Firefox "Print Preview" has disappeared from the File menu in 84.0.2; all I have now is "Print", which brings up a Microsoft Edge style print dialog. Is this an upgrading error, or is it just the way Firefox will be now?

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'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.

I have too many tabs to go through, too many to individually open in synched Mozilla desktop (this process is laborious as there is not a dedicated window for open tab management in synched devices, each time you click one of the synched open tabs it shuts the synchronized tabs box down so going through them all is not feasible, not to mention long as hell!

There is no longer tab management add-ons because Mozilla android is now being "curated" with Mozilla add-ons or something other. So I don't have a one stop solution which will help me to deal with these tabs.

What do I do? Is there a internal tab management system that I can access, copy the URLs to save in text format? This would help a lot. OR... Just let us use the normal add-ons, which you have left available for the desktop version... Like wth?

(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!

I have a problem with YouTube looking in Firefox. When I go to any channel, the header of the channel is not displayed at all, together with its content, i.e. the name of the channel, banner, links, etc. I checked the code by examining the element and I found something like that

1. header, #search-pva, #premium-yva, #feedmodule-PRO, #video-masthead, #watch-buy-urls, #sub-frame-error, #main-frame-error, #watch7-sidebar-ads, #feed-pyv-container, #shelf-pyv-container, #watch-branded-actions, #watch-channel-brand-div, #homepage-chrome-side-promo, #watch-channel-brand-div-text {

   display: none !important;

}

when I unchecked display none, I saw everything normally after refreshing the page as well. I restarted my browser and didn't see the header again. Someone knows how to fix it, because what if it is a bit disturbing and irritating when you can't see it. You can see everything normally in Chrome. I don't want to use Chrome because I don't like it and this browser sucks in my opinion. Thank you for your help on the screen below :)

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."

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

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

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 ?

Hi. I have a new smartphone. Is possible to transfer my collections from my old to my new smartphone and then to synchronize them on the two smartphones ? Thanks a lot.

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.

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!

"When a server requests your personal certificate" my preference is set to "Ask you every time" but Firefox is remembering the certificate I used last time for a site and does not allow me to select a different certificate. How can I change this please? My Firefox browser version is 84.0.2 (64 bit). Thanks

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?
