Firefox 技術支援討論區

I just updated my Firefox browser. Now it doesn't work: "tab is crashed" - an endless chain, always again this.

You should try harder to release bugfree software ...

What about short-time help?

I can't download anything anymore. I get the "failed" message. I see in support questons that this has been going on for a long time even though there have been repeated "fixes" reported. I've used Firefox for a long time and really prefer it, but I'm having to change to Chrome to be able to complete my work.

I suffered a catastrophic crash and had to replace my computer, a mac. I replaced it with another mac.

Because the older one will not boot up, I could not migrate my firefox data.

I ended up doing 'lost password' for all my sites.

There are a couple where the lost password thing hasn't worked.

It occurred to me to rename the (new computer's) logins.json file, copy the old computer's logins.json file from my external backup drive, put it in new computer's /user/library/application support/firefox, and then look in preferences, get the two passwords I want, set things back, enter these passwords into firefox again.

This did not work. In fact, now no matter which file is named logins.json, preferences says I have NO passwords stored.

I cannot find anything that tells me how to just decrypt the .json files (at least, not in a step-by-step way that I can use.)

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.

I am having trouble to open firefox browser for ubuntu 20.04(focal). I have also delete mozilla folder from cache and then reinstalled again. I have tried to rename profileini file. Finally I have uninstall and install using terminal by "sudo apt install firefox" but still I am getting this error "Your Firefox profile cannot be loaded. It may be missing or inaccessible".

How to resolve this.

Thanks in advance.

I received a message from Fire Fox that I should update. Now I have 2 Fire Fox icons and I need to know how to determine which one to delete. Then I need to know how to transfer my favorites and history to the one I keep. They both show favorites and history. I'm a rookie at this so if you can explain step by step it would help, thanks.

I am using Version 113.0.2 (64-bit) and trying to access a home camera system, mydlink.com. When I go to log in there, it tells me "You are using an unsupported browse.....We recommend you use Firefox 12-51/52 ESR on Windows" Can I get this version? What options do I have? Thanks, Ed Corcoran

I wish to install and use the Firefox browser on my old 64bit Windows 7 laptop.

I believe the last v115 will be the last Windows 7 compatible version of Firefox, if this is correct where can I find this or the correct version of Firefox to download and install on my Windows 7 laptop?

The Firefox website only seems to provide v119 now.

Thanks, Graham

Tell me how to "re" install my previous version of 113.02 and then fix this bug. Don't know where to get "old" versions to download and will old version just "install" right over the version installed and keep all the bookmarks, etc.?

I found that Firefox can automatically generate a QR code for each URL, which is a powerful and useful feature! I'd like to know if this QR code has an expiration date.

I wish to export, and not copy, a digital certificate so that I can import it to Keychain on my Mac. The only option in Firefox Browser on Mac is to copy, which means it only opens as a TextEdit and cannot be imported.

Any recommendations?

While I was doing my banking I got an error message saying I was running an older version and needed to update my browser. When I updated to the latest version of Firefox all my bookmarks and passwords got dumped. All of them. I can't find a previous profile to reinstall anywhere or an option to install a previous version. How do I roll this back?

By the way: I AM NOT HAPPY RIGHT NOW!!!!!

I am having trouble importing my info/bookmarks/passwords from Safari

I am following instructions and getting to the point where it says click on safari folder then press open - when I press open nothing happens It just takes me back to the library to click on safari folder again and just keeps doing that

Any advice ?

My PC-Windows 10 crash, I have to reinstall Windows 10 on another partition of HDD. The old windows 10 partition still there with firefox files on that, how can I restore as much as possible from that ?
