I have Firefox 72.0.1 (64-bit) as default browser. I use Google calendar, and Firefox sometimes gives me a mostly empty page, and sometimes works as expected. Chrome always renders the calendar correctly.

Hi, Today i tried opening an PDF, but instead of opening the PDF the page is just blank and it downloads another copy of the PDF. even though the address bar is this: file:///C:/Users/[redacted]/Downloads/[redacted].pdf I tried pasting the address into microsoft edge and there it works fine. I also restarted firefox in safe mode but it has the same problem. I have my windows configured to open PDF's with firefox.exe by default, but clicking on the file in windows file explorer gives the same problem. Does anyone know how to solve this?

Setting up a new LG laptop. Downloaded Flash and Shockwave Flash but they don't appear in my add-ons. Looked on the add-on pages but cannot find any that activate either. I have it on another laptop and it works fine (Shockwave Flash 32.0.r0). Even searched for that exact add-on but it returns no such program. The icon for Flash (on the URL line) doesn't appear on any page. Obviously, I can't play on-line games or watch any content unless Flash is available. FireFox is updated to the latest version as is Win10. Using WebRoot and Malwarebytes. Any ideas as to why this is?

I open a new window, and it says, "Google Search". So I type in a search item, the result comes back from YAHOO search. I have tried several times, without success, to change it, or remove YAHOO Search engine. Yahoo doesn't appear in the engine selections, and google does. I select it, save, restart, and BOOM... I get Yahoo rsults from the google search.... What gives?

Thanks...

Because i didn't find any thread that adresses this exact issue, I wanted to say that I found a solution. If you want to open links in Gmail (with a normal, left click) in a new window, you type about:config in the search bar, accept, then search browser.link.open_newwindow and set the value to 2. This will open clicked Gmail links in new window. If you want to open links in Gmail (with a normal, left click) in a new tab, you type about:config in the search bar, accept, then search browser.link.open_newwindow and set the value to 3. This will open clicked Gmail links in new tab. Hope this helps.

Hi, everybody. I have a problem that I can't solve on my own. In the FAQ or search, I did not find a mention (I could search poorly)

I will try to summarize the essence: immediately after installing Firefox (from www.mozilla.org) on ​​my PC, I tried to enable the synchronization in order to (including) download my extensions that I used previously on other devices. After that, I found that none of them could be installed (they did not even appear in the Add-ons Manager list). In addition, I noticed that the list of recommended add-ons from the Manager's is displayed incorrectly (there are no preview images). When I tried to download a add-on manually from the list by clicking the "+ Add to Firefox" button, I received a pop-up message that "The add-on could not be downloaded of a connection failure" (I use a wired connection (Ethernet) to my PC, without any restrictions. At this point, I was using Chrome in parallel without any problems). I tried to go to (addons.mozilla.org) and found the same behavior. Images were not displayed and extensions were not downloaded (Download failed. Please check your connection.).

What I tried to do to solve the problem: reset the default settings; disable syncing; run in Safe Mode; delete Firefox entirely, and install it again. But all these actions did not solve my problem.

I will be grateful to anyone who can answer me. I'm counting on you.

My PC is used by me and another person and we use vastly different zoom levels. My partner uses about 0.75 and I use 1.25 in Chrome and would like to set similar zoom levels in Firefox. As I use the PC most and I want the default zoom level to be 1.25. I would like to replace the FF level of 1.2 with 1.25 and delete some of the lower zoom levels. A setting of 0.33, 0,5, 0.75., 1.00 and 1.25 to replace the settings up to and including 1.33 would be my desire. I wish to leave the higher zoom levels unchanged.

I understand I can change this in about:config but would like some assistance in doing this.

When I try to download a .dmg file the default is to is to open it with "DiskImageMounter". This is disastrously bad behavior and there seems to be no way to change this insane default.

for the last 2-3 updates everytime I go to start firefox I get a busy cursor and firefox won't open. When I check task manager firefox process is listed but I can not end it. Als a consent ui process appears for a split second, then vanishes, then reappears and vanishes in an infininte cycle untill I log out of windows to force it to close.

I browsed to mozilla install location and deleted the only .xpi I didn't recognise a doh-rollout@mozilla.org.xpi and thankfully I can launch firefox again. As this problem seems to come back every update I'm hoping someone has an explaination and fix.

Firefox 72.0 deleted and a new new version of Firefox installed 72.01 - both this and 72.0 suffered from the same problem in that the library profile file 'Firefox can't find the file at jar:file:///Users/steve_switzer/Library/Application Support/Firefox/Profiles/0fyb29ph.default/extensions/langpack-en-GB@firefox.mozilla.org.xpi!/browser/chrome/en-GB/locale/branding/browserconfig.properties.' cannot be found, don't exist and are not properly created when the 64 bit vwersion of Firefox is installed - Mac is on macOS Catalina 10.15.2 (19C57) Can't seem to fix and get rid of this error Help Please

Hello

Is there some documentation to explain what the font size options mean?

I apologize but I havent studied fonts, I just use the one I feel most comfortable with.

Generally, for me, the font size is too small. And the Adv. page is confusing.

How does the minimum font size relate to the proportional or monospace sizes?

The proportional has serif, sans-serif. The the next 2 opts are serif and sans-serif. Are they related? Because I can set serif to sans-serif and sans-serif to serif.

Att. my settings

thanks agander

I've used prime video since 3 years without problems. From 2 days (14 Jan 2020) the prime video player gives me the error 4315 when I try to start a playback and it does not work. I've tried on different linux machine with the latest upgrade istalled (both SO and browser) and the problem is the same. I've disabled all addons and also the tracking protection of firefox without success. Does someone have the same issue? Any ideas on how to solve? Probably an Amazon problem? Please help me if you can, thanks !

After updating to Firefox 72.0.1, website chat boxes fail to load on blogspot.com. I've tried everything I can think of to solve problem, but nothing works. Any ideas?

I removed my ssd from my Win 7 pro computer and inserted it into an external case. If I plug it into my new Win 10 computer, I can see all my Firefox files - including bookmarks folders - see attached. But the files are all in JSONLZ4 files. I'm now lost. Can anyone tell be how to load these onto my new Win 10 computer?

I have a new copy of Firefox, Version 72.0.1 64bit, installed on a new desktop computer running Windows10 Home Version 1903 64bit and computer is up to date.

Firefox is not my default browser. 

Firefox Windows and Tabs History are set to Default.

For all the many years that I have used Firefox I have closed Ff from EXIT in the menu so that when I restart (from my Windows toolbar or Windows Desktop) all of my open regular windows and tabs are immediately available. Ff still offers this option according to Troubleshooting in Help,see IMAGE 1. Now when I click on EXIT I get a box telling me that I am about to close all windows and tabs, see IMAGE 2.

I prefer not to rely on Restore Previous Session, because in the past if Ff crashed, closed the browser for any technical reason. or if  I closed a window by accident, not all tabs were always restored.

Comparing my knowledge of the workings of computers to a person's knowledge of a car, I would say that I am qualified to drive but not I am not a mechanic; so please word any replies in regular English rather than techie English.

How can I fix this problem, preferably without losing any stored data, please ?

I would really appreciate the community's help.

As above. My guess is I have tool bar on left side of screen and Firefox thinks it is on bottom and leaving room. First image is screen when I expand manually to full size. Second image is what screen looks like after clicking max box. Note second uses default background color I picked. on bottom is part of Word Window that I shouldn't be seeing.

As mentioned above, I have automatic update option switched On in settings and in setting version of my Firefox is written as 72.0.1 64-bytes and claimed to be latest version (some terms might be off I am not sure how they translate to English)... Yet number of Websites like Youtube, Deviantart or even function like reCAPTCHA claims that I am using outdated version making browsing more difficult to me in various ways, I did receive several messages about my browser being updated and forced Update few times, but problem does persist for LONG while despite that... what's going on really?

This has happened one other time in the past but the problem went away and i dont remember what I did, but the problem is back. Firefox is saving my login info for email sites and amazon and the dropdown with saved login even shows on private browsing windows. The Logins and Passwords and Forms and Autofills are all unchecked and I have checked to make sure there weren't logins or passwords or Forms data saved.

Attached is a dummy login that I used in yahoo mail and a screeshot of my Firefox privacy settings.

I recently tried a Mozilla.cfg and Local-setting.js fix to prevent saving passwords permanently on the browser but that did help either

I have consistently used Firefox as my browser and had no trouble using Ancestry.co.uk.

Over the past couple of weeks, it seems there are parts of Ancestry's functionality that no longer work with Firefox. When I first experienced the issue I tried to do the same operations using Bing, and there was no problem - so it seems the problem lies with Firefox.

Any ideas?
