which are a few ms, while in Firefox they show that it takes several seconds!!!! I attach the images of the problem.

Is it a bug, or a configuration problem itself? Thanks in advance

I am unable to sign into the 7plus.com.au website.

I have tried creating a new profile in Firefox (firefox.exe -p) but I have the same issues when using the new profile.

When I go to the website, the 'sign in' button does not respond, nor does the 'Register' button. When I click on the 'Connect your TV' button and enter my credentials, I receive an error message:

Failed to sign in. Please try again later (error -1)

I do not have these issues if I use another browser, so this leads me to believe that Firefox may be the issue.

I realize the website developers may also be at fault here, but it seems odd that other browsers work, but Firefox does not.

If anyone can offer any help or advice, I am all ears, thanks.

I want to transfer all my bookmarks to another pc. I select export to HTML file and save to a flash drive. I insert the flash drive into the second pc then select 'import and backup' and 'import bookmark from HTML' . Then select the Bookmark.HTML on the flash drive and 'Open'. But no bookmarks ever appear anywhere that I can find. How can I get the bookmarks?

As title- Cannot download for example webm format, but jpg is okay. cannot install any addon, theme or anything. DRM didnt install as well. i was trying reinstall, refreshing browser, rebooting.

I restarted my Windows 11 laptop and got error message about user profile. Restarted again and looks like it was corrupted so deleted my my user profile and Firefox config and bookmarks are gone!

Still have all the files just a new user profile and the old one is gone?

Any help how to get Firefox bookmarks back would be much appreciated

for example: discord.com => discord.com/app

Is there any better way than adding a bookmark for it?

Hi,

So I got a new ultra-ultra wide 32:9 monitor and I noticed when I have firefox maximized on my new monitor and switch focus to a different window all of the text on tabs on the full screened firefox would go very blurry. If I had the same firefox windows full sized on my 16:9 secondary monitor this didn't happen. I then tried having the windows not maximized on the new monitor and it did not do this behavior when it was occupying what I would say was 1/3 of the screen width but if I stretched the screen too far it would again go back to this blurry behavior. So it seems like the text for the tabs behaves differently after the firefox window is stretched to a certain width. On the non-stretched firefox windows the letters simply get darker which I find to look better than the blurring. I added a screenshot that shows the differences I am seeing, the firefox window on the bottom screen shows the blurring, if you look at what would be the left middle side of the screenshot, while the top and bottom middle firefox windows show what it seems like it should look like.

Thanks, Dan

Hello! I installed Firefox about a year ago, and for the entire duration it seems about 60% of the time the default fonts on various websites look weird (bold?). I have tried uninstalling/reinstalling Firefox, clearing the cache, etc. See attached images for examples. Help!

I cannot download any files or any adons through firefox. I have tried every single troubleshooting method in the "What to do if you can't download or save files" article I have restarted my computer, I have refreshed firefox, I have reinstalled firefox TWICE, I have turned off my firewall and tried downloading a file, I have changed the wifi im connected to, I can download files on internet explorer just fine, I have tried a new profile, I have scanned my device for viruses (theres none), I have no idea what the troubleshooting mode is supposed to do because I cannot download files in that either. I currently have no ad-ons installed because of the refresh I dont know what else to do and why is my firefox doing this, it started yesterday.

Hi there,

On the 23. of Mai I first noticed that I am unable to download any files whatsoever. I tried downloading .exe files and also a .csv file. When I try to download one of these files it appears in the downloads window but immediately goes to the status "Failed". Any retry fails as well.

The same thing goes for extensions. I cannot download any extensions or plugins using my Firefox browser. Since I reinstalled Firefox I can now also not use Plex because Firefox can't install the required plugins.

I will attach screenshots of all the errors I get.

All of the above worked when I tried it on the Edge browser.

Firefox version: 126.0 Windows 11

Things I have tried to fix the issue:

• Use the network connection from my phone instead of my home network
• Disable firewall and windows defender
• Reinstall Firefox
• Refresh Firefox
• Downgrade to version 125.0.1 and 122.0
• Reset router to factory settings
• Flush dns
• Restart PC
• Manually delete profile folder
• Delete temp files
• Change download destination
• Disable "Block dangerous and deceptive content"
• Troubleshoot Mode

Is Firefox using some other temporary folder for downloads?

Any ideas on how to fix this issue would be appreciated.

Thank you.

Been using Firefox and predessors for 30 years. The problem: 1. I login to my Credit Union website "https://www.missionfed.com. 2. I AM able to get through the login and verification process, to the page where my accounts are shown. 3. Click on my checking account, and the icon rolls and rolls, and never gets past this point. 4. Access in this same manner has ALWAYS worked in the past. 5. I disabled all extensions, etc. There was only one anyway. Didn't help. 6. I ran troubleshooting / safe mode. Didn't help. 7. Cleared the cache, etc. Didn't help 7. I called the bank. The moment I mentioned Firefox, THEY SAID, IT'S A NEW PROBLEM WITH FIREFOX, WE'RE TELLING EVERYONE TO USE EDGE OR CHROME INSTEAD. That can't be good? 8. The bank said v.125 works fine and that v.126 is the problem. Any ideas?

my firefox browser switches to how it will look on windows 7 for a split second and back to original view, i run it on windows 11 , also when i run multiple firefox windows minimized side by side it often crashes

Im using mozilla for long time but now its nit working https://showpm.com.co/ this site is not opening in mozilla please help me

Images and graphical elements (even the checkmark or the confirm image at the bottom of this thread creation page) disappear when scrolling down. This started after today's update. I've tried creating a new profile, troubleshooting mode, disabling hardware acceleration, disabling dark reader, changing the windows override settings to NEVER - NONE OF IT WORKED!! I'm getting really ticked-off by this crap! Didn't have this problem until the newest "great" update!

How do I turn on autofill in firefox 125/126? There are help pages that say go to settings>privacy> and turn autofill on. But there is no autofill mentioned anywhere in that page. The only reference that autofill comes up with when typed in the search bar in settings is in import settings. How is this so difficult to enable, its basic functionality 10 years ago. I've also tried going to extensions.formautofill.supportedCountries and extensions.formautofill.addresses.supportedCountries and adding my country (why this is a thing is bizarre as well).

I have been facing a very strange situation/bug (likely some addon breaking my Firefox) where I am not able to navigate/load certain sites and certain pages. Here are details:

What is working: 1. I can go to google, amazon, yahoo, and certain other websites home page, and type certain queries in the google.

What is not working: 1. I can't load Duckduckgo(dot)com, nor ddg(dot)gg 2. Though I can open Google(dot)com, but I can not search anything in Google. I can see autocompleted/suggested results in Google, but nothing happens when I click on those autocompleted/suggested queries (screenshot attached, see lower left corner, *.gstatic.com/*.google.com is loading forever). 3. I can't open any addons/extensions. For eg. Tab Session Manager, or even Bitwarden does not load when I click on it, except it shows a pixel on the right corner of addon button on Firefox Toolbar (screenshot attached for that pixel towards the right lower corner of the icon).

What I have tried already - 1. Firefox is up to date as of a few minutes ago. 2. Underlying OS is up-to-date as of a few minutes ago. 3. I have tried disabling all addons and it did fix the problem. 4. I tried changing theme (which was default black) to default, and it did not fix the problem. 5. Tried restarting PC and it did not solve the problem. 6. I tried troubleshooting mode and it DID fix the problem while I was in troubleshooting mode, at least sites were loading. But as I exited troubleshooting mode, addons started loading for a few seconds, and then once Firefox is loaded fully, I started experiencing the same problem. 7. Tried toggle HTTP3 enable/disable, which did not fix the problem. 8. Followed Firefox troubleshooting guides, it did not solve the problem (except troubleshooting mode). I tried disabling hardware acceleration and disabled any protection modes, DNS over HTTPs and other settings which might interfere in site loading - none of that worked.

My hypothesis so far - As I can access some sites on the internet, I have ruled out DNS issues and networking issues. I tried disabling all addons and it did not fix the issue (except when in troubleshooting mode) - which tells me addons are not necessarily a problem. However, I could not find what all things troubleshooting mode disables, and perhaps I should find that out. Could anyone please share any insights or your thoughts on what I might be missing? Firefox is my primary browser and a lot of my tasks are pending from over a day now. Any help is greatly appreciated! Thanks a lot!

I'm an instructor that uses Blackboard at college. When I click in the text entry box to enter my grades, I'm given a list of previously entered grades to choose from. The list is in ascending order. Is there any way to get this list in descending order? One other point, until recently it used to display the value that was used most often at the top, which was often 100. Now it's in ascending order. I've attached a snippet of what I mean.

I just did a clean install on a new windows 11 machine. Every time I close Firefox I get a report crash screen from Firefox. When I close it and restart Firefox everything is fine, but very annoying! I have search every where with no luck for a fix. I did turn off my FSecure which made no difference If it continues I guess after all these years I will have to change browsers,which I don't want to do.
