Firefox Support Forum

I am running an iMAC 27 using mac OS X Catalina (10.15.7) When I select Print from the Hamburger drop-down (or by any other method -- I prefer MD + P) I get the familiar printer box but there seems to be NO WAY to see the thumbnail of the page or pages to be printed. For me this is votal because I often print selected pages from a large document or web view.

I am attaching a screen shot of what I get with FIREFOX.

Is this a systemic fault with Firefox or am I just in the dark?

I have to continue to use Firefox 52.0.2 (FF52)because of a discontinued form filler plug-in (Autofill Forms). FF 52 has been working fine until I moved to Big Sur. Upon launching FF52 under Big Sur, the sidebar and some toobar icon drop-menu's text has disappeared. If I boot back into Catalina, this missing text is visible (Please see attached screenshots). I was hoping someone could tell me how to make this text visible again under Big Sur. Thanks in advance for assistance.

I have Firefox in multiple devices. All works except my iMac. Everytime I clean it up. Once I log in on the same mail of the others firefox lockwise wont import the credentials and passwords from the other devices on the same email. I wrote this problem more than once. What is this support if nobody answers related to the problem.

No I have no main password on the firefox yes all the credential options are properly setted that this firefox have to import the other passwords from the device.

Anybody there able to give simple instructions no geek expressions step by step guide AND RELATED to my problem not other things?

Thank you

Question: Is there a way to save the personalized session screen under a reference name?

I have created a screen with some 10 fixed tabs that i use each day in a fixed order. It enables me to quickly swap from 1 tab to another.

In preferences I opted for restore sessions, and it works, but sometimes (e.g. after OSX upgrade) i loose the session set-up and have to re-organize all the tabs again.

Thks in advance for helping me out. EvK

Hi to everyone,

I de-Synced my account and unfortunately click on the dialog box that asked something like Do you want to delete your bookmarks and settings locally stored on your dvices ? So i lost my bookmarks.

My Question is : Does Firefox keep a backup of my bookmarks ? Because I want to restore them on my my browser

I've been trying to access some resources hosted locally with a web extension for testing, but I've been encountering CORS errors. I've added localhost to the permissions field of the extension's manifest.json, but I still encounter the CORS errors. I saw that bugs 1220810 and 1488740 addressed similar bugs in FF84, but Firefox still won't let me send the requests. If it helps at all, I've been trying to access the resources hosted on localhost from an https context, but I was under the impression that those bugs should have fixed that issue?

Ideally I wouldn't need to implement having the server respond with the CORS headers since it only seems to be a problem with Firefox in a local context. Accessing the local resources through Chrome works, and accessing the resources through the internet with the domain name in the permissions field of a production build of the extension's manifest.json works in Firefox. Is there a way to make Firefox disregard CORS enforcement for localhost for temporary extensions?

Hi Folks,

I've recently started working with a Mac (Catalina) and found an oddity that only seems to apply to Firefox. I set up keyboard shortcuts for moving windows between my macbook display and an external monitor using the in-built keyboard options to add shortcuts.

These target the Window>Move to [DISPLAY NAME] menu entries at the top of the screen. For some reason Firefox windows don't have this menu entry and therefore my shortcuts don't move Firefox windows between my screens.

I've included a couple screenshots to demonstrate. It's not a huge deal but I wonder if it's an issue with my machine or just a quirk of Firefox?

Hello,

I have some trouble adding an e-mail address to the monitor service. It seems that the e-mail bounce back. My e-mail provider is asking me if I can provided them with the e-mail sent by firefox, and the received answer, so they could check what is causing it. How could I get those information? Thank you in advance. Best regards, Cyril

Hi, on my MAC M1 (ARM Processor) I have firefox installed. The browser freezes every time I put the computer into sleep mode or when I use the lock screen or simply when I restart the system. Once I have re-logged in to my MAC, the firefox window reopens but all the tabs are locked. So, the only solution is to close the window and reopen a new window. How can I fix it? Thanks

I use the firefox browser with my macos big sur. I disabled the spell check, but I keep on seeing red underlines when I type in the search bar. I thought when spell check is disabled, this should not be possible. (excuse my English). How can I get rid of the red underlines?

Every once in a while the Firefox browser will close down (I'm assuming for an autoupdate) when it does it clears my chosen search engine as well as the information of recently closed tabs and windows. This means that when it restarts I have to search through my history for the sites and pages that I had open before it closed down. Why is this happening? and is there a way I can stop it?

I can't seem to turn off the feature of, when I press delete on accident i go to the past page and this has caused me to leave meetings and other important things, i would like to find out how to turn off this feature.

Hello someone, anyone. I'm trying to import Bookmarks from a Time Machine backup. I've looked everywhere and tried everything I know and I'm not new to computers, although I have not had to import bookmarks in a long time. I'm on an Imac Catalina, backup is on High Sierra, current OS is 10.15.7 Catalina, lost my bookmarks when I upgraded to Catalina because I had to do a clean install. Any help would be greatly appreciate and I may consider putting you in my Will. Robert

Subject line says it all. I am discovering that FF 84.02 just leaves a blank spot where the Flash SWF used to be, making pages super confusing to view if they used to have a SWF on them because you frequently don't even know what the page was supposed to do.

Is there any way to get some sort of placeholder graphic like IE has? Or if not, are there plans to implement one?

Hello everyone,

Firefox Sync sign in is stuck.

Console shows: WebChannel error: No Such Channel Working... Response not received for: fxaccounts:can_link_account

Firefox Browser 84.0.2 on macOS Mojave 10.14.6

I've been having trouble for a couple of months with Firefox. It's on both my desktop and my laptop with both Firefox and Firefox Developer. It seems to happen at random, but instead of being able to see words, all I can see is symbols like these (attached). If I copy/paste it into a word doc or a text file, I can read it just fine. It's only in the browser that I experience these issues.

Has anyone else had these issues? Is there an easy fix that I'm just not seeing?

Thanks for your help in advance!
