Firefox 技術支援討論區

My wife has an older Mac. About a week ago, a pop-up from Firefox told her to update her program. She loaded in the new one and when she tried to open it she got the message that her computer was too old for the update.

We had to reload the most recent update which had been running on her computer.

Now, none of her bookmarks show up and the bookmark toolbar will not display near the top of the screen as it used to.

None of help items online are of any use because what they say will show up on the screen (such as when you enter "about:profiles") is not what shows up on her screen.

Is there any way to recover her bookmarks, passwords and other saved data, please?

I am trying to change the keyboard shortcut of the Tools → Downloads menu (opening up the downloads).

I accidentally click that sometimes and it is quite annoying, so I thought I'll switch the shortcuts to a more complex one to avoid these mistakes ^+⌘+J and when I remap that in the Keyboard preferences, the new shortcuts shows up in the menu, and it starts working but the old shortcut ⌘+J is still working.

I believe that is a bug in Firefox.

Foxfire (100.0) is unstable on my MacBook Air M1 OS 11.3.1. It frequently slows down its loading of site data, to the point of timing out Or simply crashing. At other times it is completely normal.

Of the 3 in the house, this is the one connected to the incoming router from the ISP. The other two are connected by wifi, also using FireFox but completely free of the laptop’s seizing up. I have sent in a dozen FF Crash Reports

Even on the laptop, when slowed down to a crawl, the Ookla speed test shows the ISP’s full connection speed of 250MB/s

The problem has survived: • clearing the OS’s DNS cache • running it on the wifi mesh (disconnected from the Ethernet hardwire)at the other end of the house • refreshing FF using “Troubleshooting Info” • clearing FF StartUp cache • clearing FF Cashed Web Content (which quickly climbs back to ~800MB — is this a reasonable load?)

It is now asking me to confirm whether, with CMD-Q pressed, I really want to quit. I am in HTTPS-only mode, and it fails to recognize an HTTPS url, asking if I want to continue on to the HTTP site.

The laptop has run FF for 16-18 months before this showed up. Possibly at the time when I started to delete all cookies (with exceptions) at quitting FF, and enabling HTTPS-Only mode. But reverting these also makes no difference.

Do I have to ditch FF and use Safari?

the certificate on my linksys lrt 214 router not recognized. used to be able with previous versions to bypass security with advanced tab no longer able to do this cannot use older versions of firefox to bypass. need to access web interface of router at 192.168.1.1 to upgrade certificate but cannot. linksys does not have a work around. please help

Hi, is there any fix for the following? The functionality is intentional but it is absolutely maddening, so I'm hoping there is a plugin workaround or something:

> Pinned tabs are bound to a specific window, so make sure to Quit Firefox while this window is still open and do not simply close a window and leave Firefox running with the menu bar visible.

The user should never be in a position where one simple wrong move obliterates things they've saved (even if it is a recoverable situation). To say 'the user must close windows in a certain order else lose all the tabs they clearly don't want to lose' is just bizarre.

Hi,

I have a very special problem. I have a Macbook Pro (2012) with MacOS 12.4. The old MacBook Pro is not supported by Apple.

Since the update a few days ago, Firefox won't play all videos (for example vimeo.com, youtube.com (not always)). Some videos will be played.

I tried it with deleted cache and website data, with no luck. I tried it with disabled hardware acceleration also with no luck. It also won't work with a new und empty profile (without any extensions).

The sides are loading the video but the playback won't start. Sometimes I get a spinning loading wheel. I suspect the advertising before the videos. Or it is a problem with graphic-libraries from macos, that do not work propper with my MacBook Pro.

With other browser (Chrome, Safari etc.) all videos will be played.

I now, it was my decision to switch to an unsupported OS on my old computer, but everything works (except for Firefox) and I get two more years security updates. I don't want to switch to another browser. :-(

Best regards Kay

I noticed during a firmware download with the file extension .DAT that Firefox removed the extension. The file was not recognizable during an attempted firmware upgrade afterward. This is a new issue occurring sometime in the past several months, since last firmware update. Firefox preferences are set to download .DAT files. No other settings are listed for that file extension. I verified the issue points toward Firefox by checking the download with another web browser which completed the download with the extension.

Hi, my google ads don't display correctly in google searches - can anyone help please? Mac M1 / Latest Firefox

Formatting is fine for the first second after the search, then chanegs and text displays over the images in the ades and is unreadble, unless I hover my moude over the ad.

With thanks

Earlier today I changed my settings in "Privaty & Security" to "Clear history when Firefox closes". In that setting I selected to only delete "Browsing and download history."

I assumed this would just delete my browsing history from the URL bar, but now after I closed Firefox, it also deleted all my tabs!! There were many important tabs that I don't want to lose. But I also can't find them under 'recently closed tabs', and I also tried a solution from this forum, namely to find the recovery file and upload them to https://www.jeffersonscher.com/ffu/scrounger.html -- but they don't contain my old tabs either!

Is there still something I can do to recover my lost tabs??

Firefox is not able to perform any download. It allways get a message saying that the download has failed. I´m completely out of solutions to solve this issue. Francisco

Cannot login to https://www.roadrunnersports.com/ When I put my username & password in I receive back:

"Request failed, Please try again later."

It logs in fine in Chrome, Safari & Opera. Running mac o/s 10.15.7 & FF 100

Since the most current Firefox update in June 2022, when in Yahoo Mail and downloading an attachment, as the download complete, the Yahoo Mail tab is automatically closing, requiring I to go to 'History', then 'Recently Closed' tabs to re-open it. This happens Every.Single.Time I download photos and scanned docs from email. Again, this has never happened before - only with the recent Firefox update. I have 2021 a MacBook Pro.

Any way to try to restore or at least get a list of what my suddenly unrestorable tabs were? I mean, aside from looking through every single item in my entire history and then trying to figure out whether I had already finished that project or not?

(I'll get old and die before I complete that.)

I had many many tabs open, in many many windows, and I discovered long ago (this is not necessarily a good thing:) that if you have the internet on your device shut off while you start firefox up, and while you session restore, though all the urls and the tabs and the windows reappear, none of the are actually loaded, they are just sitting there, and you need to reload each page/tab before the computer seems to use any ram (if that's the word) to run the page. This unfortunately allows a distractable procrastinator like me to accumulate literally thousands of unfinished tabs, which I was of course going through one by one and closing, but I had tons and tons of them open still.

When session restore suddenly no longer is an option, (it is greyed out, and not for the first time,) are there any other options?

I hear mumblings from the web that imply there may be.

such as this?

anything else? or do I have to just give up and start over? (and ON that note, how can I avoid this in the future, there must be some way in lieu of me actually finishing one thing before starting 100 more,) to avoid this?

p.s. getting them back, somehow, would be what I desire, first.

I'm have a problem with the setting for label printing since the last update. I know it's firefox because I went on safari and it worked fine. I have tried to go to firefox print setting, it is marked correct, but it's printing label's 10 times the size. on labels and even on letter size paper. I've tried to restart firefox and my computer. I also checked my computer settings, but firefox is overriding any settings. So what is going on firefox????

It's kind of hard to describe aside from the title.

Only happens when I am using the drop down bookmarks toolbar. When I right-click on an item to bring up the menu, it flickers for an instant, then hides behind the bookmarks drop down menu. Ok, so I guess I could explain it a bit more.

But here's a video showing it more in detail. https://www.loom.com/share/a166451f9354463dbbb6d9faf57df315

I was trying to use the Private Mode with all the extensions disabled to see if that would solve the issue, but alas, it didn't help me isolate anything.

fedex.com has broken my browser!

I have a FedEx account for my business, but I no longer use it. However, I also receive packages from FedEx from time to time. For reasons that cannot be explained by anyone at FedEx, my Firefox browser will not allow me to create a new FedEx account to manage my deliveries. In other words, after I enter my new username & password, the FedEx website comes back with a failure message with words to the effect that, "This didn't work, please refresh your page."

I called FedEx tech support & learned they are now totally incompetent. The only solution that was offered was "Clear all of your browser history". I didn't fall for that - I did however delete all history with "fedex" in the link. I also removed all 31 cookies associated with fedex.com. Then, I re-started the browser, and tried again:

Upon summoning the fedex.com login page, the login information was pre-filled with the userid & password for my old, unused business account! How does this happen without cookies or history? Where is fedex.com getting this data? Is it stored on my browser - or does fedex.com have some nefarious scheme whereby they're using my computer id or IP or???

I need to delete every shred of data in my browser that is associated with FedEx - how do I do this?

Hello, Since a couple of days that I can't drag and drop files from download list window in Firefox anymore. Can anyone help me on this one? Thank you so much in advance.

Firefox 111.0 (64-bit) Ventura 13.2.1

Is there an easy way to downgrade back from the beta channel to stable? The downgrade protection feature seems to be a major blocker of just installing the latest stable version. Noticing high RAM usage on Firefox 100 and crashes which is making it hard to use for a daily web browser.
