Firefox 技術支援討論區

So I was sent a picture in .heic format. Trying to open it FF entered an endless loop opening new tabs with names like: "/tmp/pid-949/IMG_9409.heic". There was no easy way to stop it, the 'X' button did nothing. It opened hundreds of tabs. I had to kill all my tabs to get rid of them. BTW there's supposed to be a 'Recover Previous Session' button in the main menu. Not there. On line, I see several different images of what my main menu is supposed to look like but mine is nothing like that. I have 115.6.0esr (64-bit).

Just switched to firefox as my default and found that I can't sign in to netflix. It always gives me the "incorrect password" message. I've tried resetting the password, clearing cookies, restarting, turning the DNS proection off, restarting my computer, etc to no avail. Anyone else have this issue or know a potential solution?

I have Mac 10.12.6 on an "early 2009" 27" iMac. I'm waiting for the new 27/32inch iMac until I upgrade hardware and operating system. The release notes with FF V115 say in part " Users on those operating systems will be migrated to the ESR 115 version of Firefox."

I want to clarify that when I update to FF 116, FF will automatically install the ESR version, or will I need to do this manually? Also, will this update take a long time, like FF will be installing a totally new (ESR) version, rather than "just" the usual update?

I installed one of the ad blockers, I can't remember which one. It's given me so much trouble that I thought to disable or delete it. I deleted the little icon ( a stop sign) that shows up on the far right of one of the menu bars (don't know the name of that bar but here it's the second one down). But websites still complain that I have an ad blocker. I've gone to 'add-ons and themes' but I can't find it. BTW, what's the difference between an add-on, a plug-in and an extension? Which one of those are ad blockers? How can I see and then delete whichever blocker I still have? Without the icon I can't even disable it for individual sites.

When enabling the PiP player window for say a YouTube video from the YouTube website - pressing the 'pause' button on the PiP player window followed by doing any forms of multitasking like opening another window, or opening another program/app or file etc, and then a few seconds later pressing the 'play' button on the PiP player window - it doesn't actually play the video.

You can click the 'play' button over and over and over again but the video in the PiP player window will not play. In order to get the video to play again you have to exit the PiP player window by clicking 'back to tab' and then clicking the 'PiP' icon again.

Using Firefox version 115.0.2

Anyone else experiencing this?

Hi,

I have been trying to use the extension "Sidebery" to replace "Tree Style Tab"

If my tabs are nested, bookmarking the tab tree will give me nested folder structure in firefox's bookmark.

If I right click on the top level folder in the bookmark, select "open all in tabs", firefox will only open those bookmarks in the 1st level folder, but won't open those bookmarks in the nested folders.

I wonder is there a way to do it? That is, open all bookmarks in a folder with those in the nested folder, all at once?

Best, Jake

Hi, i am on linux an Firefox 115.0.2. Every supported website appeared in dark mode because of my preferences in the firefox settings respectively about:config layout.css.prefers-color-scheme.content-override is set to 2 and my system mode is dark. (0 and 3 changes nothing) Since some time this settings does not work anymore. The only thing i have changed is: about:config - privacy.trackingprotection.enabled set to true So now all the websites appeared in dark mode now appear in light mode. Chrome shows all these websites in dark mode. (But of course thats no option :-)) An Example: reddit.com: before: dark, now: light mode, Chrome dark mode. So please help! regards, awilli

The solution for the original Disable F11 (https://support.mozilla.org/en-US/questions/1255696) is no longer working. When the solution is executed from the Browser Console...

doc = Services.wm.getMostRecentWindow("navigator:browser").window.document; if(E=doc.getElementById('key_fullScreen')){E.removeAttribute('keycode');E.removeAttribute('command');}

The return is a reference to "HTLMDocument chrome://browser/content/browser.xhtml" which can be opened up and displays more information.

It used to just come back with something like "Undefined." and then it worked (F11 was disabled for the browser instance). Looks like it just started to not work with this latest version of 115.0 64-bit as this solution has been working for over a couple of years now.

Is there a way to enable this to work in the latest version?

Hi. I have started having trouble accessing some pages that I have reached easily in the past. When I enter the website address, I get the following..

The MediaWiki logo MediaWiki 1.31 internal error

Installing some PHP extensions is required. Required components

You are missing a required extension to PHP that MediaWiki requires to run. Please install:

   mbstring (more information)
   iconv (more information)
   fileinfo (more information)

- an example of the address that produces this result is:

https://wiki.apterous.org/Episode_8050

I am not sure what has gone wrong, or how to fix it. I tried clicking on 'more information' and found some alarming technobabble way beyond my limited comprehension. What is 'mbstring' 'iconv' and 'fileinfo'? - and how do I 'install' them? This site has worked in the past, so I am mystified. Thanks for any help. - John

Please, how can I disable the tab title on hover? After they appear, they stay on the screen even if I switch windows and are extremely annoying. (Work on fedora, gnome)

Is it possible to permanently set a different search engine for private browsing? I have Google set as my search engine in my normal browsing mode, but I'd like the private browser search engine to be permanently set to DuckDuckGo.

(I realise I can manually set it each time to DuckDuckGo but this is tedious.)

With thanks.

i want to know if there is an addblocker built into firefox and if there is how do i remove it because im pretty sure it's messing with a website i use to watch anime

Recently had my FF update to version 115.0 automatically. With the update, watching videos on youtube is impossible. Videos show buffering but never play the video and do not start even with skipping around. Same thing goes for live streams on twitch where the chats will load but not the actual stream. Other videos in news websites appear to be the same. Issue is not resolved in private browsing.

The only icons I can see on the right hand side of my toolbar is the NoScript icon, along with the Save to Pocket, FF Account, Extensions and hamburger buttons.

I should have about 12.

I just installed a new system, launched FF and set it up to sync with my account. Everything else appears to run fine - passwords, history, etc. The Tree Style Tab works fine too.

I have double checked the other solutions I found here, such as private viewing options, or trying to find the icons in the customize screen, but that's not the issue.

My other FF instances on other machines are still fine.

I just updated FF on this problem machine to 115.0.2 but no joy.

Prior to getting some desktop PC upgrades that required a new install of Windows 11 and a new install of Firefox, I backed up my entire PC (yea!).

Now that I have re-installed Firefox, I see that I have none of my saved bookmarks and so I want to restore the Firefox profile - all of it or at least the bookmarks.

I have tried following the Firefox instructions for this, but am apparently not doing it right.

I can't seem to locate the bookmarks file, for starters, in my backed up files. I find the profile but I don't find anything like places.sqlite.

Can someone help me so that I am locating the right (and complete) files, copying them correctly, and then switching to the new/old profile correctly?

Thanks in advance.

hi, something happened to my themes. i can no longer see the preview/thumbnail of them, also the authors link is gone. i've been trying everything for hours, but couldn't find anything in about:config that worked. any help would be great, thanks!

For about a week or so, I am unable to log in to xfinity website, and only the xfinity website using Firefox. I can log in fine using Microsoft Edge. I have tried clearing the cache and turning off Microsoft Defender firewall. I don't use any third party security software - just Microsoft Defender. I also don't use a VPN. I didn't add any new software in the last month, only usual updates from Microsoft and Firefox.

What can I do to fix this?
