I am trying to access certain HTTPS websites and some of them show PR_CONNECT_RESET_ERROR in Firefox. This error is not present in Edge or Chromium.

Here's what I've tried (none of these works):

• DNS over HTTPS turned off
• Uninstall all add-ons
• Reinstall Firefox
• Create new profile and set it as default
• Delete/rename certs.db in the Firefox profiles folder.

The only fix that works is to use Troubleshoot Mode every time I visit these websites which is not practical. Any ideas on what could be the problem?

I don't know if this is relevant but one of the websites that does not work is https://alexan.com.ph/

I had Firefox installed and working perfectly fine , but I had to factory rest my MSI laptop (windows 11 home) because I had suspect suspicious files I needed to get rid of, after the new install of Firefox each time I try to sign into a google account I would be able to type 2/3 letters and then Firefox crashes and closes down , I had uninstall and downloaded a fresh install from the microsoft store

See attached screenshot. It just randomly happens from time to time, and I can't figure out what's causing it. I've used both Chrome and Firefox with the same results. Help!

Recently when I try to download a file Firefox seems to give it a random amount of time before it attempts to open the file. For small files this isn't a problem, as it always seems to give at least a few seconds, but larger files get cut off. This leaves the file corrupted/incomplete.

I have no idea why is started doing this. Just one day it started opening everything I downloaded, be it PDF, image etc when complete. I turned this off and it has stopped for things that download properly, but it's still doing this 'cut off' attempt to open.

Any help would be appreciated, thanks,

There's a problem with video playback on firefox, where after a while/randomly, the thing happens as shown in the image. I've uninstalled intel graphics driver and reinstall, didn't work, I've refreshed firefox, didn't work, I've fully uninstalled firefox and reinstall, didn't work, and when the error occurs the igpu is at 100% usage (and ram/vram usage is not full). The whole firefox app will be laggy but not windows, and upon pausing the video only will firefox be free of lag, and a refresh will solve the issue. However, it will occur again once in a while, doesn't matter the resolution or volume, and not just youtube but all other video players. It does occur more frequently and predictably when the video is paused for some time, or when the computer sleeps for a while, and I think it has something to do with the way firefox handles ram. (just my guess)

The only fix that worked was setting media.wmf.dxva.d3d11.enabled to false, which is undesirable as it increases cpu usage by at least 20% as well as increasing my battery discharge. Other fix includes using other browsers, using my nvidia rtx on firefox, and (not totally sure) setting the resolution lower.

Also, after the error occurs/before the error occurs, firefox doesn't do that blink-in-blink-out animation when going fullscreen on video players (like chrome), which can be fixed by exiting the firefox application completely and restarting it. Refresh doesn't work here.

Why is my credit card blocked on my favourite shopping site? Everything was fine until the end of December. My cards are not blocked by the bank or Visa or Mastercard. I've checked many times. A site I haven't used for 6 months isn't a problem. How do I correct this? Thanks for reading this. I hope you can help. I appreciate that you are here. Marcia Green

I have two computers. Both sign into the same Firefox account. Both instances of Firefox are the same version (134.0.1 64-bit).

On my main computer, creating a new tab is set to Firefox Home (default), and clicking the "+" sign to create a new tab results in the recommendations appearing as seen in the first image (firefox_2025-01-19_17-42-57.png)

On the other computer, creating a new tab is set to Firefox Home (default), and clicking the "+" sign to create a new tab results in the recommendations appearing as seen in the second image (firefox_2025-01-19_17-43-57.png)

How to I get both instances of Firefox to do the same thing when creating a new tab, i.e. organize the recommendations like the second image?

When I type in the search bar, for example, 3+3 (also tried 3 + 3), when I enter, it will give me this "3 3" and will just show results instead of the calculator.

It, however, still work normally if I were to write "3 plus 3"

I have always had Firefox as my browser (senior citizen - desktop pc for 12 years. Yesterday everything worked fine, and today nothing works! I have done nothing to cause this - no kids, animals, etc. Please help me and restore my F.F. browser and all settings! I am really lost and cannot reach all my financial accounts, Email etc. mws15@verizon.net PLEASE help if you can! Mary Scott - mws15@verizon.net

A while back I posted: Firefox NO LONGER adheres to "Ask if you want to Save" option..." Somehow - it was fixed after I posted - so I am trying again.

ALL my Application settings are correct - It says the browser is up to date - I am Windows 11 - Laptop. I don't know if it was an update that was just applied - I think it must be - As this was FINE yesterday - but NOW - When it press save - it automatically saves to a Download folder - It WILL NOT let me CHOOSE where to save. AND as you know in Settings, It says WHERE to save "DOWNLOADS" - you CAN change that - BUT - EVERY SAVE is DIfferent - I CAN'T and have NEVER saved something in the same folder every time - This was NEVER a problem - Just TODAY - so it has to be some upgrade that happened when I rebooted my laptop today. I have attached a screen grab - so you can see I have almost EVERYTHING as ALWAYS ASK - including Microsoft Word. HELP!!

Sessionstore.jsonlz4 does not contain the current tabs, so where are they? After losing all of my tabs I copied the sessionstore-backups. They were quite large. Obviously they must contain my lost tabs. But now the current sessionstore.jsonlz4 has the very same large size. However, the lost tabs do not show up when Firefox is launched! And yet the few tabs – I’ve tried one, two, and three – that were open when Firefox is closed do show up. And the large size of each “new” sessionstore.jsonlz4 does not change at all! BTW I have tried inserting each one of the backups and nothing changes. The current tab or tabs shows up, but not the lost tabs. What is going on?

Since the last update I find while using Google or Duckduckgo browsers that sites will load or are very slow to load. Not all sites but especially new sites. How to we fix this?

Lors de la dernière mise à jour de Firefox, j'ai retrouvé un dossier sur mon bureau appelé "anciennes données de Firefox" Faut-il garder ce dossier ou le mettre dans la corbeille? Merci de votre réponse

I received the following error message when trying to connect with a site which I have been using for several years. The advice below the error message directs me to contact the site owner, but I can't do so if Firefox will not let me access the site. What to do?
