Firefox Support Forum

I had been using Firefox browser for awhile, but because of playback performance issue, I have to using another browser just for video playing, especially for 4K video.

Compared to Edge, Firefox seems taking more resources to playback the YouTube video and more heat. When look at the Task Manager, the Video Processing is 0%, and GPU is running significantly more resources on '3D'.

An example of the problem: Firefox does not rnder the page https://www.ebay.co.uk/itm/164957094349?_trkparms=amclksrc%3DITM%26aid%3D1110013%26algo%3DHOMESPLICE.SIMRXI%26ao%3D1%26asc%3D238391%26meid%3D7ab2984ab89c490d9d19c64154175f61%26pid%3D101195%26rk%3D5%26rkt%3D24%26sd%3D402300560285%26itm%3D164957094349%26pmt%3D1%26noa%3D0%26pg%3D2047675%26algv%3DSimplAMLv5PairwiseWebNoToraCoCoViewsNoHighIdfOrSortByFinalScoreBlenderWithPromotedViewItems%26brand%3DUnbranded&_trksid=p2047675.c101195.m1851&amdata=cksum%3A1649570943497ab2984ab89c490d9d19c64154175f61%7Cenc%3AAQAGAAABQJxAynw2%252BiqzPDrRSEdA1OtGPHECjXiPIHTAGGaFXyfAhhOOcI0evIqLAV5dzxfkWlXm6ww1t0P09GMtcbSuFZjf5HidAoI3BLEE5q9IzcpZf1TZn1%252BLTOgqc1OD9sLjUiICuetx8VnxmROZ45L3noIgk65aQJuCoPA0d32OWfO52LE5XKsl22M11N9hzVfwHgluh%252F5HKiKhVl5Tsx0wb0b0dE30VWGeE6KisowiOj70Bzel9x4sBW7H8CN3vmNB2XZxJ3WwTx5I56fEAax5jK2zMEYDr0au%252Fk%252FCwLpDP%252BFvJPj2%252BRIxUzguSZgC5le17lkTY6CuGTF9xYRefAzw8ks%252FtcGsNkPKFb7ZfNXkOLe1k28NQbsvOuhPVcLk1pb3Joal6Ssw3egfQv4HF3D4vL6v6k1xWnbVepvH8lGXPENE%7Campid%3APL_CLK%7Cclp%3A2047675&epid=23034767275

properly. A lot of the text comes out in very narrow columns. The problem happens quite often on eBay. Chrome does render it properly. Could you please look into this? Thanks, Jon

Since the latest Firefox, I cannot load Bell Webmail when I am using my VPN. Everything works fine with Edge. I am not tech savvy, but is there something in "settings" that should be adjusted. Bell says that Firefox is the problem. Alan

As per this issue I reported a while back, I was experiencing odd issue with automatic redirect to HTTPS for some private development sites.

I finally found a fix for the issue. The problem appears to be with DuckDuckGo Privacy Essentials Extension which apparently *may automatically redirect to the http site. In order to prevent this, I added my development sites to 'Unprotected Sites' and this prevented DuckDuckGo from doing the automatic redirect to https.

• - Odd thing is that I had multiple domains pointing to the same web instance and only one of the domains was having this issue with the DDG extension. Both were going to the same IP through a HTTP proxy. The proxy and web server were not the issue. This symptom points to an maybe an issue in Firefox....

In summary, be wary of odd redirects and the DuckDuckGo Privacy Essentials extension if you are doing web development work.

When I go to download a ZIP file, it will always attempt to download the file directly rather than letting me open it with WinRAR. When I go into the browser settings I see that some other file types have options to choose how they're handled, but there's no entry for ZIP files. I've tried refreshing my Firefox install and yet the issue still persists.

I used to have this option before I reinstalled Windows a while back (where I kept my files but not programs). I don't know for sure that that's what caused this to start, but the timing would line up.

Hi I have been a user of Firefox for many a year, and this is the first tme I've come across an intrusive problem. Since updating to the latest version, I find I can no longer change the icon on a URL shortcut. I had quite a few of them, which helped distinguish (obviously) what I might want to select. That was then. Now, I have a load of indistinguishable Fireox logos which make finding the shortcut I want imossible. On going to change the icons, I find the Website Document tab in properties is no longer there .. while I have Firfox installed. Remove Firefox and the capability magically returns. I have re-installed Firefox in case of corruption, with no change. Before I remove Firefox permanently (which I'd be loathe to do), does anyone know the cause ... or solution or workaround?

FF updated yesterday with the new Ubuntu 22.04 (Pop) update to 99.01. Since the update the volume control inputs are essentially disabled on all web sites, and they default to max - even when muted.

Example - youtube - all videos play full volume Reddit - even muted videos play full volume

The volume can now only be controlled by the system slider.

The same behavior does not occur in other browsers - e.g. Chromium, Opera, etc.

Can anyone assist?

Hi! Since yesterday, in Outlook, my font size became very tiny for subjects and categories. I can barely see it. Can you please restore them to normal sizes?? I am desperate trying to read them. Thank you! Shirley Savva

I see instructions for sync' to a phone, how do I initially (connect) sync to my desktop from my laptop?

When I sync my bookmarks, how does is know which computer is the primary (the one that I want to duplicate changes from)?

For example, I added new bookmarks and revised some old ones on my laptop and did not have the sync on my desktop at the same time. Now, if I sync my laptop to my desktop, how does it know which device is my primary (in this case my laptop) where I made all the changes?

My goal is to revise all the bookmarks currently on my desktop to reflect all the changes I made to them on my laptop. I'd like to do it without duplicates or displaying old desktop residual bookmarks that I deleted and/or modified on the laptop prior to sync to the desktop.

In this case, should I delete my bookmarks from my desktop and then sync to my laptop so as to seamlessly & efficiently have my bookmarks toolbar on the laptop look the same on the desktop?

Thank you for your help here! Christopher

My problem is this:

If I click on the open new tab button, and then I keep my cursor there, such that I get the little tooltip "Open a new tab (Ctrl+T)..." , Firefox will stop the address bar from updating---it won't show my keyboard inputs, not will it search, or do anything else. This will resolve itself after I move my cursor away from the open new tab button and the tooltip stops showing, even my inputs will appear there.

This quite annoying, especially when opening a tab to search for something quickly...

I have always set my option for all download file types to "Always Ask" and now Firefox not only asks me where I want to save the downloaded file, but also downloads a copy to the Windows Download folder. Why am I getting double downloads? I only want one copy of a downloaded file, not two copies. Now I have to go to my Windows Download folder and delete the duplicate downloaded files. My question is, if my Firefox download option is set for all file types to "Always Ask", then why are you downloading the file twice??? I have specific folders where I want files to reside. I don't want to have to remember to go to my Windows Download folder and delete the duplicate files. How can this duplicate file download problem be fixed?

Long time user, Leo

An error occurred during a connection to www.facebook.com. SSL_ERROR_DC_EXPIRED What in the world? does Facebook not keep up with its own security? or is this a Firefox thing?

The latest example is the button to sign into LinkedIn. It is not working in Firefox, but it does in other browsers. I have other examples just from today. I have used firefox as default for many years. I assume this is a security thing, but these are basic links. I have no add-ons or other complications. Most times, I do not even realize there is a problem, but when I feel something is wrong, I try another browser and it works. Thank you.

Looking for free border designs, and have found the add-on easy search tool required for most of them. Their web site has the add-on for Firefox, but how safe is it? Thanks.

I cannot play CNN videos in Firefox. They will not start. I can play them in Microsoft Edge and on my iPhone. I can play other videos in Firefox from, say, YouTube. It's just CNN that seems to be the problem. I have a Windows 10 PC.
