Firefox 技術支援討論區

I've read some complaints about the font that FF desktop uses on some websites. I'm seeing a very annoying font with some letters thicker (almost bold) and other letters thin. This occurs, for example, on the mozilla.org website and when FF is displaying a PDF.

I have "allow pages to choose their own fonts" checked, and I am not using hardware acceleration.

I went into the developer console and turned off the Mozilla-supplied font for a support webpage, and it then used something like a Times New Roman, but it was uniform in letter thickness.

I have attached screen snips.

If I display the same page using Chrome, the font looks great, so I don't know exactly what the problem is, but it's clearly a FF problem.

Notice in Chrome that the word "garbled" is in bold, and it does not appear in bold in either of the FF font examples.

When I access Task Manager from the Firefox menu or just type about:performance the screen comes up, but it only shows information for Task Manager itself (low impact) but doesn't show information about open tabs / websites or add-ons. I was trying to use it to see if one of my open tabs was impacting browser performance. I have the latest version of Firefox.

(I have bad English, sorry.) Hello! May I ask? Is it possible to officially download older versions of the FireFox browser? And at the same time that they work and open sites. Just, I have an old netbook, in general, all new browsers do not work well. Thank you in advance for your answer!

On 84.0.2 on OSx.

Firefox will offer to save usernames and passwords, but then does not remember them in the future. Attempting to import existing data from another browser into Lockwise prompts a request to set a primary password first. Attempting to set a primary password (which is currently not set), yields the error message "Unable to change primary password."

Dear all,

I am planning a move towards the Firefox ESR 78.6.x. Currently my customer is using the Firefox Rapid Release 84.x and need your help with the profile migration. The customer has a very isolated on-premises environment and does not allow the users to login into a Firefox-Account. Therefore the settings for Cookies, Cache, History and especially Bookmarks are not synched.

Environment details:

• Enterprise environment with several tausends of clients
• All clients on Windows 10 Enterprise between 1809 and 20H2
• All clients have always the newest Firefox installed currently 84.x

This creates a huge challenge to sync this stuff. Therefore I have now identified the following two options:

1. 1 Allow the downgrade by using the environment variable MOZ_ALLOW_DOWNGRADE on Windows. For this option I am trying to find the real reason why this "Downgrade-Stop" has been implemented in the first place? What risks in detail do I take to allow this downgrade? Has anybody done this before and do you mind to share your experience here? How many issues did you face and how did you remediate the issues?

1. 2 Hand over the migration to the users. Copy their current profile to their desktop and ask them to import their bookmarks manually. Not preferred by users and I can't even blame them for.

Is there any other way to automatically sync the profiles from 84.x to ESR 78.6.x without user interaction?

Thanks in advance Amir

I know how to bookmark a page- what I want to know is how to restore the bookmark star in the address bar (I accidentally removed it). I KNOW that you can bookmark a page by clicking the 3 dots at the end of the address bar and using the drop down menu, etc, or key commands.

BUT- I want to RESTORE the star that easily and quickly allowed you to bookmark a page. All other answers to this same question seem to only tell people alternate ways to bookmark a page. I don't need that. I need to know how to restore bookmark star to address bar. Thanks! my firefox ver is 84.0.1 64bit

I love having the Clear Cache icon so easily accessible, but why must it also refresh whatever page I am on??? Just now it caused the page to revert to one that had none of the articles on it, I was just looking at! This is supposed to be a helpful feature, not one that screws things up.

please advise which compression algorithm is used when saving browser console command history in the ~/.mozilla/firefox/xxx.default-release/storage/permanent/indexeddb+++fx-devtools/idb/xxx.sqlite ?

Wow... I just updated and am trying to use Firefox as my default browser yet again, however, yet again, it's RAM usage is ruining an otherwise good relationship. Why does this browser guzzle RAM so hungrily? I had to reboot it as I couldn't type any longer, without waiting every few letters before seeing them on the screen, and I've got 60 Gigs of RAM. But Firefox was using 22 of them!

This has obviously been an ongoing issue for years, both from my experience, and the 2,000 threads that come up in response to this issue. Come on guys, it can't be this impossible to create a functional browser that is more RAM efficient, what's the problem?

Oh, and it sure would be nice, given 2,000 results from my search, to be able to filter them by date. I'm using version 84, so threads dealing with version 50 or so, aren't going to be of much help...

I'm on an iMac running Big Sur 11.4 and Firefox 84.0. When I click on an external hyperlink (say from an email), a new Firefox window opens to my home page even though there is already a Firefox window open. There is only one tab in the new Firefox window (not two like previously reported) - the home page. This does not happen when I switch to Safari. In preferences, I have "open links in tabs instead of new windows" checked. This just started a few months ago. Also, in the example email, when i hover over the hyperlink, a little downarrow box appears to the right of the link. When I click on the down arrow, a window opens with the proper link, but it's not a Firefox window. At the top of this new window, there is a box that says "open with Safari". When I click on it, it takes me to a new Firefox window with only the home page tab. ????

Since the last update from Firefox to my tablet (Windows 10), the on-screen keyboard is displayed briefly when you select it in the toolbar, but then disappears again immediately, making an entry impossible! This phenomenon only occurs with Firefox, all other browsers and programs work perfectly with the on-screen keyboard!

I recently purchased a Mac M1, coming from a Windows / Linux environment. After installing Firefox, it requires an icon on my desktop to run. Then, every time I reboot, Firefox no longer recognizes me. My pins, history, etc. are all gone and I have to re-organize everything again.

Can you please help?

Hey There!

I have set photos.google.com to automatically open in a tab container called "Google."

Now I would like remove this automatic function, as i might be opening that website in different container tab, since i have a mutipule google accounts spread across different google accounts.

Is there a way to remove or unlearn the "Always Open This Tab in a Container" for a specific domain?

As far as I can tell you can only change the container the automatically opens, but you can't just unlearn it.

Any suggestions?

Maybe add a unlearn option to the menu in the attached picture?

Hello, i would like to report that every newer version of Firefox Browser after version 84 periodically freezes (hangs), the freeze continues indefinitely, until i shut down the browser with Task Manager. In version 85, support in Mozilla Firefox for Flash was discontinued as far as i know, so this may have some connection with the problem. The freezes happen (occasionally) when i try to open some of the menus, such as history, help, view, edit, file, etc.

The issue gets fixed when hardware acceleration is disabled, so this may have something to do with a lack of Firefox compatibility in its newest versions with the video driver. Unfortunately, the browser becomes too slow and laggy when HA is disabled, so this is not a working solution for me.

Using older video drivers also does not help, the issue occurs only with Firefox Browser versions after 84. I do not have such issues with other browsers.

Config:

Windows 7 64 bit Video card Nvidia GT 750 Titanium

The problem occurs with Firefox Browser - all versions after 84, plus with all drivers for the video card

I never get the same problem with the same hardware on Win 10 (it is a dual boot computer with Win7 and Win10 OS). There newer versions of Firefox work normally.

So if you have time, please forward this report to the Mozilla bug fix team.

All was good until sometime today. FF 84.0.2 W10 up to date. Previously, when browsing FB marketplace, i could send a message about an item for sale. That send message button is now greyed out. The messenger button on the top right of my screen used to open a dropdown/popup that gave me a summary of my messages. That no longer works. I have been thru all kinds of settings randomly on FF and FB to try and correct the issue but i cannot figure out what is going on. I have tried turning Ublock on and off but that has not helped either. The only access i now have to messenger is to open it separately. I have not changed any FB settings. I did not change any FF settings myself other than trying to find out what could be doing this and exploring ublock for possibilities as that seemed the most likely culprit. Can anyone shed some light on what the issue is.
