Firefox 技術支援討論區

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

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?

I am very happy with the upgraded Firefox library. It works great except for one feature. Maybe there is a setting for it that I have missed.

When I click on an item in my library to open it, it opens it over top of the right-most tab that I have open. That means I always have to be careful to have a blank tab open, otherwise I lose the last item I was viewing. Is there a setting, or can you add a setting, to have the library open links in a new tab, or if one prefers in the existing tab? I want to be able to open in new tabs.

I would like to put an individual tag onto my bookmarks toolbar. This StackExchange answer from years ago seems to suggest that it should be possible just like putting the Tags category onto the toolbar. However, I am not able to do that for an individual tag, even though I can for the whole Tags category.

Is it possible to put an individual tag onto the toolbar? If so, how would I do that?

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?

I am receiving the message Did Not Connect: Potential Security Issue ... requires a secure connection ... when trying to access my Shopify website AngelFallsHomes.com. This ONLY happens with Firefox; all other browsers are working fine. What do I do to fix this because obviously it is a huge concern.

I recently started experiencing errors for logging into third-party websites that use Google sign-in.

On one site (coches.net), I have the sign-in popup loop for like 3 times and then disappear but leaves me unlogged.

On the other site (etoro.com), the sign-in popup shows but then I get an error message from the site about the login. Then it won't let me reconnect since CloudFlare won't accept my "I'm not a robot" prompt and keeps reloading the same page.

This started happening yesterday. I'm not aware of any Firefox or Anti-Virus updates that have happened since, measures not existing yesterday.

I can sign-in correctly from Chrome with no issues.

Hi everyone, When i go to the website config.office.com in firefox there is just a white screen. Nothing more. Instantly white. I have checked if this is an issue at the side of Microsoft but it doesn't look like it is. The website does load correctly in Microsoft Edge.

I tried the following in Firefox: - Firefox is up to date (Version 115.0.2 64 Bits) , I have had this issue in other versions of Firefox too. It's not a new issue in this newest version. - Tried disabling all the security features in Firefox, disabling all add-ons, and disabling the extra security for cookies - Starting firefox in safe mode (Shift click on firefox, then open the website) - Checked the Network inspector. All packets have status 200 (See the first screenshot)

You can check the second screenshot for the white page.

Some help is appreciated :) Thanks!

Any extensions I install suddenly don't show up in my toolbar or the customization menu anymore, so I also can't drag them there manually.

Deleting the extensions and re-installing them didn't work, neither did deleting the extensions folder itself.

Does anyone know how I can fix this? I've attached a screenshot of the customization menu and extensions menu below.

Thanks :)

So I'm using firefox on my old PC and want to export the login data to my new PC. Firefox has export passwords to CSV but there is no import CSV in firefox on the new PC. There's import HTML but... firefox exported to CSV not HTML so I'm really confused, why would it export to a format that cannot be import?

Is there a shortcut to deattach tabs from one browser window so it turns into seperate window, so that you don't need to deattach tabs with clicking and dragging them with mouse?

This issue is so annoying, that I need to ask Firefox community what I can do. So, the problem is, that if I set custom home page called Infinity New Tab (Pro), then I will restart Firefox, then it reverts back to Firefox Home.

I think, that this is completely unrelated to malware, because I'm scanning my computer very often.

Are my preferences/settings corrupted?

However the Infinity New Tab (Pro) is no longer available in addons.mozilla.org, so if you need .xpi file, then tell me, and I will attach that file here.

Firefox is downloading files directly to my Downloads folder instead of asking despite having turned on every setting that says it should ask first. Under about:preferences I have turned on "Always ask you where to save files" under Downloads, and I have set Applications to "Ask whether to open or save files". I have even gone in to about:config and turned off "browser.download.useDownloadDir", but the files are still going directly to my default folder.

I'd like to be able to prevent a specific address from appearing in the Firefox address bar (as a suggestion) when I start to type in the address bar. I tried deleting the cookies associated with a particular address, but the address still appears as a suggestion in the address bar when I start typing its name. Thanks a lot for any help.

Here is a sample URL that works on Microsoft Edge (current version) and receives an error message on Firefox (115.0.2): https://www.t-mobile.com/home-internet The error received from the web site when using FF is:

Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

FF was working with all T-Mobile pages a few months ago and now fails with this same error on most pages.

To test on Edge, I pasted the identical address that failed in FF into Edge and it worked fine so I am confident I am comparing the same web page on the two browsers.

Thanks for your help. Claude
