I have an add-on ad blocker for youtube and have never gotten ads. This afternoon that stopped. I get ads with every video I click and there is no 'skip ad' on the screen. I added another top rated youtube add blocker, quit firefox and then opened it again. Before, if I clicked a video it started an ad and I could go back and then hit the video again, but now that doesn't work, but if I select to show the video in a new tab, there are no ads in that tab. What can I do to make the ads stop like they used to and never appear? Yes and my OS is Ubuntu 22.04

How can I set tabs to automatically preload when I open the browser? I'm just trying to switch from Chrome to Firefox and I can't find such a setting here, although it is a very convenient functionality. I mean that when I open the browser, I can click on any of the tabs and it will be (partially or completely) immediately ready to work without additional loading.

Starting with Firefox version 120, you can set Firefox to automatically launch whenever you start or restart your Windows computer. https://support.mozilla.org/en-US/kb/open-firefox-automatically-when-you-start-computer

The browser shows opt-in prompt for the user to easily setup this behavior. However, I do not want to do this.

When I click "No thanks", the prompt goes away, but couple days later, it returns. I guess that an update resets the prompt status.

Is there a way to permanently disable this opt-in prompt without allowing Firefox to start automatically with the computer?

Every time I open Firefox after closing it, I get the message below. I can click the button to restore session and it works every time. With each update, I hope to never see this message again, but after installing a new version on Ubuntu today, I see the same familiar message. This is not linked to a computer, or an operating system because I've seen this on both Ubuntu and Mac. If Firefox could literally just click the button that would be awesome.

Sorry. We’re having trouble getting your pages back.

Nie mogę zalogować się na konto Gmail poprzez stronę www.google.pl w przeglądarce Firefox. Przy próbie zalogowania się przez www.google.pl pojawia się komunikat Bad Request Error 400. Ten sam problem występuje, gdy muszę potwierdzić logowanie do innych stron internetowych za pomocą konta Google. Po prostu nie da się nigdzie zalogować. Ten problem nie występuje w innych wyszukiwarkach. Moderator Firefox odpowiedział -"This does not sound like an issue with Firefox, but is something that the Google support team should be able to help you with" Na stronie www.google.com pojawia się ikona zalogowania, ale i tak nie wszystkie usługi związane z Google są dostępne. Niedostępne są wtedy — Google konto, Google Play, Gmail, Meet, Chat, Dysk, Kalendarz, Zdjęcia, - to tylko te najważniejsze niedziałające." Pliki cookie są włączone. 25.12.2023 ten problem nie istniał. Próbowałam przywrócić Firefox na wcześniejszą datę instalacji, ale to nic nie dało. Rozszerzenia i wtyczki odinstalowałam. Problem niestety pozostał. Bardzo proszę o pomoc. Pozdrawiam Bogaczewicz Bogusława.

So I've been doing this for years now, as a Youtuber I take an image file from File Explorer (Windows 10) and drag it over to upload the thumbnail to Youtube. But for some reason the last few days I can't drop the file, it just stays there with the mouse when I let go of the button. On a random page it should let me drop the file and show the image but it doesn't, and it also won't drop if I try a google image search.

I have tried this on Edge and Chrome and the problem only seems to exist on Firefox.

[My screenshot button hides the mouse in pictures but it's attached to that blue semi-transparent square, trying to drop a file but can't.]

Hi I'm running into an issue where I'm trying to save files while retaining their original filenames, but '%' characters are changed into an underscore when I try to save it. I've tested this with Google Chrome but it doesn't run into this issue. Is there a setting or workaround so that Firefox will leave the filenames alone?

I'm trying to use a manual proxy server for Firefox. When entering the proxy address and port number, Firefox outlines the port number field in red and disables the OK button thus refusing to accept my assigned port number. I'm trying to use port number 29842 which was given to me by the proxy provider.

Using Windows 10 22H2 and Firefox 122.0.1 Yesterday I had no problem opening the map on purpleair.com. Today I can't. Get error:

Error: Failed to initialize WebGL

TypeError: DE is undefined.

But I can open this same website map in Google Chrome browser with no problem. What changed in Firefox and how do I fix it. And why do I need to fix it, since it all works fine in Chrome

Thanks a bunch,

Mike

Support,

The USPS website does not work properly with Firefox!! The Home page loads okay but there are multiple other issues with links not working. For instance all of the links under Quick Tools do not work except this one: https://www.usps.com/manage/po-boxes.htm. Other things don't work either.

Everything works fine that I tried with Google Chrome though! Please address soon.

Thanks

Installed Firefox 122 in a new Windows 10 installation and added some extensions (e.g. Gesturefly, Update Scanner, uBlock Origin, Uppity). These pinned fine on my old installation. But I cannot find how to pin them on the new.

All the help I have found Googling, or using search here, says go to the Add-ons Manager page and right-click the extension and use "pin to toolbar". Alternatively click the extension and click the gear icon and use "pin to toolbar". But when I right-click there is no pin to toolbar context menu entry. If I left-click the gear I get "Check for Updates, View Recent Updates, Install Add-on From File, Debug Add-ons, Update Add-ons Automatically, Reset All Add-ons to Update Automatically, Manage Extension Shortcuts". If I right-click the gear I get a line of icons (left, right, reload, star) followed by "Open Image in New Tab, Copy Image Link, Email Image, Save Page As, Select All, View Pate Source, Inspect Accessibility Properties, Inspect (Q)". If I right-click the extension in the Add-ons Manager page itself, I get a very similar list. In no case is there a pin to toolbar option.

How do I pin an extension, given the above? What have I messed up?

Hi. I am running a 3 monitor setup and I like to keep open quite a few tabs. And two windows of Firefox. So two Firefox instances with several tabs on each. But because it eats a lot of memory, I have to close and reopen Firefox from time to time. And to my annoyance, sometimes it "forgets" about one of the windows. So opens only one instead of both. Therefore I loose some quite important tabs. Any suggestions on how to fix this? Thank you.

Firefox is broken. For months now anytime I watch a Live stream on Youtube it freezes within seconds and acts like it's buffering. Internet connection is great. Same live streams work perfect on Microsoft Edge, Google Chrome and others. Only Firefox browser is doing this.

As the title states. At least half the time when you try right-click and use the "Copy" function, the option is greyed out. If you try to Ctrl+Shift+C, it opens dev tools! This happens on multiple systems that I have that are based on Debian/Ubuntu. So basically, copy functionality is broken for Firefox Linux users...

I tried clearing cache and temp files. I tried a new profile. I tried a fresh install without logging in on account. Tried disabling all addons, running in safemode and incognito. Nothing works.

When opening in Chrome, it works as always. Same computer.

Hi, this is the same issue as as described here for Mozilla Thunderbird: 64bit Thunderbird issues with 64bit PKCS#11 drivers

– Firefox 122.0 (64-bit) – Windows 11 Pro 64bit (– Thunderbird 64bit)

Even though, I use a 64bit version of Firefox, it is not able to load any 64bit PKCS#11 module for security devices. Tried on several different PCs and several different 64bit PKCS#11 drivers for different smart cards.

When I try to load e.g. C:\Windows\SysWOW64\eop2v1czep11.dll for the Czech eID, it returns "Unable to add module". When I do the same from C:\Windows\System32\eop2v1czep11.dll, it works.

The issue is that some issuers of qualified and commercial certificates (like e.g. Komerční banka) do not issue a 32bit version of PKCS#11 drivers for their smart cards anymore and the only driver available is C:\Windows\SysWOW64\mopkcs11.dll, which cannot be loaded by Firefox or Thunderbird either.

I don't see a problem in implementing the support for 64bit PKCS drivers in a 64bit browser and a 64bit email client. And if it does have the support, then there is something wrong going on.

I am using Firefox with the uBlock Origin and Cookie AutoDelete extensions enabled. When I try and load Gmail or any other Google site, I get a blank page and nothing loads at all. This only occurs when my VPN is on (I use Private Internet Access). However, even with the VPN on, Chrome will still load those sites. Disabling the VPN means that the sites load normally.

My guess is it might be some sort of privacy setting in Firefox, but I don't understand what it could be. The only thing that breaks/fixes the sites is connecting and disconnecting the VPN, irrespective of which country I try and connect from.

I assume that it's the same problem as this: https://support.mozilla.org/en-US/questions/1388431 but there is no solution.

https only mode is not active

browser.fixup.alternate.protocol is set to http from https browser.urlbar.autoFill is set to false

Nothing helped.

I get that this default makes sense but since so many local tools don't use http there should be at least 1 working option to disable this behavior at least for certain sites.
