Firefox 技術支援討論區

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

The Historic Houses Association (www.historichouses.org) site has an option to show a map of interesting places. When I view this map in Firefox on Android or Windows 11, the icons show up correctly. For instance in the example map, next to Lincoln. In Android/Windows the icon shows a small castle in a drop pin while here in a Linux desktop it just shows a cross hatched box. The link to the web page still works. The roads in the Android/Windows versions correctly show A1, A46 etc. But here in Linux, you can just make out the road numbers behind the vertical hatching. Over a long period I have seen this has occur on a number of sites but I think that the maps are probably (cannot prove it) Mapbox/OpenStreetMap. But when I look at OpenStreeMap it self, the Road Numbers are fine and when I add a layer involving tags, they show as normal.

I know I could address this inquiry HHA but they will simply say 'they do not support Linux'. The site works in other environments so why not Linux? Also, as I have said, it has occurred on other sites in the past (though I must admit I cannot remember which ones and when - I tried a few while writing this support request) Is it likely that the web pages are being downloaded with a catalogue of Icons but this fails in the Linux version of Firefox? Would this account for the road numbers being corrupted as well?

The PC is running a fairly new (last 10 days) installation of Linux Manjaro with Mate desktop. However, this has been happening for some time (a couple of years) during which time, I have used Linux Mint, Debian and Manjaro, with Mate and Gnome desktops. Firefox is used as provided by Linux Manjaro, including Noscript and Adblocker - I have tried viewing this page with both disabled. The only changes I have made to Firefox settings is to enable 'when you open a link .... switch to it immediately', 'search for text when you start typing' and set 'browser.tabs.closeWindowWithLastTab' to false.

I have put up with the problem because it only affects me, however I am about to load Linux Manjaro on to computers for other less computer literate/tolerant people who will be using similar maps. It would help them if I could get a fix.

Thanks for your time

FFox 101.0.1 (64-bit) running in Linux Mint 20.3

Just installed the latest Mint (clean install) and the latest FFox.

FFox tabs are arranged along the bottom of the window! Tabs only appear below the bookmarks panel on the left. On the right, the browser panel is atop the tabs, so the tabs can't be seen. New tabs can't be seen. There appears to be no setting to control top/bottom tab placement -- of course, I want tabs across the top and visible, please. Help!

Also, above "Preferences" > "General" (about:preferences#general), there's an info box that says "Your browser is being managed by your organization". Help!

Regards, Mark.

Hi!

I have Firefox 101.0.1 on Windows 10. When I run firefox normally then everything works fine. When I start another firefox with firefox -P and then selec another profile for another instance then my monitors start to flash black. When I close the other instance then it goes away again.

I tried to update my Intel UHD 630 graphics driver from device manager but it already says I have latest driver.

When I ignore that flashing for too long time I will eventually get BSOD. The driver that causes BSOD seems to be igdkmd64.sys.

What is interesting is that it only happens when I run multiple profiles of FF and once with -P option. With single profile at time I can play multiple videos at once and have multiple large images and other stuff open on tabs that put load on system and nothing happens. Even opening multiple windows within same profile with Ctrl + N doesn't cause any problems. But as soon as I load 2 profiles at the same time I get this problem. Any ideas?

For ‘few a few weeks now the option to choose where to save files has failed, even with the latest 101.0.1 (64-bit) on windows 11 Home. Any ideas?

This evening I changed the default location to my data area, so at least it will hopefully defaulting to ms 'downloads' folder.

OS Name Microsoft Windows 11 Home Version 10.0.22000 Build 22000

i lost my previous tabs and i couldnt recover them. they were no were to be found in history. i need to restore tabs to a previous time or date to recover them and there is no such option, as i accidently closed the new tab and now its overwritten " previous" tabs.

I am getting the error SEC_ERROR_UNKNOWN_CRITICAL_EXTENSION on every page i open. I have looked around and tried to fix it using similar error messages but nothing has worked. I have uninstalled and reinstalled but nothing has worked.

Can anyone help me as there is nothing online that i can find that will fix this.

I have a spare computer I don't use frequently, but which has a synced Firefox installation on it.

I am concerned that as I add and remove bookmarks, it will get further behind and, when it is reconnected, will cause deleted bookmarks to reappear or new bookmarks to disappear. Alternately I'm concerned that the change queue might exceed some size and cause sync to generally fail across my devices. My tablet got "stuck in the past" once and couldn't send or receive new bookmarks despite Sync seemingly working and connected, so I'm worried that perhaps that's what happened already.

On the other hand, if I were to remove that device from Sync, what happens if I were to add it back to Sync?

...If I deleted its bookmarks during or after disconnecting it? I feel like this might cause the bookmarks on my other devices to get deleted too.

...If I don't delete its bookmarks? I feel like this might cause any bookmarks I deleted in the interim to reappear.

Also, is there a maximum size to Sync? I have several thousand bookmarks.

Firefox is asking for a password but I dont have one, (using a 2012 imac). I'm locked out of using my computer. Started 3 days ago and I entered 3 false passwords which opened a window allowing me to quit but now it doesnt matter how many false passwords I enter it wont allow me to access my computer.

I have a habit of keeping a number of pages open to return to under iPhone iOS Firefox. I also generally keep one “current” page open, usually a DuckDuckGo search page, when I close the app, expecting it to come up again immediately when I reopen it. For the past couple of weeks however, reopening Firefox blasts me about 10 miles up into one of my “saved” pages, instead of my “current” one. Why? Why won’t Firefox remember my current page after years of doing so just fine?

I had a partial crash of Firefox browser where some windows with multiple tabs closed. I believe it was caused by my processor overheating. After correcting my processor overheating issue and restarting, the remaining windows that were open before the reboot restored as the previous session but the windows and tabs that crashed did not recover. Would those be backed up anywhere?

It is so annoying that when I open Firefox and type in what I am looking for that my typing goes right to the upper Top of the Page. I have tried to fix this problem but cannot seem to fix it. I want my typing to stay in the middle of the page, but my typing goes right to address bar. I started using Flashpeak, Slimjet browser for this reason. I just cannot get use to what Firefox has done with its browser. Firefox needs to fix this problem, a lot of us do not like it.

I have just switched from Google Chrome to Firefox version 101.01. There is a legitimate website that I use a lot, it is an on-line library where I get eBooks on a regular basis.

Since I switch to Firefox I am not able to successfully get on the website. The website is HTTPS://broward.overdrive.com or HTTPS://www.overdrive.com, a division of the Broward County Library in Florida.

I continue to get the Error code: MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT. When I click “Accept the Risk and Continue button, Firefox then just returns to the original error screen. I noticed it also adds the site to the Firefox Certificate Manger. I had like 20 of the site listed in the certificate manager. I removed all but one, but each time I click the “Accept the Risk and Continue button it adds another exception to the manager but I am still not able to successful reach the site.

I have been using overdrive.com for at least 6 months and it was working with no issues until I switch to Firefox, so the website is not the problem.

I am using Windows 10 as an operating system on my desktop.

Please help me get back my access to this library website.

Thanks, Jim McGuire

In macOS close buttons are located always at left side. Is there an option to move or change close button to the left? Instead of having it to the right like in windows.

Before I signed in, the background color turned to black. I tried to fix the problem by restarting the computer but I don't see the two icons I usually have in the right corner. The computer says hello and it goes to the start page. I need help. Thank you for your assistance.

Hi, As it is, Firefox remember the primary password as long as the software is open and the computer not shut down. This is a very serious security risk! Firefox should forget the primary password after a certain period of time, even when running continuously. At least Firefox should forget the password after the session is suspended or locked. Could you please add this feature in your next release. Sincerely, -- Pierre
