When I try to load a png file with transparent background into firefox 35.0.1, the background appears black. I've already tried Transparent standalone images add-on with no results, including https://addons.mozilla.org/en-US/firefox/addon/transparent-standalone-image/reviews/?utm_source=firefox-browser&utm_medium=firefox-browser&utm_content=addons-manager-reviews-link and https://addons.mozilla.org/en-US/firefox/addon/transparent-standalone-images/reviews/?utm_source=firefox-browser&utm_medium=firefox-browser&utm_content=addons-manager-reviews-link

I also look at the previous question with the same name, from 2015: https://support.mozilla.org/en-US/questions/1044582#question-reply

Unfortunately after trying to follow every step there, I have the same question as the OP did on 2/3/2015, except that the extension he recommends ( Old Default Image Style: https://addons.mozilla.org/firefox/addon/old-default-image-style/ ) and the other two recommended by cor-el ( Transparent standalone images: https://addons.mozilla.org/firefox/addon/transparent-standalone-imag/ and Custom Standalone Image Backgrounds: https://addons.mozilla.org/firefox/addon/custom-image-backgrounds/ ) are all dead links in 2022.

I would appreciate some help with this.

Since your last update I can no longer view my credit card statements, it downloads a pdf file. If I go to download the pdf instead I receive four pdf files downloaded. The edge and brave browsers don't do this.

Hi Windows 10 21h2 Firefox 100.0 When pasting images from the clipboard into a website (atlassian confluence for example) firefox uses a generic image name (grafik.png) instead of the actual filename. This started to happend a few weeks ago. I was not able to find a demo page where this can be tested, other browsers don't have this issue.

Anyone having similiar issues or an idea how to fix it?

Thanks

Good day.

My use case is the following. I use Firefox Developer Edition for developing websites. Usually the development happens on a certain part of the page. Most of the times it is not on the top of the page, so you have to scroll down to it.

Sometimes when the page is refreshed a jump to the top happens. So then I need to scroll down again. It takes a lot of time and concentration away if it happens dozens of times a day.

It often happens after I did some changes to the files on the page. It usually does not happen when I refresh the page a couple of times (when I purpously want to reproduce this problem).

I did try running Firefox in Safe mode, but it didn't help.

What can be done to fix this problem on my side? Is this a bug in Firefox itself?

Hello, I recently migrated to a new MAC and now when I download a file and click on "show all downloads", it opens the about:downloads tab and not the downloads list from the library. Is there any way to force Firefox to open the Library when I click on see all download please? Thanks

We have a full stack "MEAN"(CosmosDb/mongoDB, Nodejs, Express and Angular 12) project hosted on Microsoft Azure. Somehow today I tried to log into the app with my favorite browser Firefox and got stuck. Looked at the developer console and saw a bunch of exceptions. I tried our app running on various browsers: Chrome, Opera, Edge, Brave. They all work fine. Furthermore my local server also works with Firebox browser. What could be my issue? Please help.

Thanks so much!

On my new desktop I want to enable the feature that does the following.

I want to be able to view a webpage and then ctrl click or M3 click a link and I want the new link to open in a new tab but REMAIN on the current webpage.

I have unticked >When you open a link, image or media in a new tab, switch to it immediately under settings already.

Hi!

I am not sure, if Mozilla is the reason, or Facebook is the reason. But since I can't get any help from FB, I'd like to check also here.

At first, I thought that the problem is on my side, since I am using ICC profiles and maybe I did something wrong. But It is not the problem on my side. I tried with an original jpg file, directly from my camera.

So, when I upload JPG to the Facebook, color of the image changes. This happens only if I publish it directly to my FB wall. If I go to FB "publishing tools" (on FB pages), everything works normal. If I upload the same photo via for example Chrome or Vivaldi, everything works, even if I upload directly to the FB wall.

So the problem occurs only If I upload from Mozilla (I have latest version 100) to the FB wall. Not via "publishing tools" on FB page. But problem is the same if I publish on my FB business page wall. So I assume that the problem is on FB side, that somehow renders files differently then via their Publishing tools. But I am allowing that Mozilla does something to them via the interface.

There must be some problem with Mozilla too, since all images work OK with Chrome or Vivaldi. So, something in relation of Mozilla - Facebook wall.

Currently I just use Chrome for uploading to FB, but I don't want that.

Not sure what to do now. FB does not reply, maybe Mozilla can help or check? I attached a sample photos, to see difference. Here is my Mozilla gfx.color profile too: https://i.ibb.co/CWRHWnh/6.jpg

Good Day All, My RCN Webmail login website is not being fully resolved because the full login URL is changed. Since RCN is being merged with Astound I now must choose between them before getting the login page. I change it but it wont save it with the sub URL /support/email/rcn-webmail/ intact & unlike KevP's solution, @ https://support.mozilla.org/yo/questions/1360318 my page is not a frame & doesn't seem to be a redirection issue that I can tell either. Does any one know how I can troubleshoot this ? Thanks in Advance for any contributions.

Seems like after installing the latest update Firefox will not allow Amazon to function or display properly after signing in to Amazon. I can sign in using any other browser with no issue. When I sign in on Firefox the screen goes greyed out with no functionality capable. Nothing can be selected and in the background the display won't load correctly.

I have tried all of the suggestions and cannot find any backup files other then current dates. Now I am without my bookmarks clear back to 5/7/2022???? HELP!!!!!!!!!!!!

I am wondering if it is at all possible to adjust the settings when pulling a tab into a new window. For example, if I am running Firefox fullscreen I would like the tab that I pull to be opened in windowed form. I noticed that this is typically the case when using Chromium-based browsers, but noticed that on Firefox it stays in the format as the previous window. (if already windowed the pulled tab will also be windowed) is there a way to ensure that the pulled tab will always be windowed?

it happens after upgarde to v.100 every click in the link in thunderbird starts only new empty FF window instead of the link content in a new tab This is not on the thunderbird side, as when I set Chromium as default browser the link is opened correctly.

This is a maddening bug! I know it started with the recent update to Firefox 100 because the behavior only started AFTER updating and I did not change ANY settings in Windows 10, let alone any related to the keyboard. Please fix this bug!!

I double-checked this setting for Backspace key navigation. Here's what I did:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

(2) In the search box in the page, type or paste browser.backspace_action and pause while the list is filtered

When I did this I saw the value was set to 2 (do nothing) so something else is causing this bug!

I followed instructions for getting them back, but got stuck at the Library. I said restore and chose a date, but I get an error message: Unable to process the backup file.

I have several credit cards saved in Firefox. When I try to use the "Autofill Card Details" feature, I am prompted to authenticate my identity with my user password (that is, computer user account password). Upon entering the password, the prompt accepts it and disappears. Now, the expected behavior is that Firefox should paste my card number, along with other details (name on card, etc), into the corresponding fields. Instead, it enters blanks into all the text fields, clearing them if they had previously had anything in them. After this, if I go into settings and view saved cards - the cards that I have attempted to autofill are shown in the list of saved cards, but have blanks in all text fields.

I have had to re-enter all the card details several times over. I have encountered this bug many times at this point. Tried searching for posts with similar problems but have not found anything.

new firefox user trying to migrate from chrome i want to bookmark my trello board but it is not using the right icon. it is using the generic trello icon instead of the one that is actually visible when i have them open. i use 3 different trello boards and need all 3 to be distinguishable only by the icon so this is a critical feature for me to be able to use this browser. this problem doesn't happen in chrome which i have been using. i have tried many extensions to try to locate the image that is actually being used, it doesn't work. i can't find the image being downloaded. how do i get the same icon that is showing in the tab to show up in the bookmarks bar?

Running Firefox 100.0 on Linux Mint 20.3 Mate 1.26 I've noticed that websites like my bank use a "sub window" that slides in from the right to display the running balances. Prior to version 100, this worked perfectly with dual scroll bars, one for the main window and one for the "sub" window. Now, with version 100, the "sub" window has no scroll bar. I can control the window by using the keyboard up/down arrows, but the scroll bar for the "sub" window is non existent. You cannot have access to my bank account, but you can duplicate the problem with Google. Simply search for say, a celebrity, click on one of the displayed images, and the window that displays on the right used to have it's own scroll bar, beside the bar that controlled the main window. Sub window scroll bar is now gone. It seems you folks violated one of the Cardinal Sins of Programming: IF IT AIN'T BROKE, DON'T FIX IT. Scroll bars worked great before, Not sure whose idea it was to "improve" them. Rolling a Firefox update backwards is a logistical nightmare. Is there a possibility of a fix coming out soon or are we to live with this as a "feature"??? Thanks for your time.
