Hello! Short story: I recently discovered that adding a new GIF image to a page resets the animations of existing GIF images on the page with the same src.

Expected behavior: Adding a new GIF image to the page should not reset the animation of existing images with same src.

Actual result: Adding a new GIF image to the page resets the animation of all existing GIF images on the page with same src.

Code with example: https://codesandbox.io/s/heuristic-platform-jsguir Video demo: https://www.youtube.com/watch?v=k-ZMrrqq_KI

Simplified version of the code showing unexpected behavior: https://codesandbox.io/s/elastic-shtern-vwrcx1

Does anyone know why this is happening? Is this a bug?

Browser: Firefox Developer Edition 102.0b4 (64-bit) OS: Windows 11

When I have FF open, then close all windows but still have FF active, I hit CMD-T or CMD-N to bring up a new tab or window and nothing happens. I repeat, repeat, repeat and still nothing. THEN if I click on the FF icon in my dock, all the tabs and windows appear in a cascade of windows or tabs like bam, bam, bam.....

This happens on two MacBook Pros around 2016 vintage. This is a new behavior this week.

MacBook Pro OS High Sierra Firefox version: 106.0b4

When I bring up Google Maps I put the address in and Firefox shows an error message. This has been happening for a couple of months. See Error Message below.. Google Chrome has NO problem pulling up the address. How can I fix this? Thank you.

I've got about 10 bookmarks with links to support pages each about adjusting specific about:config setting to my needs. My job also requires me to change systems lots of times, from Mac to windows to Linux. Is there an easy way I can save my personal about:config changes to a file for easy import on other systems?

Thanks

I saw many tutorials on making self-signed certificates get a lock sign of trusted certificate, which were installing the root certificate of authority in firefox which i did, and also installed in windows, i am using latest version of firefox developer edition, this is error i recieve:

Websites prove their identity via certificates. Firefox Developer Edition does not trust this site because it uses a certificate that is not valid for 192.168.0.102. The certificate is only valid for the following names: localhost, 192.168.0.102, 172.20.10.3

Hi,

I hope you are well.

I have set up 11 custom devices that max the min and max sizes of bootstrap grid system (xs-min-360w, xs-max-575, etc) to aid me with checking my website on various screen sizes. Is there anyway to export this list or better still to synch them with my Firefox account so I don't lose these settings?

I am using Firefox Developer Edition (101.0b6 (64-bit)) on Ubuntu 20.04.

Many thanks Kaz

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?

if there's not already an option to autohide the bookmarks toolbar (like the address bar and tabs when in F11 mode [fullscreen])

can there be?

so like, on default the bookmark toolbar wouldn't show, but when I move my mouse into the specified area it appears (with the same animation as f11 mode)

 thank you,

let me know if i can already do that and if I'm just dumb.

 just to be clear, I want the tabs and url/address bar and tabs to always be there.

Actually might be cool to have options to autohide the tab bar too (separately).

 thanks again,

graham

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?

After updating to 106.0 (64-bit), I'm seeing an error when trying to open the new tab page ("Oops, something went wrong loading this content.")

Troubleshooting mode does not help.

The browser console shows the following error:

TypeError: sectionOrder is undefined

I suspect that the new tab page is not correctly handling the preferences I have set.

MacOS FF dev edition 102 When I roll my mouse over a link, in pops up the URL in the bottom left (i.e. status bar as safari calls it) but there's no indication of if the link will show in the current tab or a new tab. in safari, the end of the URL states "in new tab" if that's the case.

When I type my website in the bar, firefox puts www in front of it, which causes the warning page: firefox detected a potential security threat and did not continue to www.karinchappell.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

If I remove the www by backspacing it, the page loads correctly.

I've checked the website: "SSL is enabled on your site, and an SSL certificate was detected on your site."

When I've asked around the techies I know, I've been told this is an antiquated way of dealing with it. Please advise.

At computer boot I start: Firefox -silent -profile myProfile after I normally start: Firefox -profile myProfile and I get error: We’re having trouble getting your pages back. Not problem when start subsequently. Why? to it is possible to solve it?

I just had a glitch with the latest update to 102b, FF insisted I had an old version and would only let me make a new profile. So I had to set up multi-account containers again. I have specific sites opening up in each container, and I'd like to make a copy to make sure that if my profile gets goofed up somehow, I can always easily restore my setup with multiaccount containers just the way I like it.

What do I need to copy, so that with a new profile, all I need to do is copy over some files?

In my profile folder, I see an Extensions folder, as well as an extensions.json and extensions-settings.json.

Are those the only folders/files I'd need to restore multi-account containers on a new profile?

I have thought of using FF Sync, but I keep reading that it is not intended for copying, so much as sharing across different devices, which is not something I'm interested in. Should I just let sync copy my extensions, and then sign back in, in the event I want to restore addons to a new profile?

While watching videos(movies/anime) video takes much time to buffer. If video is of 20 minutes then it loads first few minutes then after watch time reaches that buffered video then it takes more time buffer.

What I am looking is for, how can I force firefox to buffer full video at once or is there any way to increase buffer size.

Somewhere around September 6 something changed in Firefox which prevents me from accessing my control area for a website I own. The error says: " your connection to this site is not private. Information ...". I am the only person with access to this site and my password to the site is 20 characters long with special character and randomly generate. Everything worked well and doesn't work on any computer in my house. This change in your software is costing me money as I can't work on my website. I am not a happy camper. Please tell me how to resolve this problem. Telling me to ask the hosting company to make changes is not a valid response.

The URL in the URL bar is trimmed. I went to about:config and disabled "browser.urlbar.trimURLs", but it still did not work after I restarted Firefox. (see images)

Firefox version: 105.0 (on beta update channel)

I later then found out that there is a lot of unused space on the right. (see https://1drv.ms/v/s!Ag9_47ED3j7sgsZhkB02k7gI3lavyg) How do I remove / make use of the space on the right of the URL bar? How do I turn off the trimming of the URL?

Any help is appreciated!

please take off the red add, the pop up total add sign that keeps popping up asking to paid for the add block I am 82 and on a fixed budget. I do not want this service. How do I get it off my computer. When I want to print an article from an e mail.I always have to remove it to save an e mail, or when I want to print an article, I read it later, and I see the total ad block on my printed article stuck on the printed page blocking out what I printed. Its very annoying to have to take it off the screen before I print anything. Please help me. George at [removed email from public]
