Firefox 技術支援討論區

Is there a preference in about:config to fake or simply block websites from reading the font-list of my operatingsystem? I think it is pretty ridiculous anyways that websites can access this information since it has nothing todo with the webbrowser visiting the site but going beyond to spy on information that i consider private.

Same question goes for audio-readout, is there a pref to fake or block?

This is going to be long sorry. A lot has transpired

My son was using 78.15esr. I upgraded it to 91.3esr. After the upgrade the browser worked; tabs loaded, surfing was fine, could go into settings and about:config was fine.

He went to watch something on Netflix. Netflix complained his browser was not supported and he needed to upgrade to the latest version - which at the time was 91.3esr.

In frustration he installed Chrome. When he tried to run it he was told software restrictions were in place. I had not set any restrictions, and I checked secpol.msc and there were definitely no path rules defined. If restrictions can be set in group policy I had not set them because I am unaware of them.

So he installed Microsoft Edge, which installed VC runtime for 2013 and 2015-2019 for both x64 and x86.

At that point Firefox no longer loads tabs at all. About:<anything> doesn't work. Settings doesn't work. You can't go to safe mode (more on that later), and when closing the browser two processes remain taking about 60 seconds to end.

I did have the group policy templates for Firefox installed. When I upgraded to FF 91 I installed the latest templates.

A couple of times when I started FF it complained about vcruntime140 was missing. But just running FF again worked without doing anything else.

So I reverted to 78.15; I uninstalled v91.3esr. I deleted his profiles.ini and profiles folder and then copied them back from a back up. I removed any registry settings, and copied back the v78 ADML files. I then installed v78.15esr with internet disconnected. Did not run FF after install. Went into group policy editor and turned off telemetry and auto updates then re-enabled internet

Run FF and same issue. tabs not loading. Pages not loading. I can click on a menu and I can type into navbar and search bar but there is no response. I checked internet was working.

I deleted the %LOCALAPPDATA% cache folders. I flushed the DNS cache. None of this worked.

So I uninstalled FF again, deleted the profile folders and ini. Disconnected from Internet. Deleted any registry settings, and removed the group policy templates. Then installed 78.15 from scratch and let it create a new profile.

Same darn problem. It seems to me that installing chrome and/or edge has done something nasty, but I have no idea what. I say that because before he did that he could surf the web, but Netflix just said his browser ver was outdated.

I tried contacting netflix on chat but they were worse than useless.

So I uninstalled again and removed everything. Connected the internet and installed FF again and let it update automatically. Same problem.

I've left him with edge but I need to fix FF.

I even uninstalled the VCLibs, Chrome and Edge. These did not fix the problem.

I tried safe mode but when firefox restarts there are two processes that take 60+ seconds to end so FF sits there saying "restarting...". When those processes finally end Firefox does not restart.

Checked for viruses; nothing found. Rebooted PC several times.

So at this point in time; FF will run but will not load the 3 tabs; Facebook, Netflix and youtube. They stay blank. Settings is not accessable, nor is addon's or logins and passwords. Typing anything on the search bar does nothing Typing anything in the address bar does noting Trying about:config or about:profile or any other about's does nothing. When closing FF two processes take 60+ seconds to end.

If I go back to him and tell him I need to reinstall Windows he will go absolutely nuts.

What also worries me is that Netflix said that the most recent esr browser version was not supported and that he should update to a later version.

And what is even more troubling is I updated his girlfriends PC at the same time and hers works perfectly. This scares the hell out of me because I then expect responses like "Your sons problem is not a firefox problem".

My Firefox bookmark menus are often taller than my screen.

When I select a bookmark well down in the current menu by typing a letter, for example "T", the menu display scrolls down to the first matching choice, but that choice can be mostly covered by the down-caret indicating more choices further down. I can see the top of the highlight for the current choice, but I can't read the text of the choice.

Not a big deal, but I'm hoping it's an easy fix. Thank you!

On this site: https://www.orange.pl/twojekonto/zaloguj I can't force firefox to remember username (no problem with remembering password on next step). In older Firefox without WebEx there was addon which allowed to manipulate forms to prepare proper autocompletion data. This addon is not supported with WebEx anymore due to lack of proper functions. Instead Firefox Dev Team claims that mechanism built in current Firefox is enough for such tasks and mentioned addons are not needed. Seems it is wrong thinking.

I tried different approaches to save username for mentioned site but without success.

My tabs toolbar does not extend across the entire laptop screen. Looks like it stops halfway, regardless of how many tabs are open. As tab number increases individual tab space narrows. How can I increase width to occupy full screen?

Hi everyone,

I am running Firefox 91.5 on Red Hat Enterprise Linux 8.5 and just noticed that all my addons have been disabled and can't re-enable them.

Some of them are quite common modules such as Disconnect or Privacy Badger, so wondering what this may be.

There is a similar post on this forum dating back to 2019 and it mentioned a fix on Firefox was to be developped.

Anyone experiencing the same issue at the moment.?

Please see attached screenshot.

Kind regards,

Alex

defaultPref("privacy.window.maxInnerWidth", 1000); defaultPref("privacy.window.maxInnerHeight", 1000);

Instead of 1000 what is the default value Firefox uses?

In other 'apps' on windows 10 the tooltip is above the pointer or below it. In Firefox it is directly under the mouse. So usually any tooltip popup in firefox is unreadable, mostly. One can infer the content sometimes.

How do i change that? Or what is the problem?

I'll try and include a screenshot. Hmm, the screenshot didn't include the mouse. I think i can do a video with OBS and then a screenshot of that.

Interesting, somehow in the screenshot from the obs video it shows 2 mouse pointers. One is very small and the tooltip is just below that, but the other is larger (the one I see) and it covers the tooltip. I'm using the standard windows mouse settings for larger mouse pointers. I just tried using the 'old' mouse settings to select a larger mouse and it behaves the same way. If I select size: 1 in the new size settings, and the old settings i have 'windows system' mouse, then the tooltip is under the pointer but the size is too small for the pointer. I then changed to another mouse setting in the old selector "inverted extra large" and you can see the tooltip because of the 'inverted' nature of the pointer, but the tooltip is still partially covered by the pointer.

Ideally the choice would be to put the tooltip above the mouse pointer rather than below. When you increase the size of the mouse pointer it only increases down, not up. The point of the pointer is always at the top.

I'm going to try one more thing, increasing the size in the new settings after having selected "inverted", but i recall that it changes to the new pointer style. Ah, there is an inverted setting in the new options as well, and if i select that instead of the gray color i was using then one can read the tooltip through the mouse.

So, then my question becomes "can I put the tooltip above the mouse pointer?" Because it is still covered by the mouse pointer as is. I don't see anything in 'about:config', so far.

Thank you.

When video/audio starts playing on a browser, the tab title displays 'playing' text. This additional line resizes the window height and causes the tab content to resize too. For example youtube starts resizing video window height and width - and this is very annoying. How do I remove 'playing' text from tab FOREVER?

I have an account on usps.com (the post office). Using FireFox, I am unable to see or use my address book on that site. USPS tech support says it's there and also says FireFox is the most problematic web browser of all. USPS tech support says to use ANYTHING but Firefox.

Yes, I have cleared my cache and cookies multiple times in an effort to solve the problem. And doing so does not solve the problem.

I can use IE or Chrome to access USPS.com and I can see my address book!

What the heck, Mozilla?

Hello,

I did some changes to the browser according to a privacy guide: https://restoreprivacy.com/firefox-privacy/

When I now watch a video, while the overlay is there, the over a third of the video height is full of green horizontal stripes.

I can't figure out which change to the browser leads to this.

Do you have any idea?

When I want a URL, I type it in the address bar. Search has no relevance to a URL, and any intervention of Search gets in the way, and creates errors.

When I click in the search bar, it's because I want a keyword search with one of the search engines. A search is not a URL.

They are two completely different things, and treating either one as the other is error. I do not want Firefox to kidnap my cursor and teleport it to somewhere I didn't click. They are two entirely different spaces, they are not interchangeable. When I click in the search bar, it's because I want a search. Don't you dare second guess me and change my click to the address bar.

How do I turn off this stupid stupid stupid error behavior of FIrefox?

I tried this and it didn't work. In about:config • keyword.enabled and toggle it from True to False. • browser.fixup.alternate.enabled and toggle it from True to False.

Hello My Firefox browser stopped working suddenly. I used it this morning (11/12/21) without issue but when I tried it around 6PM CST US I got PR_CONNECT_RESET_ERROR on everything I tried to load. There was no updates that I am aware of and I tried all of the solutions provided on sites I visited up to and including disabling anti-virus with no success. For now I've uninstalled the product until a solution has been found. Thank you to anyone who may be able to assist in this problem. All other browsers I've tried work as expected.

Hello,

I'm using Firefox 91.4.1esr (64-bit) from Debian repositories on Bullseye. Every time I open Firefox, a window with a greeting message appears ("Say hello to a new Firefox"), and it doesn't matter if, as asked by that window, I choose a theme or not. Is this issue related to my settings? Is this a Debian issue? Is it possible to stop that window from reappearing?

Thanks in advance. And many thanks for making Firefox (I've been using it for so many years I can't recall when I tried it for the first time).

Hello,

I have 3 different profiles and I'd like to have a visual indication of the currently active profile. I've found that using themes is the best option (a red theme for production, green for test, grey for default) but I can't prevent Firefox Sync to sync the active theme between my profiles.

I have set both services.sync.prefs.sync.extensions.activeThemeID and services.sync.prefs.sync.lightweightThemes to false and restarted all my Firefox profiles.

After a while, all windows/profiles are synced to the same theme.

Are those settings really read by Firefox Sync ? I'm on Windows 10, Firefox 91.10.0esr (32-bit)

Thanks in advance for your help !

fresh install RHEL 8.5 FF 91.2.0esr

i start a vid in youtube. the sound has static. if i open another window, even on a site that doesn't play video or sound, the sound and picture on the first window instantly get out of sync. the picture runs about 2-3 seconds ahead of the audio.

i have not customized the setup. this is a "stock" configuration. i have lots up upload, download speed. 20Mbps up, 80Mbps down.
