Firefox Support Forum

Firefox is my primary browser. I get this Network protocol error message so often now that I am considering using another web browser. See below It happens with sites I routinely use. I have tried several of the solutions from Firefox and also searched other solutions online to no avail. I like the Firefox web browser. Can you provide me some other solutions

Network Protocol Error An error occurred during a connection to xxxxxxxxxxxxxxx. The page you are trying to view cannot be shown because an error in the network protocol was detected. • Please contact the website owners to inform them of this problem.

While following this step in order to reduce CPU and memory consumption of firefox [content-prefs.sqlite file], I accidently deleted the Profile folder itself.

After this firefox wasn't opening and was stuck on not responding in activity monitor.

I reinstalled firefox, multiple times even after a shutdown, removing any old files in the Library folder. Still it's stuck on the same issue, firefox doesn't opens up even once.

Hello, I closed my browser, expecting it to save my current tabs as it usually does. When I reopened it, the tabs were gone. They were important for me, and some of them were pretty old so I can't find them in my history. I tried checking the "recently closed tabs" option, it didn't help. There was also no option to restore the previous session. Can you help me restore my lost tabs?

Hello, I am using Firefox for my company. We are using Quickbase system to access the data from internal server. Previously, I can allow Firefox to show the image that classified as unsecured context. I could see the setting option to allow unsecured pictures. But now I changed my account on my computer and when I use firefox, I can not see the image file from server and also I can not find how to allow unsecure picture. Is there way to set to allow unsecure stuff from Firefox? Please let me know.

Thanks

Daniel

I am having problems playing a particularly demanding video from YouTube (https://youtu.be/-W_nFlIAWFM) which runs at 4K/30 fps. It is a video taken from a drone flying over the Matterhorn in Europe. Here is my configuration: 1. I have a 200Mb connection to the internet and bandwidth testing confirms that it runs at a consistent 195 - 202 Mb. 2. I am using Firefox 126.0 on a dual boot machine running Ubuntu 22.04 LTS and Windows 10 (both OSes show similar stuttering and pausing). 3. My hardware is a Gigabyte Aorus Z690i motherboard with 32 GB of RAM and an Intel i5-12600K processor and an NVidia GeFroce RTX 2060 Super graphics card. I have tried disabling "Use hardware acceleration" in Firefox and also disabling all add-ons and rebooting. This hasn't resolved the problem. When I watch the same video in Google Chrome, it seems to display a much slower frame rate than 30fps but doesn't stutter. I have concluded that this video must be a super demanding one to render. There are many picture elements changing constantly. But is there a way to watch this at 4K/30fps with it playing smoothly and at the correct frame rate?

I've migrated to Firefox from Chrome and am getting everything as close as possible to my Chrome setup. This is a usability issue when I zoom on an image, that has a larger version. Chrome allows me to zoom to the full extent of the image, but Firefox screen shakes and doesn't allow the same detail. Screen recording and links below.

I am curious as to why Mozilla/Firefox doesn't seem interested in matching Chrome for addons for popular dropshipping apps such as CJDropshipping, DSers and AutoDS. These are well catered for in Chrome and allow easy import of products into stores such as Shopify. They save a lot of time for already busy store owners and staff yet Firefox loyalists are forced to switch over and use Chrome to make life easier and save time. For someone who has been using Firefox across both Linux and Windows since it's 2004 launch, it is galling and almost physically debillitating to have to resort to this each time. If I were any good at coding I would surely fix this serious shortcomming.

Please Mozilla look to this and provide us with better options.

How to change the background we want on the Mozilla Firefox front screen, as I gave the picture

It seems firefox has changed the behavior of tabs. When I go to open a closed tab, I see a list of all the tabs that have been closed from every window. I want to restore the previous behavior where "recently closed tabs" only shows the tabs that were closed in the current window. I saw some about:config settings, but I'm not sure what they do and I don't want to end up losing the tab history all together.

Thanks

Hey,

Is it possible to disable a specific shortcut or change its assigned other keys?

I wanted to disable the "Moves the URL left or right". It turns out that this functionality won't be useful to me, but this shortcut is the one that I use the most :/

Hello, I was using Firefox to read my email at privateemail.com. When I attempted to save one of the emails to my Macbook (using an option in the window displaying the email), Firefox launched Apple Mail on my MacOS system. Apple Mail opened up with the email in one of its windows.

That is not the way it worked in the past. When picking "save to computer" in the web-mail interface, Firefox would open a SaveAs dialog box and allow me to directly save the mail to my computer.

I tested this behavior using Safari instead of Firefox, and that behaved as I expected. That is, Safari opened a SaveAs dialog box for me to use.

Is there a configuration parameter that was changed in a recent Firefox update? I am running FF 126.0 on MacOS 14.4.1.

Kind Regards, Brian Kowalski

Firefox was running in full screen. Without me doing anything it reduced it's size to about 1/4 screen. Everything I attempted to correct this has not worked . Any thoughts or suggestions on how to correct this is appreciated.

Thanks guys for screwing up my day with your latest update. I used to be able to download a .pdf and opening it in my ,pdf reader. I NEED to do this for tax reconciliation purposes. Now your crappy program has decided to open .pdfs in itself and I cant get a downloaded copy any more. What the hell was the programmer thinking? Yes I have gone to Applications and checked that it is set to my .pdf reader. Please fix this before I get fined by the tax office.

Hi, there - Over the last few months, I've noticed some things that make it impossible to get to websites. I keep getting "Secure Connection Failed," for example, with getting to Chewy.com. I just tried to sign into the ssa.gov website, but it comes back repeatedly as "403 forbidden." And another big one is trying to get to outlook.com. It never fully loads. I cannot get my email. I've been having to use Edge more and more, and I don't like that for privacy issues. Also, sometimes I cannot finish buying things on some websites without changing over to private browsing. Thanks.

When updating Firefox, I my Avast antivirus often pops up with a Threat Secured window: Is there some nefarious code in your updater? I attached a screen grab of the warning window.

The plus sign in the tab bar has always been on the far right side. I reloaded Firefox yesterday and now the plus sign is directly after the tab. How do I get the plus sign back to where I like it?

I am in the process of migrating to a new Windows 11 PC. I am a long-time user of Firefox and have version 126.0 - 64 bit on my old PC. On my new PC I apparently downloaded it from the Microsoft Store during all my software installs. That version shows as "Windows MSIX Package Mozilla – MSIX – 1.0”

Are there differences between the 2 versions and should I do anything such as reinstalling from Mozilla?

Thanks, BillT
