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?

Apparently Mozilla did an update and not it defaults to it's own printer dialog box. I hate it. There is a link to use the system print dialog box but it only works for that specific print job. I can't find a setting to force Firefox to always use the system printer dialog box. Anyone know how to fix this? It's enough to make me stop using the browser becasue thr Firefox dialog box sucks.

Hi, first of thanks for reading and possibly responding.

The issue I am having has been going on for a few days. In websites where youtube video's are embedded if I try and play the video on the said site it will load and display an error message An error occurred. Please try again later. If I visit the video on youtube, link provided in the video itself, then it plays just fine. Error is not restricted to one site but anything that embeds youtube videos.

I have also come across some strange youtube.com issues, when I am on the main website you get the thumbnails of video's but no time duration are displayed in the thumbnail, neither are the 3 dots where you can have one of the videos removed (not a big deal and maybe this was implemented a while ago I don't know tbh). When I play a video, as in visit the video page on youtube the side bar videos sometimes do and sometimes don't display time duration.

Please check attached image to see what I mean. Left is without said timecodes, right is what it almost should be.

What addons do I use: Ublock Origin is the only one worth noting but even without it the weird thing still occurs. I don't use any plug ins that correspond with youtube.

I am using the latest Firefox on Windows 10.

Things I have tried thus far to resolve it: - make sure Firefox is up to date - try with and without addblocker (Ublock) - remove Adobe flash entirely - refresh Firefox and clear all data and cookies 9tried this I think 3 times now, no change) - looked through older posts with similar issues but most links regarding html5 on youtube were 404 and sometimes the solution stated things like 'cause by some video helped addon' which I do not use or updating Flash

Am I the only one with this issue?

Today, when I go to print out a web page, the format of the Print Preview window has changed and the"Simplify Page" option is missing. I use this feature all the time. Without it many pages are impossible to print. How can I restore this feature?

Hello, I would like to know how to remove 'other bookmarks' folder from the right side of bookmark toolbar that showed up suddenly on my browser, it's right after the arrows to show more bookmarks. I can't seem to find a way to delete this.

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

For the first time after 10 years, I can no longer access my PNC bank account using Firefox V84.0.2. This problem started just this Sunday Jan 24, 2021. I am using AVG and the Defender firewall. When I try to enter my account PNC tells me that it cannot find the code and tells me to use another browser like Chrome or Internet Explorer which I don't want to do. PNC tell me to contact Firefox as, "It is not their problem." But so far I have found nothing in Firefox to solve the issue whatever is causing it. I need help as I would rather not change browsers.

I have restarted my PC, checked and restarted AVG, checked the troubleshooting program, and reinstalled Firefox, but nothing seems to correct the problem. So where do I go from here?

How can I get a list of all the sites that are set to "always open" in a specific container? For example, I want to see a list of all the sites set to always open in the Work container. I would also like to edit the list without needing to manually visit each site.

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.

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 have open half a dozen or so tabs related to one subject. I would like to put them all into one "super tab", such that only the super tab shows as an open tab. Then, by clicking on that tab, it would show the tabs within it, any one or more of which could be selected. Is this possible, and if so how is it done? Perhaps there's an add-on or extension that would do this.

I have already created a multi-tab bookmark that sorta, maybe accomplishes the same thing. But it's not as convenient as what I envision as described above.

Thanks for any advice or words of wisdom.

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.

Been having this issue for the last few weeks where Firefox just won't load YouTube properly. In particular, livestreams won't play, chat always show as "disconnected from chat" and I can't even access the profile menu (clicking on my profile pic on the top left just shows a loading icon forever).

Tried the following without any luck: 1. Safemode 2. Clearing all cache 3. Refresh firefox (When I first did a refresh, it started working again, then I went to sleep and the next morning the same problem is back again)

Any help would be much appreciated.

Attached is a sample of how web pages display. These can either initially display this way or, as in this example, the page opened correctly, I stepped away for a few minutes and when I viewed the page again it looked like the example. I can have a page open and it is displaying correctly, then open a new tab and go to a different site and the text will look like the example.

I have cleared the cache, dumped all the cookies. Restarting the browser (I do this many times a day) will fix the current page but eventually another page will display like this.

I running version 84.0.2 64bit on a Mac Pro Mojave. I don't have this problem with other browsers like Chrome or Safari. I never see it on my Windows 10 system.

dear ladies and gentlemen,

Firefox has been delivered with the new print dialog since version 82.

I have to print around a hundred PDF files at work (usually only the first page of the document). The new print dialog means that there is a lot more work for me here.

Is it possible to set the "old" system print dialog by default or to instruct firefox to always print only the first page of the document by default?

Dashlane Password Manager has been working as an extension on Firefox on my Acer Aspire E5-571 laptop, but for an unknown reason it has disappeared from my toolbar. When searching for 'Dashlane' on the Firefox browser to install the extension on my browser, nothing relating to 'Dashlane' can be foound.

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.

I am using Firefox 84.0.2 (64-bit) on Win 10 Pro and the menu font size and toolbar icons are minuscule, even on my 32" monitor.

I found a fix for this same problem in Thunderbird, but I don't see any way to make the menu fonts and toolbar icons bigger in Firefox. This has nothing to do with web sites, just the menu/bookmarks, toolbar icons, etc.

Thank you.
