Firefox 技術支援討論區

Since about two months ago, I haven't been able to update Firefox(or any other browser for that matter). I've tried the typical method of going to Preferences, checking for updates, but I can't get passed that point. I get this error message stating "Failed to check for updates."

Chrome was giving me much of the same issue, I've allowed GoogleUpdate on my firewall rules, restarted the PC and tried again. Still got the same error message. I have no other antivirus software installed on this device other than the Windows Defender default app. Firefox hasn't told what I should be allowing past my firewall so I haven't tried anything similar for Firefox.

I also tried uninstalling Firefox, but when I tried to reinstall, I couldn't finish that process because clicking on Download Now led me to this error message stating "Hmm. We’re having trouble finding that site.

We can’t connect to the server at download.mozilla.org."

I assumed this was maybe a DNS issue. I tried a DNS flush but that also was ineffective. I tried changing my DNS servers to 1.1.1.1 and 1.1.1.2, also tried other known DNS servers but that didn't work either.

In the meantime, I'd like to at least get an offline installer going because my current version is 110.0.1.

Thank you.

My FF updated to 110.0.1 (64-bit) on Ubuntu and several things which use to work really well are now broken.

For example, when making a new account, the password manager pops up asking if you want to save the username/password, but if you mouse over to that popup then as soon as you enter it it just disappears. When logging in somewhere, if there are multiple choices for userid (say with different dates) none can be chosen. You mouse down to the popup with the choices and there's a weird stroboscopic action where the popup disappears and is recreated as fast as it can, over and over, and nothing can actually be clicked on. If you type in the userid then try to enter the password the same thing happens. It's not possible to use the password manager anymore, both fields need to be typed in manually.

Another example is the search field. If you type something and there are several options from previous searches, and you try to mouse down to pick one, the popup disappears. If you click the search keyword again it highlights as for replacement, then you have to click it again (removing highlight) and only then can you mouse down and choose a search engine.

etc etc etc! All this stuff worked great until the upgrade happened (in the background) and now many things are a huge pain in the ass. Arrgh!

% uname -a Linux spunky 5.4.0-144-generic #161~18.04.1-Ubuntu SMP Fri Feb 10 15:55:22 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

I tried disabling all add-ons then restarted but made no difference. Password manager is unusable.

So at some point today, my bookmarks toolbar changed. nothing is missing. it just now has a massive blank space to the side that I cannot remove. Does anyone know how to fix this? See attached image for what I'm talking about. nothing I try removes that huge gap to the left.

Please help me with reason for why Firefox connecting CDN servers such as amazon, google is not security threat for customer data?

thanks Samvedna

I've tried resolving this issue after looking at various solutions here on this site as well as other sites. The message "Your browser is being managed by your organization" shows in my settings, However, when I go to the Policies thread in the registry - whether it's under Local Machine or Local User - there is no policy registry entry for Firefox or Mozilla.

Please advise. This is really annoying.

Thanks in advance.

I want to setup Firefox with different settings when I use Private Mode.

When using Private Mode, I want my browser history, cookies and downlods all to be deleted when I close the window.

I can see a way of doing this for ALL uses of Firefox, but not just for Private Mode.

Any help, gratefully recevied. Thank you.

When I click on "Google Apps" in Firefox (with links to Calendar, news etc.) says "can't load". When I try with Chrome is loads fine. What can be done to fix that?

I want to stop Firefox from silently updating in the background during browsing sessions. When it finishes updating like this, currently open tabs stop working and I can no longer open new tabs. The only fix is to restart Firefox. This is a problem if I am, for instance, going through a set of web forms as the information I enter will then be deleted and I have to start again.

When I have used Firefox on Windows, the requirement to restart Firefox to install updates has always been indicated by some change to the settings button on the top right of the window. With Ubuntu, the update is downloaded and installed without any action from my part, and given that it is quite disruptive this is unacceptable.

I have tried a number of ways of changing this, none of which work. Under the general settings tab, there are no options for changing the way updates are handled. Settings under about:config appear to do nothing. I have app.update.auto set to false, and app.update.notifyDuringDownload is set to true. I have attempted to circumvent these by setting a policy using the policies.json:

{

 "policies": {
   "DisableAppUpdate": true,
   "AppAutoUpdate": false,
   "BackgroundAppUpdate": false
 }

}

None of these have made the slightest change to how Firefox handles updates.

I am running Firefox 110.0.1 (64 bit) on Ubuntu 20.04.5 LTS, but I should point out that this has been a problem for the last several years of Firefox versions on the same OS.

Running Firefox 110.0.1 (64-bit) on Windows 11 Pro.

Spell check does not work. No red underlining of spelling mistakes. It is enabled and about:config confirms it. This happened to me a couple of times under Windows 10 and much older versions of Firefox. This is a recurring theme without a one-stop resolution.

Anyone? Thanks

I cannot access about config, I want to stop my searches from being forced to the address bar, I have just bought a new laptop, and synced it with my other laptop, it offered me search from address bar, and I avoided it having experianced it before, yet when I opened firefox again I was stuck with it.

There are a number of threads/articles on this, such as: https://support.mozilla.org/en-US/questions/1341031

They don't include that if "Clear History when Firefox is Closed" is checked, that even though settings are set to open previous tabs, everything is lost. There are options for that setting but it has wiped out my previous sessions a few times with no recovery available. I have always forgotten which setting does that even when it happens, so am hoping the threads/articles will be updated to include it for fixing the problem. It seems these settings are in conflict though and not clear. If Open Previous Windows and Tabs is set to on, I think it should override wiping people's tabs out in other settings that are buried or not as intuitive.

I'm on Firefox 110.0.1 (64-bit) and running in troubleshoot mode. Under settings, I have "Portable Document Format (PDF)" configured to "Open in Firefox". Some PDF documents show up as blank for ~27 seconds, but show up immediately on Chrome.

I've downloaded an installation guide PDF file from the store.ui.com website.

For example, you can look at the doorbell camera: https://store.ui.com/collections/unifi-protect/products/g4-doorbell-pro Then select instructions and manuals to expand the PDF files available.

Hi there,

I refreshed Mozilla Firefox because reCAPTCHA was not working client side. Doing this fixed that. HOWEVER, my passwords did not carry over. I had them Synced and everything, but upon refreshing Firefox they are all gone. I need them stored in Firefox or I will not be able to login to any of my accounts. The sync function seems to not be working either (unless I am using it wrong). Most were securely generated passwords. Not memorable ones.

I saw that refreshing would remove certain things like extensions, but it said it would keep bookmarks, passwords, etc. I have my booksmarks, just zero passwords. HELP!

I need them for work today. Can you assist please!?

Appreciated, Tyler
